Transportation Demand Management

TDM Planning Resources

SANDAG offers guidance to local jurisdictions, mobility operators, and the development community on effective transportation demand management (TDM) policy and strategy implementation.

Mobility Management Toolbox (2019)

SANDAG developed a Mobility Management Toolbox to help jurisdictions and developers evaluate the potential benefits both TDM and Transportation System Management (TSM) measures have on reducing vehicle miles traveled. Toolbox resources include a mobility management guidebook, VMT reduction calculator tool, implementation guidance, and more.

San Diego and Western Riverside Interregional Park & Ride Strategy (2019)

SANDAG partnered with the Riverside County Transportation Commission (RCTC) to develop an interregional strategy to improve the management and planning of Park & Ride facilities. The strategy includes the development of a GIS data center that houses Park & Ride data for both regions, identifies tools for improving existing and future facilities, and proposes regional recommendations for public agencies to consider.

Regional Parking Management Toolbox (2014)

SANDAG developed the Regional Parking Management Toolbox to provide communities within the San Diego region with a framework for evaluating, implementing, and managing parking management strategies that support their economic development, sustainability, and mobility goals.

In 2020, the Toolbox will be updated to account for more flexible curb space strategies that may be considered as newer mobility services and technologies emerge. Staff will also update the local parking inventory and assess how cities plan to leverage technology to solve parking challenges.
