[OSM-talk-be] Changing default maxspeed for Brussels in 2021

[joost schouppe]

Hi Yves,

Sounds good. We'll need to update at least these pages:

https://wiki.openstreetmap.org/wiki/OSM_tags_for_routing/Maxspeed#Belgium
https://wiki.openstreetmap.org/wiki/Key:source:maxspeed#Belgium

Have you given it any thought how we might organize the update efficiently?
I thought perhaps the ways now tagged with source:maxspeed=[something
urban] could be bulk-edited after the change, but it looks like many of
those roads might actually change to explicitly signed 50 during the
transition. So I'm thinking we need to review ALL the roads with a maxspeed
again after the change. To do that, maybe we could take a dump before the
change and use that for some sort of mapping challenge, or add a tag to
indicate that the maxpseed should be reviewed (the risk being that people
might correct the maxpseed and not remove the tag).

Best
Joost
