Cycling in Waterloo Region

Personally, I think roll curbs are acceptable where there is no on-street parking. I personally might actually prefer them to a full curb lane in that case, as I'm not convinced the full curb provides any better protection than a roll curb and think it's main benefit is that it acts as a deterrent to people using the lane for parking.

I'd happily reconsider my opinion if studies have been done on the difference between them and how they function in different contexts, but the science is pretty scant and what research is out there is limited by the huge number of confounding variables.
