The Effect of Moving Light Guide System in Traffic Jam focused on Acceleration Behaviors

Abstract

As one countermeasure for traffic congestion in the sag section, for the purpose of promoting suppression of speed reduction and early recovery of traffic jams, "the moving light guide system" is set up on expressways all over Japan. However, regarding the moving light guide system, there are not many studies on light emission conditions to increase the effect of increasing traffic capacity during congestion. About the moving light guide system, we conducted a comparative experiment of driving behavior using a driving simulator by changing the lighting condition, light emitter shape and brightness of the light emitter. The purpose of this experiment is to obtain knowledge about the light emission conditions for further improving the effect of increasing the traffic capacity by the moving light guide system. As a result, it was confirmed that the moving light guide system clearly had the effect of increasing the traffic capacity. Furthermore, it was suggested about the effect difference of changing the shape and brightness of the light emitter.
