Please check the result returned by subscribeContext against the list of vehicles returned by traci.vehicle.getIDList. There may also be a mismatch due to 'teleporting' vehicles. They are still listed as 'active' in the vehicle counter but are not on any lane and thus not returned by the subscription. You can track telepoorts by computing a running sum of the values returned by traci.simulation.getStartingTeleportNumber and traci.simulation.getEndingTeleportNumber
