AN AUTOMATIC SYSTEM FOR LONGITUDINAL CONTROL OF INDIVIDUAL VEHICLES
A PROPOSED LONGITUDINAL AUTOMATIC SYSTEM FOR CONTROLLING AN INDIVIDUAL VEHICLE IN A TRAFFIC STREAM IN RESPONSE TO THE IMMEDIATELY PRECEDING VEHICLE IS DESCRIBED. THE AUTOMATIC CONTROL OF INDIVIDUAL HIGHWAY VEHICLES SHOULD CONSIDERABLY IMPROVE HIGH-DENSITY TRAFFIC FLOW. A SHORT DESCRIPTION IS INCLUDED OF THE TRAFFIC SITUATION VARIABLES, THE REQUIREMENTS ON THE SYSTEM, A DESCRIPTION OF THE SYSTEM ITSELF, AND A DISCUSSION OF THE PERFORMANCE OF THE SYSTEM. LINEAR AND NONLINEAR MODES OF CONTROL WERE COMBINED. THE SYSTEM WAS ANALYZED IN THE CAR-FOLLOWING SITUATION IN SINGLE LANE TRAFFIC WITH UP TO THREE CARS IN A LINE. MORE EXTENSIVE EVALUATION FOR MANY CARS IN A PLATOON AND FOR COMPARISON WITH THE PRESENT MANUAL SYSTEM HAS NOT BEEN COMPLETED. HOWEVER, THE RESULTS OF PRESENT ANALYSIS INDICATE THAT GOOD PERFORMANCE CAN BE EXPECTED.
