Is this possible?

Is it possible at a stop some people get on then some people get on a bit later like you have to wait a bit at a stop. (This will be used for a custom map)

Is it right that these passengers are coming from another bus/train and are transits? This is an interesting thing... until know that's not possible.

Think of it as you're waiting at a train station in your bus and some people get on and then a bit later more get on instead of them all getting on at once.
