TWO METHODS OF ECONOMIC EVALUATIONS ARE DESCRIBED: A NORMAL METHOD IN WHICH THE PLANNER BOTH MEASURES AND EVALUATES THE EFFECTS OF ROAD INVESTMENT AND IN WHICH THE PROFITABILITY OF THE INVESTMENT CAN BE EXPRESSED AS AN ECONOMIC INDEX; AND THE METHOD OF BENEFITS AND DISBENEFITS IN WHICH THE PLANNER ONLY MEASURES THE EFFECTS OF ROAD INVESTMENT IN QUANTITATIVE TERMS BUT SUBMITS THE VALUATION OF THE EFFECTS TO DECISION-MAKERS. THE PRESENT PRACTICE OF ROAD PLANNING IN FINLAND AND THE PRINCIPLES FOR THE APPLICATION OF ECONOMIC CALCULATIONS ON VARIOUS LEVELS OF PLANNING ARE PRESENTED. ECONOMIC CALCULATIONS ARE DEFINED AS THE SELECTION OF DESIGN STANDARDS, THE DETERMINATION OF THE ECONOMIC JUSTIFICATION OF PROJECTS IN GENERAL, THE PROGRAMMING OF INVESTMENTS, AND THE DETERMINATION OF THE ECONOMIC JUSTIFICATION OF AN INVESTMENT PROGRAM OR SPECIALLY LARGE INVESTMENTS. THE METHODS AND PRINCIPLES USED IN EACH CASE ARE DESCRIBED AND THE IMPORTANCE OF STANDARDIZATION IS EMPHASIZED.
