What does rail transit have to do with us?

1. Subway construction saves land first. Generally speaking, cities in China are characterized by less land and more people, high density, heavy traffic and rapid development, and the available land and space in cities are decreasing day by day. The subway has opened up a second space for human life. The multi-level utilization of land and underground resources has solved the problem of land shortage and improved the intensive use of land. Although the construction of subway needs a lot of money, it is difficult to estimate the cost saved during and after the construction and the economic benefits brought by it. For example, in construction, the cost of urban expansion, transformation and demolition can be reduced. Making full use of underground space and reducing land occupation and demolition not only reduces the construction cost of the city, but also saves valuable resources and huge investment of the country. 3. At present, the subway is a mode of transportation with less energy consumption, which also prevents the spread of energy-consuming lifestyle brought about by the development of private cars and plays a due role in alleviating energy shortage. The subway provides the public with a fast, punctual, convenient, safe and comfortable mode of public transportation, which is enjoyed and needed by the public. There is no soft sleeper, box, first class and other high and low, rich and poor, with social fairness. At the same time, subway can also improve traffic congestion, investment environment, ecological environment and urban environment, and improve people's quality of life. Subway has also played an important role in promoting social culture and urban culture. Subway plays an important role in the emergence and formation of people's ideas, ideologies, ways of thinking, lifestyles and modes of production, and in enhancing people's concepts of competition, time, order, market, efficiency, cooperation, law, etiquette, equality and human rights. It has a great impact on traditional concepts, traditional culture and traditional society.
