ELECTRONIC CALCULATION AND OPTIMIZATION TECHNIQUES. APPLICATIONS TO THE FIELD OF HIGHWAY DESIGN /IN FRENCH/

THE INCREASING USE OF COMPUTERS IN HIGHWAY DESIGN IN A LARGE NUMBER OF COUNTRIES AND PARTICULARLY IN FRANCE IS DISCUSSED. THE EARLY HOPES OF USING OPTIMIZATION TECHNIQUES IN CONJUNCTION WITH COMPUTERS FOR SOLVING PROBLEMS OF HIGHWAY DESIGN WERE NOT ALWAYS FULFILLED AS THE COMPLEXITY OF THE INTERVENING FACTORS WAS OFTEN UNDERESTIMATED. A PROGRESSIVE APPROACH EVOLVED BY THE SETRA IS DESCRIBED. THE FIRST TWO LINKS OF THE METHOD HAVE BEEN ESTABLISHED; THEY CONCERN EARTHMOVING WHICH IS REDUCED TO A PROBLEM OF ORTHODOX TRANSPORT, AND RESEARCH INTO THE OPTIMUM LONGITUDINAL PROFILE AFTER THE HORIZONTAL ALIGNMENT HAS BEEN DETERMINED. A DYNAMIC METHOD IS USED WHICH TAKES INTO ACCOUNT A RELATIVELY COMPLEX COST FUNCTION PARTICULARLY CONCERNED WITH EARTHWORK, CROSSINGS, AND ROAD USERS' DEMANDS. /LCPC(A)/RRL/
