EMPLOYMENT OF PROFITABILITY ANALYSIS IN EVALUATION OF INTERVENTION PLAN ON ROADS INFRASTRUCTURES

UTILIZZO DELL'ANALISI DI REDDITIVITA' NELLA VALUTAZIONE DEI PIANI DI INTERVENTO NEL SETTORE DELLE INFRASTRUTTURE STRADALI

IN THE FIELD OF ROAD INFRASTRUCTURES INVESTMENTS ARE MADE IN ORDER TO IMPROVE THE QUALITY OF ROAD TRANSPORT. THE IMPROVEMENT CORRESPONDS TO A DECREASE OF VEHICLE OPERATING COSTS AND TRAVEL TIME AND TO INCREASE OF COMFORT.IT IS THEREFORE NECESSARY TO FIND AN INTERVENTION PLAN INVOLVING NOT ONLY NEW INFRASTRUCTURAL PROJECT BUT ALSO REHABILITATION OF EXISTING ROADS THROUGH SMALLER PROJECTS AND SUITABLE MAINTENANCE PLANS. BUDGET ASSESSMENT AND SCHEDULING SHOULD IN FACT CONSIDER DESIGN, PROJECT MAKING, MANAGEMENT AND MAINTENANCE AS A SUCCESSION OF STEPS OF A SAME PROCESS. AN INTERVENTION PLAN APPRAISAL, THAT SHOULD SELECT THE MOST FEASIBLE PLAN GIVEN THE ENVIRONMENTAL AND ECONOMIC CONDITIONS, MUST TAKE INTO ACCOUNT THE EFFECTS OF ROAD-VEHICLE AND ROAD-ENVIRONMENT INTERACTION AFTER THE PROJECT COMPLETION COMPARED TO A "NULL PROJECT" SITUATION (IN WHICH, FOR EXAMPLE, ONLY ROUTINE MAINTENANCE IS PRODUCED). ONCE ALL THE ELEMENTS, WHICH FORM BENEFIT AND COSTS DUE TO INFRASTRUCTURE MAKING, MANAGEMENT AND USE, ARE CONSIDERED, IT IS POSSIBLE, THROUGH EXISTING SIMULATION MODELS, TO CARRY OUT THE COST-BENEFITS ANALYSIS OF THE PLAN AND TO TEST ITS SENSITIVITY THROUGH SOUND SCENARIO VARIATIONS. THE PLANNER'S ATTENTION SHOULD NOT BE SO FOCUSED ON SIMULATION ITEMS OF SIMULATION MODELS BUT RATHER ON THE STUDY FOR GEOGRAPHICAL-ECONOMIC SYSTEM IN WHICH THE PLAN IS APPLIED, IN ORDER TO COLLECT REALISTIC DATA AND, ABOVE ALL, IN ORDER TO IDENTIFY REALISTIC SCENARIOS FOR THE ANALYZED PERIOD.
