VEHICLE TRAJETORIES AFTER INTERSECTION COLLISION IMPACT

THE POSTCOLLISION MOTION STARTS IMMEDIATELY UPON COMPLETION OF A COLLISION IMPACT WHERE THE VEHICLES OBTAIN NEW SETS OF VELOCITIES THROUGH AN EXCHANGE OF MOMENTUM. SIMILITUDE WITH MODEL STUDY AND FULLSCALE AUTOMOBILE EXPERIMENTS INDICATE THAT THE POST-COLLISION TRAJECTORY IS ESSENTIALLY A PLANE MOTION, GOVERNED BY INERTIA AND TIRE FRICTION. TRAJECTORIES DEPEND ON MANY PARAMETERS (SUCH AS TIRE FRICTION COEFFICIENT, FRONT WHEEL STEERING ANGLE, VEHICLE GEOMETICS, AND WHETHER WHEELS ARE LOCKED OR FREE TO ROTATE) BUT NOT ON THE VEHICLE WEIGHT. THEORETICAL COMPUTATION OF TRAJECTORIES ARE COMPARED WITH EXPERIMENTS. /AUTHOR/
