The SmartWay Truck Tool utilizes the most up-to-date emission factors, in combination with detailed vehicle activity data, to estimate emissions and associated performance metrics. The primary purpose of the Tool is to help fleets calculate actual pollutant emissions for specific truck types and applications and track their emissions performance over time. Shippers can, in turn, use the data that truck carriers report using these Tools to develop more advanced emissions inventories associated with their freight activity and to track their emissions performance over time. The Tool allows the user to evaluate fleet performance in terms of different mass-based performance metrics for C02, NOx, and PM (PMio and PlVh.s), including:1 • Grams per mile • Grams per average payload ton-mile • Grams per thousand cubic foot-miles • Grams per thousand utilized cubic foot-miles The Tool can also generate estimates of emissions associated with the total miles, loaded miles, and revenue miles traveled by a fleet. Fleet performance can then be assessed at the truck-class and/or fuel-type level, or on an aggregated basis across all classes and fuels. The Tool also collects extensive information on fleet operations and truck body types, allowing detailed segmentation of Partner fleets for more appropriate, equitable comparisons. For example, fleets that cube-out with low payloads (e.g., those hauling potato chips) will be able to compare themselves to similar fleets on a simple grams per mile basis, rather than a mix of fleets that includes fleets that routinely weigh-out. Similarly, fleets that operate in primarily short-haul, urban environments at relatively low average speeds will have fundamentally different emission rates and constraints than 1 At this time the Truck Tool does not calculate performance metrics for specialty fleets that track their activity in terms of hours of use rather than miles traveled or freight hauled (e.g., refuse haulers and utility fleets). Future modifications may be made to the current Tool to accommodate such fleets. 1 ------- long-haul fleets operating at highway speeds. By collecting detailed information on fleet operations (short vs. long, TL vs. LTL, urban vs. highway, etc.), as well as truck class (2b through 8b) and body type (dry van, reefer, flatbeds, etc.), individual fleets can compare their performance to other, similar fleets, which can help them to better manage their emissions performance. ------- The SmartWay Truck Tool user provides most vehicle characteristic, operational, and activity data needed for emissions performance estimation (see Section 3 for more information). The Tool calculates emissions by multiplying fleet activity data with EPA- approved emission rate factors that are stored in look-up tables within the Tool. The Tool contains different types of emission rate factors for different pollutants. C02 factors are expressed in grams of C02 per gallon of fuel2'3 NOx and PM factors are expressed in grams of pollutant per mile traveled for operating emissions, and in grams per hour for idle emissions. In general, C02 factors are independent of the truck types, classes, and operational practices in a fleet. NOx and PM factors, however, vary depending upon a number of parameters, including: • Truck class • Engine model year/emission certification standard • Vehicle speed • Vehicle driving pattern (referred to as "drive cycle") In addition, PM emissions will also vary with the application of PM control retrofits, including diesel oxidation catalysts (DOC), closed crankcase ventilation (CCV), and diesel particulate filters ("PM traps" or flow-through filters). In the Tool, PM control retrofits are assumed to have the same impact on operating and idle emission factors.4 2.1 COi Factors EPA populated the SmartWay Truck Tool with C02 factors that are based on fuel consumption. These factors and their sources and are summarized below in Table 1. 2 At this time other greenhouse gases such as methane (CH4), nitrous oxide (N2O) and black carbon are not included in the current Truck Tool. 3 The Truck Tool also estimates emissions associated with battery-electric trucks. In this case pollutant emissions (CO2, NOx and PM) are determined based on the kWhrs used for charging. 4 Future versions of the Tool may account for differences in retrofit effectiveness for running versus idle emissions. ------- Table 1.

The Tool then adds the emissions from each blend component together to determine total C02 emissions. Therefore emission factors for specific blend ratios are not needed for C02.6 Within the Tool, users may provide their CNG fuel use estimates in terms of gasoline- equivalent gallons (on a Btu basis), or in standard cubic feet (scf). If CNG consumption is expressed in scf, the Tool applies a fuel factor expressed in grams per scf (57.8), based on 983 Btu/scf and 58,819 g C02/mmBtu.7 2.2 NOx and PM Factors The SmartWay Truck Tool contains NOx, PMio and PlVh.s emission factor outputs for on-road operation from EPA's MOVES2014a model for gasoline, diesel, and E10 for all 5 i) Final Rule on Light-Duty Vehicle Greenhouse Gas Emissions Standards and Corporate Average Fuel Economy Standards (75 FR 25324, May 7, 2010).

The emission factors are broken out by general drive cycle type (urban or highway), and average speed range, as discussed below. Short-duration (less than 15 minutes) idle emission factors for NOx and PM were developed separately by model year, truck class, and fuel type (diesel and gasoline). MOVES2014a does not currently provide short duration idle factors in terms of grams per hour, so MOVES2014a was run using the Project Level scale with a single link and with an average speed of zero. Runs were performed for typical winter and summer conditions, taking the average of outputs from those runs to obtain g/hr factors. MOVES2014a does provide emission factors for long-duration idle for long-haul diesel trucks. These factors are applied separately to the long-duration idle hour estimates provided for Class 8b trucks within the Truck Tool.8 Short-duration factors are applied across the board for the remaining truck class types. Note that hybrid electric trucks are assumed to have no short-duration idle emissions (due to assumed engine auto-shut off), although long-duration idle (and regular exhaust9) emissions are assumed unchanged relative to their conventional vehicle counterparts. Finally, battery-electric trucks are assumed to have no idle emissions. The resulting idle factors are presented in Appendix B. Version 2.0.15 of the Truck Tool also calculates the NOx and PM emissions associated with use of transportation refrigeration (reefer) units. EPA's NONROAD2008a emissions model was used to develop emission rates for these units for the 2014 calendar year, following these steps: • Three A/C refrigeration (reefer) unit standard classification codes (SCCs) were identified within the NONROAD model - 2265003060 (gasoline); 2268003060 (CNG); and 2270003060 (diesel); • A national average model run was performed for these three fuel types for 2014; • Tons per year outputs were converted to grams per year for each horsepower (hp) bin grouping, for each fuel type, for NOx, PMio and PlVh.s; • Grams/gallon factors were calculated for each hp bin by dividing grams/year by gallons/year, for each fuel type, for NOx, PMio and PIvh.s; • Weighting factors were applied to the gram per gallon factors for each hp bin. These weighting factors reflected relative emission impacts across the different 8 NOx factors for long-term extended idling are higher than short-duration factors (at least for late model engines), since engine operation temperatures and loads at idle are generally not high enough to activate late-model emission controls such as SCR and EGR. 9 While there is evidence that NOx emissions may be decreased through the use of hybrid electric technology, EPA has not performed emission testing to assess this effect. Therefore hybrid NOx and PM exhaust emission rates are assumed to equal conventional vehicle equivalents in the current Truck Tool. ------- hp bins, accounting for differences in equipment population, hours of use, and engine load factors. For a given hp bin, the weighting factor is expressed as: weighting factor = pop x avg hp x hrs/year x engine load factor • Weighted g/gal factors were summed across hp bins for each fuel type and pollutant to obtain the final, national fleet-average fuel factors for reefers. Table 2 provides the NOx and PM fuel factors used in the latest Truck Tool. Table 2. Weighted Average Reefer Fuel Factors (g/gallon) Fuel Diesel Gasoline CNG NOx 62.026 16.369 17.732 PM™ 4.044 1.010 0.790 PM2.5 3.922 0.929 0.790 The next section describes the process followed to select the on-road emission factors from MOVES2014a for use in the Truck Tool. Emission factors in grams per mile were developed for gasoline, E10, and diesel fuel types for all MOVES source types that correspond to MOBILES heavy duty vehicle classes, 2b-8b inclusive. The MOVES source types modeled are shown in the table below. Of these, school buses, refuse trucks and motor homes represent only a small fraction of total activity. Table 3. MOVES Source Types Associated with Class 2b - 8b Vehicles Source Type ID 31 32 43 51 52 53 54 61 62 Source Type Name Passenger Truck Light Commercial Truck School Bus Refuse Truck Single Unit Short-haul Truck Single Unit Long-haul Truck Motor Home Combination Short-haul Truck Combination Long-haul Truck Separate factors were developed for "Urban" and "Highway/Rural" roadway types. These factors were apportioned according to MOVES operating mode groups, which correspond to speed ranges of 0-25 mph, 25-50 mph, and 50+ mph. Emission factors calculated by the model, output by MOVES source type, were then converted to a MOBILES vehicle class basis. In this way, the Truck Tool can select appropriate emission factors for use by: ------- • weight class • model year • road type (urban vs. highway/rural) • speed distribution The following describes the methodology for the emission factor calculation. Calculation of MOVES emission factors by operating mode In calculating emission factors, the primary goal is to disaggregate factors by the percentage of time a given type of vehicle spends operating at certain speeds. The ranges of speeds analyzed include 0-25 mph, 25-50 mph, and greater than 50 mph. These speed ranges correspond to MOVES operating modes #11-16, 21-29, and 30-40 inclusive, where each operating mode is defined by both the speed of the vehicle and its vehicle specific power (VSP). First, for a given source type and model year, the fraction of emissions attributable to each range of speed was determined. Emissions for a vehicle can be expressed in Equation 1: Equation 1 E' = AiEf + A2E2' + A3E3' + AiEi + AeEe Where: E' = unconnected10 mass emissions calculated based on operating mode and emissions contribution by speed bin Ai-s = the sum of activity fractions (in seconds) over speed range n. (Ai and AB represent the activity associated with the individual operating modes for idling and braking, respectively.) £1-3' = the weighted average emissions over a given speed range n. (Ei and EB represent the emissions associated with the individual operating modes for idling and braking, respectively.) The following figure shows a range of emissions and activity fractions for an example source type and model year. The operating mode (or VSP bin) are shown on the x-axis. The dashed red line presents the fraction of vehicle activity associated with a given operating mode, while the black circles present average HC emissions for each operating mode. 10 Subsequent adjustment factors are presented in Equation 3 below. 7 ------- Figure 1.

This table contains operating mode fractions by source type, roadway type, average speed bin, and pollutant/process. The fractions from this table are normalized using average speed distributions from the "avgspeeddist" table, and the sum of the normalized operating mode fractions in each speed bin constitutes An. En' is derived from data obtained from the default MOVES "emissionratebyage" table. This table contains emission rates by pollutant process, operating mode, and age group for a wide variety of sourcebinlDs. For this analysis, a MySQL query was used to select sourcebinlDs corresponding to the source type, fuel type, and calendar year of interest, and limited our rate selection to the 4-5 year age group. The emissions obtained here were then converted to a source type basis (from their current sourcebinID basis); this was done by retaining the "sourcebindistribution" table from the MOVESExecution database, which is created by the Source Bin Distribution Generator (SBDG) during each MOVES run, and weighting the activity fractions for each source type and model year combination in this table with the data from the "emissionratebyage" table described above. Having finished this mapping, an emission rate is generated, by source type and model year, for each operating mode (corresponding to the circles in the figure above). Since En' for each speed range represents the average emissions of the range weighted by the activity in that range, the weighted average emissions can be calculated from the 0-25 mph speed bin, E-f, as follows in Equation 2: ------- Equation 2 E ^= ^11^11 + R\lTu +^13^13 + ^14^14 +^15^15 1 16 Where: Rn = The activity fraction for operating mode n, obtained from the "opmodedist2" table Tn = The emissions for operating mode n. Other speed bins will use different operating modes in their calculations; the equation above is merely an example illustrating the calculation method for the first speed bin. Having calculated an appropriate En' for each speed range for a given source type and model year, Equation 1 can be used, along with the appropriate activity fraction, to arrive at a total uncorrected emissions value. In and of itself, this emission factor has little value in estimating emissions. However, it can be used along with the modeled emission factor for a particular source type and model year to arrive at an overall adjustment factor, as shown in Equation 3: Equation 3 "E7 Where: E = The modeled emission, obtained from MOVES outputs, for an individual source type and model year E'= The uncorrected emissions for an individual source type and model year, calculated using operating mode distributions and emission factors from the "emissionratebyage" table This overall adjustment factor, in turn, can be applied to each individual emissions component, En', as shown in Equation 4: Equation 4 En = ZEn' The adjusted emissions, En, are subsequently used to calculate a total, corrected emission factor for a given source type and model year combination, as described by Equation 5: Equation 5 E = AiEi + A2E2 + AaEa + AiEi + AeEe ------- In this way, a representative emission factor is calculated by operating mode/speed group. This will allow the Truck Tool to adjust the default operating mode percentages (An) to more accurately represent a user-provided speed profile for the vehicles they are evaluating. Default operating mode percentages may also be used, as calculated above. Conversion of Emission Factors from Source Type to Weight Class Basis Ultimately, emission factor lookup tables are required for use in the Truck Tool by weight class, fuel type, and model year. However, modeled output from MOVES is aggregated by source type. Therefore a post-processing Tool was developed to convert vehicle emission factors from source types to weight class based on internal MOVES tables. The conversion methodology used in this Tool is described below. First, the adjusted emissions and activity output from MOVES are combined, by pollutantID, by joining the "movesoutput" and "movesactivityoutput" tables by calendar year, source type, fuel type and model year. The sourcetype and model year for each record are combined in a new field, sourcetypemodelyearlD. Next, the emissions and activity output from the first step are combined with the MOVES "sizeweightfraction" table by joining on the sourcetypemodelyearlD. The "sizeweightfraction" table contains, for a given combination of source type and model year, the fraction of vehicles apportioned across weightclasslD. Given the weightclassID, the portion of emissions and activity attributable to a given range of vehicle weights is determined, and subsequently, those weights (along with fuel type) are mapped back to MOBILES vehicle classes, which are based on GVWR. (This is achieved with a separate lookup table, "MSVehType", which is derived from Appendix B, Table 3 of the EPA's MOBILE6.2 User's Guide.) For each calendar year, sourcetypemodelyearlD and pollutantID, the sizeweightfraction is multiplied by the emissions (in grams) and activity (in miles) to obtain EmissionFrac and ActivityFrac, respectively. Finally, the EmissionFrac and ActivityFrac calculated above are summed by yearlD, pollutantID, fueltypelD, and MOBILES vehicle type (e.g., HDDVSb). This provides total emissions and activity independent of the MOVES source type or vehicle model year. Finally, the aggregated emissions are divided by the activity to arrive at g/mi emission factors, presented in Appendix A. Modeling E10 Emission Rates In a MOVES run that uses nationwide defaults for fuel supply, the model includes dozens of fuel formulations on a by-fuel region basis in its calculations. In addition to diesel fuels, many counties in the model defaults are characterized by varying market shares of and E10 and E15 (usually about 97.5% and 2.5%, respectively In order to isolate Gasoline emission factors, the new Fuels Wizard included in MOVES2014a was used to alter the ethanol percentage of fuels nationwide to zero. 10 ------- Thus, separate E10 and gasoline MOVES runs were then performed using the newly updated information. Sensitivity Analysis Results The relative emissions impact of different speed regimes were evaluated for four road types - urban arterial, urban freeway, rural arterial, and rural freeway. To simplify the sensitivity analysis, MOVES outputs were generated for diesel long-haul combination trucks, model year 2012, run for the 2014 calendar year, using national average defaults (e.g., fuel specifications, temperatures, etc). The results of the analysis are shown for NOx and PM2.5 below. Figure 1 1 8 - 1 ft - 1 A - 1.2 - I 1 - G) 0.8 - n ft - 0.4 - 0.2 - Default NOx Contribution by Speed Bin E = F Urban Art • IDLE DBRAK D5070 • 2550 D0025 Urban Frwy Rural Art Rural Frwy Road type 11 ------- Figure 2 Default PM2.5 Contribution by Speed Bin Urban Art Urban Frwy Rural Art Road type Rural Frwy As shown in the above charts, the emissions for urban freeways, rural arterials, and rural freeways are all heavily dominated by high speed (50 - 70 mph) operation.11 In addition, actual emission levels are relatively insensitive to road type across these three types. However, speed distribution appears to have a significant bearing on emissions for urban arterial operation. Accordingly, the recommendation for Truck Tool application was to develop fully disaggregated emission factor look up tables (retaining all four road types), and then weight urban freeway, rural arterial, and rural freeway road type operations in order to aggregate emission lookup tables within the SmartWay Tool to reflect "urban" (i.e., urban arterial) and "other" road types. In addition, under this approach users can choose default speed distributions for these selections, or specify the percent of operation by major speed range (0 - 25, 25 - 50, 50 - 70). Given the relative insensitivity to speed for the "other" category, specifying speed distributions would only be permitted for urban arterial operation. Under this approach, the user is given the follow input options: • Specify % Highway/Rural ("other") operation fraction • Specify % urban operation distribution by speed bin, or select "default speed distribution" Data entry is handled through the addition of a popup screen for non-default selections (see the Truck Tool User Guides for details). 11 This finding is consistent with the 2008 SmartWay Partner data submissions, wherein 87% of Partners selected the 50+ mph category as the most representative of their non-urban operations. 12 ------- 2.3 Alternative Fuels NOx and PM emission factors are not available from MOVES2014a for certain alternative fuels, including biodiesel, E85, natural gas, and LPG. Accordingly, EPA used adjustment factors from a number of sources described below to estimate NOx and PM factors for these other fuels. NOx and PM emission factors for biodiesel were based on the findings from an EPA study, A Comprehensive Analysis of Biodiesel Impacts on Exhaust Emissions (EPA420- P-02-001, October 2002). This study developed regression equations to predict the percentage change in NOx and PM emission rates relative to conventional diesel fuel, as a function of biodiesel blend percentage, expressed in the following form: Equation 6 % change in emissions = {exp[a x (vol% biodiesel)] -1} x 100% Where: a = 0.0009794 for NOx, and a = -0.006384 for PM Using Equation 6, adjustment factors were developed for biodiesel blends based on the percentage of the biofuel component,12 and then these adjustment factors were applied to the appropriate conventional diesel emission factors in Appendix A (see Section 2.2 for the sources of conventional diesel emission factors). Note that the fleet-average blend value is assumed to be the same for all truck classes, since the biofuel consumption data is not collected at the truck class level. (This assumption holds for ethanol consumption data inputs as well.) For gasoline-ethanol blends, the SmartWay Truck Tool only accepts fuel consumption estimates for E10 and E85 since, unlike biodiesel where the biofuel fraction can vary significantly, ethanol is generally blended with gasoline at two discrete levels: 10% (E10) and 85% (E85). As discussed in Section 2.2 above, NOx and PM factors for E10 were output directly from MOVES2014a. Given the lack of heavy-duty E85 test data, adjustment factors for E85 were based on emissions estimates for light-duty vehicles cited by the US DOE Alternative Fuels and Advanced Vehicles Data Center.13 These estimates come from a technical paper published in the Journal of Air & Waste Management.14 Relative to conventional gas vehicles, the authors of this paper estimate that vehicles running on E85 provide an average NOx reduction of 54% (based on 73 vehicle tests), and an average PM reduction of 34% (based on 3 vehicle tests). These adjustment factors are applied to the appropriate gasoline engine emission factors in Appendix A to develop emission factors for E85. 12 Biodiesel blend percentage is calculated by dividing BlOO-equivalent gallons by total fuel gallons at the fleet level - see the Track Tool User Guides for details regarding biodiesel use inputs. 13 See http://www.afdc.energv.gov/afdc/vehicles/emissions e85.html. last validated December 22, 2011. 14 http://www.afdc.energv.gov/afdc/pdfs/technical_paper_feb09.pdf. 13 ------- If the consumption level of E10 is unknown, the Truck Tool user may also specify national average default blend levels for ethanol. National totals for gasoline use for 2012 were obtained from the Energy Information Administration's (EIA) Annual Energy Outlook Reference Case for 2013, Table 37 (Transportation Sector Energy Use by Fuel Type within a Mode). Summing the energy use values for light-duty gasoline vehicles, commercial light trucks, and freight trucks from the table yields an estimate of 16,040 TBtu (15,315 + 336 + 389) for 2012. National fuel ethanol consumption estimates for 2012 were also obtained from the EIA, totaling 1,064 TBtu (see Table 10.3, consumption minus denaturant in http://www.eia.gov/totalenergy/data/monthlv/pdf/sec10 7.pdf). Assuming 114,100 Btu/gallon of gasoline, and 76,100 Btu/gallon of E100,15 ethanol is estimated to constitute 9.05% of gasoline fuel consumption in the U.S., on a volumetric basis.16 Emission adjustment factors were used for gaseous fuels (LPG, CNG and LNG) that were cited by the Alternative Fuels and Advanced Vehicles Data Center, Table 2: NREL/UWV Field Tests of Natural Gas Vehicle Emissions.17. These factors were developed by the National Renewable Energy Lab and University of West Virginia based on field studies on natural gas vehicles. For this assessment, it was assumed that CNG and LNG emissions were identical. In addition, it was also assumed LPG vehicle emissions would be equal to natural gas vehicle emissions.18 To be conservative, the smallest emission reduction estimates were selected from Table 2 (86% for PM and 17% for NOx) relative to comparable diesel vehicles. These adjustment factors are then applied to the diesel emission factors in Appendix A for to develop emission factors for these fuels. The same adjustment factors are applied for all model years in the Truck Tool because model year-specific emissions data do not appear to be available at this time. Note, however, that the emissions from the combustion of alternative fuels may be different for older trucks (with minimal emission controls) and newer trucks (with extensive control systems in place) due to vehicle emission standards. Emission estimates for battery-electric trucks are based on national average electric generation mix profiles from USDOE's GREET model, as described in Appendix C. 2.4 PM Control Effectiveness The Truck Tool applies adjustment factors to the PM emission factors in Appendix A and B for any pre-2007 diesel truck for which Partners have installed a specific retrofit 15https://www.afdc.energv.gov/afdc/prep/popups/gges.html. last verified 12-22-11. 1616,040 TBtu gasoline x 1012 Btu/TBtu /114,100 Btu/gal= 1.41 x 1011 gallons of gasoline; 1,064 TBtu E100 x 1012 Btu/TBtu / 76,100 Btu/gal = 0.140 x 1011 gallons of E100; 0.140 / (1.41 + 0.140) = 9.05%. Note this methodology disregards the relatively small volumes of ethanol consumed as E85. 17 http://www.afdc.energv.gov/afdc/vehicles/emissions natural gas.html. last validated 12-22-11. 18 The PM and NOx estimates cited by this source for LPG vehicles were actually slightly lower than for natural gas vehicles - http://www.afdc.energy.gov/afdc/vehicles/emissions_propane.html. However, based on engineering judgment it was assumed that LPG PM and NOx emissions would be similar to comparable CNG vehicles. 14 ------- control device. The following adjustment factors were obtained from EPA OTAQ (presented as a % reduction in emissions; see Section 3.2 below for details): • Diesel oxidation catalyst (DOC) - 25% • Closed crankcase ventilation (CCV) - 5% • Diesel particulate filter (DPF) - 90% The Tool applies these adjustment factors to pre-2007 PM operating and idle emission estimates. The Tool also allows for situations where CCVs are applied in combination with either DOCs or DPFs. In such a case, the reduction effectiveness is calculated additively. For example, if pre-control operating emissions were 1.0 g/mile for a diesel truck, and a CCV and DOC were applied, the resulting emission rate would be: Equation 7 1.0 x [1 - (0.25 + 0.05)] = 0.07 g/mile, post-control However, the Truck Tool assumes that DOC and DPF application are mutually exclusive. 15 ------- 3.0 The emission rates and adjustment factors discussed above are combined with appropriate activity data (provided by the Partners) to calculate mass emissions at the fleet and/or partner level for C02, NOx and PM, as described below. 3.1 COi C02 is calculated within the Truck Tool utilizing emission factors expressed in grams per gallon of fuel, (with the exception of battery-electric trucks), as discussed in Section 2.1 above. The general equation for calculating C02 emissions using reported fuel consumption values is Equation 8 Eco2 = ((F - B) xEFF) + (B x EFB) Where: £002 = grams CC>2 per year F = Fossil Fuel (Gallons per year) B = Biofuel (Gallons per year) EFp = Fossil Fuel Emissions Factor (g/gal based on fuel type) = Biofuel Emissions Factor (g/gal based on biofuel type) Emissions for all pollutants for battery electric trucks are calculated by multiplying the reported kWhrs used for charging by the associated g/kWhr factor (see Appendix C). In most instances reefer fuel is aggregated with vehicle fuel inputs in the Truck Tool, with the reefer fuel type assumed to be the same as the vehicle fuel type. However, reefer units associated with LPG and electric trucks are assumed to use diesel fuel (by far the most common type of reefer engine). Accordingly, any reefer fuel use reported for LPG and electric trucks is included in the total C02 calculation using the diesel fuel factors in Equation 8. Fuel Allocator The Truck Carrier Tool asks users to enter Gallons of Diesel Used by truck class in order to estimate C02 emissions. This information may be entered directly if available. However, if the user does not have this information but does know total fuel use and MPG by truck class, the Truck Tool's Fuel Allocator can be used to apportion fuel use across truck classes. In the Fuel Allocator, the user enters total fuel consumption and truck class MPG estimates. The allocator then calculates the fuel used for each class based on the total fuel and class MPG. If the total fuel calculated matches the total fuel entered to within 2%, the allocator indicates a "Match". However, instead of writing the exact calculated value seen in the Fuel Allocator to the Activity screen, the Tool adjusts the class fuel 16 ------- amounts (and therefore MPG) so the sum matches the Total Fuel entered exactly, and then writes these values on the Activity screen. That means, the MPG entered into the Fuel Allocator, and the calculated fuel used seen on the Fuel Allocator, are not necessarily equal to the MPG and the fuel used that is written to the Activity Screen. If the user re-opens the Fuel Allocator at this point, the Allocator brings in the MPGs listed on the Activity Screen, NOT the MPGs the user input into the calculator the first time (although it doesn't overwrite the saved MPGs entered on the worksheet, if the user presses Cancel). For remaining calculations in the Tool, the values shown on the Activity Screen are used. The Allocator values the user entered are saved for the XML file, but aren't used for further calculations. Separately in the XML, the MPG and fuel totals that were put onto the Activity Screen are also written. 3.2 NOx and PM Unlike C02 emissions which only vary with fuel type, NOx and PM emission rates also vary substantially depending upon engine model year and/or emission certification level, vehicle class, drive cycle, speed, and operation mode (running or idle). For this reason, EPA developed lookup tables in the Truck Tool with emission factors that correspond to user-supplied inputs regarding their fleet activity. The NOx and PM emission rates expressed in grams per mile were combined with the appropriate mileage metric (i.e., total miles) in order to estimate mass emissions. The general equation for calculating NOx emissions is as follows: Equation 9 ENOX = (Mc x ((GPMH x HOC) + (GPMui x UDCi) + (GPMU2 x UDC2) + (GPMus x UDC3) + (GPMU4 x UDC4))) x TCY/ TCT) + (GPH, xH, x TCY) Where: ENOX = grams NOx per year for a given truck class Me = Miles driven for Truck Class C per year GRMh = Grams/mi (by truck class & engine yr) for Highway/Rural Driving HOC = Highway drive cycle % (% of miles under highway/rural driving) GPMui/2/3/4 = Grams/mi (by truck class & engine yr) for Urban Driving by mode (1 = 0-25 mph; 2 = 25-50 mph; 3 = 50+ mph; 4 = deceleration) UDCi/2/3/4 = Urban drive cycle % (% of miles under urban driving conditions, by mode (1,2,3,4)) TCY = Number of trucks for a given Class/Year combination TCT = Number of trucks total for a given Class GPHi = Grams per hour (by truck class & engine year) for Idling19 HI = Hours of Idling per year (average per truck per year by class) 19 As discussed in Section 2 above, separate emission factors are applied for Class 8b diesel trucks to differentiate short- and long-duration idling. In addition, hybrid electric trucks are assumed to have no short-duration idling emissions, while battery-electric trucks have no idling emissions of any kind. 17 ------- PM emissions for non-diesel vehicles are calculated using an equation identical to that for NOx, utilizing PM emission factors. PM emission for diesel vehicles may be adjusted for PM control effectiveness, as shown below. Equation 10 EPM = (((Mc x ((GPMH x HOC) + (GPMui x UDCi) + (GPMU2 x UDC2) + (GPMus x UDC3) + (GPMU4 x UDC4))) x TCY/ TCT) + (GPH, xH, x TCY)) x (1 - ((0.25 x TDOC / TCT) + (0.05 x Tccv / TCT) + (0.9 x TDPF / TCT))) Where: EPM = grams PM per year for a given truck class TDOC = Number of trucks using Diesel Oxidation Catalysts by class Tccv = Number of trucks using Closed Crankcase Ventilation by class TDPF = Number of trucks using Diesel Particulate Filters by class 0.25 = Effectiveness of DOCs (25%) at reducing particulate matter 0.05 = Effectiveness of CCVs (5%) at reducing particulate matter 0.9 = Effectiveness of DPFs (90%) at reducing particulate matter Note the above calculation methodology assumes that the same highway/urban drive cycle fractions apply across all model years of a given truck class. Similarly, the method assumes that estimated idle hours apply equally to all model years of a given truck class. The above methodology also utilizes estimates for the fraction of miles traveled associated with different road types and speed categories, as shown in the equations above. The Truck Tool user must provide an estimate of the percent of total miles associated with highway/rural driving for each truck class. The user may also provide percentages for the miles spent driving in urban conditions (e.g., unrestricted access, surface roads in well-traveled urban areas), for different speed categories (0-25125- 50 / 50+ mph). This information may be obtained from analysis of truck ECM or possibly GPS data. If urban speed distribution data is not available, the user may select to use default distributions, obtained from the MOVES model. The default speed distributions for urban operation (as defined in Section 2.2 above) varies with vehicle class and model year. However, the variation over model years is very slight (typically with a range of 1 to 2 percent for the largest speed category), the percentages were averaged over all model years for a given speed category/vehicle type combination for use within the Truck Tool. Table 4 presents the resulting default urban speed distributions by speed category for each truck class, for both diesel and gasoline vehicles. Note that the Truck Tool utilizes the diesel default speed distributions for LPG, LNG, and CNG. 18 ------- Vehicle Class Speed Group Percent by Class Diesels HDDV2b HDDV3 HDDV4 HDDV5 HDDV6 HDDV7 HDDVSa HDDVSb 0-25 25-50 50+ Deceleration 0-25 25-50 50+ Deceleration 0-25 25-50 50+ Deceleration 0-25 25-50 50+ Deceleration 0-25 25-50 50+ Deceleration 0-25 25-50 50+ Deceleration 0-25 25-50 50+ Deceleration 0-25 25-50 50+ Deceleration 35% 38% 13% 15% 41% 36% 12% 11% 42% 35% 12% 11% 42% 35% 12% 11% 42% 35% 12% 10% 42% 35% 12% 10% 44% 35% 12% 9% 45% 34% 12% 8% Gasoline Vehicle Class HDGV2b HDGV3 HDGV4 HDGV5 HDGV6 HDGV7 HDGVSa HDGVSb Speed Group 0-25 25-50 50+ Deceleration 0-25 25-50 50+ Deceleration 0-25 25-50 50+ Deceleration 0-25 25-50 50+ Deceleration 0-25 25-50 50+ Deceleration 0-25 25-50 50+ Deceleration 0-25 25-50 50+ Deceleration 0-25 25-50 50+ Deceleration Percent by Class 43% 31% 10% 15% 45% 34% 11% 11% 45% 34% 11% 10% 46% 33% 10% 11% 46% 33% 10% 11% 45% 32% 10% 14% 45% 34% 11% 10% 43% 31% 10% 15% Table 4. Default Speed Category Distributions by Vehicle Class for Urban Operation (MOVES2010a basis)20 As seen in the above table, the MOVES model assumes that some fraction of vehicle operation is associated with "deceleration" events, evaluated independently from other operation due to their unique emission rate patterns.21 However, it is assumed that 20 These values represent the urban component of driving only. If the user specifies a non-zero percentage for Highway/Rural driving, the values in the above table are automatically renormalized, so as to make the sum across urban and highway operation modes equal to 100%. 21 MOVES also assigns some fraction of emissions to idle operation. However, operating fractions and emission factors associated with idle in MOVES outputs are expressed in grams per mile rather than grams per hour. Thus, in order to utilize the grams per hour emission factors developed especially for use in the Truck Tool, MOVES outputs associated with idle operation were removed and the operating mode fractions for the four remaining categories were renormalized to equal 100%. 19 ------- most Truck Tool users will not know their fleet's deceleration fraction. As such, the Truck Tool will adjust any values input by the user to include a deceleration fraction based on MOVES model percentages. If the user selects the default urban speed distributions, the Truck Tool will adjust the urban values from Table 4 to account for the percentage of miles specified for Highway/Rural operation as well. The following provides an illustrative example for calculating PM emissions for diesels given a specific set of road type/speed category distributions. NOx emission calculations follow the same procedure. 20 ------- User specifies 1 Class 8b diesel, model year 2011, traveling 100,000 mi/yr. User specifies the following Road type/speed category distributions: 40% highway/rural 30% 0-25 mph 20% 25-50 mph 10% 50+ mph For highway/rural operation, the lookup value from MOVES is 0.0195 g/mi for PM2.5 For urban operation, the lookup values are as follows: 0-25: 0.031 g/mi 25-50: 0.052 g/mi 50+: 0.012 g/mi deceleration: 0.002 g/mi Now the urban speed distribution percentage inputs must to account for deceleration, as follows: 0-25: 30% x sum of default percentages for the three speed bins (but excluding default deceleration fraction) = 30% x (45% + 34% + 12%) = 27.5% 25-50: 20% x sum of default percentages (45% + 34% + 12%) = 18.3% 50+: 10% x sum of default percentages (45% + 34% + 12%) = 9.2% deceleration: the remaining percentage, which equals 100% - 40% (highway) - 27.5% -18.3% - 9.2% = 5.1% Now apply these percentage weights to the total mileage, and then multiply by the corresponding emission factors to obtain mass, as follows: Highway/rural component: 0.40 x 100,000 x 0.0195 = 780 grams 0-25 urban component: 0.275 x 100,000 x 0.031 = 826 grams 25 - 50 urban component: 0.183 x 100,000 x 0.052 = 952 grams 50+ urban component: 0.092 x 100,000 x 0.012 = 110 grams Deceleration urban component: 0.51 x 100,000 x 0.002 = 10 grams Therefore total = 2,678 grams of PM2.5 (This value will then be summed with any other model year/vehicle class combinations and converted to short tons.) 21 ------- As discussed in Section 2.3, the Truck Tool assumes that B100-equivalent biodiesel volumes are distributed proportionately across all diesel vehicle classes. For example, if a fleet uses 100 B-100 equivalent gallons of biodiesel, and 1,000 gallons of fuel total, the Tool assumes that B10 (100 /1,000 = 10%) is the blend used by each truck class. Accordingly, emission rate adjustment factors are calculated for B10 using Equation 6, and applied to the diesel emission factors for each vehicle class. Emission calculations for ethanol blends follow a different methodology, however, applying discrete emission factors for gasoline and E10 from MOVES (and adjusted gasoline emission factors for E85) with the specific fuel volume estimates provided by the user. The following provides an example illustrating how the miles of travel are apportioned across different blend volumes, in order to estimate mass emissions. User specifies 1,000 gallons of fuel total, and 10,000 miles of travel total User inputs: 100 gallons of E10 100 gallons of E85 Therefore there are 800 gallons of pure gasoline (1,000 - 100 -100) Apportion the 10,000 miles of travel across the different blend levels using gasoline-gallon equivalent (gge) factors (from https://www.afdc.energy.gov/afdc/prep/popups/QQes.htmn as follows: 100 gallons of E10 is equivalent to 100/1.05 = 95 gallons of gasoline* 100 gallons of E85 is equivalent to 100/1.39 = 72 gallons of gasoline Therefore there are 800 + 95 + 72 = 967 gasoline equivalent gallons of fuel, total. Applying the energy-equivalent fuel volume ratios to the 10,000 miles of total travel: gasoline (EO) miles = 10,000 x 800/967 = 8,273 miles E10 miles = 10,000 x 95/967 = 982 miles E85 miles = 10,000 x 72/967 = 745 miles Finally, multiplying these mileage values by the appropriate EO and E10 gram/mile emission factors from MOVES results in the desired mass emission estimates. Similarly, multiplying the E85 miles by the E85 emission factors (adjusted from EO factors as discussed in Section 2.3, provides mass emissions associated with E85). * E10 gge factor developed from linear interpolation of E100 and gasoline Btu/gallon values In addition, if national default ethanol blend levels are specified for gasoline fuel use, the Truck Tool assumes that all ethanol consumed is in an E10 blend. For example, assuming 1,000 gallons of gasoline are specified by the user, there would be 905 gallons of E10 (1,000 x .905 - see Section 2.3), and 95 (1,000 - 905) gallons of gasoline. Mass emissions would then be calculated for the gasoline and E10 components of the fuel as in the above example, apportioning total miles across gasoline and E10 in order to apply the appropriate g/mi factors. 22 ------- Finally, note that the PM factors output by the MOVES model for use in the Truck Tool are expressed in terms of PM2.5. The MOVES model assumes a fixed ratio of PMio / PM2.5 for a given fuel type, as summarized below: • Gasoline-1.086 • Diesel-1.031 • CNG-1.000 These factors were applied directly to the PM2.5 emission factors to obtain mass emission and performance metrics for PMio within the Truck Tool. In addition, it was assumed that LNG and LPG had PM ratios equivalent to the CNG value (1.00). Ethanol was assumed to have a ratio equal to that for gasoline, while the ratio for biodiesel was assumed to equal that for diesel. 3.3 Activity Calculations The Truck Tool requires users to provide specific activity information on fuel consumption, miles traveled, payload, cargo volume, average used cargo volume %, road type/speed, and idle hours at the vehicle class level for the emissions performance assessment (see Section 4.0 below). While the user may provide direct data inputs for any or all of these activity parameters, the Truck Tool also allows the user to select default values for payload and volume determination, in the absence of fleet-specific information. (Direct inputs for payload are highly preferred over the use of calculator defaults.) The data sources and assumptions used to develop these default values are discussed below. Default Payload Distributions Average payloads can vary widely among fleets, even within a given vehicle class, depending upon commodity type and body/trailer type. With the exception of LTL and Package carriers, and Class 8b auto, moving and heavy-bulk carriers (see below), exact data entries were used from the 2011 Truck Tool submissions to obtain payload distributions for the 2015 Tool. This data was categorized by fuel type, truck class, body-type, and SmartWay ranking category. Body-type refers to the categories presented in the Truck Tool payload calculator (e.g., Step Van, Beverage, Combination Flatbed, etc.). Ranking category is based on the Fleet Description inputs (e.g., Truckload Dry Van, Dray, Mixed, etc.). 1,850 unique records were identified using this categorization of the 2011 Partner data. This data was then reviewed and four outliers were identified and removed from the data set.22 Next, the data was grouped by truck class and body type and examined for notable differences in payload values across ranking categories. However, with the exception of certain Class 8 trucks, no truck class/body-type/ranking category combination had greater than 20 observations. Therefore it was concluded that there was not an adequately large data set available for establishing ranking-category specific 22 Three Class 2b entries were removed due to suspiciously high payloads (16, 13, and 5 tons). One Class 8b truck was also removed (1 ton) due to an incongruous text explanation ("none used"). 23 ------- payload distributions for Truck Classes 2b-7. In these cases payload data were aggregated across all ranking categories for each truck class/body-type combination. The larger population of Class 8 trucks in the 2011 data set allowed for a differentiation of payload distributions across ranking categories. Considering both available sample size and average payloads, the following unique truck class/body-type/SmartWay ranking category groupings were established. • Class 8a Dry Van Single body-types: differentiate LTL (9.9 tons average) and non-LTL (12.4 tons average) categories. No differentiation across categories for other body-types. • Class 8b Dry Van Single body-types: differentiate Heavy-bulk (24.1 tons), LTL/Moving/Package (15.0 tons), Tanker (24 tons), and all other categories (18.5 tons). • Class 8b Specialty body-types: differentiate Auto Carriers (16.2 tons), Heavy/Mixed (30.3 tons), Flatbed (21.6 tons), and all other categories (25.6 tons). • Class 8b Dry Van Double body-types: differentiate TL/Reefer/Mixed (27.7 tons) and all other categories (19.4 tons) • Class 8b Other body-types: differentiate Heavy/Flatbed/Mixed (27.4 tons) and all other categories (21.5 tons). Based on this data, Table 5 presents the payload averages, standard deviations, minimum and maximum values by truck class/body-type/and-or ranking category.23 Note that the average values and standard deviations presented below are not weighted by fleet size. 23 Given the lack of data on non-diesel heavy-duty vehicles, payload ranges are assumed to apply to all fuel types. 24 ------- Table 5.

The values above serve as the basis for the default payload ranges provided in the Truck Tool payload calculator. For most vehicle class/body-type/ranking category 26 ------- combinations,24 seven default ranges are offered for Partner selection: • Range 1: from 0 tons to (Average payload - 2 x standard deviation); • Range 2: from (Average payload - 2 x standard deviation) to (Average payload - 1 x standard deviation); • Ranges 3-5: evenly split in three sections, from (Average payload - 1 x standard deviation) to (Average payload + 1 x standard deviation); • Range 6: from (Average payload + 1 x standard deviation) to (Average payload + 2 x standard deviation); and, • Range 7: from (Average payload + 2 x standard deviation) to (Average payload + 3 x standard deviation). Once a particular range is selected, the payload calculator estimates the midpoint of the range in order to estimate class level average payloads. The estimated midpoint payload values for each body type are weighted by one of the four allocation methods specified by the user in the payload calculator: # miles, # trips, % operation, and # vehicles by body type. The weighted sum is then used as the class level average payload, which in turn is used directly in determining grams per ton-mile performance metrics for the fleet. Payload data based on bills of lading and entered directly into the payload calculator are validated using the same data described above (see Section 3.4). LTL and Package Fleet Payloads For most payload validations in the Tool, ranges are calculated by class and by body type as described above. LTL and package delivery payload validation ranges were recently updated, and are calculated simply on a truck class basis, as there is not enough LTL and Package Delivery Partner information to break payload out by body type. Therefore each body type in a class is validated using the same range, as shown in Table 6 below. 24 In a few instances, the calculated lower bound value for Range 2 was less than zero. In these cases the lower bound value for Range 2 was set to zero and the Payload Calculator indicates Range 1 as "N/A". 27 ------- Table 6.

The middle R3-R5 ranges extend from one standard deviation less than the average payload to one standard deviation greater than the average. The upper payload values for "R6" range from the payload average plus one standard deviation to the average plus 1.5 standard deviations. The range for "R7" extends above the "R6" maximum value. The maximum R7 range values are taken directly from the original R7 maximum values described above by class and by body type.25 Note: Starting with the 2015 Truck Tool fleets with a SmartWay Category designation of LTL must also provide estimates for the average weight per shipment and the average number of shipments per truck. These values will be used to help refine the payload validation ranges for Shippers using LTL carriers. Default Cargo Volumes26 The Truck Tool also provides a volume calculator to estimate the cubic feet associated with the common straight truck body types (classes 2b through 7) identified using the 2011 Partner dataset, as well as typical trailer, container, carrier, and tanker sizes, for combination trucks (classes 8a and b).27 Cargo volumes in cubic feet are relatively easy to estimate for many combination trucks. Per unit interior volume defaults are assumed for standard dry vans - no high cubes, reefers, etc.), and containers. Trailer calculations assume an 8' x 9' cross-section, and the exterior length less 1/2 foot. 20 and 40 foot container dimensions are referenced in many places, such as http://www. m ussonfreight. com/containers/containers, htm 1.28 Table 7 summarizes the default volumes assumed for a number of standard trailers, containers, tankers, and bulk carriers. Table 7. Default Average Cubic Feet (Class 8a - 8b trucks) Type Trailers Size 28ft 40ft 42ft 45ft 48ft 53ft Cubic Feet 1,980 2,844 2,988 3,204 3,420 3,780 25 For two body types under Class 7 trucks (Combination Flatbed and Combination Reefer), the original Range 7 max value is less than the new Range 6 max value. (R7 max is 6.45 and 6.61 respectively, while the new R6 max value for all class 7 body types is 6.914). Therefore, for just these two body types within Class 7, instead of using the original Range 5 max, we use the Range 5 max that would be calculated from the new table values. This is calculated as Avg + 2.5 x standard deviation, based on the table above (7.896 in this case). [Note it is Avg + 2.5 x standard deviation instead of Avg + 3 x standard deviation because of the 1.5 sigma rule for Range 6. Therefore the Range 5 max value is simply 1 standard deviation larger than the Range 6 max.] 26 The Truck Tool allows users to enter cargo volume in either cubic feet or TEUs, with one TEU assumed equal to 1,360 cubic feet - see http://www.dimensionsinfo.com/20ft-container-size/. 27 Default cargo volumes for Class 7 combination vehicles were not available, and were set equal to the average volume for Class 8 combination trucks in the 2010 SmartWay database. 28 53 foot containers are assumed to have interior dimensions of 52' 5" x 7' 8" x 7' 10" 29 ------- Type Containers Tankers Bulk Carriers Size 57ft 28x28 48x28 40x40 48x48 28x28x28 20ft 40ft 45ft29 48ft 53ft Small (3,000 gal) Medium (5,250 gal) Large (7,500 gal) Small (22'x8'1 0.25') Medium (32'x8'x1 1 ') Large (42'x8.5'x1 1 .5') Cubic Feet 4,068 3,960 4,824 5,688 6,840 5,940 1,159 2,347 3,031 3,454 3,148 401 702 1,003 1,804 2,816 4,106 Cargo volume capacity data is often not readily available for straight trucks, however. Such trucks are highly variable in their configuration and when volume estimates are found, the data often do not permit cross-referencing with vehicle class. Most highway infrastructure and operating agencies, including enforcement, are concerned about weight (e.g., pavement and structure damage), but not cubic capacity. The operating agencies are also concerned about maximum dimensions, of length, height and width (for, respectively, turning radii, vertical clearance, and lane width) but the shape of the box and its relation to the truck superstructure, not these maximums, dictates cubic capacity. Little public research on the cubic capacity of the box has been done, and thus little information is published. A relatively small number of volume estimates were compiled from the 2011 Partner data (218 unique observations for truck class/body-type combinations). Of these observations 13 were identified as outliers and removed from the data set (11 observations of less than 100 cu ft; one Class 3 truck at 1,360 cu ft; and one Class 2b truck at 3,600 cu ft). Given the overall "thinness" of the dataset, those truck class/body- type combinations with three or more observations were used to estimate average cargo volumes. The following truck class/body-type combinations had fewer than three observations in the Partner dataset. • Class 2b Flatbed • Class 3 Other • Class 4 Flatbed, Step Van, Other • Class 6 Flatbed, Walk-In Van 29 45 and 48 foot container references from http://www.shippingcontainers24.com/dimensions/45-foot/. and http://www.containertech.com/container-sales/48ft-high-cube-container-domestic/ 30 ------- • Class 7 Flatbed, Tanker • Class 8a Beverage For these remaining truck class/body-type combinations available information was compiled as it relates to cargo volume capacity for the common straight truck body types. Without a comprehensive data source, such as the Partner data, other strategies needed to be employed to develop examples, or ranges, of volume capacity for the remaining body type/truck class combinations of interest. A literature review and vendor interviews were performed to determine appropriate values for cargo volume capacity. The first step in the literature review involved preparing a list of vendors responsible for designing, manufacturing, or operating all the different truck types identified. Cubic capacity is also dependent upon a variety of factors and is not uniform for even the same make and model, as many truck manufactures will design to specifications based on a client's unique needs for their cargo. For example, a client may request a manufacturer to design a truck interior to best accommodate the delivery of a certain size of parcel, and install shelving or otherwise compartmentalize to that end. Consideration was given to these factors during the review. The literature review encompassed Internet searches of vendors of the truck types described above. Sources explored included truck manufacturers, dealers, and fleet lessors of vehicles such as Budget/U-haul/Enterprise/Ryder/E-Dart). Additionally, validation searches were performed on websites outlining current truck sales to help identify the appropriate size/class of the vehicles and applicable specifications. The following information was collected from these searches for over 40 different vehicles currently available on the market: • Length, width, height of the cargo hold • Reported cargo space (cubic feet) • Gross Vehicle Weight • Payload • Manufacturer • Make/Model • Reference website Outreach to key stakeholders in the commercial vehicle industry was also performed to further validate the information collected from the literature and resource review. Contact was made with representatives from Volvo Trucks North America; the American Transportation Research Institute (ATRI); the Commercial Vehicle Safety Alliance (CVSA); the Truck Manufacturers Association (TMA); Federal Highway Administration (FHWA) Truck Size and Weight; and a wide variety of trucking manufactures and other vendors. 31 ------- The results of this review are combined with the averages from the Partner data and are provided in Table 8 below for straight trucks, classes 2b through 7. In those instances where multiple vehicle models were identified for a given body type/vehicle class combination, simple averages were calculated across models. Table 8.

The weighted sum is then used as the class level average cargo volume, which in turn is used directly in determining grams per volume-mile performance metrics for the fleet.

Many of these checks simply confirm the presence of required data (e.g., total miles for each truck class selected), or the accuracy of logical relationships (e.g., revenue miles <= total 33 ------- miles). The list of these basic checks is provided below. Partners will not be able to finalize their fleet files until all associated errors have been resolved. Also note that there is an implicit validation check on all numeric fields because the system will not accept any non-numeric characters (including minus signs) within these fields. Table 9. Basic Range and Logical Checks - Conditions Resulting in Error or Warning Messages Contact Information Fleet Description Fleet Description Fleet Description Fleet Description Fleet Description Fleet Description Fleet Description Fleet Description Fleet Description General Information General Information General Information General Information Activity Information Activity Information Activity Information Activity Information Activity User must enter at least two distinct contacts User must include a Partner Name. If entered, SCACs must be between 2 and 4 characters in length, and at least one character must be a letter. Multiple SCACs must be separated by commas.

User must indicate operational control over at least 95% of the fleet. (If Partner does not have at least 95% operational control, Truck Tool may not be used for the fleet.) The Operation Category totals must add up to 100%. The Body Type totals must add up to 100%. Warnings are issued for any of the following Operation Type/Body Type combinations. NOTE: This validation will only be invoked if there is a single selection made for either Operation or Body Type - otherwise combinations can't be determined with certainty. LTL/Chassis; LTL/Moving; LTL/Heavy; LTL/Specialized; Dray/Flatbed; Dray/Moving; Dray/Utility; Package/Flatbed; Package/Chassis; Package/Heavy; Package/Auto; Package/Moving; Package/Utility; Package/Specialized. User must designate the operations split between U.S. and Canadian operations. User must designate the Short-haul vs. Long-haul split. User must select at least one fuel type. User must designate the percentage of truckloads that utilize 100% of available cargo capacity. All fields are required, so no field can be left blank. (If appropriate, a zero can be placed in certain fields.) For all numeric fields except Empty Miles, Biofuel gallons, and Idle Hours, the value must be greater than zero. (An explanation must be provided for zero Empty Miles and idle hours). For mileage and gallons fields, enter exact rather than rounded values, (warning) For Revenue Miles, the amount cannot exceed the number of Total Miles Driven. For Revenue Miles, if the Data Source Detail "Equal to total miles" is selected on the 34 ------- Information Activity Information Activity Information Activity Information Activity Information Activity Information Activity Information Activity Information Activity Information Activity Information Activity Information Activity Information Activity Information Activity Information Model Year & Class Model Year & Class PM Reduction PM Reduction PM Reduction Payload & Volume Calculators Payload & Volume Data Sources screen, the amount must equal the Total Miles Driven. For Revenue Miles, if the Data Source Detail "Total miles less empty miles" is selected on the Data Sources screen, the amount must equal the Total Miles Driven minus Empty Miles Driven. For Empty Miles, the amount must be less than the number of Total Miles. For Empty Miles, if the Data Source Detail "Total miles less revenue miles " is selected on the Data Sources screen, the amount must equal the Total Miles Driven minus Revenue Miles Driven. On the Biofuel Blend Worksheet, the total gallons of biofuel cannot exceed the amount entered for Total Fuel on the Activity Information screen. For Average used cargo volume, the value cannot exceed 100%. For Average Used Cargo Volume Percent, the value must be less than 100% if user indicated that the fleet is 100% Less-Than-Truckload (LTL). (By definition, LTL fleets cannot have 100% average used cargo volume.) The implicit commodity density derived from the payload, volume, and average used cargo volume inputs must be between 0.001 and 0.65 tons/cubic foot.30 For Idle Hours, the value cannot exceed 8,760. For Idle Hours, values significantly outside the expected range must be explained. If company no idle policy is specified under on the Data Sources screen, then a warning is displayed if idle hours/yr are > 200. MPG must be greater than zero. MPG that is significantly outside the expected range for the given truck class (based on a lookup table) must be explained. Reefer fuel inputs for each fuel type must be less than the total vehicle fuel volume input. Total truck count for each fleet cannot be zero. Total truck counts for each selected truck class (those with a check mark) cannot be zero. The number of trucks using any particular PM reduction strategy cannot be greater than the number of trucks for the given class and model year. The sum of the trucks using either DOC or Particulate Matter Traps cannot be greater than the number of trucks for the given class and model year. If user indicates that the company uses PM reduction equipment, there must be at least one truck included on the PM Reduction sub-tab. User must provide a preferred allocation method for the information entered on the calculators. The sum of the total miles or total trucks entered in the calculator must equal the 30 The upper bound density range was based on gold (~0.6 tons/cubic foot) and the lower bound range on potato chips (-0.003 tons/cubic foot) - see http://www.aqua-calc.com/paqe/density-table/substance/Snacks-coma- and-blank-potato-blank-chips-coma-and-blank-white-coma-and-blank-restructured-coma-and-blank- baked. 35 ------- Calculators Payload & Volume Calculators Payload & Volume Calculators Payload & Volume Calculators Payload & Volume Calculators Payload & Volume Calculators Payload & Volume Calculators Payload & Volume Calculators Payload & Volume Calculators Payload & Volume Calculators Payload & Volume Calculators Payload & Volume Calculators Payload & Volume Calculators number entered on the Activity Information screen. The calculated average cannot be equal to zero. For percentages, the total must equal 100%. For each body type for which some information has been entered, all of the visible field must be completed (including the explanation field if shown). Zero is not a valid value for any payload or volume. Values that are significantly outside the expected range for the given body type and class must be explained. The body types indicated in the Volume Calculator must agree with those used in the Payload Calculator. Ensure consistency between body-type selections in the Fleet Description section with those from the Payload and Volume Calculators. For example, if 100% is specified for Dry Van under Fleet Description, only Dry Vans (single, double, triple) may be selected within the calculators. See Table 9. If "# of Vehicles in this class" is selected for both the Payload and Volume calculators for a given truck class, the number of trucks entered into each calculator must agree. If "# of Vehicles in this class" is selected for either the Payload or Volume calculator, the number of body-types selected cannot exceed the number of vehicles specified. If "# of miles in this class" is selected for both the Payload and Volume calculators for a given truck class, the number of miles entered into each calculator must agree. If "# of Trips done by this class" is selected for both the Payload and Volume calculators for a given truck class, the number of trips entered into each calculator must agree. Ensure consistency between the body-type selections in the Class 8a/b payload calculator and the corresponding Volume calculator - i.e., issue warnings for any type of dry van, reefer or beverage selected in the payload calculator but no Trailers specified in volume calculator. Validations have been added to the Truck Tool to ensure the selections in the 8a/8b volume calculator are consistent with the selections in the payload calculator for those classes: RED errors (must address): - If the user has values for 8a body type "Beverage" or "Dry Van - Single" in the Payload calculator, they must have a value in the "Trailed section of the volume calculator. - If the user has values for 8b body type "Dry Van - Single" or "Dry Van - Double" or "Dry Van - Triple" in the Payload calculator, they must have a value in the "Trailer" section of the volume calculator. YELLOW warnings (comments/changes not mandatory): - If the user has values for 8a body type "Flatbed" or "Combination Flatbed" in the Payload calculator, they must have a "Flatbed" checkbox checked in the "Trailer" section of the volume calculator. 36 ------- - If the user has values for 8a body type "Single-Axle Van" or "Dry Van - Single" in the Payload calculator, they must have a "Box" checkbox checked in the "Trailer" section of the volume calculator. - If the user has values for 8a body type "Beverage" in the Payload calculator, they must have a "Box" or "Reefer" checkbox checked in the "Trailer" section of the volume calculator. - If the user has values for 8a body type "Tanker" in the Payload calculator, they must have a value in the "Tanker" section of the volume calculator. - If the user has values for 8a body type "Other (straight truck)" or "Other (combo)" in the Payload calculator, they must have a value in the "Bulk", "Auto Carrier", or "Other" section of the volume calculator. - If the user has values for 8b body type "Dry Van - Single" or "Dry Van - Double" or "Dry Van - Triple" in the Payload calculator, they must have a "Box" checkbox checked in the "Trailer" section of the volume calculator. - If the user has values for 8b body type "Combination Reefer" in the Payload calculator, they must have a "Reefer" checkbox checked in the "Trailer" section of the volume calculator. - If the user has values for 8b body type "Combination Flatbed" in the Payload calculator, they must have a "Flatbed" checkbox checked in the "Trailer" section of the volume calculator. - If the user has values for 8b body type "Combination Tanker" in the Payload calculator, they must have a value in the "Tanker" section of the volume calculator. - If the user has values for 8b body type "Chassis" in the Payload calculator, they must have a value in the "Chassis" section of the volume calculator. - If the user has values for 8b body type "Specialty" or "Other" in the Payload calculator, they must have a value in the "Bulk", "Auto Carrier", or "Other" section of the volume calculator. As noted in Table 9 above, a warning is issued if an inconsistency is identified between body-types specified within the Fleet Description Section and those within the Payload/Volume Calculators. Warning conditions (associated with 100% body-type entries under Fleet Description) are presented in Table 10 below. 37 ------- Table 10.

Validation checks serve three purposes to this end. First, unusually high or low values can be identified and flagged for the user's attention before finalizing inputs. For example, a user may misplace a decimal, inadvertently add an extra zero, or utilize the wrong units (e.g. reporting pounds instead of tons for payload) upon data entry. By comparing these data entries to reliable industry averages and distributions, these values can be flagged allowing users to quickly correct such errors. Second, under certain circumstances Partners may operate their fleets under atypical conditions, resulting in extreme (outlier) data values. For example, permitted heavy- haul operations may routinely exceed industry-average payload values by 10 or more tons. By flagging such data entries Partners have the opportunity to provide additional information regarding their unique operating conditions through use of the Truck Tool comment fields. Finally, independent criteria can be established to ensure that data inputs are never allowed to exceed certain physically-constrained absolute limits. For example, a truck cannot exceed roughly 500,000 miles per year, even with dual drivers and minimal maintenance time, simply due to the available hours per year and highway speed limits. Data values above these absolute maximum levels are not allowed by the Truck Tool, and users are required to modify the associated inputs before proceeding. The following presents the updates to the Truck Tool validation ranges for all parameters but payload and volume, which are discussed above. Validation ranges are of three types: 1. "Yellow" values indicating that the input or derived performance value is notably lower/higher than the expected value. Partners may enter an explanation backing up such entries, but this is not mandatory. 2. "Red" values indicating that the input or derived performance value differs greatly from the expected value. In this case the partner must enter text explaining why this value is accurate. Once entered, the value will change from "Red" to "Orange" on the data entry screen. 3. "Absolute errors" exceed values deemed physically possible and must be changed in order to be accepted by the tool. Reefer Fuel Validation 507 diesel fleets designated as "Reefer" for the 2013 calendar year were evaluated to determine the distribution of the fraction of reefer fuel consumption to total fuel consumption. Ten of these observations were dropped from the analysis data set, having either 0 gallons of reefer fuel entered, or reefer fuel consumption was greater than total consumption.31 As shown in Figure 3 below, the distribution for the remaining reefer fleets was highly skewed toward low fractions (reefer consumption / total 31 Additional validation rules have been implemented, so such data entries are no longer possible. 39 ------- consumption). For this reason EPA simply used 5% increments for the Range 1 and 2 validation values, but used the average plus 1 to 2 standard deviations for Range 4, and > 2 standard deviations for Range 5. The resulting values are shown in Table 11 below. Figure 3 # Obervations vs Fraction of Fuel used by Reefers 200 150 100 50 0.2 0.4 0.6 0.8 Table 11.

If the percentage designated as "Reefer" in the Body Types section of the Truck Tool is less than 100%, then the fuel validation ranges are scaled downward by the reported percentage. Data Processing Except as noted above, the validation range recommendations are based upon a distributional analysis performed on the 2011 Truck Partner input and performance 40 ------- data. Fleet level data was input into SAS and grouped by truck class, bin category, and fuel type combinations. If a particular combination had less than 20 fleets, it was aggregated to the next "higher" level until at least 20 fleets were included. This process resulted in 26 groupings, as shown in Table 12. Note these groupings are mutually exclusive - e.g. "Class 6_Mixed" (Group 6) includes all Class 6 vehicles with the exception of TL/Dry Van, LTL/Dry Van, Moving, Package, (Groups 5, 7, 8, and 9).

Each fleet was treated equally in the distributional assessment, independent of the number of vehicles in the fleet. Histograms presenting the distributions for each truck fleet grouping/metric combination are available electronically from SmartWay. For groupings with large numbers of fleets (e.g., Class 8b diesel TL/Dry Van, Refrigerated, and Mixed), the data for miles per vehicle and MPG appear normally distributed. Examples for Class 8b TL/Dry Van Diesel fleets are shown in Figures 4 and 5. 44 ------- Figure 4.

Based on this preliminary assessment, red and yellow flag areas were defined for each fleet group/metric combination as shown in Table 15. 32 As such, a yellow warning is issued for any biodiesel blend > 20%, with no red warning. 46 ------- Table 15.

AA Values selected in consultation with SmartWay support staff. For six of the metrics,33 yellow flag criteria were set at ± 1.5 times the standard deviation (StD), and the red flag criteria at ± 2.0 times the standard deviation of the distribution for each truck fleet grouping. In most cases these criteria result in roughly 10-15% of the values for these metrics being flagged as either red or yellow for partner attention (although the flag rates associated with % Revenue and % Empty Miles is substantially higher). Selecting cutoffs at this level of stringency is intended to identify likely input errors without unduly burdening the large majority of Truck Tool users with unnecessary data checks and text explanations. Tables 16-21 present the actual yellow and red flag values for each fleet group/metric combination, given the decision criteria presented in Table 15. Tables 22-27 present the number of observations that would be flagged with yellow and red warnings for these combinations. 33 Standard deviations are only used on the low end to determine red/yellow cutoffs for the % Average Used Cargo Volume metric, due to a number of carriers utilizing 100% of available space. Upper end cutoffs are based on expert judgment for LTL categories. 47 ------- Table 16.

Cutoffs for absolute errors are intended to prevent users from inadvertently entering data with incorrect units and typos. For this reason we have defined absolute errors to ensure an adequate "safety" interval between the highest values observed in the cleaned (no outlier) dataset. The recommended values for absolute errors and their associated justifications are discussed below for each metric. Annual Miles per Vehicle The maximum number of miles a vehicle can accumulate in a year are constrained by truck highway speed limits (typically 65 mph or less) and the number of hours in a 59 ------- year.35 Excluding engine down-time associated with maintenance and repairs, the absolute maximum annual mileage possible for a truck is estimated to be ~500,000 miles per year. This estimate is more than twice the highest observed value of 228,151 miles per year (for Class 8b TL/Dry Van diesels). Therefore 500,000 miles per year value is set as the absolute maximum for all vehicle classes. Values greater than 0 and less than 500,000 are permissible.

Hybrids are subject to separate validation ranges for the 2015 version of the Truck Tool as discussed below. The maximum value for non-hybrid Class 3 diesel trucks was 14.4 mpg. 60 ------- [Note: Unlike the other parameters discussed above, miles per gallon values are derived from other inputs (total miles and gallons). Therefore any changes to address absolute limits on MPG (as well as red and yellow warnings) must be handled through updates to one or both of these primary inputs.] As seen from the above table, fuel efficiency estimates can be very low (<1.0) and for this reason no absolute lower bound is used for miles per gallon. To establish absolute upper bounds for miles per gallon estimates the results from the PERE modeling analysis previously developed for the 2010 Truck Model were used. Background on the PERE modeling exercise is provided in Appendix E. Absolute maximum miles per gallon estimates were developed for conventional diesel trucks using the PERE model, and are shown in Table 29 by truck class. Table 29. Maximum Diesel Miles per Gallon Estimates (PERE Model Basis) Class 2b 3 4 5 6 7 8a 8b Maximum MPG 25.0 23.3 20.2 18.7 18.0 14.5 11.2 11.2 Note that the maximum MPG estimates obtained from the PERE model are all substantially higher than the maximum value observed for non-hybrid diesel trucks in the 2011 Truck Tool data. Non-Diesel MPG The 2011 data submissions from SmartWay Truck partners did not include enough information on non-diesel trucks in order to develop a robust distribution of mpg values specific to non-diesels for validation purposes. Accordingly, engineering judgment was used to adjust the diesel mpg values for other fuel types, accounting for general, relative vehicle and/or fuel efficiency differences. First, a ratio was developed for adjusting diesel mpg values to comparable gasoline mpg values, based upon simulated modeling performed by Argonne National Laboratory.37 The Argonne data for gas and diesel trucks was based on PSAT simulations of a typical pickup in the Class 2b or Class 3 range. The fuel consumption was reported for the same truck equipped with 37 Delorme, A. et. al., Impact of Advanced Technologies on Medium-Duty Trucks Fuel Efficiency, Argonne National Laboratory, 2010-01-1929. 61 ------- both gasoline and diesel engines over the various EPA emissions and fuel economy driving cycles. Using this data, a combined fuel economy was calculated using the method from EPA's pre-2008 combined 2-cycle fuel economy using the FTP and Highway cycles as given in 40 CFR Part 600. This method uses a weighted harmonic average of the two values, with the FTP weighted at 55% and the Highway weighted at 45%. The difference in the calculated combined fuel economies for the gas- and diesel- powered model results showed that the diesel had a 25.9% greater fuel economy than gasoline. These results are a direct volumetric comparison rather than in terms of gasoline-equivalent gallons. As such, the diesel mpg values shown in Table 28 above can be divided by 1.259 to obtain comparable mpg ranges for gasoline vehicles. Since CNG vehicle fuel consumption is reported in terms of gasoline-equivalent gallons, the mpg validation ranges for CNG vehicles can be set equal to those for comparable gasoline vehicles. Validation ranges for LPG and LNG vehicles can be developed from the gasoline ranges, dividing the gasoline values by the appropriate gasoline gallon-equivalent factor for these fuels (1.35 for LPG and 1.52 for LNG),38 thereby adjusting mpg values for volumetric energy density. Table 30 presents the corresponding upper bound MPG values for non-diesel vehicles by truck class. Table 30.

The details of the modeling are presented in Appendix E. However, the in-use fuel economy of hybrid vehicles is highly dependent upon drive cycle. Specifically the expected hybrid truck fuel economy will vary depending upon the 38 https://www.afdc.energy.gov/afdc/prep/popups/gges.html 62 ------- relative fraction of highway versus urban driving. Therefore the MPG ranges used for validation of hybrid fuel economy are calculated using the following steps.

The Low Red Gallon/Mile value is therefore 0.2641 x 0.40 + 0.1759 x 0.60 = 0.2112 Step 2: Convert the weighted gallon per mile values back to MPG Example: 0.2112 gal/mi = 4.74 MPG Step 3: Use these final, weighted, converted MPG values for validation. Electric Truck Efficiency Mi/kWhr estimates for battery electric trucks were developed based on available data sources and engineering judgment. The average value for Class 2b trucks was assumed to equal the mi/kWhr value estimates for large SUVs in EPA's MARKAL model 64 ------- (3.01). The values for Class 4 and 6 electric trucks (1.43 and 1.00 respectively) were taken from Calstart's E-Truck Task Force Business Case Calculator. Values for Class 3 and 5 trucks were based on simple averages of the Class 2b, 4, and 6 values. Given the lack of available data for the heavier truck classes, values for Class 7 (0.75), Class 8a (0.5) and Class 8b (0.4) were based on engineering judgment. Once average mi/kWhr estimates were derived, "red" and "yellow" ranges were established based on simple multiplicative factors applied to the averages - Low red from 0 to 0.5 x average; low yellow from 0.5 x average to 0.75 x average; high yellow from 1.25 x average to 1.5 x average; and high red from 1.5 x average to 10 x average (absolute max). Percent Revenue Miles Revenue miles were frequently equal to total miles in the dataset. Accordingly, no absolute upper (or lower) bound was set for this field, beyond requiring all values to be >0and < 100. Percent Empty Miles Empty miles were occasionally equal to 0 in the dataset. Accordingly, no absolute lower (or upper) bound was set for this field, beyond requiring all values to be > 0 and < 100. Percent Biodiesel While the maximum observed blend level for biodiesel was 20 percent, B100 use is possible. Therefore no absolute upper (or lower) bound was set for this field, beyond requiring all values to be > 0 and < 100.

One type of error results from data being entered in pounds instead of short tons, resulting in overestimates by a factor of 2,000. Such errors should be easy to prevent using a reasonable upper bound ton level. Another possible source of error could be reporting metric or long tons instead of short tons, although detecting these errors will be extremely difficult, due to the small difference in units (roughly 10 percent difference). Finally, note that standard payload limitations can be waived by obtaining permits for heavy loads, or by avoiding over-the-road operation.40 Accordingly, the absolute upper bound payload levels were set equal to 3 times the maximum observed values shown in Table 31. However, no absolute lower-bound payload value was set, to allow for light package and specialty deliveries. Therefore the only low end constraint is the requirement that payloads be > 0. Average Volume The maximum and minimum observed volumes from the dataset (prior to cleaning) are presented in Table 32. 40 One Smart Way Truck Partner indicated unusually high payloads for their Class 2b truck fleet, but noted they only use their trucks in terminal operations. 66 ------- Table 32.

However, no absolute lower-bound volume value was set, to allow for small package and specialty deliveries. Therefore the only low end constraint is the requirement that volumes be > 0. Average Used Cargo Volume % Average used cargo volume % was frequently equal to 100 in the dataset. Accordingly, no upper bound was set for this field. In addition, no absolute lower-bound was set for 41 One Class 6 LTL fleet with an extreme outlier volume of 12,000 cubic feet was dropped for the purposes of this analysis. 67 ------- utilization either, to allow for small package and LTL/specialty deliveries. The only requirement is that all values be > 0 and < 100. The new Truck Tool adds a new Data Source option for Dray carriers allows them to select an industry average used cargo volume % factor, since these carriers may not know how their containers are loaded. To calculate the industry average value the following calculation steps were performed: 1) All truck carriers with a Dray Operation tag were identified from the 2012 Truck Tool submittals -109 dray carriers with 20,774 trucks. 75.9% of these trucks had a Chassis Body Type tag, 23.2% had a Dry Van tag, and 0.9% had a Mixed tag. No other body type tags were reported for dray carriers. Essentially all of these trucks were Class 8b diesels. 2) All non-dray carriers with Chassis, Dry Van, and Mixed Body Type tags were selected, and the average used cargo volume % was calculated for Body Type tag, weighted by the number of trucks. (This approach assumes that none of the average used cargo volume % values reported for Dray carriers were reliable, regardless of their Data Source selection.) There were 229,349 trucks in this data set. The weighted average used cargo volume % values for non-dray carriers were as follows. Chassis 90.5% Dry Van 84.8% Mixed 85.4% 3) The weighted average used cargo volume % values from Step 2 were combined with the body type percentage distribution from Step 1 to obtain a single, industry average for used cargo volume % value for use by Dray carriers of 89.13%. This estimate applies for all truck classes and fuel types, as the data set is very thin for anything other than class 8b diesels. Note that this value will only be used if a Dray Carrier selects the "Industry Average" button on the Activity screen or the default selection on the Data Source screen. Also note that the default option is only available to carriers that specified a non-zero Dray operations percentage in the Fleet Description section - otherwise the Industry Average button will not appear. Percent Urban/Highway Miles There is no clear distributional pattern associated with these data fields, with values frequently ranging from 0 to 100. Therefore no lower or upper bound values are set. Average Annual Idle Hours per Truck The maximum and minimum observed idle hours from the dataset (prior to cleaning) are presented in Table 33. 68 ------- Table 33.

Available performance metrics include: • Grams per mile • Grams per Payload Ton-Mile • Grams per Thousand Cubic Foot-Miles • Grams per Thousand Utilized Cubic Foot-Miles The Internal Metrics report within the Truck Tool presents the results of 36 calculations (4x4x3 = 48), which represent the following four calculations for each of the three pollutants (C02, NOx, PMio and PM2.s) and for each of three different mileage types (total, payload, and loaded). Note that all capitalized fields represent fields in the user interface: 1. g/mile: £ E / M where E = Emissions, M = Miles Driven 2. g/avg payload ton-mile: X E / (M x AP) where E = Emissions, M = Miles Driven, AP = Average Payload 3. g/avg cubic foot volume: X E / (M x ACV) where E = Emissions, M = Miles Driven, ACV = Average Cargo Volume 4. g/avg utilized cubic foot: £ E / (M x ACV) / CU where E = Emissions, M = Miles Driven, ACV = Average Cargo Volume, CU = % Cube Utilization For all four calculations: Emissions = grams of pollutant (as specified above) Miles Driven = Total Miles, Payload Miles, or Loaded Miles (Total Miles minus Empty Miles) As shown in the equations above, summations are performed for the different metrics. Each of the metrics is automatically aggregated across model years (for NOx and PM) for all reporting purposes. Additional aggregation may be reported across truck classes, fuel types, divisions, and at the company level, as specified by the user. 70 ------- Appendix A: MOVES2014a-based NOx/PIVh.s Emission

The model calculates second-by-second fuel consumption for user- defined drive cycles based on a physical model. The model takes a number of user- specified parameters, along with some of its own defaults, to perform these calculations for a variety of vehicle and powertrain types. The assumptions and data sources for the model inputs that were used are presented below. The defaults for some parameters, such as hybrid regeneration efficiency and hybrid battery efficiency, were assumed to remain unchanged when scaling from light-duty to heavy-duty vehicles. Many vehicle parameters, such as road load and transmission data, were used from work already done with the PERE model for the SmartWay program. Many of the parameters for that previous work were taken from findings of internet searches for specifications of various trucks in new "as-delivered" condition, prior to the addition of various vocational or cargo equipment installations that would increase drag and vehicle weight. To establish the test weights for each truck class in this modeling effort, the original estimate of minimum weight was averaged with the maximum possible weight for each truck class. This was done with the intent of modeling an average or medium payload for each truck class. An important source of information was an EPA draft document discussing the use of the PERE model by Nam and Gianelli42. This document contained equations that could be used for estimates of some of the input parameters, along with information describing the use of the model. The two foremost inputs to the model include the vehicle weight and engine size. Vehicle empty weights and engine sizes were taken from manufacturer supplied truck specifications where possible. For example, Ford published a .pdf file titled F- 250/F-350/F-450/F-550 Specifications43 that contains base curb weights and engine sizes for some of their offerings in the light and medium duty market. Another useful source of manufacturer data was in the Kenworth T170/T270/T370 Body Builders Manual44. The T170-T370 range consists of medium duty trucks that can be delivered with a cab-only chassis. The manual describes all of the dimensions relevant to the builder of a body or cargo area on the rear of the chassis. As such, it includes curb weights, length and width dimensions, and gross vehicle weight ratings that were instrumental in creating many of the inputs for the Class 5, 6, and 7 fuel economy models. Where specifications of multiple trucks in a class were found, values were taken that would result in maximum fuel economy unless they seemed noticeably atypical of in-use vehicles. Variations in weight and engine size over the 42 Nam, Edward and Gianelli, Robert, Fuel Consumption Modeling of Conventional and Advanced Technology Vehicles in the Physical Emission Rate Estimator (PERE).

Retrieved from http://www.kenworth.com/brochures/2009_Hybrid_Body_Builders_Manual.pdf E-l ------- ranges found in literature did not have as large an effect on fuel economy as some of the other inputs to the PERE model. For hybrid modeling, the engine size reduction due to hybridization ranged from 1 liter for the Class 2b and 3 trucks, up to 4 liters for the Class 8 trucks. This range was chosen based on the nature of hybrid trucks currently available on the market. Class 2 hybrid trucks on the market typically have very little engine downsizing from hybridization, however larger trucks were found to have more engine downsizing. The number of transmission gears in each truck class was also based on specifications found on manufacturers' web sites, but there is a wide range of the number of gears in the different available transmissions. While it is very likely that the most efficient setup for Class 2b through 4 would be a 6 speed manual transmission, there are a variety of options for Classes 5 through 8. It is also typical for a modern Class 8 truck to have 10 gears, so the model input for Class 6 was taken to be 8 as a representation of typical trucks in that class, and all trucks were modeled with manual transmissions. The PERE model also requires shift speeds as an input to the model, and examples of these were not found in literature or internet searches. ERG has previously logged on-road data from Class 8 trucks with 10- speed manual transmissions, and this data was analyzed briefly to create an estimate of typical upshift speeds for this type of truck. Using this speed/gear curve, two other curves were created by scaling for the 6 and 8 speed trucks modeled in the study. Unfortunately, the shift speed chart has a very strong effect on the model's predicted fuel economy, but using carefully scaled shift point curves hopefully mitigated this source of error. The hybrid trucks were modeled with exactly the same transmissions as the conventional trucks. The model did not readily include a provision for changing the transmission characteristics when changing from conventional to hybrid powertrains. All transmission parameters were kept the same when making this change with the intent of ensuring the resulting fuel economy effects were only due to hybridization, not due to transmission effects. There were three other values regarding the driveline that were input for this study. The engine efficiency was taken to be 40% over the cycle. The maximum engine speeds and highway cruise speeds were adjusted together as well, to account for the larger displacement heavy duty engines turning more slowly than typical Class 2b truck engines. The effects of the engine speed parameters on fuel economy were fairly small. The road load estimation required assumptions and calculations as road load curves are not generally a part of manufacturers' literature. The method of road load calculation used for this PERE modeling was based on the coefficient of rolling resistance (Cp), the aerodynamic drag coefficient (Cd), and the vehicle frontal area (Ap) in a physical equation of the truck's road load, given in Equation 1 from Nam and Gianelli (2005). Coefficients of drag were based on values in literature, such as manufacturers' specifications for Class 2b and in a report publication by Argonne E-2 ------- National Laboratory45. Values for Cd ranged from .45 for the Class 2b and the smaller medium duty trucks, to .5 for the class 8 long-haul trucks. The heavier medium duty trucks were assumed to have a Cd of .55 as they were assumed to be vocational trucks with less streamlined aerodynamics. Frontal area was taken from manufacturer specifications where available. As given in Nam and Gianelli, the product of truck height and width was multiplied by a factor of 0.93 to get an estimate of effective AF. Engineering judgment was applied to the dimensions found in literature to ensure a representative increase in frontal area from the smaller to larger trucks. The rolling resistance values were estimated using the trends observed by both Nam and Gianelli (2005) along with Delorme Karbowski, and Sharer (2009), ranging from 0.01 for the light and medium duty trucks, down to 0.008 for the class 8 trucks. The final input to the PERE model was the driving cycle. In order to get a representative range of fuel economy benefit, two drive cycles were modeled. The first was the Heavy-Duty Urban Dynamometer Driving Schedule (HDUDDS), and the second was the EPA Highway Fuel Economy Test (HwFET). The HDUDDS can be thought of as a city-type cycle with frequent stops and starts. The HwFET simulates rural driving with varying speeds but no stops. Even though the HwFET is designed only for light duty vehicles, it was still used as it was the best representation available for in-use highway driving. The key values used as the inputs for the PERE model fuel economy calculations are given by truck class in Table E-1. Table E-1.

This variable represents the amount of power demand during acceleration that is required to 45 Delorme, A., Karbowski, D., and Sharer, P. Evaluation of Fuel Consumption Potential of Medium and Heavy Duty Vehicles through Modeling and Simulation. Argonne National Laboratory, DEPS-BEES-001, October 2009. E-2 ------- cause the engine to start up to assist the electric motor. The user must adjust this value such that the amount of energy taken from the battery is approximately equal to the amount of energy charged back into the battery during regenerative braking. If this is not done, the fuel economy will be misrepresented due to the battery ending up with a different state of charge at the end of the cycle compared to the beginning of the cycle. For the HwFET cycle in the lower truck classes, there were not enough deceleration events charge the battery back to its initial charge level, even with the hybrid threshold variable at its minimum value. This meant that the battery was ending at a lower level of charge at the end of the cycle than the beginning, which has the effect of overestimating the trucks actual fuel economy. For this reason, ERG added an extra calculation to the model in order to account for the net change in battery power. This calculation used the various efficiencies of the hybrid system to estimate the fuel required to make up the change in battery charge over the cycle, and add that number to the modeled fuel consumption. This calculation was needed for the trucks in Classes 2b through 5 E-4 ------- |
