INVESTIGATION INTO THE ESTABLISHMENT OF DIMENSIONAL LOADING

UNTERSUCHUNGEN ZUR FESTLEGUNG VON DIMENSIONIERUNGSBELASTUNGEN

The fluctuating utilization rate of a traffic facility during the course of a day is of considerable significance for its economics and for the quality of the traffic movement. The loading curve should therefore be the subject of a different form of consideration from that previously given when designing traffic installations. Since not all the information, which is contained in the curve, is of equal significance when designing, it is possible to reduce it to the essential requirements. As an example an uncontrolled intersection is shown, whose characteristic value can be determined from the traffic flow curve and from which the effect of the flow variations upon a predetermined target value (linked to the efficiency level) may be precisely understood. The determination of the efficiency level follows for the free moving traffic by means of a closed solution, for the partially restricted moving traffic with the help of a simulation of the flow. With reference to the efficiency the curves of the loadings per minute are characterised clearly by two values; from the traffic flow in the design period time interval and from the standard deviation of the loading per minute during this interval. The length of the design period time interval may be selected so that the expected value of the maximum loading per minute within an interval does not exceed double the value of the average loading per minute. /TRRL/
