Thanks for reaching out! ❤

You will find an overview of the available config parameters for routing profiles at [ors.engine.profiles.\<PROFILE-NAME\>.build | openrouteservice backend documentation](https://giscience.github.io/openrouteservice/run-instance/configuration/engine/profiles/build).

To use the maxweight/-width/-height limits you might want to use the hgv profile. It’s also able to route over ways with OSM [`access=forestry`](https://wiki.openstreetmap.org/wiki/Tag:access%3Dforestry) once you specify `options.vehicle_type=forestry` in your query.

To enable routing over `barrier=sump_buster` you will need to edit the JAVA source files, as this is not something which can be done at the configuration level. As a starting point for your experiments you could take the [hgv vehicle profile](https://github.com/GIScience/openrouteservice/blob/main/ors-engine/src/main/java/org/heigit/ors/routing/graphhopper/extensions/flagencoders/HeavyVehicleFlagEncoder.java).

Last but not least, for modifying the default speed values, please have a look at:

> Hi @tgff, it seems changes in the FlagEncoder don’t really take effect, as it uses the speed values defined in ors-engine/src/main/resources/resources/services/routing/speed\_limits/car.json person_shrugging If you change the values there you should see an effect after removing & rebuilding the graphs.
