A SYSTEMATIC METHOD OF FORECASTING FUTURE HIGHWAY TRAFFIC

METODOLOGIA SISTEMATICA DI PREVISIONE DEL TRAFFICO STADALE FUTURO

This article presents a method for forecasting the future traffic along a generic arterial road, having first determined the law of traffic growth relative to the territorial area containing the highway in question. As a example the method is applid to a highway in the province of Milan, Italy, and the resulting linear solution is based on the flow-density dependence of the area traffic growth. Tables show saturation limits, km (veh/1000 inhabitants), for the province of Milan, obtained by increasing amplitude subseriation from 1950-1974; and traffic density (veh/1000 inhabitants) forecasts; calculated with relative deviations and percentage increases. The upper and lower density limits of regional traffic growth are shown in a graph. A flor chart is presented for the computer calculation of the correlation between traffic flow and density. /TRRL/
