I think almost everywhere there are regular stops and request stops. How much each type is utilized, and how well they are differentiated, is what differs regionally.

Buses in Europe tend to be pretty good for this, there is an announcement that the next stop is a request stop and you have to press the stop button to disembark. (It is also explained on the information screen). Gets a bit annoying if you use the bus regularly, but makes it much better for new users.
