It depends on what map is supposed to display. In this case I want a city-wide map with oneway roads that are potential candidates for designating them as contraflow for bicycles (all oneway roads without oneway:bicycle=no that are not a dual carriageways). I implemented it using dual_carriageway=

Road itself is not oneway as it has two one-way carriageways in opposite directions. Carriageways are mapped in OSM as separate one-way ways. 2014-07-10 21:32 GMT+02:00 John F. Eldredge : > I am confused. You state that the road is divided into two carriageways, > that neither carriageway is one

I am confused. You state that the road is divided into two carriageways, that neither carriageway is one-way, and also that each carriageway is one-way. How can a given carriageway be both one-way and not one-way at the same time? On July 10, 2014 5:20:16 AM CDT, Mateusz Konieczny wrote: > I

I think I just ignored very short links, so I don't think it would help in that case. Very roughly, I calculated the bearing of each way, and matched up ones that were within a few metres laterally and a few degrees of 180deg of each other. Richard On Thu, Jul 10, 2014 at 11:33 AM, Mateusz Koni

I am thinking about marking tagging roads with separate carriageways. I want to create map with oneway roads, but in OSM data roads with separate carriageways that are not oneway are frequently represented as separate ways, both tagged as oneway. Adding tag that that would describe way as part of
