摘　　要：结合微观交通仿真、微观尾气排放模型和行人过街数学模型,计算了人行天桥对所在路段机动车的行程时间、油耗和各类尾气污染物排放量,以及行人过街时间的影响.同时,建立了一个基于IPA尾气污染物经济成本的综合经济效益评估模型,将以上三方面的影响转化为货币形式,从而综合评估人行天桥的价值.对广州市海珠区一处人行天桥进行案例研究.研究表明,该评估方法能全面、有效地评估该人行天桥的价值.In order to develop a more effective comprehensive evaluation method of transport infrastructure,the pedestrian bridge is chosen for study,and a comprehensive benefit evaluation method of pedestrian bridge is proposed.This method is based on air pollutant cost factors of IPA.By combining microscopic traffic simulation,microscopic emission model and pedestrians crossing time model,the vehicle travel time,fuel consumption,vehicle emission and pedestrians crossing time are calculated.Meanwhile,a comprehensive benefit evaluation model based on air pollutant cost factors of IPA is established to evaluate the value of pedestrian bridge comprehensively.At last,apedestrian bridge in Haizhu District,Guangzhou is chosen for case study.The result shows this evaluation method can evaluate the value of the pedestrian bridge comprehensively and effectively.
