Motorcycle crashes with roadside objects often involve more than one impact event: typically involving a collision with the ground and another object. The objective of this study was to determine the fatality risk in these roadside object collisions when compared with crashes only involving a collision with the ground. The roadside objects analyzed included guardrails, concrete barriers, signs, utility poles, and trees. The Fatality Analysis Reporting System (FARS) database was used in conjunction with the General Estimates System (GES) to analyze fatality risk for motorcycle crashes from 2004 to 2008. The analysis was based upon over 3600 fatal motorcycle crashes with roadside objects. Collisions with roadside objects were found to have a higher fatality risk than collisions with either the ground or another motor vehicle. Based on the most harmful event reported in the crash, motorcycle collisions with guardrail were 7 times more likely to be fatal than collisions with the ground, and collisions with trees were almost 15 times more likely to be fatal than collisions with the ground. Additionally, the roadside object was reported as the most harmful event in the majority of the crashes in fatal two-event crashes involving a roadside object and a collision with the ground, with the exception of collisions with signage. From these analyses it was concluded that collisions with fixed objects are more harmful to motorcyclists than collisions with the ground.
通常涉及与地面和另一个物体的碰撞。本研究的目的是确定与仅涉及与地面碰撞的事故相比，这些路边物体碰撞中的致死风险。分析的路边物体包括护栏、混凝土障碍物、标志、电线杆和树木。使用伤害分析报告系统 (FARS) 数据库和一般估计系统 (GES) 分析 2004 年至 2008 年的摩托车碰撞致死风险。该分析基于超过 3600 起致命的摩托车与路边物体碰撞事故。与路边物体的碰撞比与地面或另一辆汽车的碰撞具有更高的致死风险。根据事故中报告的最严重事件，与护栏的碰撞比与地面的碰撞更有可能致命，与树木的碰撞比与地面的碰撞更有可能致命近 15 倍。此外，在涉及路边物体和与地面碰撞的致命两事件碰撞中，大多数事故报告中路边物体是最严重的事件，除了与标志的碰撞。从这些分析中可以得出结论，与固定物体的碰撞对摩托车手比与地面的碰撞更具危害性。
