Program Overview

Often, the most cost-effective way to solve a problem related to transportation is to manage demand. Transportation demand management (TDM) focuses on helping people change their travel behavior—to meet their travel needs by using different modes, traveling at different times, making fewer trips or shorter trips, or taking different routes. Through the nation’s largest and most comprehensive TDM research program, CUTR’s diverse research portfolio ranges from guidance for integrating TDM into the transportation planning process to developing the TRIMMS(tm) tool for estimating impact of TDM to developing patented technologies for global positioning system-enabled mobile phones to track travel behavior. Our technical assistance efforts include managing Best Workplaces for Commuters, which recognizes and supports employer-provided transportation services; operating the Florida TDM Clearinghouse and the National TDM and Telework Clearinghouse, including its online support center; producing netconferences; administering a 2,550+ member TRANSP-TDM listserv to foster peer-to-peer exchanges; advancing safety by conducting targeted bicycle and pedestrian safety educational outreach programs to community groups; facilitating Safe Routes to Schools; and offering a nationally recognized Commuter Choice Certificate and Social Marketing in Transportation Certificate training programs.

Philip L. Winters is Director, Transportation Demand Management (TDM) Program at the Center for Urban Transportation Research (CUTR) at the University of South Florida (USF). He has nearly 40 years in influencing the intensity, timing and spatial distribution of vehicle demand for the purpose of reducing the impact of traffic, managing parking needs, reducing greenhouse gasses, and enhancing mobility options. His team of six full-time researchers have extensive list of projects from developing tools for influencing travel behavior to predicting impacts of TDM to providing guidance on incorporating TDM into the land development process to creating patented software to track travel behavior on mobile devices. To facilitate the transfer of this knowledge, he established Commuter Choice Certificate, the country’s most comprehensive and longest running TDM-related training program. In partnership with USF College of Health, he also introduced Social Marketing in Transportation Certificate to help transportation professionals across the country create local programs designed to affect travel behavior. He created the leading industry listserv in 1998 that now has about 2,000 active members. Mr. Winters is a co-inventor on 16 patents. He is an emeritus member of the Committee on TDM of the Transportation Research Board. He also received the prestigious Association for Commuter Transportation’s Bob Owens TDM Champion Award in 2007. Mr. Winters received a B.S. in civil engineering from Virginia Tech.
