基于熵值法的行人过街设施分析评价及优选

Analysis, Estimation and Optimization of Pedestrian Crossing Facilities Based on Entropy Method

步行交通是城市交通系统中的重要组成部分。该文分析了行人过街设施的三种类型,人行横道线、人行天桥及人行地道,在此基础上,分析了过街设施的现状问题。最后选取了等待时间、绕行距离、安全性、对交通流的影响等13项指标,应用熵值法对这三类过街设施进行综合评价,并应用于实例,结果表明该方法具有一定的实用性。

The walking traffic is an important part in urban traffic system. The article analyzes three types of pedestrian crossing facilities, i.e. pedestrian crossing, pedestrian overpass and pedestrian subway. On this basis, the article analyzes the present problems of crossing facilities. Selecting 13 indexes of waiting time, detour distance, safety, traffic flow and etc., the entropy method is used to comprehensively estimate these three types of crossing facilities, and is used to the practices. The result shows that this method has a certain practicability.
