Adam Lyons of Iteris
By aggregating the count data at intersections and utilising sophisticated algorithms for analysis, Iteris’ system provides speed, flow, and occupancy data for turning movement on the main corridors. Algorithms make short-term flow predictions to set signal timing reflecting current conditions, instead of conditions from five or 10 minutes earlier. These improved data inputs feed into the county’s central traffic control system to identify which intersections’ cycle times need adjusting to improve traffic flow.
Iteris will also be highlighting its involvement in the design and integration of the San Mateo Smart Corridor system along Highway 101. A combination of arterial message signs, improved broadband communications, and updated detection, ensures that when issues occur on the 101 traffic is properly diverted onto arterials to maximise throughput and relieve congestion quickly.
Another recent ITS activity in the Bay Area is the build-out of Traffic Management Centers (TMC) to actively manage traffic flow. Iteris is at the forefront of this activity, from TMC design and installation to providing world-class detection systems that provide live-video to operators. The company points out that live-video is more powerful today as operators rely on accurate detection and want to see what is happening in real-time. Iteris built the city of Santa Clara’s TMC in time for the recent Super Bowl, helping City engineers not only better manage daily traffic, but also during special events.
