THE HDM MODEL AS A SUPPORT INSTRUMENT IN THE ECONOMIC ANALYSIS OF ROAD NETWORK INTERVENTIONS

IL MODELLO HDM COME STRUMENTO DI SUPPORTO NELL'ANALISI ECONOMICA DEGLI INTERVENTI SULLA RETE STRADALE

INVESTMENT PLANS FOR REHABILITATION AND DEVELOPMENT OF A REGIONAL ROAD NETWORK MAY INCLUDE A SET OF PROJECT ALTERNATIVES WHICH MUST BE ACCURATELY APPRAISED AND COMPARED. A NECESSARY STAGE OF ECONOMIC EVALUATION OF PROJECTS IS APPRAISAL OF CAPITAL AND CURRENT COSTS DUE TO PROJECT FULFILMENT. THIS NEEDS TO QUANTIFY AND FORECAST THE CHANGES IN ROAD PHYSICAL CONDITIONS, CAUSED BY ENVIRONMENTAL AND TRAFFIC EFFECTS, YEAR AFTER YEAR DURING ITS TECHNICAL LIFE, AND THE EFFECTS OF ROAD CONDITIONS AND GEOMETRIC CHARACTERISTICS ON USER TRANSPORTATION COSTS. "HIGHWAY DESIGN AND MAINTENANCE STANDARDS" MODEL WOULD BE A PRACTICAL TOOL OF ECONOMIC EVALUATION OF INFRASTRUCTURAL AND MAINTENANCE PROJECTS IN THE ROAD FIELD. THIS ARTICLE DESCRIBES THE STRUCTURE OF THE MODEL AND THE DATA SETS NEEDED FOR APPLICATION. IT WILL THEN SHOW THE MAIN ASPECTS WHICH MAKE THIS MODEL MORE EFFICIENT, IN ITS PRESENT FORM, FOR ECONOMIC ANALYSIS OF PROJECTS IN DEVELOPING COUNTRIES (FOR WHICH IT WAS MADE) THAN FOR PROJECTS IN THOSE COUNTRIES, LIKE ITALY, WHERE THE ROAD SYSTEM IS MORE ARTICULATE AND TRAFFIC FLOWS ARE THE MAIN FACTOR OF EVERY PLANNING PROCESS.
