working method

Parameters:

	vehicleId	list of unique ids of vehicles in sumo simulation
	wantedVehicle	list of filtered vehicles ids
	vehicleFirstOcc	map: vehicle id -> first occurence of vehicle in sumo
	vehicleLastOcc	map: vehicle id -> last occurence of vehicle in sumo
	begin	sumo time at which ns2 should start to simulate
	end	sumo time at which ns2 should stop to simulate
