Abstract

Traffic crashes are one of the most severe problems that affect communities worldwide. Despite that only 25% of all motor vehicle miles occur at night, about 50% of all traffic fatalities occur during night. In Jordan, traffic crashes were responsible for 4.5% of fatalities in 2007 and ranked as the third cause of death in 2010. The effect of lighting on crash reduction was evaluated in many countries around the world but none of these was in Jordan. This paper evaluates the effectiveness of roadway lighting on night-time crash reduction in Jordan before and after continuous lighting system installation. Crash data collected from the Jordanian Central Traffic Department were analysed statistically. Several variables were considered, out of them, five were statistically significant: Crash year, road surface, whether the crash occurred during the day or the night, number of vehicles involved and lighting condition. Results confirmed that lighting reduces expected crashes.

摘要

交通事故是影响全球社区的最严重问题之一。尽管只有 25% 的机动车里程发生在夜间，但大约 50% 的交通死亡事故发生在夜间。在约旦，交通事故占 2007 年死亡人数的 4.5%，并在 2010 年被列为第三大死亡原因。世界上许多国家都评估了照明对减少事故的影响，但这些国家都没有发生在约旦。本文评估了道路照明在约旦连续照明系统安装前后减少夜间碰撞事故的有效性。从约旦中央交通部门收集的碰撞数据进行了统计分析。考虑了几个变量，其中五个具有统计学意义：碰撞年份、路面、事故发生在白天还是晚上，涉及的车辆数量和照明条件。结果证实，照明减少了预期的碰撞。
