城市轨道交通的建设耗资大、工期长、难度高,在其规划时应着重考虑:用尽量少的总里程覆盖尽量多的面积;最先修建的线路是最急需的;符合可持续发展原则。提出了一种适用于大城市的轨道交通网络规划方法,能同时较好地达到这3个目的。
The construction of urban rail transit is costly, long construction period and high difficulty. Consideration should be given in its planning: it should cover as few areas as possible with a minimum total mileage. The first line to be built is the most urgently needed. It is in line with the principle of sustainable development. A planning method of rail transit network suitable for large cities is proposed, which can achieve these three purposes at the same time.
