Do OSM.PBF files provide information about the altitude ? For bicycle travelling the 3rd dimension is much more important than for motorcars or pedestrians.
It happened to me GPSMid offered in city navigation a path I would choose as pedestrian, but never as a biker. It lead me across an avoidable big hill. Interesting was none of 5 bicycle routing options by www.openrouteservice.org ( based on OSM ) offered that rudiculous way across the hill. Even the shortest way has chosen another, much faster one.
( as reference, GPSMid map was based on Czech_republic.osm.pbf , city map of Brno,
route compared was from Technicka to Kridlovicka street - exact points as below.
GPSMid was routing me across the "Zluty Kopec" hill.
start point is Pos@: 16.577932 49.225774
end point is Pos@: 16.594927 49.188652
All its routes including shortest one went estern of the hill.
P.S.: BTW, is possible routing algoritms of ORS are available ? ( Shortest, Safest, MTB, Racer, PreferredCycloWays/-routes )
Note that for some reasons OSR has some problems this morning….
I could not find the hill quickly so I could not check the way type that the path is.Maybe ors never routes on this way type by bicycle? Afaik osm.pbf does not contain altitude data.
I focused the start area more closely to the Zluty Kopec ( see below ) to persuade ORS to use the same way as GPSMid. Now ORS original routes were less optimal, comparing to route of GPSMid.
ORS resisted to go across the hill for long time - yet here
but finaly ORS made the same route across the hill as GPSMid did, when I pushed the start .
note that the way between previsou and final start position is routable by ORS.
So it seems to be matter of preferences and routing algorithm.
