Suppose there’s a bridge over water (or other section of road) where there isn’t a center divider. There’s a sign that says “No U-Turn”.
Does one map this?
Normally one waits until an intersection before making a U-turn because there’s some expectation of traffic temporarily going orthogonally to the expected travel direction. Plus it’s typically (but not necessarily) illegal to make these turns depending on locale.
I’ve seen people map these by splitting the way and using the endpoint as the via for the no U-turn though that endpoint isn’t really an intersection. Should these restrictions be removed from the data? If not, for consistency, no u-turns be added to the data if there’s a sign but no intersection?
