Transportation Demand Management (TDM)

TDM provides alternatives to driving alone. It is a strategy used in many communities and regions to help manage the demand for, and improve the performance and efficiency of, their transportation systems. TDM efforts are often focused on work trips, offering commuters options to replace driving alone. Commuters are encouraged to share the ride by carpooling or vanpooling, riding public transit, or walking or biking to work. Teleworking, as well as flexible and alternative work schedules are also TDM choices.

TDM options can help reduce congestion and provide quantifiable reductions in mobile source pollutants that are precursors to the formation of smog.  Commuters also report numerous benefits including reduced commute-related stress and lower commuting costs

TDM Measurement and Evaluation

CTE has nationally recognized expertise in developing and evaluating TDM strategies that have measurable results including, but not limited to:

  • The qualitative and quantitative impacts of program areas such as media/marketing campaigns, employer and individual outreach services, and regional supporting programs and services
  • The establishment of consistent regional evaluation protocols and reporting procedures
The development and implementation of a single, structured evaluation plan including enhanced data collection tools, methodologies, and performance measures resulting in more rigorous and inclusive assessment of TDM effectiveness.

Current Projects

Evaluation of Triangle J TDM Programs FY2010 - CTE is leading an effort to assist the Triangle J Council of Governments in to develop a methodology to evaluate the region’s TDM programs. The Triangle J Council of Governments is a voluntary organization of municipal and county governments in North Carolina’s Region J (Chatham, Durham, Johnston, Lee, Moore, Orange and Wake Counties). The project has three broad objectives: 1) conduct an in-depth analysis to estimate the impacts of existing programs; 2) recommend TDM service enhancements; and 3) develop an evaluation methodology for TJCOG to estimate impacts of TDM programs in the future.

GDOT Measurement and Evaluation - Since 1999, CTE has led the Georgia Department of Transportation’s (GDOT) measurement and evaluation of TDM programs in the Atlanta region.  CTE along with a national team of TDM experts has provided recommendations to assist GDOT program managers and other TDM decision-makers in the region in making appropriate decisions for funding, program focus, and resource allocations. CTE’s expertise in the measurement and evaluation of TDM program sis nationally recognized and the GDOT evaluation program is an acknowledged leader in the practices of TDM evaluation, policy development, and implementation.

Past Projects

Missoula (Montana) in Motion - CTE was selected as part of a project team to provide TDM strategic planning, program evaluation, and assessment services to the Missoula in Motion TDM Project in Missoula, Montana. The work focused on inventorying and assessing program participation, performance, and progress and culminated in a 5-year strategic plan.

Implementing a Statewide Rideshare and Vanpool Program in Arizona - CTE assisted the Arizona Department of Transportation’s Transportation Research Center in investigating the potential for a statewide ridesharing and vanpool program for Arizona. The product of the research was an implementation plan that included key corridors, start-up considerations, staffing, and operational guidelines, as well as funding options for capitalizing the statewide program.

Association for Commuter Transportation - From June 2004 – June 2007, CTE provided management services to the Association for Commuter Transportation (ACT).    ACT is a growing, 850-member, association of organizations and individuals who share in the commitment to develop balanced, effective transportation systems around the country.  ACT’s primary mission is to reduce traffic congestion and improve air quality by encouraging the use of, and educating the public about, alternatives to solo commuting.  To that end, ACT provides its members with a wealth of information related to transportation demand management and serves as a clearinghouse for best practices in the field, as well as, the latest updates from current legislation.

Staff Qualifications

The GDOT continues to look to CTE and its national team of experts to provide guidance on TDM funding, program focus, and asset allocation based on the results from sound research and program effectiveness evaluations.  CTE’s TDM work is led by Wendy Morgan.

Ms. Morgan is a Senior Project Manager with CTE and provides key management support to the TDM research and measurement program being conducted on behalf of GDOT.  Wendy is also the co-coordinator of Clean Cities-Atlanta and is active on numerous community task forces related to TDM, alternative fuels, and strategic transportation planning in the metro Atlanta region. She holds a Bachelor’s degree in Politics and Sociology from Wake Forest University and a Master’s degree in Urban and Regional Planning from Virginia Tech.
