The change is usually on the order of single digit percent per year, making even a decade old estimate much more representative than "heavy". Seriously, "traffic=trunk" obviously means nothing if we cannot agree on what "highway=trunk" means.
Ok, look here: https://www.openstreetmap.org/#map=16/50.3124/13.8720 The highway=trunk section is a bypass built to motorway specification. It is not even a motorroad, because it is so short, but the change in the character of the road is immense - it goes from 2 lanes to 2+2 lanes with a median, gets wider borders, no pedestrians, cyclists or agricultural vehicles allowed... The fact that it is drawn as a trunk road hints at all these changes. On 23 February 2018 at 23:18, Fernando Trebien <fernando.treb...@gmail.com> wrote: > Wouldn't the estimate change often?
