OPTIMIZATION METHODS IN HIGHWAY PLANNING /IN PORTUGUESE/

THE METHOD TO BE USED IN ESTABLISHING AN OPTIMUM POLICY FOR THE APPLICATION OF RESOURCES IN HIGHWAY NETWORKS IS PRESENTED. THE METHOD IS BASED ON THE FORMULATION OF A LINEAR PROGRAMMING MODEL. THE INPUT VARIABLES ARE OBTAINED FROM THE FOLLOWING QUANTITATIVE INFORMATION SOURCES: (1) TRAFFIC FORECASTING FOR THE NETWORK, (2) ANNUAL COST PER VEHICLE AND COST PER NETWORK HIGHWAY, AND (3) CONSTRUCTION COSTS FOR THE ALTERNATIVES CORRESPONDING TO EACH NETWORK HIGHWAY. THE MODEL CONSTRUCTION REQUIRES THE KNOWLEDGE OF THE LIMITATIONS IMPOSED BY REGIONAL PLANNING AND BY THE GEOGRAPIC STRUCTURE. THE NETWORK GEOMETRY IS REFLECTED IN THE MODEL BY AN INCIDENCE MATRIX THAT SHOWS THE POSSIBLE JOURNEYS. THE NETWORK IS DEVELOPED IN DIFFERENT STAGES UNTIL THE OBJECTIVE DEFINED BY REGIONAL PLANNING IS MET. THE APPLICATION OF THIS METHOD WILL INDICATE THE BEST WAY TO INVEST IN THE NETWORK AND WHICH STAGES WILL REDUCE THE OPERATING COSTS OF THE NETWORK TO A MINIMUM. THIS METHOD MAY BE APPLIED TO THE ANALYSIS OF NETWORKS MUCH MORE COMPLEX AND WITH OTHER LIMITATIONS. /RRI/
