基于OD分类的空铁联运换乘点选择研究

Transfer hubs selection of air-rail intermodel transport based on ODs classification

针对不同类型的客流起讫点(Origin-Destination,OD),确定了空铁联运的换乘点.首先,根据OD两端节点的机场和高速铁路车站的建设情况,将客流OD分为三类,并阐述经济性、快速性和方便性对空铁联运换乘点选择的影响;然后,基于既有航空和高铁客流数据建立Logit模型,说明空铁联运服务特性指标的取值方法;最后,以京广高铁运输通道中1 000 km以上的OD作为研究对象,选择了最优的空铁联运换乘点.结果表明:石家庄凭借价格优势和便捷换乘,分别在三类OD中被选择作为换乘点的次数最多.分析结果对于提高我国空铁联运竞争优势、加强综合运输发展具有指导意义.

The transfer hubs in air-rail(AH) intermodal transport are selected for different types of passenger ODs(Origin-Destination). First, passenger ODs are classified into three categories by the infrastructure construction of airports and high-speed rail stations. The influence of service characteristics, including economy, rapidity, and convenience, on the selection of AH intermodal transport transfer hub is expounded. Then a Logit model is established based on the passenger data of air transport and high-speed rail, and how to evaluate the service performance indictor of AH intermodal is illustrated. Finally, AH intermodal transport transfer hubs are selected for different types of ODs transport which are all more than 1 000 km along the Beijing-Guangzhou high-speed rail corridor. The results show that Shijiazhuang is most often selected as the transfer hub in three types of passenger ODs due to the price advantage and convenient transfer. The results provide guidance for adding competitive advantage for AH intermodal transport in China and promote the development of integrated transportation.
