Abstract

Objectives

Hit-and-run crashes account for about 14% of total accidents (MoRTH 2017) in India despite it being a cognizable offense under the Indian motor vehicle act of 1988. Hit-and-run crashes also account for a significant number of pedestrian crashes. A better understanding of these crashes is required to reduce the severity of pedestrian crashes. Recent reports claim that there is an increase in the number of fatal victims concerning pedestrians in 2017 over 2016. The number of pedestrians killed in road accidents has climbed from 15,746 in 2016 to 20,457 in 2017 (29.9% increase).

Methods

Nine years of pedestrian crash data from the RADMS database (2009–2017) for the state of Tamilnadu were used in this study. This study explores several factors that increase the likelihood of pedestrian hit-and-run crashes, including temporal factors, environmental factors, crash characteristics, and road features. One hundred ten variables under 30 factors were assessed for statistically significant association with hit-and-run crashes.

Results and conclusions

The results of the present study show that the perpetrator’s tendency to leave the spot of crash increases in the dark unlighted conditions. Increased likelihood of hit-and-run crashes is found during summer, winter season and in urban areas. Among pedestrian characteristics, pedestrians who are intoxicated, pedestrian locations such as footpath, crossing the road and shoulder, pedestrian victims who are injured significantly contribute to hit-and-run crashes. Factors such as day of the week, road category, collision cause, vehicle type, weather conditions, driver alcohol status, pedestrian residence type, and traffic movement were found to be statistically not significant with a 90% confidence interval. We finally discuss a few recommendations based on the results and intervention that can reduce hit-and-run pedestrian fatalities and injuries.

调查导致印度行人肇事逃逸的因素

摘要

目标

尽管根据 1988 年的印度机动车法，肇事逃逸是可识别的罪行，但肇事逃逸事故占印度总事故的 14% 左右（MoRTH 2017）。肇事逃逸事故也占行人事故的很大一部分. 需要更好地了解这些碰撞，以降低行人碰撞的严重程度。最近的报告称，与 2016 年相比，2017 年与行人有关的死亡人数有所增加。在道路事故中丧生的行人人数已从 2016 年的 15,746 人攀升至 2017 年的 20,457 人（增长 29.9%）。

方法

本研究使用了来自 RADMS 数据库（2009-2017 年）的泰米尔纳德邦九年行人碰撞数据。本研究探讨了增加行人肇事逃逸可能性的几个因素，包括时间因素、环境因素、碰撞特征和道路特征。评估了 30 个因素下的 110 个变量与肇事逃逸的统计学显着关联。

结果和结论

本研究的结果表明，在黑暗无光的条件下，肇事者离开事故现场的倾向增加。夏季、冬季和城市地区发生肇事逃逸的可能性增加。在行人特征中，醉酒行人、行人位置（如人行道、过马路和路肩）、受伤行人受害者是肇事逃逸的重要因素。一周中的某一天、道路类别、碰撞原因、车辆类型、天气状况、驾驶员酒精状况、行人居住类型和交通运动等因素在 90% 的置信区间内没有统计学意义。最后，我们根据结果和干预措施讨论了一些可以减少肇事逃逸行人死亡和伤害的建议。
