"3) How to plan space around obstructions like ATMs or tables"
I can't remember which consultation it was at, but I once asked why things like pedestrian crossing button-posts were placed in such stupid obstructive positions, particularly near crossings already constrained with PGR (set back at least fifty centimetres from the kerb edge to protect it from cars important motor cars from having their paint damaged) and there seems to be no consideration of how multiple poles/bus stops/shop openings/trees/bins/pedestrians with no sense of when they're standing in such a way as to block the narrow gap remaining for people using the footway for ambulation will interact once they're all installed. Can't remember what the answer was now, if I got one. At one of the Leith Walk things I tried to explain that the pedestrian throughput per unit time of a non-staggered junction would be greater than that of a two-part staggered one as there would be less impediment from having to turn through two right-angles in a confined space with people coming the other way and that it was therefore worth making all crossings unstaggered and having a universal pedestrian green on every junction, but I might have spoiled it by saying that cars would easily make up the couple of extra seconds they would be 'delayed' by simply accelerating slightly more aggressively and braking slightly more sharply on the next few segments of their journey, whereas pedestrians delayed by three or four minutes waiting for a crossing won't be able to make the time up, except by risking their lives.
