基于事故鉴定的信号控制路口电动自行车事故特征分析

电动自行车已成为群众出行的重要交通工具。随着电动自行车保有量的快速增长,涉及电动自行车的交通事故频发。为了研究电动自行车事故特征,特别是电动自行车违反交通信号灯控制的情况,基于涉及电动自行车的路口信号灯状态鉴定数据和事故数据,对事故的时间空间分布、碰撞车辆类型、骑车人个体特征、事故原因、电动自行车进入路口时信号灯状态等要素开展分析,获取了信号控制交叉口电动自行车事故特征规律,为开展此类事故预防提供参考。

Electric bike(E-bike)has become one of important traffic modes of the public.With the rapid growth of the number of E-bike ownership,traffic accidents involving E-bikes occur frequently.In order to study accident characteristics of the E-bike,especially traffic signal violation behaviors of the E-bike owner,the paper conducts an in-depth analysis of the temporal and spatial distribution of the accident,types of collision vehicles,the individual characteristics of E-bike riders,causes of the accident and the state of the traffic signal when the E-bike enters the intersection based on the traffic signal state identification data and accident data of traffic accidents involving E-bikes.The characteristics of E-bike accidents at signalized intersections are thus obtained,which can provide reference for the E-bike accident prevention.
