A STUDY OF THE OPTIMUM DISTANCE BETWEEN MOTORWAY ACCESS POINTS

STUDIO SULLA DISTANZA OTTIMALE FRA SVINCOLI AUTOSTRADALI

This study is an attempt to develop a generalised procedure for determining the optimum distance of motorway access points, given fixed characteristics for the motorway and well defined relations with the area surrounding it. The approach is based on the rate of immediate profitability of the road with reference to the first year of service, and the study determines: (1), the number of access points to be opened initially; and (2), how these may be increased with maximum convenience, as traffic increases over the years. /TRRL/
