Dear Manh Do Van, OpenStreetMap does not have any traffic demand data that I know of. What happens with the osmWebWizard and randomTrips.py is that it assigns trips from and to random locations (hence the name). It is possible to give higher probability to faster / wider roads or the network fringe but it is still random. Concerning your third question, there are a variety of simulated detectors in sumo, see https://sumo.dlr.de/wiki/Simulation/Output
