Highway agencies typically rely on complaints or manual data collection to identify the need for signal retiming projects and their outcomes. These projects are typically scheduled on a 3- to 5-year cycle, at a cost of approximately $4,500 per intersection. The costs and effort associated with collecting performance data translates into congestion, reduced safety, and increased delays for vehicles, pedestrians, and bicyclists.
That’s where automated traffic signal performance measures come in. They will revolutionize the management of traffic signals by providing the high-resolution data needed to actively manage performance. High-quality service can be delivered to customers with significant cost savings to agency maintenance and operations. A number of implementation options are available, ranging from a low-cost, open-source code framework to a fully integrated traffic signal system.
This breakout session on Automated Traffic Signal Performance Measures (ATSPMs) was recorded at the Federal Highway Administration’s Every Day Counts (EDC) Regional Summits in the fall of 2016. The Summits provided transportation professionals the opportunity to learn about the 11 innovations promoted through EDC-4, exchange ideas with their agency and industry counterparts in neighboring States, and provide feedback to FHWA on the support and resources needed to adopt the innovations in their own States.
