跨坐式单轨给中小城市发展轨道交通提供了一种新的路径选择。通过调研全球跨坐式单轨线路的应用概况,得出跨坐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,将目前运营的跨坐式单轨分为观光旅游类、衔接类、加密类、骨干类四种类型；从投资效率、运营模式等方面研究了不同功能定位的跨坐式单轨建设运营特征,为我国发展跨坐式单轨提供经验借鉴：深化跨坐式单轨系统与通道客流的适应性研究；促进跨坐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,在国内技术尚未高度标准化的背景下采用跨坐式单轨将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. Through the investigation of application of straddle monorail lines in the world, it is concluded that straddle monorail has not been widely used in the world at present. According to the functional types and geographical environment characteristics of the line, the straddle monorail in operation can be divided into four types: sightseeing, connection, densification and backbone; this paper studies 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: deepen the research on the adaptability of straddle monorail system and passage passenger flow. Promote the integration of straddle monorail line and urban comprehensive transportation network. Combined with function types and passenger flow characteristics, the transportation organization mode is applied. It is worth noting that the straddle monorail will have high marginal cost under the background of technology not highly standardized in China.
