Automated Traffic Signal Performance Measures (ATSPM) (UPC 124131)

The City of Richmond is accepting bids from qualified traffic signal contractors to provide general contracting services for the Automated Traffic Signal Performance Measures (ATSPM) Project (UPC 124131). The work includes, but is not limited to, the installation of vehicle detection systems; traffic signal cabinets and controllers; electrical conduits; conductor cables; and junction and pull boxes.

Automated Traffic Signal Performance Measures (ATSPM) is a data-driven system used to monitor and improve traffic signal operations through continuous, high-resolution signal and vehicle detection data. ATSPM enables transportation agencies to proactively identify operational issues, optimize signal timing, and improve corridor performance without relying solely on field observations or citizen complaints.

Implementation of ATSPM supports the City’s Vision Zero goals by improving traffic signal reliability, reducing congestion and delay, and enhancing safety for all roadway users. The system provides objective performance metrics that support data-based decision-making, efficient maintenance, and transparent reporting of traffic signal performance.
