I once mapped a traffic choker such as the one shown below as three ways one for the main part of the highway and two highway=cycleway. Given the topology of such features, mapping them this way is inaccurate (the cycleways flare away from their true line). In my mapped example there is also a pedestrian crossing on a road table in the middle of the chicane. So they can be somewhat complex. Is there any quicker/simpler way of mapping such detail, without losing the information from the 3-way approach?

I would not split a road into multiple ways for such a small section. This is actually quite similar to any other highway=crossing + crossing=island - and these are also just a single node in the way despite the (extremely short) physical separation. The only additional feature here is the unusual distribution/bundling of the lanes. The fact that there are crossings is imo immaterial as to how the road lane infrastructure is mapped, and not the question I asked. I see a hint in your answer that use of relevant lane tags might avoid the need for a 3-way solution.

Chokers like this, but without the pedestrian crossing, are quite common around where I live. I always map them as a single point in the road with the tag traffic_calming=choker. They are a choker for both cars and for cyclists. (They are at least with the amount of cyclists and mopeds on the road in The Netherlands.) Adding the crossing tags to the same node isn't a problem, as all the tags have a different key.

I'd like to see a photo, but this isn't a choker for cyclists, the whole point of the 'gutters' is not to penalise cyclists at the choker. Whether it works as such is a different matter.

No it's not. All good intentions by people never riding a bike are moot, when the net effect is something completely different for people who actually do ride a bike.

In that example I would actually map it as three ways, because there are three ways separated by barriers. Someone using the crossing would have to negotiate 3 different streams of traffic. It looks funny on a map that maps wide roads as thin lines - a few people have had a go at mapping normal roads as areas, but not always with a great deal of success. |

This may help you as somone has a standard tag for them (near the bottom of the page) http://wiki.openstreetmap.org/wiki/Key:traffic_calming I areaised a few recently here:- https://www.openstreetmap.org/way/368797281#map=19/51.74765/-1.22939&layers=D I hope that helps -Govanus |
