基于汽车-行人碰撞的安全车速模型研究

在混合交通的复杂路况下,汽车与过街行人很容易发生碰撞,本研究分析了行人过街的危险度,并且针对行人从自车前方相邻车道慢速行驶的机动车前面突然出现横穿公路并与自车发生碰撞的类型,分析了自车、慢速前行的机动车和行人的运动与驾驶员的视线之间的相互关系,建立了汽车安全车速的计算模型,从而为驾驶员安全行车提供参考.

Study on Safe Driving Speed Model Based on Vehicle to Pedestrian Collision

Vehicles are very prone to collide with pedestrians who are crossing the street under the circumstance of the mixed traffic. Risk of pedestrians＇ crossing is analyzed in the study ,and the relationship between the movements of the subject vehicle, the motor vehicle which is moving slower and the pedestrian, and the driver＇s line of sight is analyzed according to the collision type that a pedestrian suddenly appears from front a motor vehicle which is moving more slower than the subject vehicle in the front of the adjacent lane, crosses the road and then collides with the subject vehicle. A method to calculate the safe driving speed to avoid collision is proposed, so that a reference for safe driving could be provided.
