汽车VS二轮车十字路口事故场景研究

为研究十字路口发生的汽车与二轮车事故场景,基于NAIS事故数据库中发生在十字路口的汽车与二轮车事故数据开展研究。选择描述十字路口事故关键参数,依据事故发生时环境照明、十字路口信号灯、汽车所在道路车道数、道路限速、汽车种类、汽车速度、汽车运动方式、第一碰撞点、二轮车种类、二轮车运动方式等参数,对事故数据进行聚类分析,得到5类主要危险场景。基于发生频率最大和骑车人死亡风险最高的场景具有危险场景代表性,最终得到2类十字路口汽车与二轮车的典型事故场景。为十字路口汽车与二轮车的冲突消解、避撞策略研究提供参考。

Study on the Crossroad Accident Scene of Automobile VS Two-wheeler

In order to study the scenes of car and two-wheeler accidents that occurred at intersections,we conducted research based on the data of car and two-wheeler accidents that occurred at intersections in the NAIS accident database.Select the key parameters describing the intersection accident,according to the ambient lighting at the time of the accident,the intersection signal lights,the number of road lanes where the car is located,the speed limit of the road,the type of car,the speed of the car,the way of car movement,the first collision point,the type of two-wheeled vehicle,and its way of movement.According to the parameters such as the movement mode of the wheeled vehicle,the cluster analysis of the accident data can obtain 5 types of maindangerous scenes.Based on the scenes with the highest frequency and the highest risk of cyclists'death,which are representative of dangerous scenes,two types of typical accident scenes of crossroad cars and two-wheeled vehicles are finally obtained.It provides a reference for the conflict resolution and collision avoidance strategy research of crossroadaccidents.
