摘要
基于分形理论从城市轨道交通车站加权中位点与城市交通需求加权中心吻合度、城市轨道交通网络与城市道路网络的分形一致性和方向协调性三个方面分别构建城市轨道交通与城市的协调性指标,然后构建综合协调性指标。以宜宾市智能轨道交通规划线网为例,分析了两个规划方案与宜宾市的协调性。结果表明方案一与宜宾市的综合协调性优于方案二,该方法及评价指标能较为全面的评价城市轨道交通与城市之间的协调性,能为选择最优方案提供一定依据,对加强城市轨道交通与城市的协调性也具有一定的指导意义。
Based on fractal theory, the coordination indicators of Urban Rail Transit and urban are constructed from the consistency of the weighted median site of Urban Rail Transit stations and the weighted center of urban traffic demand, the fractal consistency and directional coordination of Urban Rail Transit network and urban road network, respectively. Then, the comprehensive coordination indicator is constructed, by taking Autonomous Rail Rapid Transit network planning of Yibin for example. The coordination between two schemes and Yibin are analyzed, respectively. The result shows that the scheme one is more coordinate with Yibin than scheme two, and that the coordination between urban rail transit and urban can be evaluated comprehensively through the method and evaluation indicators used. This study can provide a certain basis for selecting the optimal scheme. It is also of guiding significance to strengthen the coordination between Urban Rail Transit and urban.
