Evaluations of traffic safety improvement using an autonomous traffic flow simulator including inter-vehicle communications

In ITS (intelligent transport systems), it is very important to evaluate the effectiveness of inter-vehicle communication systems. Unfortunately, few studies on traffic flow simulators that can evaluate the effectiveness of inter-vehicle communication systems for improving the traffic safety have been reported. In this paper, we evaluate the effectiveness of inter-vehicle communication systems using the traffic flow simulator including inter-vehicle communications developed by the authors. Simulation results show that the inter-vehicle communication system is effective in improving the traffic safety
