Authors conduct a survey of the elderly on items including lifestyle, behavioral pattern, and walking speed for preventing traffic accidents involving elderly pedestrians crossing a road. The result shows that the elderly often cross a low-traffic volume road they are familiar with in their neighborhoods, which does not have a crossroad. We also investigate the pedestrian-to-vehicle distance which makes a pedestrian give up crossing a road on a two-lane course in a driving school. As a result, it is found that the pedestrian-to-vehicle distance is longer when a vehicle is approaching from the pedestrian's left than from his or her right, and the pedestrian-to-vehicle distance increases as the vehicle speed increases/Also, when a vehicle speed is 40km/h or higher, the time taken for a vehicle to reach a pedestrian is shorter than the time taken for a pedestrian to cross a 7m-width road. Therefore, the vehicle approaching from the left may collide with the pedestrian. It is suggested that enhanced countermeasures against pedestrians on the right side with respect to vehicles are important.
