Hello,
which parameters do I have to set for the "BRouterWeb" in the profile eg: Hiking (Beta) (hiking-beta.brf ?) so that I can influence the travel time?

Thanks Achim

It very depends on transportation mode.

For foot profiles, time estimation is AFAIK hardcoded withing Brouter.

For car profiles, you can tweak kinematic model parameters, mostly max speed, car mass or perhaps engine power.

Bicycle profiles use their own kinematic model, with the most influential parameters the pedalling power (Watts) and the ( total ) mass. minor parameters are rolling and drag resistence coefficients.

See e.g.

I often use estimated total weight (my weight, bike weight, luggage weight)  and relatively low power like 85 W to estimate the effective travelling speed or ETA. 

Once personally tuned, it is quite reliable even for "expedition mode" on long distance trips with many breaks, with low effort on a loaded bicycle.
