Description
The Traffic Signal Modernization Program (TSMP) is a grant initiative by the Tennessee Department of Transportation (TDOT) aimed at helping communities and local traffic-signal agencies update and modernize existing traffic signal equipment and operations. The program’s goal is to enhance traffic management, safety, and efficiency at state route intersections by providing funding for targeted upgrades, including new controllers, signal heads, detection systems, pedestrian signals, and signal timing optimization. All awarded projects must align with state and federal requirements, and TDOT staff or on-call consultants will handle all design services.
