TRIP GENERATION: A CRITICAL APPRAISAL

A CRITICAL EVALUATION IS PRESENTED OF THE CONSEQUENCE ASSOCIATED WITH ALTERNATE APPROACHES TO THE TRIP-GENERATION PROCESS. THE FIRST PART OF THE RESEARCH EXAMINES THE PERFORMANCE OF RELATIONSHIPS BASED ON AGGREGATE TOTALS (SUCH AS TRIPS PER ZONE) AS OPPOSED TO THE USE OF AGGREGATE RATES (SUCH AS TRIPS PER HOUSEHOLD PER ZONE). THE SECOND PART CONCENTRATES ON THE IMPLICATIONS OF USING DISAGGREGATED DATA (DATA NOT COMBINED AND AVERAGED ACCORDING TO PREDEFINED AREAL UNITS). BOTH ANALYSES WERE PERFORMED ON THE SAME DATA BASE AND EMPLOYED THE SAME SET OF VARIABLES. THE ANALYSES TOOL OF MULTIPLE LINEAR REGRESSION WAS APPLIED TO BOTH PHASES OF THE RESEARCH UTLIZING TWO INDEPENDENT SETS OF DATA, ONE FOR CALIBRATING OR FITTING THE DATA AND THE OTHER FOR TESTING THE RESULTS. THE RESULTS INDICATE THAT IN STATISTICAL TESTS TO MEASURE AND EVALUATE ON A COMMON BASIS THE DISAGGREGATE TRIP-GENERATION PROCEDURES THE AGGREGATE PROCEDURES PRODUCED SLIGHTLY BETTER RESULTS AND ARE THE RECOMMENDED PROCEDURE. /AUTHOR/
