One of my bus “favourites” is this. “Edmonton, Cambridge” is the destination displayed by short working buses and has been used for generations. The list of choices offered by Journey Planner does not include “Palmers Green, Cambridge Roundabout” which is what Journey Planner chooses to call it.
“Edmonton, Cambridge Roundabout” does bring up “Palmers Green, Cambridge Roundabout” but goodness knows why the first search brings up only far less related choices.
I could list any number of illogicalities. Any journey from “Wood Green (London), Lordship Lane” starts you off at the Forest Hill version of Lordship Lane. I’ve even been told when planning a journey from the first stop in Lordship Lane to “walk to Lordship Lane”, by which it means the stop of that name in Wood Green High Road.
I think I just have to accept that it is more difficult to get place/stop naming right for buses than for the tube and that any one bus stop has far fewer users than a tube station, so any hope of sorting everything is probably a forlorn hope. I’m not convinced that the logic was thought through properly in the first place though.
