TDM Expertise ∙ Commute Planning

As a leading provider of transportation and planning services, TransAction Associates develops and implements Transportation Demand Management (TDM) services.

Our TDM group has expertise in commuter assistance programs in major markets throughout the country. We have proven success executing a range of work-site strategies designed to reduce vehicle miles traveled and improve air quality.


What is TDM?

Transportation Demand Management (TDM) is the flip side of infrastructure. Also known as Mobility Management, it includes various strategies that increase transportation system efficiency. TDM treats mobility as a means to an end, rather than an end in itself. It focuses on helping people use the infrastructure in place for transit, ridesharing, walking, biking, and telework. It is cost-effective in guiding the design of our transportation and physical infrastructure, so that alternatives to driving are naturally encouraged and our systems are better balanced.

TDM is a program of information, encouragement and incentives provided by organizations to help people know about and use all of their transportation options in order to optimize all modes in the system – and to counterbalance the incentives to drive that are so prevalent in subsidies of parking and roads. These are both traditional and innovative technology-based services to help people use alternatives.

TDM is also a general term for strategies that increase overall system efficiency by encouraging a shift from single-occupant vehicle (SOV) trips to non-SOV modes, or shifting auto trips out of peak periods. TDM seeks to reduce auto trips and vehicle miles traveled by increasing travel options, and by providing incentives and information that encourage and help individuals modify their travel behavior. The impact of a comprehensive set of TDM strategies can have a significant impact on travel behavior, system efficiency and SOV rates.

Our services examine all aspects of alternative transportation. Our team members work with public and private-sector employers to implement outreach and marketing-related services.

This includes:

  • Acting as liaison between companies, communities and stakeholders
  • Creating operational processes at building sites for reducing commuter trips
  • Designing and selecting methods for commute-related data collection
  • Analyzing data, and providing tracking and evaluation mechanisms
  • Reviewing processes and recommendations

TransAction Associates provides TDM-related services that range from long-term behavioral / change incentives, to the promotion of trial usage and the reporting of commuter behavior. Tactically, we implement direct-to-commuter worksite activities that cross-promote a range of services, including on-site employer-based training services and events that reward and promote individual success.
