Title: COMPARISON OF THREE PARAMETERS OF NONRESIDENTIAL TRIP GENERATION
Abstract: THIS PAPER ATTEMPTS TO ANSWER THE QUESTION, WHAT IS THE BEST TYPE OF LAND-USE MEASUREMENT FROM WHICH TO ESTIMATE TRIPS{ THIS QUESTION IS IMPORTANT NOT ONLY FOR TRIP ESTIMATION, BUT ALSO BECAUSE IT DICTATES WHAT TYPE OF LAND- USE SURVEYS A TRANSPORTATION STUDY MUST CONDUCT, AND THESE ARE VERY EXPENSIVE. THE ESTIMATING CAPABILITIES OF THE THREE MOST COMMON MEASURES OF LAND USE-LAND AREA, FLOOR AREA, AND EMPLOYMENT-ARE COMPARED. USING DATA COLLECTED BY THE CHICAGO AREA TRANSPORTATION STUDY, TRIP RATES BASED ON THESE THREE MEASURES ARE EXAMINED FOR FIVE NONRESIDENTIAL LAND-USE CATEGORIES USING CORRELATION AND REGRESSION ANALYSIS. THE RESULTING COEFFICIENTS AND EQUATIONS ARE GIVEN. THE FINDINGS INDICATE THAT NO ONE OF THESE MEASURES IS BEST FOR ALL LAND- USE CATEGORIES. FLOOR AREA SEEMS BEST FOR COMMERCIAL, EMPLOYMENT FOR MANUFACTURING, AND LAND AREA FOR PUBLIC BUILDINGS, PUBLIC OPEN SPACE, AND TRANSPORTATION. CONTRARY TO EXPECTATION, FLOOR AREA DOES NOT SEEM CONSISTENTLY BETTER THAN LAND AREA. FURTHERMORE, FLOOR AREA TRIP RATES ARE NOT UNIFORM THROUGHOUT A METROPOLITAN AREA, BUT INCREASE AS THE DENSITY DECREASES. THE RESULTS SUGGEST THAT FURTHER RESEARCH ON TRIP GENERATION IS NEEDED, UNDERSTANDING OF THE SUBJECT IS STILL QUITE FRAGMETARY. FIVE SPECIFIC APPROACHES FOR DEEPER INVESTIGATION ARE RECOMMENDED. IN ADDITION, MORE COMPREHENSIVE SURVEYS OF THE THREE PARAMETERS ARE STILL REQUIRED FOR RESEARCH PURPOSES. /AUTHOR/
