# 如何找到多式联运路线
CalculateRoutes API 支持`Intermodal`出行模式来计算在单次旅程中结合多种交通工具的路线，例如开车到停车和乘车地点，然后乘坐公共交通工具前往目的地。行人支腿始终处于启用状态，以便在其他交通工具类型之间进行连接。
## 潜在使用案例
+ **停车和乘车：**开车前往公交车站、停车，然后乘坐公共交通工具，以避免市中心的拥堵和停车费用。使用 `Vehicle` “启用” `FirstLeg` `Taxi` 和 “`Rental`禁用”。
+ **出租车和乘车：**从起点乘坐出租车前往交通便利的公交车站，然后在剩下的旅程中改用公共交通。这对于公共交通不便的区域或想要完全避开停车的地方非常有用。使用 `Taxi` “启用” `FirstLeg` `Vehicle` 和 “`Rental`禁用”。
+ **Last-mile 交通：**在旅程的大部分时间里乘坐公共交通工具，最后一站使用出租车或租车到达最终目的地。
