Installation of adaptive signal control technology (ASCT) at signalized intersections along the entire US RTE 1 corridor within the town of greenwich

The Federal Highway Administration (FHWA) awarded $190,926.77 to the Connecticut Department of Transportation under the Highway Planning and Construction program (CFDA 20.205) on August 18, 2025, for the installation of Adaptive Signal Control Technology (ASCT) at signalized intersections along the entire U.S. Route 1 corridor within the Town of Greenwich, Connecticut. The project is scheduled for completion by May 12, 2030, and represents a targeted transportation infrastructure improvement initiative focused on enhancing traffic flow and signal coordination in a critical regional corridor.

Under this formula grant award, the deliverable involves the deployment of adaptive signal control systems across multiple signalized intersections along the U.S. Route 1 corridor. ASCT represents an intelligent transportation system that dynamically adjusts traffic signal timing in real-time response to traffic conditions, improving overall corridor efficiency, reducing congestion, and enhancing safety. The Connecticut Department of Transportation, as the prime awardee and state transportation authority, is responsible for the design, procurement, installation, and implementation of this technology infrastructure throughout the designated corridor in Greenwich.
