Good afternoon Peter,
thank you for precise explanation.
As I see, end point is on break between both paths (little move cause difference). I’ve compared results of GraphHopper to Google Maps and most used maps in Czech: mapy.cz . Both prefer path “over city” as faster.
I have just compared speed values of GH with my own track records from Locus testing and speed over city is correct! Maybe even little optimistic. For exactly this segment, my recording has average 6:20.
So problem seems to be optimistic speed in south/west path over villages Popovice and Polerady. I may confirm that drive here is a lot slower. Mainly this segment . I made this topic mainly because of my wife who ride yesterday in dark back home exactly by GH and this road was by her only grave. So she had to return back together with angry whispering on my and your head
Anyway, sorry for longer post, thanks for explanation and maybe consider improving time estimates on tertiary roads without exactly defined surface. Thanks!
Just for your information
GH (over city): 9.1km, 12min
GH: 9.9km, 11min
google (over city): 9.1km, 11min:
google (same path as GH): 9.9km and even 16min
mapy.cz (over city): 9.1km, 10 min
mapy.cz (same path as GH): 9.9km, 14min
