Communications and Radar-Supported Transportation Operations and Planning (CAR-STOP)

What Was the Need?

A recent NHTSA report indicates that more than 80% of all annual car crashes could be prevented by vehicular communications. To that end, the focus of this project was to develop a framework conceptualizations, processes, procedures, and algorithms) to harness and mature wireless technology to improve transportation safety, with an emphasis on collision warning/collision avoidance (CW/CA) systems.

What's the Solution?

Simulation settings used in this research appear to reinforce the notion that substantial traffic safety improvement is attainable though the use of automotive communication technologies, but also suggest this goal is likely achievable only through use of combination systems (e.g., of radar/camera sensing and V2V communications). The new frameworks for integrated CW/CA systems incorporating information from both radar and communication will help prevent collisions. The developed joint millimeter communication and radar systems will seamlessly combine the communication and radar benefits to create a platform for sharing a multitude of sensor data.

Research Benefits

Accidents involving non-motorized traffic participants (pedestrians and bicyclists) can be prevented by sharing raw sensor data (e.g., camera live images) among vehicles. Millimeter wave vehicular communication with high data rates will enable raw sensor data sharing.
