我国城市轨道交通评价研究进展

Research Progress of City Rail Traffic Benefit Evaluation

我国社会经济的快速发展,城市化进程不断加快,城乡一体化建设稳步推进,由此带来的城市交通与环境问题日益突出。基于轨道交通方式运量大、速度快、准时可靠、安全性强、节能环保等比较优势,重点发展轨道交通方式成为解决我国城市交通问题的趋势。目前,我国城市轨道交通建设已经进入跨越式发展阶段,已经成为世界上最大的城市轨道交通市场,建设规模之大、发展速度之快前所未有。城市轨道交通系统建设与运营成本巨大,而过于超前或滞后的城市轨道交通发展规划和建设将直接影响城市的可持续发展,这使得研究城市轨道交通系统的效益非常必要。

With rapid social and economic development in China, its urbanization process is accelerating, thus urban transportation and environmental issues is becoming increas-ingly prominent. Based on the superiority of large capacity, high speed, more punctual, more secure and more energy sav- ing and environmental protection, urban rail transportation be- come the main way to solve urban traffic problems. At pre- sent, China＇s urban rail transit construction has entered a stage of leapfrog. It has become the largest urban rail trans- port market, with the large scale of construction and the high speed of development unprecedented. For the huge cost of construction and operation of urban rail transit system, urban rail transit development planning which is too ahead or too lagging will direcdy affect the sustainable development of cities. So it makes the study on urban rail transit system＇s ef- fectiveness and its assessment methods necessary.
