构建了TOD模式下城市轨道交通与土地利用的协调关系评价指标体系,通过修正的数据包络分析(DEA)方法对城市轨道交通与沿线土地利用的协调关系进行了评价与排序.将不同输入、输出指标进行均值化处理,通过分析不同指标间的松弛变量和剩余变量,得出各个指标对城市轨道交通与土地利用协调发展的影响程度.根据DEA有效前沿面投影理论,提出DEA无效决策单元实现协调发展时应达到的标准,为无效决策单元的改进提供了参考.以美国阿勒格尼为案例进行分析,结果表明:该评价方法分析结果与实际情况一致,能够较好地评价城市轨道交通与土地利用的协调关系.
This paper establishes an evaluation index system of coordinated relationship between urban rail transit and land-use under TOD mode. The evaluation results and rank are generated by the improved DEA model. Different input/output indexes are standardized through further analysis of different indexes' slack variables and surplus variables. The influencing degrees of different index factors to the coordinated relationship are examined. The improved directions of DEA invalid decision making units (DMU) are also analyzed through the DEA projection theory, which provides an improved reference to the invalid DMU. A case of Allegheny country in U.S. is conducted to verify the evaluation method, and the results show that the evaluations mach well with the real situations. It is an effective way to evaluate the coordinated relationship between urban rail transit and land-use under TOD mode.
