An Evaluation on Coordinated Relationship between Urban Rail Transit and Land-use under TOD Mode

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 match 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.

摘要：针对局部交通状况分析所需要的多粒度仿真功能，本文分析了从宏观规划模型到微观仿真模型转换时的逻辑保证和数据需求，设计了一种基于路径流的多粒度交通仿真方法，从物理、逻辑和运行三个层面实现了从基于点和线的宏观路网到基于车道的微观路网的转换。针对转换过程中交通小区质心及其路网连接线等虚拟实体的处理问题，本文进一步提出了新的支路近似方法。基于上述方法，开发了适用于TransCAD和VISSIM间模型转换的软件包，方便地实现了从宏观路网中局部区域交通状况分析到微观路段交通流量仿真的一致性转换。
