THE GEOMETRIC STRUCTURE OF AN OPTIMAL TRANSPORT NETWORK IN A LIMITED CITY-HINTERLAND CASE

WITHIN AN EXPLORATORY CONTEXT, A THEORETICAL FRAMEWORK FOR DETERMINING THE "OPTIMAL NETWORK" DESIGN FOR A GIVEN, LIMITED AREA IS DEMONSTRATED. THE TERM "OPTIMAL NETWORK" AS USED HERE REFERS TO THE MINMUM TOTAL FLOW COST NETWORK FOR THE GIVEN AREA, WHERE TRAFFIC FLOWS MAY ORIGINATE FROM ANY POINT WITHIN THE AREA. A LIMITED CITY-HINTERLAND CASE HAS BEEN SELECTED FOR ANALYSIS. ESSENTIAL COMPONENTS OF THIS REGIONAL LEVEL ANALYSIS COMPRISE A WELL-DEFINED RECTANGULAR AREA, A FOCAL POINT LOCATED CENTRALLY AT ONE EDGE OF THIS RECTANGLE, AND A TRUNK ROUTE PASSING THROUGH THROUGH THE POINT AND BISECTING THE RECTANGULAR HINTERLAND. THE PARAMETERS ARE: THE WIDTH AND THE BREADTH OF THE RECTANGLE, THE OPTIMUM ANGLE AT WHICH THE TRAFFIC FLOW THAT IS OFF THE NETWORK ENTERS THE NETWORK, THE SPACING INTERVAL BETWEEN THE PARALLEL SECONDARY ROUTES BRANCHING OUT FROM THE MAIN TRUNK LINE, AND THE ANGLE BETWEEN THE SECONDARY ROUTES AND THE MAIN LINE. IF ALL ALTERNATIVE GEOMETRIC NETWORKS COULD BE DEFINED BY SIMILAR SETS OF PARAMETERS, A GENERAL METHOD OF ANALYSIS COULD BE DEVELOPED. /AUTHOR/
