I'm not sure if you are asking about napping on the bus during a ride or while waiting for the bus. I doubt you would get up after 50 minutes - this is when the body shifts into deeper sleep stages and causes sleep inertia, which is not really conductive to being aware of your bus stop.

There may be something in the bus route that your body is able to pick up on: several stops next to each other, a bumpy ride, a twisty road, some noise or smell? It's a skill many daily commuters pick up after a while.

Do we have an "internal timer" when taking naps?
