Abstract The cooperative driving system is a typical vehicular cyber-physical system, and it can integrate the vehicular cyber system with the vehicular physical system for the optimization of the cooperative driving at traffic intersections. The use of Vehicle-to-Everything (V2X) enables moving vehicles to communicate with each other, share Emergency Warning Messages (EWM) and provide drivers with pre-collision warnings in the vicinity of the intersection. Although Vehicle Ad Hoc Networks (VANET) can provide the access to vehicular cooperative driving systems, EWM transmission delay, error and redundancy often happen in the vicinity of traffic intersection. In order to improve the quality of the EWM propagation, this paper proposes an Optimal Transmission Reliability Enhancement Mechanism (OTREM) for the development of the cooperative driving systems. Our OTREM creates the strategy of the vehicular role change using the modified finite automata as the solution to the above EWM transmission problems. The experimental analyses show the proposed approach can significantly decline transmission delays, improve propagation accuracy, lessen EWM redundancy and raise propagation rates of EWM.
