WASHINGTON, D.C. — The District Department of Transportation is expanding a smart traffic signal monitoring platform to more than 1,600 traffic signals across Washington, D.C., following a year-long pilot that tested the technology at more than 50 intersections.
DDOT said the Luminus signal performance platform will give engineers a broader view of how intersections are operating and help the agency make data-driven decisions about traffic signal timing. The agency selected Flow Labs to support the citywide deployment after the pilot demonstrated the value of using real-world traffic-condition data.
The expansion is aimed at improving transportation operations, safety, reliability and mobility for residents, commuters, businesses, visitors and government operations. DDOT said the platform will help staff monitor signal performance, collect operational data and identify locations where timing adjustments may improve traffic flow.
DDOT Director Sharon Kershbaum said the new probe-based signal performance measures add richer datasets and more varied performance measures to the agency’s existing signal timing work. The agency said engineers are expected to have access to performance measures at every signalized intersection in the District beginning in late June.
The rollout comes as DDOT continues investing in tools designed to manage changing travel patterns and prioritize signal retiming efforts across the city. Officials said the expanded monitoring capability should strengthen the agency’s ability to respond more efficiently as conditions shift across Washington’s transportation network.
