To help reduce the number of pedestrians lying on the road suffering fatal or severe injuries as a result of vehicle collisions, we investigated the influencing factors. We conducted an analysis of the records of the Institute for Traffic Accident Research and Data Analysis Japan between 2012 and 2018; we found that 2452 pedestrians lying on the road were involved in collisions (797 fatalities, 784 severely injured, 871 mildly injured). Multivariate logistic regression analysis identified the following as major factors that positively influenced the fatalities: head or neck injuries (odds ratio [OR], 90.221); trunk injuries (OR, 71.040); trucks as offending vehicle (OR, 2.741); collision velocity of 10-20 km/h (OR, 31.794), 20-30 km/h (OR, 2.982), 30-40 km/h (OR, 8.394), 40-50 km/h (OR, 16.831), and >50 km/h (OR, 18.639); and hit-and-run cases (OR, 1.967). The following had a positive influence on severe injuries: trunk injuries (OR, 4.060); collision velocity of 10-20 km/h (OR, 2.540), 20-30 km/h (OR, 3.700), 30-40 km/h (OR, 5.297), 40-50 km/h (OR, 5.719), and ≥50 km/h (OR, 5.244); and hit-and-run cases (OR, 2.628). Decreasing the collision velocity, avoiding collisions to the head and neck or trunk, and preventing hit-and-run cases would be effective in reducing fatal or severe injuries to pedestrians lying on the road.
为了帮助减少因车辆碰撞而躺在路上遭受致命或重伤的行人数量，我们对影响因素进行了调查。我们分析了日本交通事故研究与数据分析机构2012年至2018年的记录；我们发现，有2452名躺在路上的行人卷入了碰撞事故（797人死亡，784人重伤，871人轻伤）。多因素逻辑回归分析确定了以下为对死亡有正向影响的主要因素：头部或颈部受伤（优势比[OR]，90.221）；躯干受伤（OR，71.040）；肇事车辆为卡车（OR，2.741）；碰撞速度为10 - 20公里/小时（OR，31.794）、20 - 30公里/小时（OR，2.982）、30 - 40公里/小时（OR，8.394）、40 - 50公里/小时（OR，16.831）以及大于50公里/小时（OR，18.639）；以及肇事逃逸案件（OR，1.967）。以下因素对重伤有正向影响：躯干受伤（OR，4.060）；碰撞速度为10 - 20公里/小时（OR，2.540）、20 - 30公里/小时（OR，3.700）、30 - 40公里/小时（OR，5.297）、40 - 50公里/小时（OR，5.719）以及≥50公里/小时（OR，5.244）；以及肇事逃逸案件（OR，2.628）。降低碰撞速度、避免碰撞头部和颈部或躯干以及防止肇事逃逸案件，对于减少躺在路上的行人的致命或重伤将是有效的。
