The Real-Time Signal Timing and Traffic Information Project (Tucson Bluetooth Systems Deployment)

Our team developed a low-cost Bluetooth-based travel-time sensors project. More than 50 Bluetooth-based sensors are installed in Tucson to monitor real-time travel time on five major arterials. In this project, traffic signal timing on Speedway Blvd was examined and improved using real-time signal timing data collected from MaxviewTM, probe vehicle data and video sensor data.
