As long as the figures that are entered are accurate you will get an accurate grade for the level of service for that particular roadway. Of course if you lie to it & enter figures you that you personally think are accurate because you would like them to be you will get a false grade. To get the accurate figures to enter contact the governing agencies that I mentioned in a previous response.
