It seems to have gone viral at some point, as they had to switch to their own Overpass instance to handle the load. -- ___ dev mailing list dev@openstreetmap.org https://lists.openstreetmap.org/listinfo/dev

Hi Claude, I would recommend a more sophisticated approach using map matching, otherwise how could you be sure which of the many nearby roads at a crossing is the one the vehicle drives through? There are many services and open source software that implements this, so I won't recommend just ours ;) Regards Peter Am 18.04.19 um 13:41 schrieb Rory McCann: > This can be done with the Overpass API, not the OSM editing API > > way(around:25,LAT,LON)["maxspeed"];out; > > This should give you all ways within 25 m of a point with the maxpseed > tag.

I think that is underplaying things... I don't speak for the overpass maintainers but I can't imagine that hitting it every three seconds for every vehicle that you are tracking is going to go down well - at least if you are tracking any even vaguely significant number of vehicles. If you are building a business on this and selling this to people as a service then you really should be looking to run your own overpass instance or something.

Re: [OSM-dev] Just Joined List
This can be done with the Overpass API, not the OSM editing API way(around:25,LAT,LON)["maxspeed"];out; This should give you all ways within 25 m of a point with the maxpseed tag. Be warned though: Most of the main overpass servers do have access limits, and building a business relying on things that can be shut off without warning might not be a good idea.
