Why should Suzhou build a light rail instead of a subway?

Legal analysis: combining with local development needs. The difference between subway and light rail is first manifested in axle load. The axle load of subway is generally greater than 13 ton, and that of light rail is less than 13 ton. Secondly, generally speaking, the plane curve radius of the subway is not less than 300 meters, while the light rail is generally between 100 meters and 200 meters. In addition, the subway has more trains and more vehicles than the light rail. During peak hours, the one-way transportation capacity of subway lines reaches 30,000-70,000 passengers respectively, while the transportation capacity of light rail lines is 60-20,000 passengers.

Legal basis: "Regulations on the Operation and Management of Urban Rail Transit" Article 5 At the stage of soliciting opinions on the planning and construction of urban rail transit network, the competent department of urban rail transit operation should comprehensively consider the factors such as the connection with urban planning, the passenger demand of urban rail transit, and operational safety guarantee. Network layout and scale, transfer hub planning, construction sequence, resource sharing, integrated emergency command system network construction, line function positioning, line system format, system scale, and so on. The competent department of urban rail transit operation shall put forward opinions on passenger flow forecast, system design transportation capacity, traffic organization, operation management, operation service and operation safety at the stage of soliciting opinions on the feasibility study report and preliminary design document preparation of urban rail transit project.

"Opinions on Further Strengthening the Management of Urban Rail Transit Planning and Construction" strictly applies for construction and improves the relevant economic indicators for applying for the construction of subways and light rails. The general public budget revenue and regional GDP for applying to build a subway city have been adjusted from 654.38+0 billion yuan and 654.38+0 billion yuan to 30 billion yuan and 300 billion yuan respectively. Improve the quality of construction planning, strengthen the integration of urban rail transit and other modes of transportation, and encourage the exploration of comprehensive development and utilization of above-ground and underground space. Strict construction planning approval and audit procedures to ensure that the construction scale matches the local financial resources. Strengthen the guiding and binding role of construction planning, and the construction planning approved by the state shall not be changed in principle, further clarifying the conditions for planning adjustment and a new round of construction planning approval.
