A DIGITAL SIMULATION PROGRAM OF A SECTION OF FREEWAY WITH ENTRANCE AND EXIT RAMPS

A COMPUTER PROGRAM DEVELOPED FOR THE SIMULATION OF A SECTION OF FREEWAY, INCLUDING SEVERAL EXIT AND ENTRANCE RAMPS IS DESCRIBED. THE PROGRAM ALLOWS FOR THE SIMULATION OF THE TRAFFIC OPERATION UNDER DIFFERENT MODES OF ENTRANCE RAMP CONTROL: FIXED-RATE METERING, DEMAND-CAPACITY METERING, GAP- ACCEPTANCE CONTROL AND, OF COURSE, NO CONTROL. THE COMPUTER LOGIC AND SIMULATION TECHNIQUE ARE DISCUSSED IN DETAIL. LIMITED OUTPUT OF THE PROGRAM IS PRESENTED AS EVIDENCE OF THE FEASIBILITY AND REALISM OF THE SIMULATION MODEL. /AUTHOR/
