SIMULATION OF TRAFFIC FLOW AS A BASIS FOR INTERCHANGE DESIGN

A SIMULATION PROGRAM HAS BEEN DEVELOPED FOR EVALUATION OF INTERCHANGE DESIGN AND SPACING. THE DESIGN CRITERIA ESTABLISHED BY THE GENERATED OUTPUT OF DISTANCES NEEDED FOR ACCOMPLISHING VEHICLE INTERCHANGE TO AND FROM THE THROUGH FREEWAY LANES ARE /1/ THE LENGTH OF AUXILIARY LANE BETWEEN LOOPS OF A CLOVERLEAF INTERCHANGE,/2/ THE MINIMUM DISTANCE NEEDED BETWEEN ENTRANCE AND EXIT RAMPS OF SUCCESSIVE INTERCHANGES WHERE THERE IS AN AUXILIARY LANE BETWEEN THE ENTRANCE AND EXIT RAMP AND 3/ THE LENGTH OF ACCELERATION LANE NEEDED TO PERMIT MERGING OF ENTRANCE RAMP VEHICLES. THE DESIGN NEEDS CAN BE GENERATED FOR VARIOUS TRAFFIC DEMANDS. /BPR/
