Is it normal to see 4 relations for BW1 ?
I could see only 2 relations and 2 ways (highway=busway) including the string “BW1” in ‘name’
Yes, the two relations are OK, half-ways: they are tagged as PTv2 (public_transport:version=2) and represent the 'aller' et 'retour'
of the bus route. What’s missing: their ‘parent’ relation, the route_master relation.
Edit: add links to relations - Relation: BW1 Salmia 2-Omar Al Khayam (18041838) | OpenStreetMap and Relation: BW1 Omar Al Khayam-Salmia 2 (18041839) | OpenStreetMap
Thanks ; I’ve added r18783086
