I use the "Routing Web Server" application from graphHopper. In the "config-example-properties" file I can only use a car as vehicletype. But I need a profile for trucks.
In the demos I can see, that they use also trucks. How I have to change the config-files, that I can activate a truck profile?
If you refer to the bus and truck profiles here then you have to build them on your own or buy the commercial offering which is an add-on to the open source routing engine.
BTW: In the near future building custom profiles will be a lot easier. Note: I'm the author.
