Abstract: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 it's 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.
