In the UK we have lots of the latter, but it appears that we also have some accidentally mistagged as the former.
There are genuine guided busways of course (the Cambridge / Ely one is probably the most famous) but some of the others I am suspicious about - like the one in Leeds.
Does anyone know if any of these are definitely mistagged?
There are also a handful of what should be highway=busway, tagged as highway=service + access=no + bus=designated for the same reason as above, to make them display on carto. For example Luton-Dunstable busway which has become an edit war at this point Changeset: 177190730 | OpenStreetMap (this one does allow cycling which complicates things).
Thereâs a bus-only road in Bristol which Iâve tagged as part bus guideway, part busway, which of course looks silly on carto, but is correct. Way: 517659892 | OpenStreetMap
Itâs mostly guided, but some sections are unguided for example around Luton station. The example changeset I shared changed highway=busway to higway=unclassified because âhighway type âbuswayâ becomes invisible on map and does not allow bus access. This affects public bus map data that is based on OSM.â I think there are also some OSM-based games that donât support certain busway tags (City Bus Manager?), but donât quote me on that.
