北京轨道交通机场线线路方案研究

A Study on the Route Scheme of Beijing Airport-line

北京机场线是我国修建的第一条市区通向机场的专用轨道交通线路,修建后可保证市中心区和机场之间交通流及时集中和疏散,缩短旅客进出机场的旅行时间。介绍了北京轨道交通机场线线路功能定位、交通制式选择、线路设计方案、技术标准、运营模式的研究情况。认为采用直线电机交通制式选线时更加灵活,可以避开环境敏感点和制约因素,对城市的环境及景观影响小,为城市轨道交通系统提供了一种新的可供选择的交通模式。

With a study on the functional orientation, the mode selection of urban transit, the design scheme of the airport-line mute, as well as its technical standards and the operation mode in Beijing, the author holds that the adoption of the storaight line could make this route selection more flexible and bring about less influnces over urban environment.
