GPS traces : Update frequency

Hello,

How often are the GPS traces updated ?
Here is an example where roadworks were ended in May but the GPS traces are still showing the road deviation that was made during those roadworks : https://www.waze.com/fr/editor/?env=row&lon=4.40753&lat=50.79536&layers=973&zoom=7

“Now and then” but don’t think there is some kind of regularity in them and of course also depends of how much GPS traces are available to put in place…

This is a big street.
There should be a lot of traces availables. And at least … mine !

I know little streets where I 've been driving for a year , still no gps traces …
