Intersection collision‑avoidance pilot draws interest for preventing T‑bone crashes
Summary
Consultants and district staff described ICAST — sensors and software that predict red‑signal violations and briefly extend an all‑red phase. The TPO board heard pilot results, learned the project expanded to 25 intersections with a $500,000 grant, and asked staff to include further study in future UPWP work.
Traffic engineers and TPO members spent the meeting’s middle session examining an intersection collision‑avoidance pilot that uses sensors and connected data to predict vehicles likely to violate red signals and briefly extend the all‑red phase.
Consultant Angelo Rao (Kittelson and Associates) described the predict‑verify‑extend‑resume approach and said early testing and laboratory review (TURL) validated the technique. The pilot began at four intersections and, after a state grant, expanded to 25; Rao said the project was awarded roughly $500,000 to scale…
