CONTROL CONSIDERATIONS AND SMOOTH FLOW IN VEHICULAR TRAFFIC NETS
THE REPORT PRESENTS SOME ANALYSIS, CONSTRAINTS, AND PROBLEM AREAS IN THE FORMAL STRUCTURE OF CONTROL (AND OF SOME PARTICULAR CONTROLLERS) ON THE SIGNALIZATION- ASSIGNMENT LEVEL OF A MULTILEVEL MACROSCOPIC CONTROLLER. THE OVERALL STRUCTURE AND PHILOSOPHY OF THE MULTILEVEL CONTROLLER ITSELF IS NOT PRESENTED, NOR ARE THE COMPUTER ASPECTS CONSIDERED EXPLICITYLY, THE DIGITAL COMPUTER BEING CONSIDERED ONLY AS A CONTROL DEVICE FOR PRESENT PURPOSES. A "SMOOTH-FLOW" CONTROL PHILOSOPHY IS PRESENTED, AND SOME CONSEQUENT CONTROLLERS FOR ARTERIALS AND FOR NETWORKS ARE DEMONSTRATED. SOME FORMAL CONSTRAINTS AND DIFFICULTIES IN STRUCTURING THE CONTROL PROBLEM ARE TREATED; THESE INCLUDE CYCLE LENGTH DEFINITION, PREDICTOR REQUIREMENTS, AND THE PROBLEM OF, AND BOUNDS ON, THE CLOSURE INTEGERS. ATTENDANT PROBLEMS IN ESTIMATION, COMPUTATION, AND STABILITY ARE ILLUSTRATED. AN ARTERIAL CONTROLLER IS DEVELOPED IN DETAIL; NETWORK CASES ARE DISCUSSED. /AUTHOR/
