Using electronic computer techniques for traffic assignment and economic analysis, the author attempted to determine the optimum spacing of interchanges and grade separations between a freeway system and arterial, collector and local street systems. The criterion function used to determine the optimum spacing was the minimization of the total annual transportation cost. Eleven spacing schemes or networks were analyzed. The author concluded that the selection of the optimum spacing must be based on criteria other than economic analysis alone.
