DEVELOPMENT AND APPLICATION OF DIRECT TRAFFIC ESTIMATION METHOD

THE PAPER DESCRIBES THE FOLLOWING MAJOR PROBLEMS ENCOUNTERED IN THE PROCESS OF PROGRAMMING AND TESTING THE DIRECT TRAFFIC ESTIMATION METHOD: HOW TO ESTIMATE CONTRIBUTIONS TO VOLUMES OF INDIVIDUAL ZONES, HOW TO DEAL WITH SYMMETRIC NETWORKS, HOW DOMAIN OVERLAP OCCURS AND CAN BE IDENTIFIED AND HOW TO IMPROVE RESULTS BY SMOOTHING THE BOUNDARIES BETWEEN MAIN AND PRIME DOMAINS. THE MAJOR CONCLUSIONS OF THE FIRST-STAGE TESTING OF THE MODEL ARE AS FOLLOWS: (A) THE MODEL PRODUCES RELIABLE EXPRESSWAY VOLUME ESTIMATES THAT MAY BE USED FOR PLANNING AND ANALYSIS; (B) CURRENTLY, IT IS NOT RECOMMENDED THAT THE MODEL BE USED FOR ESTIMATING ARTERIAL VOLUMES, AND, IN CASE SUCH A USE IS MADE, THE RANGE OF POSSIBLE ERRORS SHOULD BE KEPT IN MIND; AND (C) APPLICATION OF THE MODEL GIVES AN EXCELLENT METHOD FOR DESCRIBING THE PROBABLE SOURCES OF TRAFFIC ON A GIVEN LINK AND THE FUNCTION OF THE LINK IN SERVING THE TRAVEL DEMAND AS A PART OF THE NETWORK. VISUAL REPRESENTATION OF THE RESULTS USING THE AVAILABLE AUXILIARY PROGRAMS IS OF SPECIAL HELP. /AUTHOR/
