An Analysis of Collision Avoidance Effectiveness by Using the Information Displayed in Driver's Peripheral Vision

摘要

A collision avoidance system has a potential to reduce traffic accidents and expected to become widely used. From the driver's point of view, it is important to present a collision warning which does not disturb driver's concentration on driving. This paper describes the effectiveness of the collision avoidance system which uses the information displayed in driver's peripheral vision (peripheral vision information) in right turn at an intersection. In order to analyze the effectiveness of the peripheral vision information, the authors evaluated a response time to the information and an effect of over-trust behavior when the information was not presented. The analysis was conducted through a driving simulator experiment and the result showed that the peripheral vision information is effective to avoid a collision. Moreover, the over-trust behavior, the delay time of a response time when the information is not presented was reduced.
