Portable Tool for Periodic Evaluations of Intersection Signal Timings
The safety and efficiency of traffic-signal-controlled intersections rely on having appropriate timing signals for intersection users. Yellow, all-red, and crosswalk timings that are too low for users create the potential for intersection conflicts. Similarly, effective green times that are too small for volumes create long queues and congestion. However, signal timings are typically only evaluated every 2-5 years when signals are retimed through an often time-consuming process. The proposed solution is a portable device containing low-cost off-the-shelf radar and camera sensors that will record the trajectories of intersection users differentiating between pedestrians, bicycles and vehicles.
