跨座式单轨线路给中小城市发展轨道交通提供了一种新的路径选择。通过调研跨座式单轨线路的应用概 况，得出跨座式单轨目前在全球范围内尚未得到规模性应用。根据线路的功能定位和运行地理环境特征，将目前 运营的跨座式单轨分为观光旅游类、衔接类、加密类、骨干类 4 种；从投资效率、运营模式等方面研究了不同功 能定位的跨座式单轨建设运营特征，为中国发展跨座式单轨提供经验借鉴：深化跨座式单轨系统与通道客流的适 应性研究；促进跨座式单轨线路与城市综合交通网络的融合；结合功能定位与客流特征运用运输组织模式。值得 注意的是，在国内技术尚未标准化的背景下采用跨座式单轨可能存在边际成本高的问题。

Straddle monorail provides a new way for small- and medium-sized cities to develop urban rail transit. An investigation of the application of the straddle monorail lines in the world shows that straddle monorail is not being widely used worldwide. According to the functional types and geographical environment characteristics of the line, the straddle monorail in operation can be classified into four types: sightseeing, connection, densification and backbone. This study investigates the construction and operation characteristics of straddle monorail with different functional types from the aspects of investment efficiency and operation mode, providing experience for the development of straddle monorail, expanding the research on the adaptability of a straddle monorail system and its passenger flow, and promoting the integration of straddle monorail lines and comprehensive urban transportation networks. In line with the function types and passenger flow characteristics, the transportation organization mode was applied. It is worth noting that the straddle monorail will have marginal costs under the background of technology that is not highly standardized in China.
