Title: AUTOMOBILE OCCUPANCY PROJECTIONS USING A MODAL-SPLIT MODEL
Accession Number: 00227952
Record Type: Component
Abstract: THE USE OF A DIVERSION-CURVE, MODAL-SPLIT MODEL IS PROPOSED AS A METHOD OF CONVERTING PERSON TRIPS ON A HIGHWAY NETWORK TO VEHICLE TRIPS. THE MODEL IS PROGRAMMED FOR THE CDC 3600 COMPUTER. INVESTIGATION WAS DONE TO DETERMINE SIGNIFICANT VARIABLES FOR PREDICTING VEHICLE USAGE. MEDIAN FAMILY INCOME AT THE PRODUCTION END OF THE TRIP, ORIENTATION OF THE TRIP TO THE CENTRAL BUSINESS DISTRICT OR TO LOCATIONS OTHER THAN THE CENTRAL BUSINESS DISTRICT, TRAVEL TIME, AND TRIP PURPOSE WERE USED AS VARIABLES. CURVES RELATING THE PERCENTAGE OF HIGHWAY PERSON TRIPS MADE BY DRIVERS TO THESE VARIABLES WERE DEVELOPED AND THE MODEL WAS TESTED WITH BASE-YEAR DATA. THE TOTAL ERROR IN PREDICTED VEHICLE TRIPS WAS LESS THAN 0.5 PERCENT INDICATING THAT THIS TYPE OF MODEL IS WELL SUITED TO PREDICTION OF VEHICLE USAGE. PROJECTIONS TO A FUTURE YEAR INDICATED THAT SIGNIFICANT DECREASES IN AUTOMOBILE OCCUPANCY WILL OCCUR. /AUTHOR/
