摘要：

为了获取电动两轮车-行人碰撞事故中的特征变量和提取典型危险场景，该文通过互联网收集了 273 例带视频信息的电动两轮车-行人碰撞事故案例，对事故中的碰撞速度、碰撞角度、行人第 1 碰撞部位、行人第 1 触地部位等 13 个事故特征变量进行统计分析；使用描述性统计分析和 K-modes 聚类方法对事故中 13 个特征变量进行聚类分析。 结果显示：事故发生时，电动两轮车行驶速度一般低于 30 km/h，且碰撞位置大多集中在电动两轮车前部位置；电动两轮车-行人碰撞事故可分为 5 种典型场景，分别是垂直碰撞场景、夜间同向碰撞场景、同向侧碰场景、骑车人戴有头盔夜间碰撞场景和对向碰撞场景。该研究结果可为电动两轮车与行人碰撞事故中行人的安全对策和安全测试场景的研究提供参考。

Abstract:

In order to obtain the characteristic variables and extract typical danger scenarios in electric two-wheeler and pedestrian collision accidents, 273 cases of electric two-wheeler and pedestrian collision cases with video information were collected from the Internet. Furthermore, 13 accidents characterization variables, such as collision speed, collision angle, pedestrian's first collision point, and pedestrian's first touchdown site were analyzed via using descriptive statistical methods. K-modes method was then used to obtain the typical scenarios by conducting cluster analysis for the 13 characteristic variables. The results show that the driving speed of electric two-wheeler is generally lower than 30 km/h and the collision position mostly concentrates in the front area of electric two-wheeler. Electric two-wheeler and pedestrian collision accident scenarios can be divided into five typical scenarios: vertical collision scenario, nighttime same-direction collision scenario, same-direction side-impact scenarios, nighttime collision scenario of riders with helmets and opposite-direction collision scenario. This study can provide a reference for the study of pedestrian safety countermeasures and safety test scenarios in electric two-wheeler-pedestrian collisions.
