I was driving in Chiba and Saitama yesterday and encountered a couple new types
of barriers. I realized later one is traffic_calming=chicane.
The other one is all over rural Japan as traffic_calming=choker on rural roads
that could bypass traffic near the rivers, - but this one is not for traffic
calming, it is for enforcement of maxwidth of the bridge, similar to
barrier=hight_restrictor.
. They put very strong steel poles or guardrails along the sides and center of
the road at the maxwidth + 20 cm of a standard car. car can pass (barely, my
mirrors were 5 cm away from each pole), but a large dump truck cannot pass.
Both are in areas where commercial dump trucks or other large vehicles are
nearby, but this one is used to enforce access to the narrow bridge near a very
very busy area to keep a massive traffic jam from occurring from a stuck dump
truck.
https://goo.gl/maps/8KUw7 <https://goo.gl/maps/8KUw7> The maxwidth is signed
and guardrails are doing the job. This is width limited for the very narrow
bridge in the background.
https://goo.gl/maps/3NT9X <https://goo.gl/maps/3NT9X> The other direction.
Poles are used.
Is this a reason for creating barrier=width_restrictor ?
