Abstract:With the substantive construction of Suzhou Rail Transit Line 11, Kunshan has become, in fact, the first county-level city in China to carry out rail transit construction. The synthetic planning of rail transit line in Kunshan meets the requirements of precision, meticulousness, depth and standardization to provide high-quality services for the realization of urban intensive development centered on rail transit. On this basis, the synthetic planning of rail transit pipelines in Kunshan focuses on the pipeline synthetic planning technologies such as multi-plan integration, vertical design optimization of nodes, space utilization optimization, and future space reservation. Emphasis should be placed on the precision of spatial scale and the clarification of processes, and it is recommended that the utility tunnels be implemented simultaneously with the track in order to provide a reference for the compilation of similar plans.
