G1810103 信号なし交差点における歩行者事故防止のためのドライバから歩行者への意思伝達支援の研究([G181-01]交通事故の予防)

Abstract

Recently, the percentage of a number of pedestrian fatalities to that of road traffic fatalities is the most in Japan. It is pointed out that these accidents are deeply related to the mismatch of recognition on traffic situation between pedestrians and vehicle drivers. Although many on-board devices designed to prevent injury or accidents are developed, there are few devices providing mutual understanding between pedestrians and vehicle drivers. In this paper, we studied attentive actions of pedestrians to vehicle on intersection with no traffic lights in order to design the systems providing the information about the vehicle condition (e.g., running direction, speed) from vehicles to pedestrians. We measured a gaze point of pedestrians who intend to cross a road. The positions of the gaze point on the approaching vehicle were determined by the panels attached to several places on the vehicle (e.g., an engine hood, a windshield). On these panels a random combination of a number and an alphabet is written. In the experiment, participants were required to answer the panel that they looked at in the fixed time (1 [s]). From the measurements, we found that the panels attached to an emblem and an engine hood were looked at with high frequency regardless of individual difference. Furthermore, the position of gaze points moved from the inside to the outside of the front of the approaching vehicle.
