随着我国城市人口的增多,城市交通拥挤越来越成为一个亟待解决的问题,城市轨道交通是解决这一问题的根本途径。对不同类型轨道交通系统的运量、运速、造价、占地面积、限制坡度等指标进行比较,得出不同规模与特点的城市应选择不同的轨道交通系统,以供各城市参考。 With the increase of urban population in our country, urban traffic congestion has become an urgent problem to be solved urgently. Urban rail transit is the fundamental way to solve this problem. Comparing the indexes such as traffic volume, transportation speed, construction cost, land occupation, and limited slope of different types of rail transit systems, it is concluded that different scales and characteristics of cities should choose different rail transit systems for reference of all cities.
