Since the second half of the 20th century, with the development of urbanization in the world, the urban areas of various countries in the world are gradually expanding, and the urban population is gradually increasing, which makes all countries in the world face severe challenges in traffic problems. The trend of urbanization puts forward new requirements for the capacity and service level of urban public transport, and the development of urban traffic affects the function and development of the city. In order to make the urban functional activities can be carried out normally and efficiently, in order to protect the urban ecological environment and realize the sustainable development of urban social economy, countries all over the world take the solution of urban public transport as an
Rail transit appeared in cities as public transportation for a long time in the world. With the development of science and technology and urbanization, mass transit plays an increasingly important role in modern big cities. The history of urban transportation development in economically developed countries tells us that only by adopting rail transit system with large passenger traffic volume is an effective way to fundamentally improve the situation of urban public transport. As the application technology and basic theory of urban rail transit in China are still in the development stage, most of the project implementation is to introduce technology and equipment, and the low localization rate has become the main reason for the high project cost. Therefore, to improve the technical strength of China’s urban rail transit industry, give full play to the ability of independent construction, and strive to reduce the project cost should always be the key to the development of mass transit.
