1. Yes. The number of inserted vehicles should be the same for the same input volume 2. Yes. The option was set correctly (subsections like <input> are ignored anyway).
Please provide the input files for the two test cases 1500/0 and 1500/500 so I can investigate the cause of the flow reduction. regards, Jakob Am So., 26.
