Regarding the safety and efficiency of intersections, there are studies focusing on intersection structures and display patterns, but there are few studies focusing on the position of signal lamps, and sufficient knowledge of differences in driving behavior due to differences in lamp positions have not been obtained. Therefore, in this study, focusing on the position of the signal lamp, driving performance differences between the right front and far left (far type), which is mainstream intersections in Japan, and the left front (near type), which is mainstream intersections in Germany etc. Evaluation was made using driving behavior data obtained by experiments using a driving simulator. As indicators for evaluating intersection performance, “passage judgment rate and collision possibility“ and “crossing time difference“ are used for safety, and “traffic capacity at intersection“ is used for efficiency. As a result, it was shown that near type intersection might have higher performance in both safety and efficiency than far type one.
