MEASURES OF EFFECTIVENESS FOR URBAN TRAFFIC CONTROL SYSTEMS

ANALYSES ARE DESCRIBED THAT ARE PART OF A CONTRACT TO DEVELOP A SECOND-GENERATION SURVEILLANCE METHODOLOGY, PROVIDING MORE DETAILED AND ACCURATE INFORMATION THAN THE SYSTEMS INSTALLED IN TORONTO AND WICHITA FALLS, FOR USE IN A COMPUTERIZED TRAFFIC CONTROL SYSTEM. THE ANALYSES HAVE TO DO WITH DEFINITION OF OBJECTIVES AND OF MEASURES OF SYSTEM EFFECTIVENESS (MOE). A LIST OF MOE EVALUATION CRITERIA WAS COMPILED AND USED TO REDUCE 40 CANDIDATE MOE TO THREE RECOMMENDED ONES: TRAVEL TIME, SERVICE RATE (ALSO CALLED TOTAL TRAVEL) COMPUTED AS THE PRODUCT OF VOLUME AND LINK LENGTH, AND THE RATIO OF EFFECTIVE TO SPOT KINETIC ENERGIES. ENERGY RATIO WAS NOT ENCOUNTERED IN THE LITERATURE REVIEWED BUT WAS DEVELOPED DURING THE STUDY AS A READILY OBTAINABLE MEASURE FOR FLOW SMOOTHENESS. THE TRAFFIC PARAMETERS REQUIRED TO COMPUTE THESE MOE ARE SPECIFIED. PRESENTATION OF DATA AND THEIR USE FOR CONTROL ARE ALSO CONSIDERED. /AUTHOR/
