The premier organization for TDM professionals


ACT’s Certification Program for TDM Professionals

The Association for Commuter Transportation has established a national certification program for Transportation Demand Management (TDM) professionals. This program supports the continuing education and professional development that enhances the knowledge and performance of local, state, federal, private-sector and non-profit TDM professionals.
The role of the TDM professional continues to expand with increased congestion in urban cores, mobility challenges in rural and developing regions, the growth of new business districts, shifting commuter patterns, demand for convenience, the development of technologies that have created more mobility options, and now in response to an recovery planning related to the COVID-19 pandemic.  This certification program lays the foundation for ensuring that highly qualified individuals are available to meet the challenge of addressing the diverse needs of commuters, communities, and employers.
A list of current Transportation Demand Management Certified Professionals (TDM-CP) can be found here.


The purpose of the TDM Certified Professional (TDM-CP) program is to:

  • Recognize and provide an incentive for individuals to continually improve their knowledge of TDM concepts, policies, and practices;
  • Enhance individual professional development goals and skills;
  • Promote continuing education of relevant subject matter that is evidence-based; and
  • Demonstrate a TDM professional’s competency by developing a standard for assessment and measurement of knowledge by and through formal examination.
