Abstract	THE DYNAMIC CONTROL OF A CASCADE OF HIGH-SPEED VEHICLES USING AN ON-LINE DIGITAL COMPUTER IS CONSIDERED. THE VEHICLES ARE CONTROLLED OPTIMUMLY IN TERMS OF SPEED, SPACING AND ACCELERATION PERFORMANCE. FOR THE PURPOSE OF THE TRAFFIC MODEL, ALL THE DIFFERENT SYSTEMS REDUCE, ESENTIALLY, TO A STRING OF CASCADED VEHICLES WHICH ARE DRIVEN ELECTRICALLY (OR PNEUMATICALLY) AND CONTROLLED ELECTRONICALLY AS REGARDS VEHICLE SPEEDS, SPACINGS, ACCELERATIONS AND DESTINATIONS. THE RESULTS OBTAINED ARE BASED ON THE LINEARITY OF THE SYSTEM. THE RESULTS INDICATE THAT A CASCADE OF VEHICLES IN A HIGH-SPEED TRANSPORT SYSTEM MAY BE REGULATED OPTIMUMLY WITH REGARD TO SPACING AND VELOCITY BY MEANS OF AN ON-LINE DIGITAL COMPUTER. FOR THE HIGH-SPEED TRANSPORT MODEL CONSIDERED THE CONTROL ALGORITHM CONVERGES RAPIDLY UNDER DIGITAL COMPUTATION USING TRANSITION AND DRIVING MATRICIES WHICH CAN BE FORMED IN A PARTICULAR MANNER FROM THE BASIC SYSTEM DATA. THE APPROACH CAN BE SEEN TO PROVIDE A COMPUTATIONAL FEASIBLE ALGORITHM EVEN FOR MODERATELY HIGH-ORDER SYSTEMS COMPRISING 12 VEHICLES.
