LATERAL DISTRIBUTION OF TRAFFIC ON A FOUR LANE AND SIX-LANE SECTION OF 1-75 SOUTH OF COVINGTOM

THE PURPOSE IS TO PROVIDE THE BASIC INFORMATION NECESSARY FOR ESTIMATING DESIGN EQUIVALENT AXLE LOADS (EAL) FOR EACH LANE FOR MULTILANE FACILITIES. LANE DISTRIBUTION DATA WAS ANALYZED BY (1) DEVELOPING PLOTS OF LANE USAGE VERSUS TRAFFIC VOLUME. (2) USING MULTIPLE REGRESSION TECHNIQUES FOR SIMULATING GRAPHIC RELATIONSHIPS, AND (3) COMPUTING THE CORRESPONDING STATISTICAL ERRORS OF THE ABOVE RELATIONSHIPS. LANE DISTRIBUTION DATA IS USED IN ESTABLISHING TRAFFIC OPERATIONAL CHARACTERISTICS. THE PRESENT METHOD-IN KENTUCKY- FOR PREDICTING DESIGN EAL'S ASSUMES THAT ALL EAL'S ARE ACCUMULATED IN THE OUTSIDE LANE. SINCE COMMERCIAL VEHICLES PROVIDE THE MAJOR EAL CONTRIBUTION, THE PRIMARY INTEREST FOR FLEXIBLE PAVEMENT DESIGN FOR MULTILANE HIGHWAYS CONCERN THE LATERAL DISTRIBUTION OF COMMERCIAL VEHICLES.
