Transportation Demand Management (TDM) Action Plan

TDM graphic - turn car congestion into transit, walking, biking and carpooling


The TDM Action Plan will take a strategic, data driven look at our existing TDM Programs and explore new opportunities (including programs, incentives, policies and price signals) to determine the most effective TDM levers. The end result will be a plan outlining recommended next steps and priorities for our TDM work that best help move the needle toward our mobility, equity and climate goals. 

Why do a TDM Action Plan?

The City of Portland has several adopted goals related to reducing the number of drive-alone trips on our roads, which negatively impact our climate, health and community. To date, PBOT has developed a number of programs (such as SmartTrips, the Transportation Wallet, Sunday Parkways and Safe Routes to School) that aim to help manage demand for our roadways and increase use of active transportation options. While many of these programs are popular and have a positive impact, we need to take a strategic look at which transportation demand management (TDM) strategies are most effective at reaching our mobility, equity and climate goals and best serve the needs of our community.
