修建地下铁道的明显优越性在于,不占有地面空间,而是充分开发利用地下空间,它与地面公交运输等其他车辆互不争道,互不干扰,为此可以畅行无阻;地铁也不受恶劣气候的影响,能做到全天候运营。加上地铁客运量大、行驶速度又快,是解决城市地面交通拥挤的最佳措施。随着经济建设的发展与对外开放的需要,对大城市交通的需求就日益增长。尤其对于客流密集的交通走廊来说,就必需考虑用大容量有轨交通解决。
The obvious superiority of the construction of the Mass Transit Railway is that it does not occupy the ground space. Instead, it fully exploits and exploits the underground space. It does not compete with other vehicles on the ground such as bus transport. It can work without obstacles and the subway can withstand unhealthy weather. Impact, can be done around the clock. Coupled with the large passenger volume of the subway, fast driving speed, is the best solution to the urban traffic congestion on the ground. With the development of economic construction and the need of opening to the outside world, the demand for traffic in big cities is increasing day by day. Especially for the dense traffic corridor, we must consider the use of large-capacity rail transport solutions.
