MULTIPLE REAR-END COLLISIONS IN FREEWAY TRAFFIC, THEIR CAUSES AND THEIR AVOIDANCE

THE SENSITIVITY FACTOR OF STIMULUS-RESPONSE CAR FOLLOWING EQUATIONS WAS COMPUTED. VEHICLES OF A PLATOON ARE INVESTIGATED AS THEY APPROACH, PROCEED THROUGH, AND LEAVE BEHIND A KINEMATIC DISTURBANCE, AND AN INHERENT LOCAL AND ASYMPTOTIC INSTABILITY IS DISCOVERED. AERIAL SURVEY DATA ARE USED IN A NUMERICAL EXAMPLE TO DEMONSTRATE HOW MULTIPLE REAR-END COLLISIONS CAN BE TRIGGERED BY ONE VEHICLE. A DRIVER AID SYSTEM COULD IMPROVE STABILITY, ALTHOUGH THE FINAL ANSWER APPEARS TO LIE IN AUTOMATED OR SEMI-AUTOMATED LONGITUDINAL CONTROL SYSTEMS /HSL/
