Abstract
This study examines the assistance system to predict driving behavior considering the pre-preceding vehicle information. The assistance system indicates the evaluation index considering not only the relation (Time HeadWay) between the preceding and following vehicles, but also the relation (Time To Collision) between the pre-preceding and following vehicle. Driving simulator experiments are examined with two participants who follow the preceding vehicle follows the visible pre-preceding vehicle. The participants with the assistance system make it possible to follow the preceding vehicle with a small relative velocity to the pre-preceding vehicle, while the participants without the assistance system with a large relative velocity to the pre-preceding vehicle.
