Abstract(in English) V2V broadcast communication is not only promising for safety driving assistance but also enhancing automated driving ability by sharing information of vehicle moving behavior with other vehicles. However, an important issue is how to reduce information delivery delay and achieve highly reliable communication that is essential for automated vehicle control by machine. Although repeated transmission method can enhance reliability of broadcast transmission, information delivery delay significantly increases as packet delivery rate (PDR) decreases. In order to improve the PDR of V2V communications, relay-assisted V2V schemes have been proposed. In this paper, information delivery delay of the relay-assisted scheme is analyzed. Then performance with roadside relay stations considering urban environment with multiple intersections and more than 1100 vehicles is evaluated through large-scale network simulation. The obtained results show that the average delivery delay is remarkably reduced by the relay-assist scheme to less than 20 ms, which is less than a quarter of the direct V2V communication.
