A COMPARISON OF SOME BUNCHING MODELS FOR RURAL TRAFFIC FLOW

ON TWO-LANE TWO-WAY ROADS OVERTAKING OPPORTUNITIES ARE OFTEN LIMITED BY TRAFFIC AND HIGHWAY FACTORS SO THAT VEHICLES MAY BE FORCED TO QUEUE BEHIND SLOWER VEHICLES BEFORE OVERTAKING CAN TAKE PLACE. TO EXPLAIN THIS CLUSTERING OR BUNCHING OF TRAFFIC SEVERAL BUNCHING MODELS HAVE BEEN PROPOSED. ONE SUCH MODEL WHICH HAS BEEN USED IS THE BOREL-TANNER DISTRIBUTION OF BUNCH SIZES. THE PAPER EXAMINES THIS MODEL, AND OTHERS, AND COMPARES THEM USING BOTH EXPERIMENTAL AND SIMULATED BUNCH SIZE DATA. FROM THE COMPARISON IT IS SUGGESTED THAT A MORE GENERAL MODEL THAN THE BOREL-TANNER MODEL IS THE TWO- PARAMETER MILLER DISTRIBUTION OF BUNCH SIZES WHICH CAN BE FITTED TO A WIDE RANGE OF TRAFFIC CONDITIONS. /AUTHOR/
