Hi Jakob, I read the functioning of calibrator, what I understand is : the calibrator is put on the edge not at the jonction between edge. the file I find from the website of Montréal downtown is computing the number of vehicles crossing the intersection during a period. So, I can't use this information to major my flow by intersection? But, If I define each intersection as Taz and I try to use calibrator on this Taz, is it wrong strategy to generate real scenario ? please can you guide me to use the few information that I have to generate a scenario the closest to the real scenario. thank you. Lamia
