RELATIONSHIPS OF TRAFFIC AND FLOOR SPACE USE IN CENTRAL BUSINESS DISTRICT

IN 1960, HARPER AND EDWARDS DEVELOPED LINEAR REGRESSION MODELS FOR SEVEN CITIES RELATING TRAFFIC FLOW TO THE CENTRAL BUSINESS DISTRICT TO FLOOR SPACE USE. THIS IS AN EXTENSION IN WHICH MODELS ARE DEVELOPED FOR CITIES OVER A WIDE POPULATION RANGE AND FOR TRIPS MADE FOR DIFFERENT PURPOSES. SIGNIFICANT MODELS WERE DEVELOPED FOR TOTAL TRAFFIC AND FOR WORK, SHOPPING, AND BUSINESS TRIPS. SOCIAL AND RECREATION TRIPS TO THE CBD WERE NOT FOUND TO BE SIGNIFICANTLY RELATED TO FLOOR SPACE USE. THE RESEARCH SHOWED THAT TRAFFIC FLOW TO THE CBD IS MOST CLOSELY RELATED TO THE FOLLOWING CLASSIFICATIONS OF FLOOR SPACE USE' RETAIL SALES, SERVICE, OFFICE, AND PUBLIC. NO SIGNIFICANT RELATIONSHIPS WERE FOUND BETWEEN TRAFFIC AND MANUFACTURING, WHOLESALING, AND SEMI-PUBLIC FLOOR SPACE USE. BY USING COMMON FLOOR SPACE GROUPINGS OF RETAIL AND SERVICE-OFFICE, IT IS SHOWN THAT REGRESSION COEFFICIENTS FOR THESE VARIABLES ARE SIGNIFICANTLY RELATED TO CITY POPULATION. HOWEVER, IMPORTANT DIFFERENCES IN THE MODELS WERE NOTED FOR CITIES OF SIMILAR SIZE, SUGGESTING THAT MORE RESEARCH IS NEEDED TO IDENTIFY AND QUANTIFY OTHER SOURCES OF VARIATION IN THE REGRESSION COEFFICIENTS. IT IS ALSO SHOWN THAT REGRESSION COEFFICIENTS IN LINEAR MODELS RELATING CBD TRAFFIC FLOW AND FLOOR SPACE USE ARE INFLUENCED BY THE SIZE AND NUMBER OF ORIGIN-DESTINATION ZONES. THE USE OF SMALLER ZONES TENDS TO PRODUCE BETTER STRATIFICATION OF THE DATA AND RESULTS IN MORE RELIABLE MODELS. /AUTHOR/
