PROCEDURE FOR ESTIMATING FREEWAY TRIP TABLES
Nancy L. Nihan · Transportation Research Record Journal of the Transportation Research Board · 1982
A method for estimating freeway trip tables with volume data by using a gravity-based model is presented. The 1969 San Francisco Bay Area origin-destination survey is used to test the estimates. The results of using the gravity-based model are compared with the estimates obtained by using the SYNODM approach developed at the University of California, Berkeley. The gravity-based approach achieves a closer fit to the actual trip tables than does the current version of SYNODM. (Author)
