Road design, safety and Vision Zero

[danbrotherston]

I believe that our red-light cameras are near zero-tolerance. But, as you say, that is not the expected "limit" when the sign says "50".

In Europe, I think it's fairly typical for the cameras to trigger on any speed more than 5 km/h over the speed limit, which seems reasonable: that allows for the lack of (visible) precision in speedometre displays and variations in human right-foot pressure.

Well red light cameras trigger if you enter the intersection after the signal turns red. There is already a grace period of the amber light which is technically still an infraction but I'd bet money has never ever had a ticket issued on it.

There is no equivalently publicly displayed speed limit equivalent. 

I wonder if speed limits would be more effective if they gave a range. And I don't mean Quebec's silly 60km/h minimum speed on the freeway. I mean on Fischer Halman Rd having a sign saying speed 50-60km/h
