Effect of using route information sharing to reduce traffic congestion

In this research, our aim is to increase the utility of road transportation systems by reducing traffic congestion for the benefit of both individuals and society as a whole. To attain our purpose, we propose a simple route guidance mechanism based on mass user support. Through multiagent simulation, we examine the ability of our proposed mechanism for improving traffic efficiency of both individual drivers and whole systems. Our simulation results that i) our proposed mechanism improves efficiency for the drivers who use it and the entire transportation system, and ii) the social dilemmas in route choice behaviors occur in a radial and ring network.
