公共交通枢纽内出行信息发布效用评价方法研究

Research on Evaluation Method of Transit Travel Information Utility in Public Transit Hub

在枢纽运行过程中,如何通过合理、有效的信息诱导手段提升旅客的集散效率和枢纽的安全性已成为枢纽建设的重要内容。现有研究表明,提升交通枢纽的服务水平需要进一步掌握枢纽内部不同信息的发布效用。本文以SP调查数据为基础,将旅客对不同公共交通出行信息的重要性评价值与旅客对信息的关注度相联系,提出了基于主成分分析的不同类型旅客对信息关注度的分析方法。并从旅客对信息的关注度出发,对交通枢纽内部不同发布信息的效用进行了分析。该方法应用于上海市静安寺轨道交通换乘枢纽的调查数据,对比了不同年龄层次的旅客对各类信息的关注度,并分析了该枢纽内部不同信息的发布效用。

It＇s a vital process to promote the efficiency of flow distribution and improve the security of the transit hub through rational and effective information guidance.As is indicated by the existing research findings,it is necessary to further understand the utility of different sources of public transit travel information in the transportation hub in order to improve the service level of the hub.Based on the data of the SP survey,this paper connects the passengers＇ importance value of public transit travel information and the attention degree to the public transit travel information,and develops an approach to analyze attention degree to the public transit travel information based on the principal component analysis.Then,the utility of different kinds of public transit travel information can be evaluated.The paper takes the data set from urban railway transit hub of Jing＇an Temple in Shanghai as an example.The different attention degrees to the public transit travel information by the classified-passengers are contrasted,and the utility of different sources of public transit travel information published in this transportation hub are analyzed.
