Project Description

The Bus Queue Jump Signal pilot proposal includes the design and installation of a pilot set of queue jump signals. This innovative project will expand on existing “smart intersection” technology to grant CTA buses early signal priority, allowing them to safely bypass traffic at intersections. Partnering with CTA on this project is the Chicago Department of Transportation (CDOT) and they have been implementing smart intersection technology throughout the city, which utilizes video detection to assess roadway usage and provide traffic counts, among other uses. This existing technology will be built upon, using components of machine learning, to identify CTA buses and communicate with the signal controller to provide a bus queue jump signal on a separate signal head. Through precisely targeting CTA buses, priority signals will only be granted when needed, ensuring an efficient use of signal time at the intersection.
