Start with your standard double-decker bus. Now add several sets of wide doors to the curb side of the top level. Then, at busy stops, add a platform with stairs and a money accepting turnstyle.
The result will be a bus that un/loads very quickly at the top, while still allowing for normal slower
stops and wheelchair access at the bottom.

By my (unreliable) calculations, a lean-angle of 1 degree will mean that the top of the bus is around a foot closer to the top of the stop than when the bus is upright. |

Closer to 4 inches per degree. Regardless, this could be dealt with the sort of auto extending step (with pressure feedback) that is presently used in some trains to mate with uneven platforms. Said step could mount on the bus or on the platform. + |

Maybe you could just provide a dump-truck mechanism, and simply tip the whole load out the back? |

[MechE], of course (I blame an erratic degrees to radians conversion), but double-decker buses lean a lot more than one degree (I speak as a former driver of them). I like the notion though. |

Add an inflatable aircraft escape slide from the back of the top deck ..... |

We can add "Mind the gap" announcements to buses as well. |
