Automated Traffic Signal Performance Measures: Management, Operation, and Maintenance 2026

  • May 20th, 2026

Automated Traffic Signal Performance Measures (ATSPMs) use high-resolution signal and detector data to enable continuous, proactive monitoring of traffic operations and maintenance. Although they have proven benefits, their adoption among state departments of transportation (DOTs) varies widely due to challenges such as funding, equipment upgrades, and staffing. Understanding the factors behind successful implementations and the […]

Evaluating the Safety Effects of Automated Traffic Signal Performance Measures 2026

  • May 20th, 2026

Automated traffic signal performance measures (ATSPMs) provide an alternative to traditional signal timing and have been shown to improve operations at signalized intersections by reducing split failures, arrivals on red, red-light running, and delays. Although not a fully adaptive solution, ATSPMs allow agencies to make near real-time signal timing adjustments based on field data, influencing […]
