非机动车交通事故统计分析及仿真研究

Simulation research and statistical analysis of non-motor vehicle traffic accidents

通过统计天津市近3年181起非机动车骑行推行交通事故典型案例,分析了骑行推行交通事故中碰撞类型、特征痕迹分布、机动车和非机动车类型与痕迹位置分布、骑车人性别及损伤分级等数据分布规律。运用PcCrash软件,再现了一起典型的乘用车与自行车交通事故。通过对事故过程中骑车人的受力及加速度分析,验证了事故发生时自行车的行驶状态,总结了人体伤痕的分布和非机动车车体痕迹分布的特点。

According to the statistics of 181 traffic accidents of riding and implementation of non-motor vehicle of Tianjin in the last three years, the collision type, the distribution characteristics of trace＇ type of motor vehicles and non-motor vehicles, rider＇s gender and injury classification are analyzed. With a passenger car and bike accident cases as the research object, the Pc-Crash software is used to reconstruct the accident process. The analysis of the force and acceleration of the rider in the accident has verified the running state of bicycle accident. The distribution of body scars and traces of non-motorized vehicle characteristics of the distribution is summarized.
