Research On The Evaluation Index System And Method Of Transit Oriented Development

Transit oriented development is a new type of transportation and land use pattern,it can effectively reduce traffic congestion and energy consumption.However, in the real TOD project, there is a lack of systematic evaluation toward the effect and the level of its development. In order to determine the impact of TOD mode on urban transportation、 environment and economy, conducting the sustainable development of the city, there is a need to establish a scientific and feasible evaluation index system to provide theoretical support for TOD mode. In this paper the following aspects are mainly studied:Some systematic analysis and summary are made on the development status of TOD:through the horizontal comparison of foreign and domestic development status of TOD, a summary is made of its development experience and lessons learned. In this paper, the characters of high-density development、high-intensity use and high-accessibility design are used as a breakthrough and focus in the research of the index system, and a review is made for the domestic development status of TOD to reveal the problems existed in this evaluation index system.A detailed analysis is made of the definition the principle、the development model and the basic structure of TOD, as well as the effectiveness and impacts of the development of TOD. On the basis of full reference to the evaluation index systembuilding principle、method and process, and considering the characteristics of TOD evaluation data and problems of the three-H characters mentioned and the index system, the paper uses delphi method, great correlation methodand selecting typical index method to chose relative indicators, establishing the TOD comprehensive evaluation index system model covering four aspects of transportation, land use, socio-economy and environmental quality, and then making systematic analysis and argument on it. In addition, detailed descriptions and computational model introductions are made to some key indicators.Given the fact that the index is difficult to quantify and the data is difficult to obtain on the research of TOD, combined with the definition and characteristic of the TOD developmentand after much consultation, demonstration, and scrutiny, an2km2area at south Xizhimen is finally chosen for studying, questionnaires are issued to obtain detailed basic information and statistical analysis is conducted on it, then a scientific and objective evaluation is made on the TOD development status of this area using hierarchy-fuzzy comprehensive evaluation methodand a program builded with MATLAB to reveal the problems between the development of transportation and land use in this area and give someconstructive suggestions to solve them.
