一种基于车辆碰撞模型的经济实惠的工具，用于支持现场工作和重建
An affordable tool based on a pedestrian-vehicle collision model to support the fieldwork and reconstruction
摘要：
提出了一种基于车辆碰撞模型的自由存取工具。该模型允许定性和定量的描述事件的整体动态的一段称为碰撞前，碰撞，碰撞后。此外，它能够确定车辆与行人碰撞前的初始速度大小以及事故发生时道路上的碰撞点位置。该模型的输入与现场收集的证据有关，为支持调查员的实地工作提供了一个核对表平台。此外，碰撞前阶段使调查人员能够开展可避免性研究，这可能有助于道路安全评价。该模型进行了验证，比较结果与假人，身体和重建的情况下开发的实验案例统计。结果表明，没有显著差异，从而验证了其功能。该工具以西班牙语和英语的移动应用程序提供，使一些中低收入国家的调查人员能够负担得起。
英文摘要：
A Free access tool based on a pedestrian-vehicle collision model is presented. The model permitted the qualitative and quantitative description of the events whole dynamic by segments called pre-collision, collision, and post collision. Furthermore, it enabled the determination of the magnitude of the vehicles initial speed before the collision with a pedestrian and the location of the point position of impact on the road where the accident occurred. The models inputs are related to the evidence collected at the scene, which provides a checklist platform for supporting investigators fieldwork. Additionally, the pre-collision segment permitted the investigators to develop an avoidability study that may contribute to road safety evaluation. The model was validated, comparing the results statistically with experimental cases developed with dummies, bodies, and reconstructed cases. It is shown that there is no significant difference, thus verifying its functionality. The tool is available as a mobile app in Spanish and English, allowing significant affordability to investigators from some low and middle-income countries.
