DETERMINATION OF THE LANAL DISTRIBUTION OF TRUCK TRAFFIC ON FREEWAY FACILITIES

A STUDY WAS MADE OF VARIOUS TRAFFIC AND GEOMETRIC FACTORS WHICH COULD INFLUENCE THE LANAL DISTRIBUTION OF TRUCKS ON FREEWAY FACILITIES IN AN EFFORT TO DETERMINE A STATISTICALLY VALID METHOD OF PREDICTING LANE DISTRIBUTION FACTORS FOR USE IN STRUCTURAL PAVEMENT DESIGN. AN EXPERIMENTAL DESIGN WAS SET UP AND FOLLOWED DURING THE DATA COLLECTION PHASE WHICH INVOLVED NUMEROUS VEHICLE CLASSIFICATION COUNTS BY LANE ON FOUR AND SIX LANE URBAN AND FOUR LANE RURAL FREEWAYS. STATISTICAL TECHNIQUES INVOLVING ANALYSIS OF VARIANCE AND REGRESSION ANALYSIS WERE EMPLOYED TO EVALUATE THE DATA. ANALYSES INDICATED THAT TRAFFIC VOLUME WAS THE MOST SIGNIFICANT FACTOR AFFECTING TRUCK LANAL DISTRIBUTION ON FOUR LANE URBAN AND FOUR LANE RURAL FREEWAYS AND BOTH TRAFFIC VOLUME AND PERCENT TRUCKS WERE SIGNIFICANT ON SIX LANE URBAN FREEWAYS. EQUATIONS INVOLVING THESE FACTORS WERE DEVELOPED FOR PREDICTING LANE DISTRIBUTION FACTORS. /AUTHOR/
