I. Overview
Background and Purpose
The Mobile Source Observation Database (MSOD) is a relational database being
developed by the Assessment and Standards Division (ASD) of the United States Environmental
Protection Agency (U.S. EPA or Agency) Office of Transportation and Air Quality (OTAQ,
formerly the Office of Mobile Sources). The database supercedes a previous database that was
called "Mobile Source Emission Factor Database." Currently, the database stores general
purpose emission factor data collected since 1982 and other activity and emission test programs
that was gathered by U.S. EPA and from other testing facilities that were designed for more
specific purposes. The data contained in the database was not gathered on a purely "random"
sample and for different research issues but the data is intended to be representative of in-use
vehicle emissions in the United States.
Considerable knowledge of vehicle emission testing and of relational database design and
query methods is required to make effective use of this database. It is not intended for the casual
or novice user. The database has been designed and documented using entity-relationship data
modeling methods.
The database itself is implemented as an Oracle database containing a set of
approximately 60 tables, supplemented by a larger number of small "translation" or "category"
tables which define and explain the legal values for some of its individual data items. All tables
will be exported upon request in standard database format (*.DBF) which is usable by a variety
of software and users. While ASD is interested in comments and questions regarding the
database, it can afford to provide only very limited support beyond this Guide to external users.
EPA has made considerable effort to assure the validity of the data in this database
through the development and use of quality assurance and control procedures. EPA is not
responsible for the validity of conclusions reached by others using this data. New records are
being added continuously to the data sample as they complete their review. EPA cannot
guarantee that all current, relevant data has been included in the database. Because additions and
changes are being made to the database on a continuous basis, it is recommended that those
using it regularly may wish to request an updated copy every year or so.
a. Mobile Source Observation Database (MSOD)
Design Features
This new relational design enables storage of any observation of a mobile source, which
can include emission tests (laboratory and in-use "field"), activity measurements, fuel, engine
and vehicle characteristics. Observations are results that were derived from (laboratory or in-use
"field") testing a mobile source. A "mobile source" is a term used to describe a wide variety of
vehicles, engines, and equipment that generate air pollution and that move, or can be moved,
from place to place. Mobile Sources can be separated into two main categories: "On-Road" and
'Non-Road." "On-Road" (also called "on-highway") sources include vehicles used on roads for
transportation of passengers or freight. "Non-road" (also called "nonroad") sources include
vehicles, engines, and equipment used for construction, agriculture, transportation, recreation,
and many other purposes. These two broad categories, on-road and nonroad sources can be
-------
further segregated by size, weight, use, and/or horsepower. MSOD was designed with the
following features:
• Design leads to client server-based database with an economy of tables and fields with most
data stored in only one place.
• Low cost to implement and maintain database design
• Easy to adapt for new data types and design resides within EPA
• Modern database design allows for it to be portable and compatible with other modern tools.
• Designed for broad scope to contain both vehicle and engine data (laboratory or field testing
including second-by-second data)
• Tables are easily linked together
• Easy to understand by using meaningful field names, documenting the legal values and
definitions that are explained in the database
• Contains "Meta" data on who conducted the test, statements of work, etc
• Contains information on driving schedules, diurnal temperature evaporative test cycles, etc.
• Contains information about fuels on either a generic (batch) or specific fuel analysis.
What are Results?
Observing mobile sources (vehicles and engines) will give different kinds of results. A
result can be grouped into specific areas called "entities" that contain "fields" or "attributes" with
similar characteristics might be observed. Some different kinds of results or entities are listed
below:
• Procurement
• Inspection
• Owner's Report
• Repair
• Tailpipe Emission Test
• Running Loss Emission Test
• Evaporative Emission Test
• In-Use or "Real World" Emission Test
• Engine Power MAP
• Engine Dynamometer Emission Test
• Tank Fuel Measurement
• Fuel Type Information
• Driving Schedules
• Etc.
Some of the result tables can be large and complex. These tables have been indexed to improve
their performance. All result tables have had their fields either coded or categorized (fields that
have translation tables) so that have their meaning or description are known.
-------
What is the CAUSE Relationship between RESULT?
A "cause" relationship between certain "results" represents the fact that some "results"
affect subsequent "results." Currently this occurs only in the PROCURE and REPAIR type
RESULT tables. The CAUSE is a foreign key (recursive relationship) back into RESULT table.
It identifies the most immediately preceding RESULT instance (e.g. a PROCURE or REPAIR on
this mobile source instance) that might affect the outcome of the present one. This feature
allows for a query into the database to see if different procurements of the same mobile source
have intervening repairs or previous testing conditions plus others that may not be comparable
for some purpose. For example, you can use the CAUSE attribute to distinguish post-repair
observations from pre-repair observations. A CAUSE = 0 means that there are no related results
or none.

-------
What is a "Replicate" RESULT?
A replicate RESULT represents a repeated observation of the same thing and is often
performed to investigate the repeatability of measurements. Replicates are stored in the MSOD
database and are found in the RESULT table under PREV_REP and NEXT_REP fields. These
fields link RESULTS together in a forward chain (NEXT_REP) and backward (PREV_REP).
The value "0" indicates the end of the PREV_REP and NEXT_REP chain. To eliminate
multiple replicates from query outcomes, the user will need to specify that PREV_REP = 0 or
NEXT_REP = 0 as a query selection criteria.
What is a "Composite" RESULT?
The MSOD database structure allows a group of RESULTS to be considered a RESULT
in its own right and are called "Composite RESULTS" or "RESULT Group." An example use
of this feature is that the component portions of the Supplemental Federal Test Procedure
(SFTP), which consists of multiple individual tests that are weighted together to give one
Composite RESULT. The RESULTGRP field in the RESULT table indicates or joins the
individual RESULTS to the Composite RESULT. A RESULTGRP = 0 indicates that the
RESULT is not part of the Composite RESULT.
Understanding Translation Tables or Legal Value Lists for Categorized Fields
The database has been documented in a platform-independent fashion that allows for greater
flexibility in its use on different database platforms and helps implement data quality by defining
all legal values of all categorized fields. Every categorized field, which includes most character-
type fields in the database, has a "translation table" not shown in the entity-relationship
diagrams. These "translation tables" contain:
• The table name is the same as the name of the field, truncated if necessary to meet a eight-
character limitation.
• The first column in the table is the same as name in field.
• The second column in the table is typically the field name number "Fieldname_N" which
expresses the category as a number so that it can be used in statistical programs (e.g. SPSS or
SAS).
• The third column in the table is typically the field name description "Fieldname_D" which
defines the category value.
Representation of Missing or "Null" Data
The current version of MSOD was upgraded to take advantage of "true" NULL for each
field in each table. Users should attach no meaning to data values that contain "Null." The
value simply means that the data for this field is not present in the record and can occur for many
reasons.
-------
What are MEASTYPEs?
The database design contains areas or tables that allow for the storage of data that are
only gathered occasionally and are not considered of central importance. These MEASTYPEs
are referred to as "Non-Core Measurements." By permitting, MEASTYPEs in the database
structure this allows for the following aspects: it avoids having to create additional columns for
data items that are only occasionally needed and it makes it easy to extend the database design to
accommodate new items. Tables that contain names like "xxxMEAS" and VEH_MISC are
examples containing such data.
b. MSOD Input Structure
Lab and field data must be formatted in specified data entry tables before the data can be
quality assured and loaded into MSOD. The conformity of the data to this format allows pre-
programmed computer software to check the data for it's conformity to MSOD data types and
categories for attributes (fields), range checking of numeric data, and the assurance of parent
child referential integrity. The input structures in general are relational data bases based on
result kinds found in the database and reflect the entities and attributes associated with them in
MSOD. Input data tables in general follow a naming convention that close to the table name
reflect its result kind's entities in MSOD, but ending with "_IN." The tables are in a *.DBF
database structure that allows for true NULLs. Most PC based database software (e.g. Microsoft
Access, DBASE, Visual FoxPro and Lotus Approach) are capable of reading and writing to this
format. All tables, fields, categories and attributes have legal naming convention and
definitions including measurement units that are directly from the MSOD design. Section III
gives the user a graphical picture plus table and field definitions on the most current input table
designs. An electronic copy of the input structures can be requested, please see section I(e)
below for further information.
c. Quality Control and Quality Assurance Procedures
OTAQ's Data Acquisition and Management Team (DAMT) has designed two levels of
data checking software available to interested parties: VALDATA and EFLOAD. The
VALDATA is an application for checking input data received from either contractors,
independent testing program operators or from internal EPA test programs and replaces two
FoxPro 2.6 applications, QCSPECS.PRG and ORPHANID.PRG that were previously used for
this purpose. The EFLOAD data checking software is an application for loading input test data
sets into EPA's MSOD Oracle database and replaces the current EFOOLoad and EF99Load
programs. Its input are test data sets released by the Work Assignment Manager (WAM) after
having been successfully processed by the VALDATA program. EFLOAD's output are data sets
that have been successfully loaded into the MSOD Oracle database.
VALDATA Software
All test data is required to be in the input table structure as outlined in section I(b) and
section III before using either of these data checking software. The VALDATA software
checking program is the first level of quality controlling and quality assuring the data. This
program has been designed to be used independently of MSOD and therefore can be deployed
-------
remotely. It is intended to be a data checking tool for principal investigators near or at the
testing site. EPA's intent is that the data gathered in the field be checked immediately
after the completion of a specific mobile source's emission testing or activity gathering
activity. The goal is assure data quality before releasing the mobile source from the testing or
sampling program. . If any issues are raised from VALDATA, or from other data checking
software, the vehicle or equipment that the test was conducted on is still available for further
inquiry or testing before it is put back into normal operation or service.
The VALDATA program checks the data structure and content of the input tables for
conformity to the data set specifications, as they are defined by the structure of the INFILES and
the content of QC_SPECS.DBF. QC_SPECS.DBF is a control table maintained by EPA for the
purpose of testing the content of the input data. The QC_SPECS.DBF is a table used to
determine the suitability of field level data within all of the individual input tables with some
cross level checking of test and vehicle weights. Some examples of fixes to the input data tables
that are normally found from data processed by VALDATA are: 1) work assignment (WA_ID)
names misspelled; 2) fields requiring or not requiring "CAPITAL" letters; 3) fields containing
incorrect NULL value indicator was used; 4) use of non-defined field names or 5) a data field
may exceed an upper or lower bounds for table data (records). In some of these cases, it might
require a change in the QC_SPEC.DBF by EPA to allow the test results in question to pass data
table review. Some data inconsistencies may simply need to be accepted early on in the test
program until enough results have been accumulated that an informed decision can be made
resolving the inconsistency. All errors are written to an error log, XERRLOG.DBF, which is
maintained in the user's Master Data directory. Input data satisfies all the format and context
checks provided by the VALDATA program are "RELEASED" by the user and become eligible
for loading into the EFLOAD program database for further processing and conversion for
loading into the MSOD Oracle database. EPA also runs other data checking programs that
include looking for and identifying "spikes" and "plateaus" or time alignment of emission and
activity results.
EFLOAD Software
EFLOAD is an application for loading Visual FoxPro input test data sets into the MSOD
Oracle database. It replaces the current EFOOLoad and EF99Load programs. Its input are Visual
Fox Pro test data sets released by the Work Assignment Manager (WAM) or test program
coordinator after having been successfully processed by the VALDATA program. EFLOAD's
output are data sets successfully loaded into the MSOD Oracle database. EFLOAD rigorously
rests the input data sets to ensure that he data structures, primary and foreign keys, and NULL
constraints match those of the Oracle MSOD tables. This requires access to the MSOD Oracle
database in order to perform this function and is limited to a few select authorized EPA
personnel. In addition, it provides all the functionality of the past used EFOOLoad and EF99Load
programs including orphan checking, elimination of internal and transact onal duplicates, and
construction of all relational links required by the current business rules within the Oracle
database.

An activity covered by an PEMS/PAMS vehicle.
This result subtype is identified in RESULT by RES KIND = "ACTIVITY".
Used to store a MEASTYPE measurement at the test bag level.
One bag set of a DYNOTEST or RUNLOSS test. (A bag set usually results from two physical bags: one sample
and one background, with the background measurements subtracted from the sample measurements to yield the
bag set measurements).
For DYNOTESTs having a single bag set the bag results are stored here, in addition to being the summary results
for the test as a whole.
Used to store a MEASTYPE measurement at the summary test level.
One "mode" of a possibly multi-mode DYNOTEST whose results are expressed in mass units. The set modes is
defined at any point in time by the translation table for the MODE ID attribute.
Examples of a "mode" include IDLE, IDLE with engine running at 2500 rpm, etc.
One "mode" of a possibly multi-mode DYNOTEST whose results are expressed in mass/time units. The set of
possible modes is defined at any point in time by the translation table for the MODE ID attribute.
Examples of a "mode" include IDLE, IDLE with engine running at 2500 rpm, etc.
This result subtype stores the results of a vehicle chassis exhaust emission tests or in some cases a group of tests.
This table stores information pertaining to the test, or test group as a whole.
Note: The emission summary result fields in this entity are used only to summarize the results of bagged exhaust
emission tests.
This result subtype is identified in RESULT by RES KIND = "DYNOTEST".
The entity name DYNOTEST reflects the fact that a chassis dynamometer is used in most of these tests. The
subtype includes exhaust emission tests for which a dynamometer could be used, but is not required, such as idle
emission measurements. This subtype does not include "running loss" tests, which are performed on a chassis
dynamometer, but which measure both exhaust and evaporative emissions.
A point in time during a DYNOTEST.
Used to store a MEASTYPE measurement at the engine test mode level.
Exhaust Engine Family. These engine families result from the Vehicle Emission Certification process.
An engine or motor used to power an M SOURCE, exclusive of other components of the M SOURCE such as its
structural frame, wheels, etc.
Additional Notes:
1. Since MS TYPE = 2 for all instances of this entity the MS TYPE field is not physically implemented in this
table.
2. MS ID will likely be the engine serial number for instances of this entity, though if some small engines do not
bear unique serial numbers then another solution will have to be found for them.
Sample Queries: To access ENGINE fields in conjunction with their RESULT information the following join
condition would typically be used:
WHERE RESULT. MS_TYPE = 2 AND RESULT.MSJD = ENGINE.MSJD
This result subtype stores an engine "MAP". Maximum available power or torque as a function of RPM.
This result subtype is identified in RESULT by RESJCIND = "ENGINMAP".
Used to store a MEASTYPE measurement at the summary test level.
Steady-state mode used in engine testing on an engine dynamometer. Characterized by a speed, expressed as a
percentage of one of several maximum speeds (rated, idle, or governed central speed, etc), and a load, expressed
as a percentage of the mapped torque at that speed.
A point in time during a DYNOTEST when measuring engine out emissions.

This result subtype stores the results of an engine test performed on an engine dynamometer, exclusive of smoke
opacity measurement. This subtype is identified by RES KIND = "ENGTEST".
A point in time within an ENGTEST.
A non-core measurement associated with a point in time in an engine test (i.e. an ENGTIME).
The results of one steady-state mode of an engine dynamometer test. (Only used to store steady-state results.)
Evaporative Engine Family. These families are a product of the vehicle emission certification process.
Used to store a MEASTYPE measurement at the summary test level.
Evaporative Emission Standard. Used to store standards applicable to late model (1994 and later) vehicles.
(Earlier standard information was simpler and is stored within the Vehicle Table itself.)
The design of this table is very much influenced by the need to obtain this information from EPA's Certification
and Fuel Economy Information System (CFEIS ), for this reason this should be considered a "foreign" design
whose attributes are not well integrated with the MSOD.
This result subtype stores the results of an evaporative emission test. This table stores information pertaining to
the test as a whole.
This result subtype is identified in RESULT by RESJCIND = "EVAPTEST".

measure both exhaust and evaporative emissions.
One point in time during an evaporative emission test.
Exhaust Emission Standard. Used to store standards applicable to late model (1994 and later) vehicles. (Earlier
standard information was simpler and is stored within the Vehicle Table itself.)
The design of this table is very much influenced by the need to obtain this information from EPA's Certification
and Fuel Economy Information System (CFEIS ). For this reason this table design should be considered a
"foreign" design whose attributes are not well integrated with the MSOD.
A particular batch of fuel that can be used to power mobile sources during emission tests.
Unlike a FUEL, which is a general kind of fuel, instances of this entity represent a physical batch of fuel that has
measured properties.
A kind of fuel used to power a mobile source during a particular test.
Example instances:
Diesel Fuel, Indolene, Tank fuel (whatever was present in the fuel tank when the vehicle was obtained), etc.
While some kinds of fuel may be purchased or blended to nominal specifications for octane, volatility, alchohol
content etc., e.g. "clean air act baseline fuel", instances of this entity are always a conceptual "kind" of fuel and
not a physical batch of fuel.
This result subtype stores the results of an analysis of the fuel being used in the mobile source. This result
subtype is identified in RESULT by RES_KIND = "FUELCHEM".
This result subtype is identified in RESULT by RESJCIND = "INSPECT".
This result subtype is used to store the results of the emission component inspection often referred to as the Ml
maintenance inspection, or just Ml maintenance. This top level subtype entity is used to store information about
the inspection as a whole.
This result subtype can also be used to store observational comments pertaining to a Mobile Source, even when
no parts or systems are actually inspected.
A broad area of interest within the field of Mobile Sources, in association with a WKASSIGNment which
addresses that interest.
This area contains information organized by particular kinds of RESULTS. We often refer to these as RESULT
subtypes. Every process which records information about or which modifies a mobile source of air pollution such
as a VEHICLE or ENGINE is considered to be some kind of a RESULT.
So kinds of results include subtypes like PROCUREments which are not normally considered test results. This
is because information such as the procurement date and the odometer reading of the vehicle, etc. is recorded

when the vehicle is obtained.
Each row in the RESULT table includes the res kind field, which identifies what kind of a RESULT it is.
LTIME IN is to store measurements used to calculate the mass per unit time measurements found in the input
table TIMEJN during a lab test.
A physical object which can move, and which produces outdoor air pollution. Historically interest has been in
passenger cars and trucks designed to be driven on roadways, and the internal combustion engines used to power
such vehicles. Future data will pertain to other types of mobile sources such as off-road vehicles, boats, farm and
construction equipment, etc., and the engines used to power such equipment.
Additional Notes:
1 . EPA and the principal air- pollution-regulating statutes make a fundamental distinction between mobile and
stationary sources of air pollution such as factories and power plants.
2. This entity is broken down into subtype entities based on MS TYPE. Fields common to all or most types of
mobile sources will be stored in this table. Fields particular to certain types of mobile sources will be stored in
subtype tables.
Sample Queries: To access M SOURCE fields in conjunction with their RESULT information the following join
condition would typically be used:
WHERE RESULT.MS TYPE = M SOURCE.MS TYPE AND
RESULT.MSJD = M_SOURCE.MS_ID
Example Instances:
Passenger cars, trucks, busses, farm tractors, locomotives, ships, airplanes, portable generators, and power
lawnmowers are all M SOURCES.
A trailer is not (does not produce air pollution). A gasoline service station is not (can not move). A transportation
activity such as "shipping" is not (not an object). A class of mobile sources such as "LDTs" (light duty trucks),
about which we might collect for example population, activity, or usage data, is likewise not an M SOURCE.
A type of numeric, "non-core", emission-related measurement, e.g. methane emissions in grams per mile, not
usually performed.
Note: This table does not store a result measurement, but information about a kind of measurement.
Used to store a MEASTYPE measurement at the test mode level.
A point in time within a DYNOMODE.
An engine or motor used to power a mobile source of air pollution (such as a VEHICLE), exclusive of other
components such as its structural frame, wheels, etc.
Note for advanced users: This table is actually the inner join of the database tables M SOURCE and ENGINE.
The join is performed both to enhance query performance and to simplify query formulation by hiding the
existence of the separate M SOURCE table from the user.
A motor vehicle (including cars, trucks, motorcycles, and off road vehicles) inclusive of its engine and chassis,
having a unique vehicle identification number (VIN).
Note for advanced users: This table is actually the inner join of the database tables M SOURCE and VEHICLE.
The join is performed both to enhance query performance and to simplify query formulation by hiding the
existence of the separate M SOURCE table from the user.
OBD2 scan code. Contains information about the code itself, e.g. its meaning.
This result subtype is used to store summary level information pertaining to a scan of a vehicle's on board
diagnostic system. While both level 1 and level 2 on board diagnostic systems scans are supported by this data
structure, data collected on level 1 systems prior to 1999 are stored as part of the vehicle inspection data.
This result subtype is identified in RESULT by RES KIND = "OBDSCAN".
This table is used to store information pertaining to the scan as a whole.
This result subtype stores information from the Owner's questionnaire, and, where collected, summary
information from the fuel economy postcard survey.

Used to store a MEATYPE measurement for PEMS/PAMS devices on vehicles.
Used to store a MEASTYPE measurement at the summary test level.
This Result Subtype stores the outcome of an evaporative system pressure check. In cases where an attempt was
made to perform a pressure check, but it could not be performed, the reason for this is stored.
This result subtype is identified in RESULT by RES KIND = "PRESSTST".
The obtaining of an M SOURCE for testing. Usually a series of tests is performed during the M SOURCE'S stay
at a test facility.
This result subtype is identified in RESULT by RES KIND = "PROCURE".
Historically OTAQ's emission factor testing program can be considered to have always "procured" a vehicle or
engine prior to testing it, but it is not a logical requirement of the database that a PROCURE instance exist for
every RESULT if no information of this nature is collected, e.g. Vehicles observed driving on the road would not
have to be "procured".
Since research questions (QUESTION) and work assignments (WKASSIGN) have a many-to-many relationship
this entity is needed to "associate" them.
Technically this entity represents one work assignment's contribution to answering one research question.
A research question on which RESULTS are intended to address.
Used to store a rate MEASTYPE measurement at the test mode level.
Used to store a running loss MEASTYPE measurement at the bag level.
Used to store a MEASTYPE measurement at the test time point level.
A repair is a procedure performed on a Mobile Source intended to improve its performance, which is assumed to
affect all subsequent RESULTS on that Mobile Source.
This result subtype is identified in RESULT by RES KIND = "REPAIR".
This table is used to aggregate RESULT instances into a few different subtypes.
Any observation, measurement, or modification to an M SOURCE including:
1) Information pertinent to the procurement of the M SOURCE.
2) An outcome of any test procedure performed on an M SOURCE, such as an exhaust emissions test or an
evaporative emissions test.
3) Observations of the M SOURCE, e.g. a questionnaire about the M SOURCE submitted by the owner.
4) Repairs or modifications made to the M SOURCE which could effect future measurements.
Additional Notes:
1 . This entity is broken down into an incomplete collection of dependent subtype entities based on its
RES KIND field. Additional result subtypes will be added as are needed.
A portion of a road test. This portion must correspond to a single, contiguous period of time within the time

This result subtype stores the results of a vehicle exhaust emission test performed during on-road driving. This
table stores information pertaining to the test as a whole.
This result subtype is identified in RESULT by RESJCIND = "ROADTEST".
The entity name ROADTEST reflects the fact that the vehicle has been equipped with on board exhaust emission
measurement instrumentation and that the emission measurements can therefore be made during actual use rather
than in a laboratory.
A point in time during a ROADTEST.
A trip traveled by an on-road vehicle.
This result subtype is identified in RESULT by RES KIND = "ROADTRIP".
This result subtype is similar to a ROADTEST. The primary purpose of a ROADTEST is to measure exhaust
emissions. The purpose of a ROADTRIP is to measure other aspects of the vehicle's usage or activity.
The evaporative emissions for a portion of a "running loss" test, identified by "bag number" within the test.
This result subtype stores the results of a vehicle chassis running loss emission test. Like DYNOTESTs, these are
performed on a chassis dynamometer and exhaust emission measurements are taken. Unlike DYNOTESTS,
however:
1. Evaporative running losses are measured during portions of the test.
2. An attempt is made to heat or cool the vehicle's fuel tank as necessary to simulate the temperature pattern it
would experience in on-road driving.
This result subtype is identified in RESULT by RESJCIND = "RUNLOSS".
This table is used to store results which pertain to the test as a whole; no attempt is usually made to summarize the
emission results, exhaust or evaporative, for the test as a whole.
Emission component system inspection.
An Individual scan code resulting from a scan of a level 1 on board diagnostic system.
An Individual scan code resulting from a scan of a level 2 on board diagnostic system.
A time point in a SCHEDULE.
Sample Queries: To use this table in conjuction with the SCHEDULE table the following join condition would be
used.
. where sched_pt.sched id = schedule, sched id
Example Instances: 1) For schedule cdh226, the speed should be 23.5 mph at 20 seconds 2) for schedule rtd2, the
temperature should be
83. 9 Fat 90 minutes.
Functional relation which gives values for one or more controlling test parameters, such as the speed a vehicle
should be traveling, the temperature that a SHED should maintain, or the torque and rpm of an engine throughout
the time of a test procedure.
Schedules are often also referred to as "cycles" though the Schedule term is considered preferable since there is
nothing circular, regular or repeating about most test schedules.
Additional notes: Only items pertaining to the schedule as a whole belong in this table, e.g. descriptions,
average or maximum values of the entire schedule.
Sample Queries: To use this table in conjunction with the RESULT entity the following join condition would be
used
where schedule. sched id = result. sched id
Example Instances:
(1) EPA Urban Dynamometer Driving Schedule for Light-Duty Vehicles and Light-Duty Trucks.
(2) EPA Engine Dynamometer Schedules for Heavy-Duty Otto-Cycle engines.

(3) Temperature schedules for evaporative emission tests.
These are the summary information pertaining to each schedule or "cycle" For example: Total length of the
schedule, maximum, minimum or average speed of the schedule or highest acceleration in schedule.
This result subtype stores the results of a smoke opacity test. This subtype is identified by RES KIND =
"SMOKETST".
This area deals with the emissions standards applicable to vehicles.
Prior to the 1995 model year, this database considers that a single set of emission standards apply to each vehicle.
This standards information is contained within the VEHICLE table itself, using the fields evapstd, noxstd, thcstd,
pmstd, etc.
Beginning with the 1995 model year in the United States the situation became more complicated with more sets
of standards applying to each vehicle. Within this area the EXSTSTAN table contains the exhaust emission
standards applicable to a vehicle, while the EVAPSTAN table contains the evaporative emission standards
applicable to a vehicle.
One mode of a smoke test procedure.
Emission Component System e.g. "Induction", etc. "OBD", etc.
Work effort in which produced the RESULT as classified historically. Usually corresponded to a contract task
or analogous internal effort.
Note: The WKASSIGN entity was intended to subsume this TASK entity. Until WKASSIGN is fully populated,
however, this TASK entity will be used to store more sparse information which is available from the "old
database" about the work efforts which produced the older RESULTS.
Test procedure used to produce a RESULT.
An example would the Federal Test Procedure (FTP), though most other test procedures are not as completely
defined.
Notel: Historically this concept was termed "Test Type" by AMD. Instances of this entity are an evolution of
the domain of the former Test Type field, though in some cases multiple Test Type values have been combined
into a single Test Procedure instance and visa versa.
Note2: Conceptually Test Procedure is a different idea from Test Schedule. For example if two test procedures
differ only in the Schedule used then ideally they should be considered the same Test Procedure. In practice,
however, this has not been fully implemented because of the strong identity of some Test Procedures with Test
Schedules and the lack of identification of true test "Procedures". Some grouping of Schedules into Test
Procedures has been achieved, however, where identifiable groups of Schedules are involved, such as the
"Facility" driving schedules for exhaust emission tests, or EPA's set of "Speed Correction" cycles.
This area contains information about the test programs or projects that conducted the emission testing which
produced the individual results stored in this database. We sometimes refer to this as the test "metadata". For
many reasons it is important to consider the characteristics of individual test programs when using the data
because only here are details described as to how vehicles were recruited and the test program conducted.
Within this area, the WKASSIGN (Work Assignment) table contains information about test data loaded more
recently. It generally includes the contract and work assignment numbers if the work was performed under
contract to EPA, and pointers to the statement of work, work plans, or final reports.
For older data imported into this database from EPA's older Emissions Factor (EF) database, less information is
generally available. What is available for this older data is contained in the TASK table.
The proto id field in the RESULT table identifies any TASK associated with a RESULT. The wa id field in the
RESULT table identifies any WKASSIGN associated with a RESULT.
Used to store a MEASTYPE measurement at the summary test level.
Used to store a MEASTYPE measurement pertaining to a particular time in a test.
A trip traveled by a vehicle using a PEMS/PAMS device.

Entity
VEHICLE
A motor vehicle, inclusive of its engine and chassis, having a unique (within this entity) vehicle identification
number (VIN).
Additional Notes:
1. It may be necessary at some point to distinguish between light duty and heavy duty vehicles. If made such a
distinction would probably be based on the vehicle certification regulations at CFR 40 Part 86 section 082-2.
Most fundamentally if this distinction were made a light duty vehicle instance, if certified for compliance with air
emission regulations, would be certified as an entire vehicle or "chassis", whereas a heavy duty vehicle instance,
would have its engine certified.
2. Since MS_TYPE = 1 for all instances of this entity the MS_TYPE field is not physically implemented in this
table.
3. MS_ID is the Vehicle's Identification Number (VIN) for instances of this entity.
Sample Queries: To access VEHICLE fields in conjunction with their RESULT information the following join
condition would typically be used:
WHERE RESULT.MS_TYPE = 1 AND RESULT.MSJD = VEHICLE.MSJD
Example Instances:
This entity includes motorcycles and off road vehicles.
WKASSIGN
A work assignment, whether contracted or performed in_house, which produces RESULTS. Often also referred
to as a "test program".
These efforts have often been performed by vehicle testing contractors under work assignment contracts. This
entity represents a broader view of this fundamental construct.

P CRITER D
Beflnltton
The abbreviated name used to describe additional vehicle-condition-specific criteria
that was or was not done.
Procurement criteria. A categorical attribute with two valid entries: GENERAL or
CONDITIONAL.
GENERAL pertains to projects where vehicles were accepted for testing without
additional, vehicle-condition-specific criteria. For example, a task might intend to
recruit 1997 model year light-duty trucks with less than 6,000 pounds gross vehicle
weight. If the first truck meeting these criteria and willing to be tested is accepted
for testing, then the procurement would be considered GENERAL. (Rejecting
vehicles for testing safety reasons is not considered as an additional criteria.)
Most EPA test data is usually not procured in a purely random manner. Vehicle
class criteria (i.e., model year) is commonly used as a criteria to limit the scope of
the procurement and maximize the data sample in the areas of interest. This "non-
random" procurement is normally not a problem as long as the analysis of the data is
stratified by the vehicle class criteria.
CONDITIONAL refers to tasks which included additional, vehicle-condition-
specific criteria in addition to any vehicle class criteria. The additional criteria is
based on the condition of the vehicle (i.e., mileage, emission level, vehicle owner,
etc.) and not the vehicle as manufactured (i.e., fuel injection, catalyst type, model
year, etc.). Users should refer to the text of the work assignment which recruited the
vehicle to determine the precise conditions used for recruitment.

A foreign key back into RESULT. Identifies any most immediately following
RESULT instance which is a replicate (repeat) of this one. A departure from the
relational model.
May be used to relate a RESULT to another RESULT of which it considered a part.
This relationship was originally established to relate the FTP, US06 and SC03
portions of the SFTP to the SFTP summary calculations (All four being considered
DYNOTESTs.) The SFTP is considered the Result Group and the FTP, US06 and
SC03 are considered to belong to this Result Group.
A value of zero is used to indicate that a particular RESULT is not part of a higher-
level group.
General kind of mobile source:
1 = Vehicle
2 = Engine.
Mobile source identifier. For vehicles their VIN would be used. For engines, their
serial number, probably in conjunction with their manufacturer code.
RESULT kind. Used to identify which subtype this result belongs to. Overall intent
is to aggregate RESULT instances into as few different subtypes as practical. E.g. all
vehicle dynamometer tests may be one subtype, all SHED tests another. Legal values

Task number. Field has this name because thought at one point was to call these
"protocols".
A number intended to identify the contract, as historically classified, to which a Task
belongs.
Test program, as historically classified, to which the Task belonged. This data
element formed the "SUFFIX" portion of tablenames in an older, non-relational,
implementation of this database.
Brief task title or description.
Procurement criteria. A categorical attribute with two valid entries: GENERAL or
CONDITIONAL.
GENERAL pertains to projects where vehicles were accepted for testing without
additional, vehicle-condition-specific criteria. For example, a task might intend to
recruit 1997 model year light-duty trucks with less than 6,000 pounds gross vehicle
weight. If the first truck meeting these criteria and willing to be tested is accepted for
testing, then the procurement would be considered GENERAL. (Rejecting vehicles
for testing safety reasons is not considered as an additional criteria.)
Most EPA test data is usually not procured in a purely random manner. Vehicle class
criteria (i.e., model year) is commonly used as a criteria to limit the scope of the
procurement and maximize the data sample in the areas of interest. This "non-
random" procurement is normally not a problem as long as the analysis of the data is
stratified by the vehicle class criteria.
CONDITIONAL refers to tasks which included additional, vehicle-condition-specific
criteria in addition to any vehicle class criteria. The additional criteria is based on the
condition of the vehicle (i.e., mileage, emission level, vehicle owner, etc.) and not the
vehicle as manufactured (i.e., fuel injection, catalyst type, model year, etc.). Users

An activity is a collection of trips traveled by an PEMS/PAMS non-road vehicle.
This result subtype is identified in RESULT by RES KIND = "ACTIVITY".
One bag set of a DYNOTEST. (A bag set usually results from two physical bags: one sample and one
background, with the background measurements subtracted from the sample measurements to yield the bag set
measurements).
A single set of bag test results are stored here, as well as at the summary test level. Many DYNOTESTs
involving bagged emission measurements utilize multiple bag sets.
Used to store a MEASTYPE measurement at the test bag level.
This input table stores the results of a vehicle chassis exhaust emission test whose results are expressed in grams
per mile. This test is eventually stored as entity DYNOTEST.
This input table stores information pertaining to the test as a whole.
Note: The emission summary result fields in this entity are used only to summarize the results of bagged
exhaust emission tests.
This result subtype stores an engine "MAP". Maximum available power or torque as a function of RPM.
This result subtype is identified in RESULT by RES KIND = "ENGINMAP".
The results of one steady-state mode of an engine dynamometer test. (Only used to store steady-state results.)
Used to store a MEASTYPE measurement at the engine test mode level.
A point in time during a DYNOTEST when measuring engine out emissions.
A point in time within an ENGTEST.
This Input Table Represents Procurement of both Equipment and Engine
A non-core measurement associated with a point in time in an engine test (i.e. an ENGTIME).
This result subtype stores the results of an engine test performed on an engine dynamometer, exclusive of
smoke opacity measurement. This subtype is identified by RES KIND = "ENGTEST".
One point in time during an evaporative emission test.
This entity stores the results of an evaporative emission test. This table stores information pertaining to the test
as a whole.
A particular batch of fuel that can be used to power mobile sources during emission tests.
Unlike a FUEL, which is a general kind of fuel, instances of this entity represent a physical batch of fuel that has
measured properties.
Freeze frame data.
This result subtype stores the results of an analysis of the fuel being used in the mobile source.
This input entity is used to store the results of the emission component inspection often referred to as the Ml
maintenance inspection, or just Ml maintenance.
This top level entity is used to store information about the inspection as a whole.
LTIME IN is to store measurements used to calculate the mass per unit time measurements found in the input
table TIME IN during a lab test.
A single point within an engine map.
A type of numeric, "non-core", emission-related measurement, e.g. methane emissions in grams per mile, not
usually performed.
Note: This table does not store a result measurement, but information about a kind of measurement.
This input entity is used to store summary level information pertaining to a scan of a vehicle's on board
diagnostic system. Both level 1 and level 2 on board diagnostic systems scans are supported by this data
structure.
This table is used to store information pertaining to the scan as a whole.
OBD2 scan code. Contains information about the code itself, e.g. its meaning.
Emission component part code inspection.
A portion of a roadtest. This portion must correspond to a single, contiguous period of time within the time
period of the complete test.
Used to store a MEASTYPE measurement at the test time point level.
This Result Subtype stores the result of an evaporative system pressure check.
The type of repair performed on a vehicle.
Any observation, measurement, or modification to an M SOURCE including...
Information pertinent to the procurement of the M SOURCE.
An outcome of any test procedure performed on an M SOURCE, such as an exhaust emissions test or an
evaporative emissions test.

Additional Notes:
1 . This entity is broken down into an incomplete collection of dependent subtype entities based on its
RES KIND field. Additional result subtypes will be added as are needed.
Used to store a MEASTYPE measurement at the test time point level.
This entity communicates the results of a vehicle exhaust emission test performed during on-road driving. These
results are ultimately stored as a ROADTEST type RESULT. This table stores information pertaining to the
test as a whole.
The entity name ROAD IN reflects the fact that the vehicle has been equipped with on board exhaust emission
measurement instrumentation and that the emission measurements can therefore be made during actual use
rather than in a laboratory.
A point in time during an on-road exhaust emission test.
The results of a vehicle chassis running loss emission test, eventually stored as entity RUNLOSS. This table
stores information pertaining to the test as a whole.
A portion of a "running loss" test, identified by "bag number" within the test.
An individual scan code resulting from a scan of a level 1 on board diagnostic system.
An individual scan code resulting from a scan of a level 2 on board diagnostic system.
One mode of a smoke test procedure.
This result subtype stores the results of a smoke opacity test. This subtype is identified by RES KIND =
"SMOKETST".
A point in time during a DYNOTEST.
Used to store a MEASTYPE measurement at the summary test level.
Atrip traveled by an PEMS/PAMS non-road vehicle.
This result subtype is identified in RESULT by RESJCIND = "TRIP".
This result subtype is similar to a ROADTEST. The primary purpose of a ROADTEST is to measure exhaust
emissions. The purpose of a ROADTRIP is to measure other aspects of the vehicle's usage or activity.
One or more OBD code(s) occurring at a point in time during a trip.
A point in time during a trip.
A table containing attributes that describes a vehicle.

Identification number assigned to the RESULT by a test contractor. (Hopefully
uniquely identifies RESULT instances within a given contractor.)
Not used for analytical purposes. But could help locate contractor's records pertinent
to this RESULT.
Fuel batch identification.
Identifies the specific test procedure used. A more detailed classification than
RES KIND. Based largely upon values of TEST TYPE in earlier design.
Conceptually distinct from the driving or operational schedule used.
Work Assignment (or equivalent for TSD) name.
Schedule identification.
TRUE is this test is a replicate of one already entered, otherwise false.
Contains the ctr 1st id of any test, of which this is a component part. A blank value
indicates that this test is not part of a higher-level test group.
General kind of mobile source:
1 = Vehicle
2 = Engine.
Mobile source identifier. For vehicles their VIN would be used. For engines, their
serial number, probably in conjunction with their manufacturer code.
RESULT kind. Used to identify which subtype this result belongs to. Overall intent
is to aggregate RESULT instances into as few different subtypes as practical. E.g. all
vehicle dynamometer tests may be one subtype, all SHED tests another. Legal values
defined by RES KIND translation table.
Numeric code uniquely identifying the general type of fuel used. Sometimes referred
to as the "gross fuel type".
Result date.
Time of day of the start of the result. Stored as a 5 character string HH:MM.
Location where test was conducted. Legal values defined by SITE translation table.
Nominal temperature at which test was to be conducted. Expressed in degrees
Fahrenheit.
Nominal absolute humidity at which test was to be conducted. Expressed in grains of
water per pound of dry air.
Indication of any special conditions or "disablements" performed on the mobile
source for particular tests. A value of zero indicates that no special condition or
disablement to the vehicle was performed. Positive values indicate a particular
disablement or set of disablements. Legal values defined by DISABLE translation
table.
Number of test modes involved in this result. Data for individual chassis test modes
is stored in the DYNOMODE table; data for individual engine dynamometer test
modes is stored in the ETSTMODE table.
Identifies any minor deviation from normal test procedure indicated by "test_proc".
Legal values defined by TEST MOD translation table.
