DEVELOPMENT OF CRITERIA FOR EVALUATING TRAFFIC OPERATIONS

THE REPORT CONSISTS OF TWO VOLUMES OF WHICH THE SECOND VOLUME IS ESSENTIALLY AN APPENDIX REITERATING THE MATERIAL IN VOLUME I, WITH SOME ADDITIONAL TABLES, CHARTS AND ANNOTATED BIBLIOGRAPHIC REFERENCES. THE MAIN EMPHASIS IN THIS STUDY WAS ON RELATING EFFICIENCY CRITERIA TO A MEASURABLE TRAFFIC PARAMETER, IN THIS CASE VOLUME. CRITERIA IS DEFINED TO CONSIST OF DRIVER SATISFACTION FACTORS' TRAVEL TIME, DRIVER DISCOMFORT, DRIVING HAZARD /ACCIDENTS/ AND DIRECT VEHICLE RUNNING COST. FIELD DATA FROM SEVERAL CITIES IS USED INCLUDING GSR AND BASE CONDUCTANCE MEASUREMENTS FOR DRIVER DISCOMFORT FACTORS. VARIOUS STATISTICAL ANALYSIS TECHNIQUES ARE APPLIED TO PROVE THAT AN IDENTIFIABLE RELATIONSHIP EXISTS. OTHER VARIABLES SUCH AS SIGNAL DENSITY, CYCLE LENGTHS, ETC. ARE DISCUSSED AND EQUATIONS DEVELOPED FOR ESTIMATING A NET MEASURE OF CONGESTION TO EVALUATE THE OPERATION OF A STREET. THE REPORT CONCLUDES THAT SIGNIFICANT RELATIONSHIPS EXIST BETWEEN THE DRIVER SATISFACTION FACTORS AND VOLUME FOR BROAD CLASSES OF URBAN ARTERIALS AND THAT THESE RELATIONSHIPS ARE LINEAR. /BPR/
