Improving the Maintenance of Signalized Intersections and Asset Management with Automated Traffic Signal Performance Measures

Webinar: Wednesday, April 25 at 1 pm EST

Register

There are more than 330,000 traffic signals operating in the United States, and highway agencies typically retime these signals on a three- to five-year cycle at a cost of approximately $4,500 per intersection. For the vast majority of these signals, citizen complaints are the primary measure of performance.

 

The FHWA’s Center for Accelerating Innovation promotes automated Traffic Signal Performance Measures (ATSPMs) as a way to improve on traditional timing processes and to reduce maintenance and monitoring costs.  The ATSPMs technology, a result of collaborative efforts between FHWA, AASHTO and a variety of DOTs and academic institutes, features a high-resolution data-logging capability, providing continuous performance monitoring. The data collected can then be used to identify and correct timing issues before they become complaints. Proactive timing and signal management also addresses congestion issues and improves safety at intersections.

During a webinar discussion on Wednesday, April 25 at 1pm EST, the FHWA and presenters from across the country will discuss examples of how ATSPMs are applied to improve the maintenance of traffic signal systems.
