An urban regional traffic network is the base of regional traffic planning. The visual method of traffic network, which uses interactive editing and optimization methods, make editing and displaying network information more efficient. The use of MapInfo's and TransCAD's visual editing functions contributes to establish the clear, intuitive layer-structure of a traffic network that has strong maneuverability. In this paper, the optimization method based on visual analysis of a regional traffic network is discussed, which is based on the regional case of Changsha's Yanghuyuan. The paper realizes...
