Abstract

AbstractRoadway lighting systems play a major role in maintaining nighttime traffic safety as they reduce both the number and severity of nighttime traffic accidents. While the design of roadway lighting systems involves multiple objectives, past studies have focused on optimizing only one of the multiple objectives that should be considered. This paper presents a multiobjective optimization model for roadway lighting projects that simultaneously optimizes four design objectives. The incorporated objectives are (1) maximizing the average lighting level on the road surface; (2) maximizing the lighting uniformity along the roadway; (3) minimizing the glare to road users produced by the lighting system; and (4) minimizing the cost of operating the lighting system. The model is designed and developed as a multiobjective genetic algorithm to help decision-makers in their endeavor to provide efficient roadway lighting systems that strike a balance between the four conflicting objectives. The present model consi...
道路照明工程的多目标优化
摘要公路照明系统在维护夜间交通安全方面发挥着重要作用,因为它们既减少了夜间交通事故的数量,也降低了夜间交通事故的严重程度。虽然道路照明系统的设计涉及多个目标,但过去的研究只关注优化应考虑的多个目标中的一个。本文提出了一个道路照明工程的多目标优化模型,该模型同时优化了四个设计目标。合并的目标是(1)最大化路面的平均照明水平;(2)最大化巷道照明均匀性;(3)尽量减少照明系统对道路使用者产生的眩光;(4)最大限度地降低照明系统的运行成本。该模型被设计和开发为一个多目标遗传算法,以帮助决策者努力提供有效的道路照明系统,在四个相互冲突的目标之间取得平衡。目前的模式是……
