I feel that much of what Ottawa does as “traffic calming” is badly compromised by a desire not to inconvenience the motorist at all, while purporting to make the street calmer and safer for everyone else.
Case in point: a traffic calming centre island proposed for Booth near Raymond. The design concept was approved by council years ago, but funding has finally come available. So the traffic engineers get to do the detailed design. Well, that island, you know, is just awful. To get big trucks around it they’d need to widen the road, increase the curb radii at intersections, remove landscaping, encroach on sidewalks, etc etc. Wouldn’t want that “calming” feature to actually slow down or cause motorists to think twice would we?
This traffic calming scene from Germany seemed much more based on the “tank trap” school of thought. Heavy concrete obstacles, regularly placed, force vehicles into a series of sharp turns, a bit like chicanes. It certainly could be prettier, but I suspect it does its job very well.
BTW, this is not a “telephoto” or trick shot, it must be obvious by now I am still a Kodak brownie-level photographer. Here is another bit of serious traffic calming, and very green too:
