TDM Evaluation Reports

Atlanta TDM Framework Evaluations (Atlanta, GA. )

Anticipated as a phased research and measurement program, in December 1999 the Georgia Department of Transportation (GDOT) awarded the Center for Transportation and the Environment (known at the time as the Southern Coalition for Advanced Transportation (SCAT)) a contract to conduct a research and measurement program. The goals of the contract are the following:

• To enhance the media campaign program area;
• To evaluate the qualitative and quantitative impacts of each of the three program areas (media campaign, employer and individual outreach services, and regional supporting programs and services); and
• To establish a consistent evaluation protocol and reporting procedure across the program areas.

Florida Statewide Commuter Assistance Program Evaluation (Miami-Ft. Lauderdale and Tampa Bay)

Statewide Commuter Assistance Program Evaluation Project The Statewide Commuter Assistance Program (CAP) Evaluation Research Project was commissioned and funded by the Florida Department of Transportation's Research Ideas Program. The purpose of this research project was to provide a systematic evaluation of the performance of Florida's commuter assistance programs from two perspectives: 

1. Impact on the commuting patterns and awareness of the general public; and, 

2. Impact on the commuting patterns and awareness of each CAP database of commuters, which are comprised of commuters who have called or otherwise applied for commuting assistance and/or information. 

There were three documents produced as part of this project:  

• Performance Measures for South Florida Commuter Services and Bay Area Commuter Services 
  This report focuses on the performance measures available to Florida Commuter Assistance Program (CAP) offices to determine program progress and/or effectiveness. The performance measures are divided into three sections: 

  • required performance measures 

  • optional performance measures 

  • other performance measures. 

As the name suggests, required performance measures are those that the Florida Department of Transportation (FDOT) has mandated that all CAP offices in Florida must track and report on at least an annual basis. These performance measures are specified on pages 8-9 of the Commuter Assistance Program procedures, dated May 5, 1997. District optional performance measures are those that FDOT have determined are appropriate for some of the CAP programs and, at CAP and FDOT District option, can be reported to show progress and/or performance. Other performance measures are those that can help a CAP illustrate the effectiveness of their programs in meeting program or regional objectives.

Commute Trip Reduction (State of Washington)

The Washington State Legislature created the Commute Trip Reduction (CTR) Law in 1991 with the goals of reducing traffic congestion, air pollution, and petroleum consumption in the state's nine most populous counties. This 2001 biennial report from the CTR Task Force reviews the program's performance and recommends a legislative strategy to achieve even greater success in the future.

This report also celebrates the 10th anniversary of the CTR law. Since the program was created, its goals have become even more urgent. Travel growth on Washington highways is expected to increase by 79 percent between 1997 and 2020. This is the equivalent of eight new cars on our roadways for every ten that are already there. Meanwhile there is less money to support state transportation programs.

State of the Commute Survey (Washington, DC area)

State-of-the-Commute Survey conducted for the Commuter Connections program of the National Capital Region Transportation Planning Board at the Metropolitan Washington Council of Governments (COG). Commuter Connections provides a wide range of transportation information and services to commuters in the Washington metropolitan area designed to inform them of the availability and benefits of alternatives to driving alone and to assist them to find alternatives that fit their commute needs.  Commuter Connections administers these services, called Transportation Emission Reduction Measures (TERMs), as part of a regional effort to reduce vehicle trips, vehicle miles of travel, and air emissions resulting from commute travel.

The SOC survey serves several purposes. First, it documents trends in commuting behavior, such as commute mode shares and distance traveled, and prevalent attitudes about specific transportation services that are available to commuters in the region. Second, the SOC survey will be used to help estimate the impacts of some TERMs, such as Guaranteed Ride Home and the Telework Resource Center, which might have an influence on the commuting habits of the population-at-large as well as on commuters who directly participate in the TERMs. Finally, by querying respondents about commuters’ sources of information on alternative modes and their reasons for choosing alternative modes for commuting, the survey results will attempt to suggest how other commute alternative programs and marketing efforts might be influencing commuting behavior in the region.
