Transportation Demand Management or Travel Demand Management (both TDM) is the application of strategies and policies to reduce travel demand (specifically that of single-occupancy private vehicles), or to redistribute this demand in space or in time.

In transportation, as in any network, managing demand can be a cost-effective alternative to increasing capacity. A demand management approach to transportation also has the potential to deliver better environmental outcomes, improved public health, stronger communities, and more prosperous and livable cities. The techniques of TDM, applied by government transportation agencies, link with and supports community movements for sustainable transportation.

There is a broad range of TDM measures, including:

• Transportation Management Associations: leverage public and private funds to increase the use of ridesharing and other commuting options that reduce traffic congestion and improve air quality
  
  
• Including or improving pedestrian-oriented design elements, such as short pedestrian crossings, wide sidewalks, and street trees

• Requiring users of parking to pay the costs directly, as opposed to sharing the costs indirectly with others through increased rents and tax subsidies

• Including and improving public transportation infrastructure, such as bus stops and routes

• Subsidizing transit costs for employees or residents

• Bicycle-friendly facilities and environments, including secure bike storage areas

• Providing active transportation facilities including bike lanes and multi-use trails

• Flex-time work schedules with employers to reduce congestion at peak times

• Workplace travel plans

• Roadspace reallocation, aiming to re-balance provision between private cars which often predominate due to high spatial allocations for roadside parking, and for sustainable modes

• Time, Distance and Place (TDP) Road Pricing, where road users are charged based on when, where, and how much they drive. Some transportation experts believe TDP pricing is an integral part of the next generation in transportation demand management
