Evaluating Land Use Methods for Altering Travel Behavior. Final Report for Task1b: Transit Patronage as a Product of Land Use Potential and Connectivity: The Sacramento Case

摘要

This study uses Sacramento Regional Transit data to determine conditions underwhich transit can attract traffic in suburbs. It specifies a direct demand model in which trip productions and attractions are a function of zonal characteristics and transit connectivity from a given zone to places where transit user want to go in the region. The model derivation identifies a new concept, trip production and attraction potential, which is independent of transportation connectivity but which is a function of zonal socio-economic and design characteristics. The study estimates production and attraction potentials and connectivity for 70 Sacramento County census tracts. With this information, it identifies suburban tracts where the transit system succeeds in taping potential traffic, and it identifies qualities of the transit system associated with such success. It also shows where the transit system fails to tap potential.
