Abstract


Vehicle-to-vehicle (V2V) communication technology has brought new developments for collision warning and avoidance system due to its broader environment information and perception range. Yet it also has limitations: packet loss, time delay and limited communication distance. This paper focuses on the effect of communication imperfections on collision warning and avoidance strategies. To better understand the avoidance behaviors, we propose two typical scenarios: vehicle following scenario and intersection scenario. In former scenario, a classical collision warning strategy, i.e., distance-base crash alert and avoidance algorithm is proposed; and in the latter scenario, a priority of vehicles using V2V communication is analyzed. Then the numerical experiments are carried out, which reveal the performance of warning and avoidance in different communication imperfections such as pack loss, time delay, limited communication distance. The results further demonstrate our model can be used to help avoid collisions and relieve traffic congestion.
