Cycling in Waterloo Region

What's a vertical diversion? The Dutch cycling article didn't mention that.

I think it means bumps, humps, or any other vertical diversion of the road surface. I think long speed humps are underused — they make the street uncomfortable for fast traffic without making much difference to traffic moving at an appropriate speed. By contrast, old fashioned speed bumps require slowing to almost zero to go over, which does not improve safety compared to a more reasonable speed. The main counter-argument seems to be from emergency services, but I consider that to be mostly invalid because most of the trip taken by emergency services will be on main streets that obviously will not have humps (being designed for some measure of speed). If the residential street which is the location of the call has humps, that just delays the last 1 minute or so of the ambulance trip by a few seconds. In the meantime, on all the days when an ambulance isn’t called for, the slower traffic is saving lives.
