TAP provides funding for active transportation including biking, walking, safe and complete streets programs, and infrastructure.[3] SANDAG receives a direct allocation of funding from this program and allocates the funding regionally. This funding is matched with local, regional, and state funds to build out regional and local active transportation networks. Other sources that augment this funding include both the state’s Active Transportation Program (ATP), cap-and-trade program, and a small set-aside of TransNet funding.
