strange travel time result for hiking #762

Open pi3141 opened 11 months ago

pi3141 commented 11 months ago

Trip duration calculation give me unrealistic results for hiking profile. For example, a 450 m climbing on a 3.5 km distance give me a trip duration of 1 hour and 6 minutes. When I made the calculation with DAV standards, I have 450 / 300 + 3.5/4 × 1/2 = 1 hour and 56 minutes (which seems more realistic). Is it possible to edit parameters for trip duration calculation ?

Komoot estimates the travel time for this route as follows:

Fitness Travel time
Untrained 1 hour and 56 minutes
Average 1 hour and 39 minutes
In Good Shape 1 hour and 23 minutes
Athletic 1 hour and 06 minutes
Pro 50 minutes

Not that I know of, but I agree that it would be nice if it were configurable.

You can add assign maxSpeed = 3.4 to your profile to get to your desired travel time of 1:56h.

Currently Tobler's hiking function is used in footMode, where maxSpeed is achieved at -2.86° slope. If you know of a better model, I'd suggest opening an issue in the BRouter repo. See also discussion of corrections for Naismith's rule.
