世界上的大城市在面对未来的交通危机及衍生的各种问题,诸如能源消耗、环境污染、城市土地资源的利用及社会经济的时间效益等,基本上以发展城市轨道交通来作为解决城市交通问题的首选模式。天津是我国直辖市之一,是环渤海地区的经济中心。但城市交通紧张状况,特别是市中心区已在制约着天津市社会经济的发展。为实施可持续发展战略,实现“把天津市建设成现代化港口城市和我国北方重要的经济中心”的宏伟目标,解决城市交通紧张问题已成当务之急。发展快速高效、大容量、安全正点、污染小、能耗小并能节约城市用地的快速轨道交通体系,是解决天津市中心市区交通问题的理想途径。
In the face of the future traffic crisis and various problems derived from major cities in the world, such as energy consumption, environmental pollution, the utilization of urban land resources and socio-economic benefits of time and space, the development of urban rail transit basically serves as a solution to the urban The preferred mode of traffic problem. Tianjin is one of the municipalities directly under the Central Government and the economic center of the Bohai Rim. However, tight urban traffic conditions, especially in the downtown area, have constrained the socio-economic development of Tianjin. In order to implement the strategy of sustainable development and achieve the grand goal of “building Tianjin into a modern port city and an important economic center in northern China,” it is imperative to solve the problem of urban traffic congestion. It is an ideal way to solve the traffic problems in urban area of central Tianjin by developing a rapid rail transit system that is fast and efficient, large capacity, safe punctuality, small pollution, low energy consumption and economical use of urban land.
