Abstract
The methodology for evaluating the effectiveness of information presentation regarding oncoming vehicles at intersection in terms of the reduction of traffic accidents was proposed. At first, driver's behavior such as the relation between the distance to an oncoming vehicle and the frequency of right-turning at intersection was analyzed, when the field of view was changed and the information system presenting the distance to an oncoming vehicle was used or not, in a driving simulator with 50 participants. After that, the driver's operation model simulating the right turning at the intersection based on the driver's behavior analyzed in the experiment was coustructed. The frequency of collision at the intersection was analyzed through 10,000 times of simulations at each condition by making use of this driver's operation model. One of the results show that the frequency of the collisin was decreased from 6.1×10-3 to 1.0×10-6 in condition that the field of view is extremely short such as 40m at the intersection when the driver used the information system for avoiding the collision.
