The Relationship between Signal Light Positions and Vehicle Behavior at Intersections under Various Signal Controls

Abstract

In order to realize a smooth and safe intersection, the position of the signal light is an essential factor. Changing the position of the signal light (far type and near type) may affect driving behavior before and after passing through an intersection, such as automatic driving and signal control at intersections. However, the knowledge of the analysis considering the position of the signal lamp for various signal controls has not been sufficiently obtained. Therefore, in this study, we used data from a simulated driving experiment using a driving simulator to analyze vehicle behavior when changing signal control under conditions in which signal lamp positions were compared. Some of the signal controls of the far type tend to lead to driving behavior that increases the danger. In contrast, the proportion of driving behaviors that increase the danger of the near type is lower than that of the far type in all signal controls. The characteristics of driving behavior associated with the difference in signal lamp position were clarified.
