Abstract

In order to evaluate the impact of communication distance, vehicle speed and line-of-sight on the communication performance of CVIS (Cooperative Vehicle Infrastructure System) based on broadcast Wi-Fi, packet loss rate and communication delay are selected as representative indicators. Via constructing actual road traffic scenes divided into dynamic and static ones according to vehicle speed, and designing 4 test schemes under different communication distance and line-of-sight conditions, the OBU (On-board Unit) and RSU (Roadside Unit) are deployed in the closed test field to communicate with each other. The results show that communication distance and line-of-sight are obvious influencing factors of packet loss rate, but the speed has no great influence on the packet loss rate; the speed, communication distance and line-of-sight have little influence on the communication delay. It can be seen that communication distance and line-of-sight are the important factors that lead to the degradation of communication performance of CVIS.
