 http ://www. epa.gov/oms/traq
Survey of Episodic Control Programs
This resource for episodic control information includes collected data on episodic control programs
currently implemented or under development across the country.

Market Incentives Resource Center (MIRC) for Air Quality Programs
The MIRC provides information on market incentive programs (e.g., transportation pricing and
emissions trading programs) in the U.S.

Smart Travel Resource Center (STRC)
This electronic clearinghouse provides access to summaries of public education programs around the
country that address transportation and air quality issues.

Transportation Control Measures (TCM) Database
The TCM database is an on-line searchable directory on TCM programs operating around the coun-
try. It also has 14 technical overviews on different types of TCMs. The technical overviews include
descriptions of how the measures work.

Transportation-Related Grants Database
The Transportation-Related Grants Database was developed to facilitate information exchange
among transportation practitioners, public decision makers, industry, consultants, public interest
groups and others who support travel-related activities which minimize emissions from mobile
sources. Information is provided on more than 50 EPA funded transportation-related projects from

around the nation. These projects and programs focus on encouraging travel-related activities which
minimize emissions from mobile sources.
 Transportation Conformity
 Conformity is a way to ensure that federal funding and approval are given to those transportation
 activities that are consistent with air quality goals. Conformity rulemakings, accompanying out-
 reach materials, and policy memoranda are available through the IRAQ Website.
Transportation Conformity: A Basic Guide for State and Local Officials
The U.S. Department of Transportation (DOT) published this guide in 1997, in coordination with
EPA. The guide provides a general overview of conformity: defines conformity, identifies what types
of transportation projects are subject to conformity, identifies conformity "players," describes play-
ers' responsibilities, and explains how the public is involved in the conformity process. The basic
guide is geared toward local and state elected officials, advocacy groups, and the general public.
Interested parties can obtain the guide at no cost by calling U.S. DOT's Publications Hotline at (202)

Linking Transportation and Air Quality Planning: Implementation of the Transportation
Conformity Regulations in 15 Nonattainment Areas
(EPA420-R-99-011, April 1999) This report, by researcher Arnold Howitt of Harvard's Kennedy
School of Government, takes an in-depth look at transportation conformity implementation in 15
study areas from 1991 through January 1998. Using a case-study approach, the report explores the
conformity rule's impact on transportation planning, air quality planning, and the relationships of the
involved agencies and constituencies. The report was jointly funded by U.S. EPA and U.S. DOT.
(Study areas: Atlanta, GA; Baltimore, MD; Boston, MA; Charlotte, NC; Chicago, IL; Denver, CO;
Houston, TX; Milwaukee, WI; Northern New Jersey; New York, N.Y.; Philadelphia, PA; Phoenix,
AZ; Portland, OR; Salt Lake City, UT;  and San Francisco, CA.)

This report would be of interest to conformity implementers and others that have an interest in
transportation planning decisions; it can be found on the Internet at: http://www.epa.gov/oms/transp/
 Voluntary Mobile Source Emission Reduction Program
 Voluntary mobile source emission reduction programs rely on voluntary actions of individuals or
 other parties for achieving emission reductions.
Quantification of Episodic Control Programs
(EPA420-R-97-006, May 1998) This report provides an in-depth examination of episodic emission
control programs for five selected areas (Baltimore, Sacramento, San Francisco, Cincinnati, and
Dallas) and the techniques used to evaluate the effectiveness of the individual control measures
included in the programs.

that have utilized each of those methodologies.

Voluntary Measures and SIP Credits Policy
This October 23, 1997, memorandum from Richard D. Wilson, Acting Administrator for the Office
of Air and Radiation, presents guidance for adopting Voluntary Mobile Source Emissions Programs
into State Implementation Plans (SIPs). The guidance allows for regional EPA approval of a number
of community-based environmental protection strategies related to transportation or mobile source
emissions. (Available from the TRAQ Information Request Line.)

State Implementation Plan Development Guidance: Using Emission Reductions from Com-
muter Choice Programs to Meet Clean Air Act Requirements
(EPA420-R-98-007, March 1997) This guidance document assists states and federal agencies to
calculate the emissions benefits of commuter choice programs. By issuing this guidance, EPA hopes
to encourage states to experiment with incorporating commuter choice programs into their SIPs in
order to attain and maintain National Ambient Air Quality Standards. Commute benefits, sometimes
called transportation fringe benefits, are items such as parking spaces, transit passes and vanpool
subsidies, provided by employers to defray the costs to employees of transportation to  and from

Commuter Choice - Benefits for Commuters, Companies, Communities
(EPA420-F-99-009, April 1999) The Commuter Choice Brochure provides introductory information
about the benefits of commuter choice for commuters, companies, and communities. The brochure
also lists where additional information may be found.

 A popular means to reduce vehicle emissions by encouraging changes in the ways people travel.
Transportation Control Measure Information Documents
(EPA400-R-92-006, March 1992) This report contains information documents on the 16 broad
categories of TCMs as required and described under Section 108(f) of the Clean Air Act Amend-
ments of 1990. Each of the TCM categories is described in terms of its objectives, variations in the
ways it may be implemented, representative examples of actual usage, expected transportation and
emissions impacts, other potentially important considerations, and a set of implementation guide-
lines that can be followed by state, regional, and local agencies. (This document is not available
electronically. It is available from the National Technical Information Service [NTIS] at 800-553-
6847. NTIS# PB92-172566/REB)

Methodologies for Estimating Emission and Travel Activity Effects of TCMs
(EPA420-R-94-002, July 1994) This report provides a step by step approach for quantitatively
estimating the travel and emissions changes that are possible from implementing a number of trans-
portation control measures. The report includes equations for calculating changes in the number of
trips, vehicle miles traveled, and speed, as well as methods for estimating emission effects of these
travel activity changes.

Benefits Estimates for Selected TCM Programs
(EPA420-R-98-002, March 1999) This report illustrates the use of'EPAs Methodologies for Estimat-
ing Emission and Travel Activity Effects of TCMs by applying the methodologies to the estimation of
