I'd like bus shelters to bear accurate mathematically distorted
geographical maps, where, for instance, distance from the centre of
the map is proportional to the square root of the actual distance on
the ground, and any super-long routes have an arrow at the edge of
the map listing further destinations.

How do you handle the case where two bus routes share the same stretch
of road, diverge, and then rejoin at another point?

You either give them different colours, or you show them as separating and
converging like the Northern Line - whichever makes the map easier to
understand (which would depend on what else was going on in the map).

But then this would destroy the accurate mathematical distortion
property.
