A park with no other people in it is / sensibly percieved to be unsafe.

Yet put a regular soccer game there, add in seats so that lunchtime workers sit down for a sandwich, encourage adults to take lengthy actions that simply involve bein there and the place both becomes safer and feels safer.

It's human nature to feel safer in a well lit, public space

The space is rarely the issues - it's the lack of other people

Blame the car culture firstly, blame bad architects next, blame atrocious town planners mostly

If we want to feel safe we know how - have adults outside.
