A SIMULATION SYSTEM FOR STUDY OF TRAFFIC FLOW BEHAVIOR
DURING THE PAST DECADE A RAPID INCREASE IN THE DEVELOPMENT OF COMPUTING TECHNOLOGY HAS INCREASED INTEREST IN THE USE OF DIGITAL COMPUTERS AS A MEANS OF SIMULATING TRAFFIC FLOW. THE DEVELOPMENT OF SIMULATION CONCEPTS HAS ADVANCED FROM SIMPLE DETERMINISTIC MODELS WHICH CONSIDERED ONLY A FEW ELEMENTS OF THE DRIVER, VEHICLE, AND ENVIRONMENT TO STOCHASTIC MODELS WHICH INTRODUCE COMPLEX INTERACTION BETWEEN THE VEHICLE- DRIVER AND THE PHYSICAL ENVIRONMENT. ONE OF THE MAJOR PROBLEMS IN INTRODUCING SIMULATION TECHNIQUES AS A TOOL FOR THE STUDY OF DESIGN AND OPERATIONAL PROBLEMS ON HIGHWAY SYSTEMS IS THE DIFFICULTY ENCOUNTERED IN PROGRAMMING SIMULATION PROBLEMS WHICH CAN BE LEARNED WITH THE EXPENDITURE OF A LIMITED AMOUNT OF TIME. THE AUTHORS REPORT THE DEVELOPMENT OF A SIMULATION SYSTEM THAT UTILIZES A LANGUAGE CALLED SIMCAR WHICH HAS A GENERALIZED CAPABILITY FOR PROGRAMMING TRAFFIC SIMULATION PROBLEMS. THE SOURCE LANGUAGE CLOSELY RESEMBLES THE LANGUAGE USED BY DESIGN AND TRAFFIC ENGINEERS. USING THE SIMCAR LANGUAGE, THE GEOMETRY OF A HIGHWAY, THE CHARACTERISTICS OF VEHICLES AND DRIVERS AND THE CONTROL ELEMENTS MAY BE COMPLETELY SPECIFIED WITH ONLY A LIMITED AMOUNT OF SPECIALIZED TRAINING IN COMPUTER PROGRAMMING.
