Abstract
Aim of the present study is to obtain basic knowledge on lateral control in winter driving environment. We measured the displacement from the lane center position from the road frontal image recorded by on-board video camera. Also, influencing factors on the lateral deviation, such as road alignment, were analyzed. The results of the measurement revealed that the lateral deviation of the vehicle pass to the shoulder side is large in the winter driving environment. In particular, the lateral deviation to the shoulder side was greater in curved sections than in straight sections. It is supposed that the drivers’ fear of passing an oncoming vehicle may affect the lateral deviation of the travel track. It is desirable to be able to perform lateral control of traveling on snow trajectories where the paved road surface is exposed.
