道岔是跨座式单轨交通系统的关键组成之一，其作用是实现跨座式单轨车辆在行驶过程中的转线、折返 运行及在车辆基地的调车。通过对折线型道岔平面线形的研究，总结出道岔平面线形的设计方法和关键参数，对 设计标准中给出的道岔线形进行验证，并对道岔的线形设计和表达式提出设计建议。

Turnout is one of the key technologies of straddle-type monorail transit systems. Its function is to realize the turning operation of straddle monorail vehicles in the process of driving and the shunting function in the vehicle base. Through the research on the plane alignment of broken line turnout, this study summarizes the design method and key parameters of the plane alignment of turnout, verifies the turnout alignment given in the design standard, and puts forward suggestions for the alignment design and expression of turnout.
