Subway is a high-density and large-capacity urban rail transit system, covering all kinds of underground and above-ground road rights in urban areas.
Introduction of subway characteristics
Saving land Because the value of urban land in general metropolises is high, building the railway underground can save the ground space and make the ground land available for other uses.
The noise-reducing railway is built underground, which can reduce the noise on the ground. Reduce interference Because the running route of the subway does not overlap or cross other transportation systems, there is less traffic interference, which can save a lot of commuting time.
Saving Energy Under the problem of global warming, subway is the best public transport. Because the subway runs smoothly, it saves a lot of commuting time, makes people happy, and also replaces a lot of energy consumed by driving.
Reduce pollution. Ordinary cars use gasoline or oil as energy, while subways use electricity. No tail gas emission, no pollution to the environment.
