OPTIMUM RAMP CONTROL FOR INCIDENT RESPONSE

THIS REPORT DISCUSSES A RAMP CONTROL SYSTEM RESPONSIVE TO FREEWAY INCIDENTS. THE OBJECTIVE OF THE STUDY IS TO OPTIMIZE OR MINIMIZE A WEIGHTED COMBINATION OF AFFECTED FREEWAY AND DIVERTED VEHICLES. THE MODEL OF QUEUE DYNAMICS USED WAS DEVELOPED IN EARLIER WORK AND IS OUTLINED IN THIS STUDY. THE CONTROL LAW RESULTING IS AN EXTREME SOLUTION (RAMP COMPLETELY OPEN OR COMPLETELY CLOSED), THE DECISION DEPENDING ON THE WEIGHT GIVEN TO DIVERTED VEHICLES AND ALSO ON MICROSCOPIC SYSTEM PARAMETERS. COMPARISONS AMONG CASES ARE MADE. EXTENSION TO PARTIAL BLOCKAGES ON MULTI-LANE FACILITIES IS DISCUSSED. THIS PAPER WAS ORIGINALLY PRESENTED AT THE HIGHWAY RESEARCH BOARD'S 52ND ANNUAL MEETING IN THE COMMITTEE SESSION ON TRAFFIC FLOW THEORY AND CHARACTERISTICS IN JANUARY 1973.
