A Left Turn Assist Application using Wireless Vehicle-to-Vehicle Communications at Unsignalized Intersections

We present a wireless vehicle-to-vehicle communications-based safety application to assist drivers with safe left turns at unsignalized intersections. When a potentially dangerous situation such as an oncoming vehicle from the opposite lane is detected, our system can provide the driver with a warning. Our system gives advisory or imminent warnings according to the predicted accident levels through a HMI. For a performance test of our application, we configured three test scenarios and tested our system with vehicles on a proving ground. The test results showed 93% success rates.
