THE GLASGOW EXPERIMENT: IMPLEMENTATION AND ASSESSMENT

THE PLANNING AND CONDUCT ARE DISCUSSED OF THE GLASGOW EXPERIMENT IN CENTRAL CONTROL OF TRAFFIC SIGNALS. THE ORGANIZATION OF THE VARIOUS COMPUTER PROGRAMS, WHICH WILL, AMONGST OTHER TASKS, CONTINUALLY TAKE IN DATA ON CURRENT CONDITIONS, MAKE DECISIONS TO CHANGE SIGNALS, MONITOR THE OPERATION OF THE WHOLE SYSTEM, CHECK FOR FAULTY OPERATION, PRODUCE RECORDS AND PRINT MESSAGES IS DESCRIBED. A METHOD OF LINKING FIXED-TIME TRAFFIC SIGNALS TO MINIMIZE DELAY IS DESCRIBED AND THE IMPLICATIONS OF SOME OF ITS ASSUMPTIONS DISCUSSED. THE GENERAL PROBLEM OF ASSESSING THE EFFICIENCY OF EACH CONTROL SCHEME IS CONSIDERED. REASONS ARE PUT FORWARD FOR ASSESSING EFFICIENCY IN TERMS OF THE TOTAL VEHICLE-HOURS MEASURED OVER THE NETWORK. SOME OF THE PRACTICAL PROBLEMS INVOLVED IN ASSESSMENT ARE ALSO CONSIDERED. /AUTHOR/
