AN ANALYSIS OF SPEED CHANGES FOR LARGE TRANSPORT TRUCKS
RESEARCH WAS CONDUCTED TO DEVELOP A MEANS OF CALCULATING THE SPEED AND ACCELERATION CHARACTERISTICS OF LARGE TRANSPORT TRUCKS ON VARIOUS GRADES AND ACCELERATION LANES. BY MEANS OF A FORCE AND MOMENTUM BALANCE, A METHOD WAS DEVISED FOR CALCULATING THE SPEED VS DISTANCE HISTORY OF LARGE TRUCKS TRAVERSING VARIOUS TYPES OF VERTICAL HIGHWAY CURVES AT WIDE-OPEN THROTTLE. THE EQUATIONS THAT RESULTED WERE SOLVED WITH THE AID OF ELECTRONIC COMPUTING MACHINES OVER VARIOUS RANGES OF VALUES OF VEHICLE AND HIGHWAY PROPERTIES. RESULTS OF THE CALCULATIONS ARE PRESENTED AS CHARTS RELATING VEHICLE SPEED TO DISTANCE ALONG THE VERTICAL HIGHWAY CURVES. A COMPARISON OF CALCULATED AND EXPERIMENTAL VALUES SHOWED SATISFACTORY AGREEMENT. VARIOUS POSSIBLE METHODS OF UTILIZING THE CHARTS FOR HIGHWAY DESIGN OR VEHICLE SELECTION PURPOSES ARE DISCUSSED.
