机场接驳轨道交通专线与快速公交专用道技术经济比较

Economic Evaluation of Special Railway and Bus Rapid Transit for Airport Ground Transportation

介绍了用于接驳机场与市区的轨道交通专线与快速公交专用道的特征。目前,国内外轨道交通机场专线的客流量都较低。通过分析机场与市区间公共交通量大小、轨道交通机场专线与机场快速公交专用道的客运能力,指出当机场非中转吞吐量小于5 528万人次/年时,快速公交专用道可满足机场接驳公共交通需求。结合北京轨道交通机场线案例,从社会总成本方面对两种机场接驳专线交通方式进行了技术经济比较。分析结果表明:在机场快速公交专用道客运能力范围以内,快速公交专用道优于轨道交通专线。

In this paper,the features of two airport-downtown commuting connectors,namely a special airport railway and a bus rapid transit （BRT） are described.Based on studies of airport transit passenger patterns in the world,the possible insufficiency of air commuters to sustain a special airport railway system is pointed out.Via an analysis of the commuting volume on airport-downtown connectors,and the capacity of special airport railway and BRT,it is concluded that an airport with a through put less than 55.28 million,only a BRT line will be sufficient to handle the ground transportation demand.An evaluation criteria based on social total cost is also established,combined with a case study of Beijing Subway Airport Express,the cost of BRT is calculated,which is lower than those of any railway systems.
