Abstract:The layoutand scale of urban expressway network are determined by the urban spatial pattern, road network form, traffic demand characteristics and other factors. Dalian City is located in the south end of Liaodong Peninsula, and is the obvious cluster city with many mountains and low hilly. Its traffic network pattern is different from the inland plain cities and its traffic mode is the diversified development. Under this background, its status of urban rapid transit is prominent and important. At the same time to synthesize the generalized deciding essentials, the specific urban structural features and diversified traffic characteristics of Dalian are integrated. The targeted planning principle of "making pattern by shape, making scale by resource" is proposed. Through the functional orientation and combination of "radiation line, interval line, structure line and transition line", the expressway network of "clear functions, balance of supply and demand, and multiple interactions" is built in order to maximize the utilization benefit of comprehensive traffic resource, enrich and perfect the planning theory and method f urban expressway, and also provide the reference for the planning of the similar urban road networks.
