Expressway, as the main framework of urban road network, needs to build a composite channel system, which has a strong external rapid traffic function and serves the urban functions of the areas along the road. By starting with the travel characteristics and needs along the ground laying section, the planning and design ideas and schemes of main and auxiliary layout are put forward in accordance with local conditions and node transformation is reasonably connected,An important channel that effectively connects the city,and rationally sorts out the regional roads internally,which provides a reference for the construction of ground expressway compound channel system in rapid urbanization areas in China.
