DETERMINATION OF CHARACTERISTIC VALUES OF TRAFFIC VOLUME DATA

ERMITTLUNG VON KENNWERTEN DER BELASTUNGSGANGLINIEN

THE DIFFERING RATES OF UTILIZATION OF A TRAFFIC INSTALLATION DURING THE COURSE OF THE DAY ARE OF INCREASING SIGNIFICANCE TO THE ECONOMY AND THE QUALITY OF TRAFFIC FLOW. THE VOLUME DATA SHOULD THEREFORE BE CONSIDERED WHEN DIMENSIONING A TRAFFIC INSTALLATION. AS AN EXAMPLE, A JUNCTION WITHOUT TRAFFIC SIGNALS IS SHOWN IN ORDER THAT CHARACTERISTIC VALUES OF THE LOADING DATA CAN BE DETERMINED, FROM WHICH THE INFLUENCE OF THE VARIATIONS IN FLOW ON A PREDETERMINED CAPACITY CAN BE VERY PRECISELY UNDERSTOOD. IN REGARD TO EFFICIENCY, THE RECORDS OF THE MINUTE BY MINUTE LOADING CAN BE PRECISELY CHARACTERISED BY TWO VALUES: BY THE TRAFFIC INTENSITY IN THE DESIGN PERIOD OF TIME AND BY THE STANDARD DEVIATION OF THE MINUTE LOADING IN THIS INTERVAL. THE LENGTH OF THE DIMENSION PERIOD SHOULD BE SO CHOSEN THAT THE EXPECTED VALUE OF THE MAXIMUM MINUTE LOADING IN THIS INTERVAL DOES NOT RISE ABOVE DOUBLE THE VALUE OF THE AVERAGE MINUTE LOADING.
