MINI-COMPUTERS AND TRAFFIC CONTROL

THE FEASIBILITY OF THE APPLICATION OF COMPUTERS TO INDIVIDUAL TRAFFIC CONTROL WAS STUDIED. VARIOUS TRAFFIC CONTROLLER CONFIGURATIONS WERE SIMULATED BY COMPUTER PROGRAM WITH A SMALL MINI-COMPUTER. THE VERSATILITY OF THE VARIABLE LOGIC HARDWARE OF THE COMPUTER WAS DEMONSTRATED IN THE LABORATORY. A SUCCESSFUL FIELD INSTALLATION WAS MADE OF A MINI-COMPUTER TO REPLACE A STANDARD CONTROLLER CONFIGURATION. THE ADVANTAGES OF THE USE OF VARIABLE LOGIC COMPUTER AS A TRAFFIC CONTROLLER INCLUDES THE EASE OF MODIFICATION OF TRAFFIC CONTROL LOGIC AND THE ELIMINATION OF "FIXED" HARDWARE LOGIC CONSTRAINTS IMPOSED BY CURRENTLY USED CONVENTIONAL CONTROLLERS. THE APPLICATION OF MINI-COMPUTERS TO TRAFFIC CONTROL IS FEASIBLE AND VERY DESIRABLE. COST ANALYSIS INDICATES THAT A COMPUTER CONTROLLER WOULD BE COMPARABLE IN COST TO THE CURRENT, MUCH LESS VERSATILE. FIXED LOGIC CONTROLLER SYSTEMS USED IN MANY INSTALLATIONS. /AUTHOR/
