Evaluation Method Of The Development In Metro Station Area Based On TOD In Beijing

With the rapid development of urbanization,the problems such as disorderly spread of landuse and inefficient traffic condition become worsen,which pushs Beijing to pay more attention on combining landuse and traffic development in the process of urban development.Transit Oriented Development(TOD)is an effective way to integrate land use,transit and other aspects of urban planning,which offers great possibility to optimize landuse and traffic together in urban development.To analyse the inner correlation of landuse and rail transit baesd on TOD mode,guide to optimize landuse and traffic condition,help to plan new metro station,an assessment method need to be built to judge the development result of TOD in metro station area.For that,this paper studys some aspects as follow:First,summarized some practical cases and research papers of TOD,analysed current condition in Beijing by SWOT analysis method.Making clear that the metro stations area had some strength and opportunity to develop TOD,such as policy support and great practice condition,meanwhile,facing great challenges and weaknesses,such as large system and difficult operation as well.Second,chose the evaluation objects of metro station area in Beijing in view of TOD.Chose density of residents,density of jobs,plot ratio and rail transit volume as landuse and traffic indicators.Use ArcGIS data,chose node-palce model to select preliminary evaluation objects,obtain 25 metro stations.Then analysed the correlation between travel in or out of metro station area and landuse mode,combined the model of accessibility,which used ArcGIS and CUBE to deal with data,and mixedness entropy index model to build metro station area classification method,finally got 4 evaluation objects.Third,summarized evaluation system of TOD in metro station area at domestic and aboard,ensure the five evaluation dimensions including,landuse,travel,economy,environment,and social perception.According frequency of occurrence and Delphi Method to determine the evaluation system with five dimentions and three levels,then explain the meaning and calculation method of 23 indicators.Because of the fussiness of TOD and indicators,used Fuzzy Comprehensive Evaluation Method to evaluate,in which,combine Grey Relational Analysis and Coefficient of Variation to determine weight of each indicator,improved the accuracy of the method to determine weight objectively.Finally,based the result of classification,chose 4 metro station areas,including,Wangfujing,Chaoyangmen,Jintaixizhao and Guomao,to use the evaluation method.The result showed that,4 areas were all in middle development level,which indicated that TOD development condition in Beijing's metro station areas should be strengthen.Then,analysed the whole results and each dimension of subjects in study,analysed the casue leading to the development results in 3 aspects,including traffic,land-value,and perception.At last,some advices were put forward according to the result,which can offerred proper guide to improve development condition in metro station area based on TOD.
