Cooperative vehicle collision warning system using the vector-based approach with dedicated short range communication data transmission

There are three challenges that have to be overcome in order to enhance the accuracy of the cooperative collision warning (CCW) system. First, a vehicle does not always keep the same velocity. Second, the curve road condition should be considered. Third, position interruption caused by Global Positioning System positioning delay has to be tackled. In this study, the authors proposed a vector-based CCW system named VCCW to deal with these three challenges. The simulation results show that the proposed VCCW system has high accuracy's warning rates in both intersection and curve situations. The authors have also implemented the VCCW and tested the system on real roads. Through the VCCW system experiment on real roads, it shows that the VCCW system can alert drivers before collision.
