Hmmm. I’ve walked these streets regularly and I didn’t know about the new rules.
As usual, it feels like the devil is in the details.
I don’t think it’s obvious to anyone in those areas that there are new rules. Signage etc is probably part of the problem. If you’re a motorist in the CBD, you’re managing and paying attention to a lot. It’d be pretty easy to miss a small sign about a whole new set of rules, especially if no one else knows and isn’t behaving differently.
The one place where speeds have reduced is notable because there is just so much pedestrian foot traffic through there that a safety in numbers effect has to kick in for pedestrians. I suspect that has nothing to do with the new rules.
In the end though, the idea of more pedestrian friendly roads (ie car ways) is, I suspect, a paradox. A car is intrinsically “unfriendly” (ie deadly) to pedestrians who always naturally give way to car out of a sense of self preservation. This is a city that only a few years ago had a motorist go on a killing spree on the CBD just with their car (to which the govt is responding with car blocking poles everywhere).
Speed bumps could help. Very obvious and large signage stipulating that these are pedestrian areas in which cars are free to try to get through could help too.
One change that could maybe go a long way would to rip up the bitumen and replace it with a pedestrian friendly surface. Everyone would pick up on that cue: human not car area.
Part of the issue here though is that the Council don’t want to make a bold decision and are trying to tentatively explore without commitment. With such measures, the inherent power dynamic between cars and pedestrians is probably always going win out.
