This is nonetheless correct mapping! What you are seeing it the resulting impedance mismatch from using linear ways to map what on the ground are actually areas. That sort segment at a sharp angle only exists for connectivity purposes. And the data makes perfect sense when seen in the

Regarding classing paint as a barrier, you wouldn't map a bicycle lane as a cycle way if it is only a painted line ( https://www.mapillary.com/app/?pKey=285967329802439) but if there is a barrier (Kreb, Armco, parked cars, etc.) it would be mapped as a separate cycleway

Mapbox has a helpful page on the present day preference of squared intersection mapping instead of the older X mapped method. I guess this has evolved over time due to clearer and higher resolution imagery.

Thanks for the tip about the "change" tag. So here is what I've done - does it sound right? - in the section where the slip lane joins the 2-lane through road (where lanes=3), I have added: "change:lanes=not_right|not_left| " (this hopefully means that the left hand lane cannot change

There are many situations in Australia where you are permitted to cross an unbroken white line (for instance, moving to a special purpose lane). The wiki is pretty unambiguous, "where traffic flows are physically separated by a barrier (e.g., grass, concrete, steel), which prevents movements

This might be tangential to the discussion, on the other hand, it might be a kind of "hidden" or unstated assumption about how ways are "interpreted" in OSM to mean some implied given semantic, which in my opinion, they shouldn't do. So it could be revealing. Here goes: any given way should

Hi Cleary, Two points: Paint isn't a barrier. Vehicles can, and do, traverse over paint; it's legal in many cases if there is a road blockage, for example. Being unable to change lanes doesn't make a single road into two roads. If I can't merge left then I'm not travelling on a different
