In the United States, passenger vehicles are shifting from a fleet populated primarily by cars to a fleet dominated by light trucks and vans (LTVs). Because light trucks are heavier, stiffer, and geometrically more blunt than passenger cars, they pose a dramatically different type of threat to pedestrians. This paper investigates the effect of striking vehicle type on pedestrian fatalities and injuries. The analysis incorporates three major sources of data, the Fatality Analysis Reporting System (FARS), the General Estimates System (GES), and the Pedestrian Crash Data Study (PCDS). The paper presents and compares pedestrian impact risk factors for sport utility vehicles, pickup trucks, vans, and cars as developed from analyses of US accident statistics. Pedestrians are found to have a two to three times greater likelihood of dying when struck by an LTV than when struck by a car. Examination of pedestrian injury distributions reveals that, given an impact speed, the probability of serious head and thoracic injury is substantially greater when the striking vehicle is an LTV rather than a car.
在美国,乘用车正从主要由轿车构成的车队,转变为以轻型卡车和厢式货车(LTV)为主导的车队。由于轻型卡车比乘用车更重、更硬,且在几何形状上更钝,它们对行人构成了截然不同类型的威胁。本文研究了碰撞车辆类型对行人死亡和受伤情况的影响。该分析纳入了三个主要数据源,即死亡分析报告系统(FARS)、一般估计系统(GES)和行人碰撞数据研究(PCDS)。本文呈现并比较了根据美国事故统计分析得出的运动型多用途汽车、皮卡、厢式货车和轿车的行人碰撞风险因素。研究发现,行人被轻型卡车撞击时死亡的可能性是被轿车撞击时的两到三倍。对行人受伤分布的检查表明,在给定撞击速度的情况下,当撞击车辆是轻型卡车而非轿车时,严重头部和胸部受伤的概率要大得多。
