General Urban Kitchener Updates and Rumours

On turn Radii you're absolutely right, if there's a low roll curb, the radii should be effectively zero...

I’m not sure what you’re agreeing with here. I didn’t say anything about roll curbs; my point is just that if right turns aren’t permitted, the curb can come to a sharp corner instead of being rounded off to provide a turn radius. A roll curb that comes to a sharp corner is dangerous because it makes it look to pedestrians like they have a safe space right at the corner but provides not even a hint to a vehicle that it has transgressed into pedestrian space.

The point is, if there is a roll curb which is intended for drivers to cross, there is no reason to provide a turn radius, a sharp corner will slow vehicles down, and the few large vehicles, which need the turn radius can safely navigate up the curb to make the turn. Pedestrians can stand there, just as cars can move up to the line, but both may need to move to accomodate the occasional large vehicle squeezing through.
