He replied that the council had decided that the crossing would only activate when there was no traffic coming
got one of these on my commute, on a bend where people regularly seem to speed, sooooo annoying. The gap the crossing waits for is invariably bigger than a gap I'll wait for. This is the only flowing part of the road, normally jams either end so can't see having a prompt response from the crossing disrupting travel time much if at all. Been meaning to speak to council about it.
This is a not very well used BW crossing so repeated use or "pedestrians massing" are highly unlikely to happen.
TBH many crossings seem a bit crap really nowadays, one in bury oustide The Rock I remember, to get across a road you have to use 3 crossings, the ped section is part of the main sequence and aren't co-ordinated so crossing takes several minutes - or you can just vault the barriers and walk across in a few seconds.
