换乘点是轨道交通线网构架中各条线路的交织点,是提供乘客转线换乘的车站,乘客通过换乘站及其专用(或兼用)通道设施,实现两座车站之间人流沟通,达到换乘的目的。换乘点的分布和换乘方式的灵活性,对轨道交通线网的整体功能是十分重要的,同时,换乘站的形式对轨道交通线网构架的稳定性也有着较大影响。 Interchange point is the interlacing point of each line in the rail transit network structure and is a station providing passenger transfer transfer. Passengers can communicate with each other through the transfer station and its dedicated (or combined) access facilities , To achieve the purpose of transfer. The distribution of transfer points and the flexibility of transfer modes are very important to the overall function of rail transit network. Meanwhile, the form of transfer stations also has a great impact on the stability of rail transit network.
