Title: RAMP CAPACITY AND SERVICE VOLUME AS RELATED TO FREEWAY CONTROL
Accession Number: 00225539
Record Type: Component
Abstract: THE PROBLEM OF ESTABLISHING A POLICY FOR FREEWAY CONTROL CAN BE STRUCTURED INTO AN ORDERED SET OF CONTROL PROBLEMS WITHIN A HIERARCHY OF LEVELS OF CONTROL. AT EACH LEVEL ASSOCIATED WITH THE HIERARCHY OF THE PROBLEM STRUCTURE, AN INTERRELATION EXISTS AMONG FREEWAY-CAPACITY, FREEWAY-DEMAND, RAMP-CAPACITY, RAMP-DEMAND, OUTSIDE-FREEWAY-LANE-FLOW, AND RAMP-MERGING CHARACTERISTICS AND MERGING-CONTROL SYSTEM OPERATION. THE EXTENT TO WHICH AN OPTIMUM CONTROL POLICY CAN BE ESTABLISHED AT EACH LEVEL OF CONTROL IS DIRECTLY RELATED TO THE EXTENT TO WHICH THE PERTINENT TRAFFIC AND CONTROL SYSTEM VARIABLES CAN BE INTERRELATED. IN THIS REPORT, RAMP CAPACITY AND SERVICE VOLUME ARE DEFINED IN TERMS OF ENTRANCE-RAMP GEOMETRY AND GAP-ACCEPTANCE AND MERGING- CONTROLLER-OPERATIONAL CHARACTERISTICS. SUBSEQUENTLY, AN OPTIMAL CONTROL POLICY IS ESTABLISHED FOR AN ISOLATED ENTRANCE RAMP AND THE INTEGRATED TOTAL FREEWAY CONTROL POLICY MODELED. /AUTHOR/
