Abstract

Current screening methods that assess the potential for roadway lighting to decrease nighttime crashes have not been updated since the 1970's. The existing methods dilute the influence of important factors and are inadequate for roadways where crash histories are unavailable. In this effort a two-part method for the screening of needs for roadway lighting is developed. First, an exposure assessment describes individual and population exposures to crashes, comparing projects by night-to-day crash rate ratios and traffic volumes. Outcomes of exposure assessment are based on potential crash reductions and costs of available lighting technologies. Second, a site specific analysis applies a set of eight engineering factors that suggest lighting would have benefit. Night crash histories on over eighty unlighted sections in three regions of Virginia are collected and studied in testing of the method. The effort has importance across transportation systems for screening of needs for visibility improvements.

通过暴露评估和场地参数筛选道路照明的需求

目前评估道路照明减少夜间交通事故潜力的筛选方法自20世纪70年代以来就没有更新过。现有的方法淡化了重要因素的影响，对于无法获得碰撞历史的道路来说是不够的。在这项工作中，开发了一种分两部分筛选道路照明需求的方法。首先，风险评估描述了个人和人群对碰撞的风险，通过夜间碰撞率比率和交通量来比较项目。暴露评估的结果是基于潜在的碰撞减少和可用照明技术的成本。其次，对具体地点进行分析，采用一组八个工程因素，表明照明将有好处。在弗吉尼亚州三个地区的80多个没有照明的路段收集和研究了夜间撞车历史，并对该方法进行了测试。这项工作对于筛选能见度改善的需求在整个运输系统中具有重要意义。
