A SYSTEMS ANALYSIS FOR REAL-TIME FREEWAY TRAFFIC INFORMATION SYSTEM FOR THE INBOUND GULF FREEWAY CORRIDOR

THE TRAFFIC OPERATIONS ON THE INBOUND GULF FREEWAY WERE ANALYZED TO DETERMINE IF AN ACCEPTABLE LEVEL OF SERVICE WAS BEING PROVIDED WHEN AN ACCIDENT, STALLED VEHICLE, OR OTHER SIMILAR INCIDENT OCCURRED ON THE FREEWAY. THE MAGNITUDE AND FREQUENCY OF THE CONGESTION AND DELAYS EXPERIENCED DUE TO THE OCCURRENCE OF INCIDENTS WERE FOUND TO BE SIGNIFICANT. THE CONCLUSION WAS REACHED THAT THE NEED EXISTS FOR IMPROVING THE TRAFFIC OPERATIONS ON THE INBOUND GULF FREEWAY WHEN INCIDENTS OCCUR ON IT. THE DIVERSION OF TRAFFIC AROUND INCIDENTS ON THE FREEWAY WAS DETERMINED TO BE A FEASIBLE METHOD OF REDUCING THE CONGESTION AND INCREASING THE LEVEL OF SERVICE. TO ACCOMPLISH THIS OBJECTIVE, A REAL-TIME FREEWAY TRAFFIC INFORMATION SYSTEM IS REQUIRED. AS A FIRST STEP IN THE DEVELOPMENT OF A TOTAL CORRIDOR INFORMATION SYSTEM, A SMALL-SCALE, REAL-TIME, FREEWAY TRAFFIC INFORMATION SYSTEM IS RECOMMENDED FOR IMMEDIATE IMPLEMENTATION ON THE INBOUND GULF FREEWAY. THE OPERATIONAL RESULTS OBTAINED FROM THIS SMALL SYSTEM CAN BE USED AS INPUTS TO THE DESIGN OF THE RECOMMENDED TOTAL CORRIDOR SYSTEM. /TTI/
