thats i great Debug view i had look some days ago already.

Looking again - Is there a possibility to change the average
speed but not the maxspeed?

The Road in question here:

http://map.project-osrm.org/debug/#17/51.90112/8.36067

Is listed as 67km/h - The problem is that the maxspeed
on that road is indeed 70km/h but there is a traffic light
switching which only allows 60km/h. There is also signage
saying so:

Maxspeed:

On the very right side "Grรผne Welle bei 60Km/h":

That means the average travel speed would be much more like 55km/h or
something.
