City Highway Layout Method in Integrated Transportation System

Based on the new requirements of integrated transportation system on the layout of city high.way network, this paper chooses the layout nodes, gets the optimal tree solving of line importance degree density, improves the highway network layout based on accessibility. As a result, new method on the lay.out of city highway network in the integrated transportation system is proposed. At last, this paper gives an example of Taicang fast-track layout planning to validate the method.
