Data associated with over 9000 accidents involving large trucks and combination vehicles during a two-year period on freeways in the greater Los Angeles area are analyzed relative to collision factors, accident severity, and incident duration and lane closures. Relationships between type of collision and accident characteristics are explored using log-linear models. The results point to significant differences in several immediate consequences of truck-related freeway accidents according to collision type. These differences are associated both with the severity of the accident, in terms of injuries and fatalities, as well as with the impact of the accident on system performance, in terms of incident duration and lane closures. Hit-object and broadside collisions were the most severe types in terms of fatalities and injuries, respectively, and single-vehicle accidents are relatively more severe than two-vehicle accidents. The durations of accident incidents were found to be log-normally distributed for homogeneous groups of truck accidents, categorized according to type of collision and, in some instances, severity. The longest durations are typically associated with overturns.
分析了大洛杉矶地区高速公路上两年期间涉及大型卡车和组合车辆的9000多起事故的数据,涉及碰撞因素、事故严重程度、事件持续时间和车道封闭情况。使用对数线性模型探索碰撞类型与事故特征之间的关系。结果表明,根据碰撞类型,与卡车相关的高速公路事故的几个直接后果存在显著差异。这些差异既与事故的严重程度(就伤亡而言)有关,也与事故对系统性能的影响(就事件持续时间和车道封闭而言)有关。碰撞物体和侧面碰撞分别是就死亡和受伤而言最严重的类型,单车事故相对比双车事故更严重。对于按碰撞类型以及在某些情况下按严重程度分类的同类卡车事故组,发现事故事件的持续时间呈对数正态分布。持续时间最长的通常与翻车事故相关。
