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
Re: [OSM-dev] Just Joined List
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.

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.

Re: [OSM-dev] Just Joined List
This definitely is something you should NOT do on the main API. That API is for people editing and improving the map, not for using the data. Download an extract for your region and set up a server with it. Then figure out how to go about finding the nearest way to your GPS position (most likely using PostGIS).
