国外一项研究结果表明,当一个城市人口规模超过100万人时,以城市轨道交通为骨干的交通系统结构,具有明显的技术经济优势;而人口不到100万人的大中城市,为适应可持续经济发展战略的长远需要,解决城市交通问题,也需要发展城市轨道运输。目前,我国人口过百万的城市已有34个,而城市居民人均 GDP 超过2000美元的城市达到56个。这些城市中的大多数已经开始规划设计自己的“轨道之梦”。目标直指2020年对于未来城市轨道交通的发
A foreign study shows that when the population of an urban area exceeds 1 million, the transportation system with urban rail transit as its backbone has obvious technical and economic advantages. For large and medium-sized cities with a population of less than 1 million, The long-term needs of sustainable economic development strategy to solve urban transport problems also need to develop urban rail transport. At present, there are 34 cities in our country with a population of over one million, while 56 cities have a per capita GDP of over USD2000 for urban residents. Most of these cities have begun planning to design their own “orbital dream.” Targets point to 2020 for the future development of urban rail transit
