COMMUNICATIONS AND TRAFFIC MANAGEMENT
THIS PAPER ADVOCATES THE TRAFFIC MANAGEMENT APPROACH TO DEVELOPING A RATIONAL PLAN FOR CONGESTION CONTROL. EMPHASIS IS PLACED ON THE COMMUNICATION NEEDS IN TRAFFIC MANAGEMENT. THE LOS ANGELES SURVEILLANCE AND CONTROL SYSTEM IS CITED AS AN EXAMPLE OF THE TREND IN DATA ACQUISITION AND CONTROL SYSTEMS. THIS TYPE OF SYSTEM PROVIDES ESSENTIAL INFORMATION TO THE MANAGEMENT PROCESS. THE EXCELLENT COORDINATION AND COMMUNICATION BETWEEN INVOLVED OPERATING AGENCIES IS PARTICULARLY NOTEWORTHY IN THE LOS ANGELES SYSTEM. THE LARGE EXPENDITURES FOR COMMUNICATIONS ENCOURAGE THE USE OF COST-SAVING MULTIPLEXING TECHNIQUES. THE MULTIPLEXING TECHNIQUES DESCRIBED IN THE PAPER INCLUDE FREQUENCY AND TIME DIVISION MULTIPLEXING. COMMENTS ARE INCLUDED CONCERNING THE ERROR DETECTION AND CORRECTION CODES USED TO PRESERVE THE INTEGRITY OF THE COMMUNICATION LINK. ALL KINDS OF COMMUNICATION TECHNOLOGY ARE NOW AT HAND, THE MISSING INGREDIENT IS THE PERSON TO HARNESS THIS WEALTH IN A SOLUTION TO TRAFFIC PROBLEMS. THE COMPETITION TO MANAGE THE SYSTEM WILL BE INTENSIVE, THE TRAFFIC ENGINEER WILL HAVE TO FIGHT IF HE WANTS TO PLAY SUCH A KEY ROLE IN THE TRANSPORTATION SYSTEM.
