Voluntary Mobile Source Programs: Crediting
Innovation and Experimentation
This brochure provides basic information about the Voluntary
Mobile Source Emissions Programs (VMEPs) policy and
outlines the federal process a state would go through to receive
credit for their VMEPs in a State Implementation Plan (SIP).

Quantification of
Episodic Control
This report provides an in-
depth examination of epi-
sodic emission control
programs for five selected
areas (Baltimore,  Sacra-
mento, San Francisco, Cin-
cinnati, and Dallas) and the
techniques used to evaluate
the effectiveness of the
individual control measures
included in the programs.
SIP Development Guidance: Commuter Choice
This guidance document assists
States and Federal agencies to
calculate the emissions benefits of
commuter choice programs.  States
can experiment with incorporating
commuter choice programs into
their SIPs in order to attain and
maintain National Ambient Air
Quality Standards. Commute
benefits, sometimes called transpor-
tation 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 work. (EPA420-R-98-007)

Background Information for Land Use SIP Policy
This report identifies and evaluates if and how emissions benefits
of various land use measures that affect travel behavior are
accounted for in current SIPs. (EP A420-R-98-012)

Index of Transportation Measure Quantification Efforts:
Methodology Matrix
This methodology matrix provides a clearly organized, easy-to-
use summary of available methodologies for evaluating a given
transportation measure, the strengths and weaknesses of those
methodologies, and examples of research and evaluation efforts
that have utilized each of those methodologies. The matrix
covers 27 different transportation measures, and summarizes and
analyzes 38 distinct quantification methodologies.

IRAQ Web Site Additions
Transportation Control Measures (TCM) Database

The TCM database is an on-line searchable directory on TCM
programs operating around the country. It also has 14 technical
overviews on different types of TCMs. The technical overviews
include descriptions of how the measures work.

Commuter Choice Web Page

This home page gives you a list of specific items relating to
EPA's Commuter Choice programs. The web pages include
technical overviews,  fact sheets, a SIP guidance document, tax
treatment of employer-provided commute benefits, examples of
commuter choice measures, frequently asked questions, and links
to other agencies and organizations promoting commuter choice.

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. Infor-
mation 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.

Voluntary Measures Web Page

This expanded home page now includes information on designing
and implementing a voluntary program, voluntary measure
technical, financial and training assistance as well as specific
voluntary measure program guidance.
