Automated traffic signal performance measures (ATSPMs) are a promising tool for improving operations at signalized intersections, yet their implementation and use vary widely among agencies. Understanding current practices and lessons learned can help agencies overcome barriers and expand the effective use of these tools. TRB hosted a webinar on Tuesday, June 30, 2026 from 12:00 PM to 1:30 PM Eastern that discussed the practices for traditional and crowd-sourced ATSPMs, present case examples from five state DOTs, and highlight recommendations for future research. It explored different use cases, common challenges, and the factors that have contributed to successful ATSPM deployments. Attendees gained insight into barriers that have limited broader adoption and practical strategies to address them, as well as a clearer understanding of how ATSPMs are being applied across the United States.
This webinar was based on NCHRP Synthesis 659: Automated Traffic Signal Performance Measures: Management, Operation, and Maintenance.
This webinar was sponsored by TRB’s National Cooperative Highway Research Program.
The slides are available.

Learning Objectives
At the end of this webinar, participants can:

• Explain current practices for traditional ATSMs (i.e., high-resolution controller and detector data) and crowdsources ATSPMs (e.g., probe vehicles, connected vehicles) in the United States
• Identify barriers that prevented ATSPM expansions and factors that led to successful deployments
