DS Experiment on Driving Behavior at Switching Traffic Signals Focusing on Lamp Position

Abstract

There are studies focusing on the intersection structure and the presentation pattern concerning the safety and efficiency of the intersection, but there are few studies focused on the position of the signal lamp, few knowledge such as the difference in driving behavior due to the difference in lamp position. In this study, in order to obtain useful knowledge about differences in driving behavior, behavior judgment and driver's feeling due to the difference in position of the signal lamp, we analyzed the driving behavior date obtained by the DS experiment about the influence on driver’s behavior and judgment by the position of the signal lamp. The position of the signal lamp was experimented in the far-side of the intersection, mainly adopted in Japan and near-side of the intersection, mainly adopted in many foreign countries such as Germany. Based on the experimental results, differences were found in behavior judgment of passing and stopping, and reaction time at stop and start.
