After "three more people get on board," or get on the bus, "the driver starts on the route." “三个人上车”之后，“司机发动汽车上路了”。

The route, "route," sometimes called the route (pronounced "root"), both pronunciations are possible, is the path or the direction that the bus goes. 路线（route），有时发音是/ru:t/(与root同音)，两种发音都可以，是指公共汽车经过的轨迹或者方向。

It goes down Main Street, then goes on First Street, then goes down Central Avenue, then takes a left on Seventh Street, and comes back on Waterview Drive. 它沿着主街走，然后走到第一大街，然后走到中央大道，然后在第七街向左拐，然后回到水景大道。

That would be a route, the streets where the bus goes. 那是一条路线，也就是公共汽车走的街道。

In general, a route is a list of the streets or freeways or roads that you take to get somewhere. 一般来说，路线就是你要去某个地方要走的街道、高速公路或公路。
