摘　　要：研究目的:交通网规划是区域交通建设的重要内容,合理运输通道的确定又是区域交通运输网规划的关键,现阶段相关设计、规划部门在运输通道的设计规划上大多仍停留在基于宏观分析的基础上,缺乏必要的理论支撑,急需进行相应的研究以弥补不足。研究结论:(1)区域综合运输通道可根据节点重要度计算及动态聚类分析分层,采用扇形旋转法确定;(2)通道方向基本确定后,可根据既有线路的情况和走向、区域特点、综合运输通道的功能定位、综合运输通道对外和对枢纽的衔接、相关发展政策等五个方面因素进行相应的线路走向调整;(3)该方法通过南充市区域综合交通规划实例验证可广泛应用于区域综合交通网络规划中。Research purposes： The traffic network planning is an important part of the regional transportation construction, and reasonably determining the transportation approach is the key to the regional traffic network planning. At present, the planning and design departments make the designs of the most transportation approach mostly based on the macro - analysis, lacking the necessary theoretical support. So itg urgent to do the corresponding research to make up for the deficiency. Research conclusions： （ 1 ） The regional integrated transportation approach can be determined with the rotating sector method based on the calculation of the node importance and the layering of the dynamic clustering analysis. （2） After the approach direction is determined primarily, the track direction can be adjusted relevantly according to the situation and direction of the existing track, the regional features, the functional orientation of the integrated transportation approach, the connections of the approach with outside tracks and terminal and the relevant development policy. （3） This method has been used in the Nanchong Regional Integrated Transportation Planning and the application shows this method can be used widely in the regional integrated transportation network planning.
