Transportation Demand Management

Alternative Congestion Relief (ACR) and Transportation Demand Management (TDM) are programs that promote transit and other forms of commuting to reduce the use of single occupancy vehicles.

One percent of all Measure A sales tax dollars are allocated for ACR programs and projects that encourage carpooling, ride-sharing and flexible work hours. Funds are also reserved for the planning and design of Intelligent Transportation Systems that facilitate more efficient use of existing highways and transit systems. This includes such things as highway ramp metering, signal priority for transit vehicles, and real-time travel information. Approximately $910,000 per year is generated from Measure A for these kinds of programs for a total of $15 million over the life of Measure A.

Additionally, with the adoption of the TA Strategic Plan 2020-2024, the Measure W Countywide Highway Congestion category included a set aside of four percent for TDM projects and programs that contribute to a reduction of vehicle miles travelled on the highway system. This equates to about one percent of all Measure W sales tax dollars for an additional $819,000 per year and a total of $24 million of the life of Measure W.

ACR/TDM Plan

The TA Strategic Plan 2020-2024 directed TA staff to initiate the development of an ACR/TDM Plan that would combine the goals and core principles of the Measure A and Measure W categories into one consolidated program. The ACR/TDM Plan was developed to guide investment decisions and funding allocations for the Measure A ACR Program and the TDM subcategory of the Measure W Countywide Highway Congestion Improvements program. The Plan provides a vision for the ACR/TDM program, program guidelines, example eligible projects/programs, and evaluation criteria for future Calls for Projects (CFP). The TA Board of Directors adopted the ACR/TDM Plan in January 2022.
