Abstract
Driving behaviors of vehicle on the subsidiary road at crossing were examined in terms of the road environments and traffic conditions. An actual driving experiment on the variable configuration crossing revealed that visual biases were induced to a visually obstructed direction and to a moving direction of own vehicle. Relatively high speed in approaching to the crossing were observed in the situations of visually open crossing and of less traffic volume on the crossroad. Another driving simulator experiment revealed the visual biases were tended to yield detection delays of crossing vehicle. And the detection delay and relatively high vehicle speed when the crossing vehicle became visible increased the collision risk in both visually obstructed crossing and open crossing.
