GRAVITY MODEL THEORY APPLIED TO A SMALL CITY USING A SMALL SAMPLE OF ORIGIN-DESTINATION DATA

THE RESEARCH WAS CONCERNED WITH THE USE OF THE GRAVITY MODEL IN A SMALL CITY /HUTCHINSON, KANSAS, 37,000 POPULATION/ AND WAS CONDUCTED TO STUDY THE FEASIBILITY OF USING A SMALL CLUSTERED SAMPLE OF O-D INTERVIEWS TO ESTIMATE THE GRAVITY MODEL PARAMETERS, TRIP PRODUCTION, TRIP ATTRACTION, AND TRAVEL TIME FACTORS. THE MODEL WAS CALIBRATED USING THE ESTIMATIONS OF TRIP PRODUCTIONS AND ATTRACTIONS WAS COMPARED TO THE TRIP DISTRIBUTION OBTAINED FROM A COMPLETE O-D SURVEY. A GRAVITY MODEL WAS CALIBRATED USING O-D PRODUCTIONS AND ATTRACTIONS AND THE RESULTING DISTRIBUTION WAS ALSO USED IN THE COMPARISON OF RESULTS. THE INFORMATION WAS OBTAINED FROM INTERVIEWS AND WAS LIMITED TO CONSIDERATION OF AUTO-DRIVER TRIPS WHICH WERE INTERNAL IN NATURE. THREE TRIP PURPOSES - HOME-WORK, HOME-OTHER, AND NON-HOME BASED- WERE STUDIED IN DETAIL. THE METHOD OF USING THE CLUSTERED SAMPLE /REDUCED SAMPLE SIZE IN THE ZONES/ ENABLES ADEQUATE ESTIMATION OF EXISTING ZONAL TRIP PRODUCTIONS. THE TRAVEL TIME FACTORS WERE SATISFACTORILY ESTIMATED USING DATA FROM THE CLUSTERED SAMPLE STUDY. ANALYSIS OF THE RESULTS OF THE GRAVITY MODEL DISTRIBUTION, USING PRODUCTIONS, ATTRACTIONS, AND TRAVEL TIME FACTORS BASED ON THE CLUSTERED SAMPLE, INDICATES THAT THE EXISTING TRIP DISTRIBUTION AS MEASURED BY THE COMPLETE O-D SURVEY DATA CAN BE ADEQUATELY REPRODUCED.
