I would say this is a tagging error. When you have a highway, it's a
line feature, but it's understood to have width on either side of the
line. A barrier that ends in the middle of the highway will block half
the highway. It is extremely unlikely that this exists in raelity.
Thus, the question is whether a router should guess:
- A) tagging error: barrier stops just short of highway
+ ignore barrier
- B) tagging error: barrier actually continues
+ way is not routable
- C) tagging correct: barrier literally stops at centerline of highway,
blocking one direction
+ way is passable in one direction, based on where barrier is and
drive-on-left or not
I vote for
- routers should pick A
- validators should flag this
