The purpose of the present study was to investigate the age difference in road crossing behavior. The participants were instructed to report whether they can cross the road(this road scene the other elements relating to road crossing were recorded previously and projected the simulation screen) after the leading vehicle passed them(i. e., before the target vehicle arrived). The participants' judgment accuracy and response bias were analyzed by using signal detection theory. The results showed that the old group tended to be less sensitive and more conservative in deciding road crossing. This tendency implies that the aged group's low sensitivity can be one of the major factors of their high accident rate in road-crossing situation.
