Rail transit has attracted people’s interests due to its characteristics of large capacity, punctuality, convenience, and low carbon, thus ing an indispensable transportation mode in future. At present, urban rail transit is developed vigorously in major cities in China as well as around the world, which induces people’s thought on kinds of problems brought by rail transit. Urban rapid transit is a systematic engineering with broad effect, deep comprehension, and huge invest, and is emphasized by the government and scale and layout planning of urban transit not only are related with investment scale of engineering construction, but also determine operation effect and function of transit in urban transportation system to a large extent, therefore they attract engineering and munities’ attention. This thesis is based on the realit
