Abstract

This study examines the effects of overlapping walking service areas, residential density, and frequency of bus service on the demand for bus transit. This requires controlling for variation in potential transit demand as measured by the number of dwelling units and their location and the effect of income. The model of passenger boardings is a function of the potential transit demand at the level of the individual bus stop controlling for service frequency and service quality. To address overlapping bus stop service areas, a geographic information system is used to measure the accessibility of each parcel to each relative to other accessible stops. This is an improvement over current methods where ridership is related to potential transit demand by intersecting block group population with a one-quarter mile buffer around transit stops.
