What is TDM?

Transportation Demand Management (TDM) means the use of strategies to inform and encourage travelers to maximize the efficiency of a transportation system leading to improved mobility, reduced congestion, and lower vehicle emissions.

Real Options for Commuters
Transportation Demand Management programs and policies aim to provide commuters with a mix of reliable and affordable transportation options. Supported with effective marketing and advanced technologies, commuters can make informed choices to meet each trips unique needs, while considering cost, time, and convenience.

Reduced Traffic Congestion
With even a small reduction in the number of single occupancy vehicles on our nation’s roads, commuters can see significant reductions in congestion. TDM supports the most efficient use of our existing infrastructure by increasing per person throughput and allowing more people to use our infrastructure.

Improved Public Health and Safety
With reduced reliance on personal vehicles, our communities will see cleaner air leading to direct improvements in public health. TDM initiatives that support increased levels of walking and cycling also enhance overall quality of life; and more people on our streets and sidewalks will create safer neighborhoods.

Connecting People to Jobs & Supporting Economic Activity
With more commuting options and less traffic, people will have better and more reliable access to jobs. Businesses will see increased productivity from employees who spend less time stuck in traffic; and products will move quicker to market.
