Transportation infrastructure in urban fringe areas is relatively underdeveloped, and the construction of rail transit will further impact the existing transportation system. It is necessary to optimize the planning and layout of land along the rail transit line around the rail transit station, and create an efficient and dynamic TOD community that integrates rail transit with urban functions and transportation systems, so as to realize rail transit leading urban development. Taking the Pingshan section of Shenzhen Metro Line 16 as an example, based on the TOD planning and design theory, the TOD planning method along the rail transit line is systematically studied from three dimensions: rail station, station area and station group. After the implementation of the plan, a rail development axis of “four complementary areas and two-center linkage” will be formed along Metro Line 16, with differentiated mixed sharing of land use at each rail station, fine ecology of block building, and efficient rail connection and integration, so as to realize the TOD planning and guidance along the subway line and enhance the agglomeration and carrying capacity of the areas along the rail transit.
