Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we performed examination for the realization of the communication between a traffic light and the vehicle. First, we measured radiation angle characteristics of the traffic light and incident angle characteristics of the receiving apparatus. Based on the result, we calculated a reception strength distribution characteristic on the communication. Then, we constructed a pedestrian support system for the visually impaired that uses visible light communication (VLC) from self-illuminating bollards. To achieve this goal, we conducted a visibility evaluation using pedestrians with low and normal vision to determine the best bollard lighting pattern for pedestrian navigation systems. Moreover, we constructed a sidewalk model to evaluate the navigation system, and the communication area of the system was experimentally determined. We then created a prototype of the navigation system using VLC. The prototype was evaluated by visually impaired users, clarifying the effectiveness of the system.
