Measurements to define relationship between Traffic Volume and Traffic Conditions in Hungary

The traffic volume (expressed either in Vehicle/hour or in Passenger Car Unit/hour) resulting from traditional traffic counts is only an approximation to reflect the quality of the traffic flow. The drivers appreciate traffic conditions considering and evaluating the situation in their immediate neighbour-hood. These conditions can be more accurately represented by a fictive traffic volume calculated on the base of five minutes long intervals, the average speed and the active driving speed as well as that of the instantaneous traffic density. The level of services associated to different traffic conditions can be defined using these parameters.
