Abstract

The present study summarizes the features of the central and peripheral vision of elderly pedestrians who are judging when it is safe to cross the road in front of an approaching car. For the pedestrian's central visual field, we investigated the effect of age on the timing judgment using an actual car. The results for daytime conditions indicate that the elderly pedestrians tended to make later judgments of when they crossed the road from the right side of the driver's view at high car velocities. At night, for a car with its headlights on high beam, the average car-pedestrian distances of elderly pedestrians on the left side of the driver's view were significantly longer than those of young pedestrians at velocities of 20 and 40 km/h. Cars with their headlights on highlights could be an effective countermeasure to keep the safety car-pedestrian distances of elderly pedestrians. When we focused on the eyesight of elderly pedestrians, the eyesight did not affect the timing judgment of crossing a road during the day. At night, for a car with its headlights on either high or low beam, the average car-pedestrian distances of elderly pedestrians having good eyesight were longer than those of elderly pedestrians having poor eyesight, for all car velocities. To correct the poor eyesight with glasses could also be an effective countermeasure for elderly pedestrians to keep safety car-pedestrian distances. The car-body color in the elderly pedestrian's peripheral vision affected the pedestrian's awareness of the car.
