Introduction

Hit-and-run crashes occur when the driver at fault leaves the scene without reporting, which could delay emergency response for the victims who are left. For this reason, it is assumed that hit-and-run crashes lead to more serious injuries; however, the research in this area is limited. The objectives of the study are to examine the differences in hit-and-run and non-hit-and-run victim injury severities and to identify the factors that may influence any differences.

Methods

Quasi-induced exposure technique, an indirect method, is employed to measure the relative crash exposures between hit-and-run and non-hit-and-run crashes using Michigan two-vehicle injury crashes 2012–2014. Random parameter ordered logit model is used to reveal the discrepancy of the factors contributing to victim injury severity.

Results

We found that the injuries sustained by the drivers left at the scene (victims) of hit-and-run crashes were generally less severe compared to non-hit-and-run driver victims, which may be attributed to the differential crash factors in terms of driver age and vehicle type. The injury-severity contributing factors of hit-and-run crashes differed considerably from the non-hit-and-run crashes. Characteristics such as occurring in rural areas, at nighttime, at intersections, crash type, and alcohol involvement significantly increased the injury severities of the driver victims.

Conclusion

We inform the hit-and-run literature to suggest a contradiction to the assumption that leaving the crash scene may lead to more serious injuries. This example emphasizes the importance of distinguishing different types of crashes and their contributing factors. We offer an indirect approach that can help to identify underlying factors and reduce bias, which can inform traffic safety methods and serve to propose effective safety countermeasures.

检查运行中和非运行中崩溃的潜在风险

介绍

当发生故障的驾驶员没有报告就离开现场时，就会发生撞车撞车事故，这可能会延迟对被害者的紧急响应。因此，我们认为，撞车撞车事故会导致更严重的伤害。但是，这方面的研究是有限的。这项研究的目的是检查即撞即逃和非撞撞受害者受伤严重程度的差异，并找出可能影响任何差异的因素。

方法

准诱导接触技术（一种间接方法）被用于使用密歇根州2012-2014年两车两伤事故来衡量撞撞和非撞撞之间的相对撞车暴露。随机参数排序的logit模型用于揭示造成受害者伤害严重程度的因素之间的差异。

结果

我们发现，撞车撞车事故现场驾驶员（受害者）所遭受的伤害通常较非撞车撞车事故受害者严重，这可能是由于撞车因素不同造成的。驾驶员年龄和车辆类型。撞车撞车事故对伤害严重性的影响因素与非撞车撞车事故有很大差异。诸如发生在农村地区，夜间，交叉路口，碰撞类型和酒精摄入等特征显着增加了驾驶员受害者的伤害严重程度。

结论

我们告知即兴运行的文献，认为与坠毁现场可能导致更严重伤害的假设相矛盾。此示例强调区分不同类型的崩溃及其影响因素的重要性。我们提供了一种间接方法，可帮助您识别潜在的因素并减少偏差，从而为交通安全方法提供依据并提出有效的安全对策。
