Automated Traffic Signal Performance Measures (ATSPM)

Automated Traffic Signal Performance Measures (ATSPMs) are tools that collect and analyze data on how well traffic signals are performing, such as how long vehicles wait or how smoothly they flow through intersections. By automatically monitoring these aspects, transportation agencies can identify issues and optimize signal timing to reduce delays, improve safety, and enhance traffic flow. Essentially, ATSPMs help make traffic signals smarter and more efficient, leading to better travel experiences and safer roads without requiring constant manual observation.
