[OSM-talk] Proposed automated edit of some barrier=kerb kerb=raised nodes (forum crosspost)

[osmuser63783]

Please let me know if there are any unresolved concerns about this proposed edit. If there are no objections I would like to run it this weekend.

List of example nodes that I'm proposing to edit: https://community.openstreetmap.org/t/proposed-edit-of-some-barrier-kerb-kerb-raised-nodes/98038/13

Example changeset: https://www.openstreetmap.org/changeset/135319439

Of course highway=crossing kerb=* is perfectly acceptable tagging, I am not proposing any changes related to that. The vast majority of nodes that I am proposing to remove barrier=kerb from do not have highway=crossing.

The developer of StreetComplete did not want to add a highway=crossing tag, because there are people who say that highway=crossing should only be added when there is some infrastructure. It would equally be wrong to add crossing=no because that suggests that it is impossible or illegal to cross. Therefore, StreetComplete only adds kerb=raised.

So barrier=kerb on roads with any other values of kerb=* in my view need to be reviewed on a case by case basis.I also imagine that to reach some highway=service you have to drive over a kerb. So these would also need to be reviewed case by case.

> The cases where I am sure the barrier=kerb is wrong are those where StreetComplete added kerb=raised and then later someone added barrier=kerb in iD, following the validator suggestion. kerb=raised is the only value of kerb= that StreetComplete adds without a crossing tag. It also doesn't ask this quest about service roads or motorways (I checked the code), so there is no reason to include this in my initial Overpass query that identifies candidate nodes.
