ION - Waterloo Region's Light Rail Transit

Maybe the curb will stay low (as you say, they're nicely formed), so that emergency vehicles can enter the rapidway here - with signage that explicitly prohibits anyone else from entering?  (think No U-Turn signs on 401 at the emergency vehicle turnarounds.)  Since the curb is so high and likely not mountable by vehicles to get up onto the rapidway, maybe entering it and leaving it by road vehicle is only possible at intersections.

Here's a local example of a barrier designed to keep out regular traffic but designed to be crossable by emergency vehicles. Something like this could do the job...
