Pedestrian mezzanine piazza needs marking.
Ditto steps down to Brgs Bvd from piazza.
Curved "parking aisle' is actually an access road and also in a tunnel
Steps do not join indoor corridor in that fashion: correct with pedestrian piazza

whole area needs a resurvey. Especially:
main carpark accessed from service road running in front of BTP building, not from roundabout near cashpoints as currently shown.
Taxi rank/waiting area not marked.
Add cycle route (permissive?) from here through carpark to further exit on Bourges Blvd?

Sidewalk needs resurvey as this section used to have cobblestones to prevent pedestrian use. Still there?

Two crossings here or just the one?
Max stay in short stay car park?
Could the drop off area (currently =driveway; no name) be better tagged?
