Abstract

In these years, a problem of traffic congestion is a growing concern due to increasing vehicle holders in urban areas. One of key issues to ease the traffic congestion is a traffic signal control. In this paper, we propose a control system for traffic signals by a vehicle route sharing. The vehicle route sharing is to share position and path information (i.e., probe data) among vehicles. The shared information is used for calculating a criteria of traffic congestion called expected traffic congestion. The parameters of traffic signals (i.e., cycle, split, and offset) are optimized on the basis of the expected traffic congestion. We performed a multiagent simulation to evaluate the effectiveness of our proposed system. The results show that our proposed method can ease traffic congestion effectively compared with other traditional methods.
