Why not ask your question on the new OpenStreetMap Community Forum?

Geotab is a telematics software that uses OpenStreetMap. We noticed that recently a lot of side roads in the state of Missouri have had their speed limit changed to 25 mph when they should be 55mph. This is causing a number of problems for the system that tracks if drivers are speeding or not.

Does anyone know of a recent update in the last week or so would have caused this?

Can you link to an OSM object that was changed?

I'm not sure how to link OSM objects but here is one of the streets in question. alt text

It is W Belle Center Rd in Joplin, Missouri. Was changed to 25mph and should be 55.

Looks like my image didn't come through. The section of road would be on W Belle Center Rd between N Central City Rd and N Schifferdecker Ave.

https://www.openstreetmap.org/way/42707062#map=14/37.1010/-94.5714 was last changed 2 years ago. If you click on that link, you can see the person who last edited it and even contact them.

Hmm, that's interesting. You can easily see several 55mph signs on Google Street view and this road definitely was set to 55 in our system until recently.

We can't use Google Street View as a source for licensing reasons (but alternatives exist).

With regard to the "recent change", are you sure the the speed limit that you are seeing is sourced directly from OSM?

It looks like they also get data from HERE WeGo. This must be where the problem is. Also, how do I select a road segment and link it like you did above?
