摘要

The procedures used by transportation planning agencies to forecast future travel demand and the split of demand among drive alone, ridesharing and public transit are quite complex. Over the past thirty years, a basic process has been developed that involves four major elements. 1. How many trips will be made. (Trip generation) 2. What destinations will be selected by people living in specific areas. (Trip distribution) 3. How will travel be divided between driving alone, ridesharing and public transit. (Mode choice) 4. How many vehicles or people will want to use specific roadways or transit services. (Assignment) Over time, as more research has been reported on personal travel behavior, new procedures were recommended. Advances in personal computer technology and reduced costs for computers has made it possible to implement many of the methods recommended by the research. As this has happened, the methodologies used to consider each of the questions have become more complex.
