Comparative analysis of vehicle behavior for different signal lamp positions at complex intersection

Abstract

In this study, vehicle behavior at intersections with more complex geometric structures than crossroads was analyzed by simulated driving experiments using a driving simulator (DS) to compare the behavior of vehicles in response to different signal light positions and to obtain knowledge for studying appropriate light positions. In conclusion, under conditions of risk of rear-end collisions at complex intersections, the near type had a higher passing decision rate than the far type when the signal was switched, the near type stopped farther from the stop line than the far type in the analysis of stopping positions, and the near type stopped farther from the stop line than the far type at some complex intersections. In the analysis of stopping positions, the near type stopped farther from the stop line than the far type. Thus, the results suggest that the near type has improved safety more than the far type, and this was more pronounced at complex intersections.
