TRAFFIC MODEL FOR AUSTRIA. TOTAL MATHEMATICAL MODEL

项目名称：	TRAFFIC MODEL FOR AUSTRIA. TOTAL MATHEMATICAL MODEL
摘要：	THE EXPANSION OF COMPLEX TRAFFIC MODELS TO AN AREA THE SIZE OF AUSTRIA CREATES PROBLEMS, ALTHOUGH THE THEORETICAL PRINCIPLES REMAIN BASICALLY UNCHANGED. THE MATHEMATICAL MODEL HAS TO FULFIL THE FOLLOWING BASIC REQUIREMENTS: (1) COMPREHENSIVE DETERMINATION OF TRAFFIC (GENERATION, DISTRIBUTION AND DIVERSIONS); (2) OPTIMUM EVALUATION OF EXISTING SCIENTIFIC KNOWLEDGE IN THE FIELD OF TRAFFIC PLANNING AND SOLUTION OF SCIENTIFIC PROBLEMS NOT YET RESOLVED; (3) PRACTICAL APPLICATION; (4) ECONOMIC APPLICATION. IN CONTRAST TO THE REGIONAL MODELS THE FOLLOWING DIFFICULTIES HAVE TO BE OVERCOME: (1) BOUNDARY CONDITIONS; (2) GRADING OF THE INPUT FACTORS; (3) DIMENSIONING OF THE MODEL; (4) SCOPE OF RANDOM SAMPLE. THE PROCESS OF FORMING THE MODEL IS BEING UNDERTAKEN IN FOUR STAGES: (1) PROBLEM AND SYSTEM ANALYSIS; (2) SIGNIFICANCE ANALYSIS AND ABSTRACTING PHASE; (3) DEVELOPMENT OF THE MATHEMATICAL MODEL IN THE NARROW SENSE; (4) DEVELOPMENT OF A MEANS OF EVALUATING THE EFFECTIVENESS OF THE RESULTS OF THE MODEL.
