But what if there are no crossings marked? Do we have to invent crossings then ? (e.g. near each junction) It is not uncommon to have such a network of sidewalks without "zebra"-crossings. People are allowed to cross everywhere then. There isn't even always a lowered kerb for people in wheelchairs. If the are lucky, they can use the connection of a driveway with the street, as those usually have a lowered kerb. m. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
