OPERATIONAL EFFECTS OF AUTO-UTILITY TRAILER COMBINATIONS ON RURAL HIGHWAYS IN KENTUCKY
AN ANALYSIS OF ACCIDENT RECORDS INDICATED THAT AUTO- UTILITY TRAILER (A-UT) COMBINATIONS ARE INVOLVED IN A DISPROPORTIONATELY HIGH NUMBER OF TRAFFIC MISHAPS. LOCATIONS WHICH HAVE A HISTORY OF ACCIDENTS INVOLVING A-UT VEHICLES INDICATED THAT DIFFERENTIAL CROSSWINDS AND UNANTICIPATED DRIVING MANEUVERS CONTRIBUTE TO DRIVER LOSS OF CONTROL. A-UT COMBINATIONS CONTRIBUTED TO THE FATIGUE LOSS IN PAVEMENT LIFE APPROXIMATELY 50 PERCENT AS MUCH AS SINGLE-UNIT, TWO-AXLE, SIX-TIRE TRUCKS (PER VEHICLE). IN GENERAL, THIS VEHICLE TYPE CONSTITUTED APPROXIMATELY THREE PERCENT OF THE TOTAL TRAFFIC STREAM. ANALYSIS OF SPEED DISTRIBUTIONS INDICATED AN EQUIVALENCY FACTOR FOR A-UT COMBINATIONS EQUAL TO THAT FOR TRUCKS FOR SIMILAR ROADWAY TYPES AND TOPOGRAPHICAL CONDITIONS. /AUTHOR/
