OPTIMIZATION TECHNIQUES APPLIED TO IMPROVING FREEWAY OPERATIONS

THIS PAPER DESCRIBES OPTIMIZATION TECHNIQUES WHICH HAVE BEEN DEVELOPED AND APPLIED FOR EVALUATING FREEWAY OPERATIONAL IMPROVEMENTS SUCH AS REDESIGN AND/OR RAMP CONTROL STRATEGIES. THE PAPER HAS FOUR MAJOR PARTS. A DETERMINISTIC MACROSCOPIC SIMULATION MODEL IS DESCRIBED WHICH PREDICTS THE TRAFFIC PERFORMANCE ON A DIRECTIONAL FREEWAY AS A FUNCTION OF FREEWAY DESIGN AND TRAFFIC DEMAND PATTERNS. TWO DECISION MODELS ARE PRESENTED WHICH AUTOMATICALLY WORK WITH THE SIMULATION MODEL TO SELECT OPTIMUM REDESIGN AND/OR RAMP CONTROL STRATEGIES. FINALLY, A FREEWAY CORRIDOR MODEL IS DESCRIBED. EMPHASIS IS GIVEN TO THE STRUCTURE OF THE MODEL AND TO THE FIRST STEP IN THE DEVELOPMENT OF THE FREEWAY CORRIDOR MODEL WHICH IS A MAJOR ARTERIAL STREET MODEL. /NTIS/
