Abstract
In late years, a problem of a traffic jam becomes a beginning social problem by increase of traffic volume on a town area and a highway. Technical introduction of ITS is expected to solve this problem. This study examines speed control algorithm of a vehicle in the traffic flow simulation that tracks mixes with cars aiming at increase of traffic volume. And in consideration of a human characteristic, we examine the influence that automatic driving and driving to be worked by hand give to traffic flow.
