Hello, I thought of another option to make sure that dfrouter only creates vehicles for routes that end at sink detectors: delete all unwanted routes from the route file. I can manage to do this, but the question is how to provide an existing route file to dfrouter as input? I would expect the behavior to be similar as for the detector definition file: dfrouter does not recompute detectors that are already given. A similar option exists for routes: "--revalidate-routes". However, if I do not set this option and I provide an existing route file to dfrouter to save to, then it adds the routes again that I just deleted. Is this intended or is it a bug?
So is there are way to make sure dfrouter only computes traffic for the routes given in a route file, without recomputing / adding routes?
