Hi @mbenkert ,
there are a few posts that deal with in a bit more detail this e.g.:
In order to better control speed limits and other routing prioritization I had to create my own FlagEncoder called MyHeavyVehicleFlagEncoder (a copy of HeavyVehicleFlagEncoder for the moment until restrictions work) and added a new DRIVING_MYHGV constant in RoutingProfileType (value of 77 not used before). I also adapted the code so the generation produces the graph folders.
Until here everything looks great and i was able to have two directory in my graphs folder after the generation is done: …
If you run your own, you will be fine with adjusting existing values.
for hiking sac scale adjust:

which waytypes are usable is definde in the getAccess method in those files.
