成都市综合交通枢纽邻接区交通网络优化研究

城市综合交通枢纽是现代城市中最重要的客流集散中心，其邻接区极易出现人群及车辆混杂拥堵等情况，从而影响枢纽乃至整个城市交通系统的正常运行，所以优化枢纽邻接区交通网络以保证枢纽的服务效率与水平极为重要。文章以成都四大枢纽站为例，建立空间句法导向下的枢纽邻接区城市地铁交通网络、城市道路交通网络的拓扑关系模型，通过整体集成度、平均深度、连接度等参量进行宏观及微观层面的分析，对交通网络的可达性、中心性、渗透性等进行评价，并在此基础上提出针对四大枢纽邻接区交通网络的优化建议，指导枢纽邻接区的空间发展。

Traffic Network Optimization in Adjacent Areas of Chengdu's Comprehensive Transportation Hubs

The urban integrated transportation junction is the most important visitor assembly and evacuation area in modern cities. However, adjacent areas are prone to crowd and traffic congestion, which affects the normal operation of the junction and even the whole urban traffic system. Therefore, it is necessary to optimize the traffic network of adjacent areas to ensure the efficiency of the hub service. Taking four major junction stations in Chengdu as examples, the paper establishes research models for the urban metro and urban road traffic network based on Space Syntax. Moreover, through analysis of the macro and micro levels of integration, it evaluates the mean depth and connectivity, accessibility, centrality and permeability of the traffic network state. The paper then proposes some suggestions to optimize the traffic networks in the adjacent areas of the four major junction stations, which could be used to guide the spatial developments of adjacent areas.
