A THEORETICAL ANALYSIS OF CONGESTION IN A TWO-LANE FREEWAY

A MODEL IS SUGGESTED IN WHICH IT IS ASSUMED THAT MOST VEHICLES TRAVEL AT APPROXIMATELY IDENTICAL, MORE OR LESS CONSTANT, SPEEDS AND THAT ALL OF THE CONGESTION IS CAUSED BY A SMALL PROPORTION OF SLOWER VEHICLES. INTERACTIONS BETWEEN THE BUNCHES QUEUEING BEHIND SLOWER VEHICLES ARE IGNORED. TWO OVERTAKING RULES ARE SUGGESTED, AND IS SHOWN THAT WITH VARIOUS OTHER ASSUMPTIONS AN EXACT ANALYSIS IS POSSIBLE. THIS ANALYSIS IS DIRECTED TOWARDS OBTAINING AN EXPRESSION FOR THE RATE OF DELAY GENERATED BY A PARTICULAR SLOWER VEHICLE AND, ALSO, THE DELAY SUFFERED BY A "NORMAL VEHICLE" IN TRAVELLING THROUGH A GIVEN LENGTH OF FREEWAY. METHODS OF ESTIMATING UNKNOWN PARAMETERS WITH A VIEW TOWARDS VALIDATION STUDIES ARE ALSO GIVEN. /AUTHOR/
