In Japan, the vehicle-cyclyist collisions at blind intersections account for approximately half of all traffic accidents, and the fatal accidents are more frequent at night than during the daytime. One technology that improves the visibility of vehicles at night is the use of road surface projection lamps. The purpose of this study is to investigate the effect of the road surface projection lamps on increasing the safety margin of cyclists in avoiding crashes at blind intersections. The methods of the study are based on (1) numerical simulation to calculate safety margins under assumed scenarios and (2) data analysis to calculate safety margins under events extracted from the near-miss incident database. The results s visualized the potential of the road surface projection lamps in increasing the safety margin of cyclists.
