For the carFlagEncoder, the direction of a way is considered. However, how is the tag oneway = yes used in the algorithm? Is it during the weight calculation or any other part of the code? I am unable to find the relevant code dealing with the direction information of a way so that during the car navigation, the right route would be chosen.
It is handled during import also from the CarFlagEncoder. Or have a look into the DataFlagEncoder which is more flexible and you can customize your route preferrences per request (if CH is disabled)
If CH is disabled, how can I set my weighting? It the configure file, the weighting is set as
prepare.ch.weightings= fastest, which means the CH has to be enabled for this setting, right?
You can specify it per request, e.g. in the URL via “&weighting=fastest” or set this parameter in the hints.
