• Abstract:
  THE STUDY INVESTIGATES THE APPLICATION OF SIMULATION ALONG WITH FIELD OBSERVATIONS FOR ESTIMATION OF EXCLUSIVE LEFT-TURN SATURATION FLOW RATE AND CAPACITY. THE ENTIRE RESEARCH HAS COVERED THE FOLLOWING PRINCIPAL SUBJECTS: (1) A SATURATION FLOW MODEL FOR PROTECTED PHASE THAT ALLOWS ENGINEERS TO INCORPORATE LOCAL-SPECIFIC DRIVING BEHAVIOR IN THE ANALYSIS; (2) A PERMITTED SATURATION FLOW MODEL THAT ACCOUNTS FOR THE IMPACT OF DRIVING BEHAVIOR AND TRAFFIC CONDITIONS AT BOTH THE TARGET AND THE OPPOSING UPSTREAM INTERSECTIONS ON THE PERMITTED SATURATION FLOW RATE; (3) A QUEUE LENGTH MODEL FOR ESTIMATION OF THE RESULTING QUEUE LENGTH UNDER VARIOUS PHASE SCHEMES; AND (4) A HYBRID BAY LENGTH IMPACT MODEL THAT PROVIDES ENGINEERS A CONVENIENT TOOL TO ASSESS THE IMPACT OF VARIOUS BAY LENGTHS ON THE LEFT-TURN CAPACITY AT BOTH ISOLATED AND COORDINATED INTERSECTIONS. THIS REPORT ALSO DESCRIBES THE PROCEDURES FOR DIRECT ESTIMATION OF INTERSECTION CAPACITY WITH SIMULATION, INCLUDING A SET OF RIGOROUS STATISTICAL TESTS FOR SIMULATION PARAMETER CALIBRATION FROM FIELD DATA.
