Experience with different routing solutions show that THEY have a first shot heuristic to find those short snippets. Most others dont. In the end its a heuristic - And as he says - commercial data providers do tag those snippets as such - why dont we? A heuristic always breaks on some occasions and we have no solutions.

From a legal perspective they are not something different ;) Motorway might be something special - But tertiary_link, primary_link, secondary_link are not special. In the dark ages of OSM somebody overloaded the highway type with attribution.

Re: [Tagging] Concrete kerbs in highway
Going with the theme of lazy wins out, having to convert a way into a dual carriageway is a pain. That is why using the tag kerb=center would 1) tell routing engines that left turns are not permitted and 2) possibly render more accurately. Dual carriageways renders [1] as if there is median when in fact it is only a kerb. This process could be expanded to include Jersey barriers. An alternative could be barrier=center/left/right, barrier=kerb/Jersey_barrier [1] https://www.openstreetmap.org/#map=17/48.43575/-122.33675 On Tue, Jun 23, 2015 at 5:35 AM, Paul Johnson wrote: > On Tue, Jun 23, 2015 at 2:42 AM, Martin Koppenhoefer < > dieterdre...@gmail.com> wrote: > >> >> 2015-06-23 1:58 GMT+02:00 Clifford Snow : >> >>> I have a question about how to tag concrete kerbs that prevent vehicles >>> from crossing.

Center kerbs are often for short distances to prevent left turns. The connecting streets could just be tagged with a no left turn. There doesn't seem to be interest in creating a tag kerb=center so one of the alternative will have to be the default. When I get some free time I'll try to add something to the wiki to help other mappers with center kerbs and barriers.
