This study examines driver's following characteristics with the past two vehicles immediately ahead, i.e. a preceding vehicle and a pre-preceding vehicle. Driving simulator experiments are examined with five participants who are required to follow the preceding vehicle with/without the pre-preceding vehicle which the driver can observe directly. The multiple regression analysis is applied to identify which information the driver uses to follow the vehicles. Experimental results show that the participants follow the preceding vehicle with information not only on the following vehicle but also on the pre-preceding vehicle, and the pre-preceding vehicle information suppresses unnecessary acceleration.
