摘要
随着我国经济建设的飞速发展以及城市规模的迅速扩张,城市化进程正在逐步加快,大量人口涌入城市,人们出行和物资交流频繁,交通供需矛盾日益凸显,城市交通拥挤成为世界各国所面临的难题。地铁在目前城市道路交通严重拥挤的情况下,有效减少了路面机动车流量。地铁在解决城市交通拥堵、改善城市布局方面发挥着积极作用。但地铁工程高额的初始投资始终是困扰地铁事业发展的主要问题之一。因此研究如何对其进行控制有着十分重要的意义。
With the rapid development of economical construction and the fast expansion of urban scale,the urbanization process is gradually quickening,a great deal of population come into city,the people travel and the materials exchange frequently,the traffic contradiction between supply and demand is prominent day by day,and the urban traffic congestion becomes the difficulty faced by every country in the world.Under the condition of serious traffic congestion of urban roads now,the metro can efficiently decrease the ground motored vehicle flow.The metro plays the positive role in the solving of urban traffic congestion and the improvement of city layout However,the high primary investment of metro engineering is always one of the main problems persecuting the metro industry development.Therefore,it is very important how to control the investment.
