This study examines the assistance system to predict driving behavior considering the pre-preceding vehicle information. The assistance system indicates an 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 several participants who follow a preceding vehicle and a visible pre-preceding vehicle. The participants with the assistance system succeeded in following the preceding vehicle with small acceleration and a small standard deviation of evaluation index of collision risk (Risk Perception), whereas the participants without the assistance system with large acceleration and a large standard deviation of evaluation index of collision risk.
