Hey Jakob, many thanks for the fast response. That would be a nice way if I can define the vType for each vehicle, but my problem is, that I have thousands of vehicle from the same model and with the same CFM and I don't know which is leading and which is following.
So I thought, I define for each vehicle two max speeds (actual I make this with one from the vType and one as a param in the CFM) and the vehicle decided by self which max speed it should choose based on the return of: " veh->getLeader()". This works fine if max Speed for following mode is < max speed of vehicle type, but bad if it is the other way round. Then it uses every time the max speed from the vType (Dose SUMo checks on the other point also the vType max speed and not only in the CFM?). Thanks and kind regards, Jonas 2017-08-20 10:57 GMT+02:00 Jakob Erdmann <namdre.s...@googlemail.com>: > Hello, > the maximum speed of a vehicle is defined in its vType.
