On a related note (i trust) I recall that when Perry Vale was "restructured" when the new flats were built, there were calls for crossings for pedestrians crossing the dangerous Waldram Place (with all the cars joining PV from the South Circular) and across Perry Vale itself to the station and the underpass.
Instead, we were told that "research shows" that NOT putting in traffic calming measures and pedestrian crossings was somehow supposed to result in more careful driving since the risk factor was elevated.
I never believed it, and I don't know of the accident statistics for that section of road, but I would not feel comfortable with my kids trying to cross them alone if they were heading to the station.
In any case, I seriously wonder whether that research was up to date enough to take into consideration not just drivers' attention, but pedestrians engrossed in their smartphones and plugged in earphones.
My wife witnessed a lady almost getting over just a couple of days ago for that very reason.
Yes, if cars were to drive more slowly that might help, but as others have said, not all will or do, so purposely putting pedestrians at risk seems foolhardy
