Accessibility is regarded as one of the most important goals in the transportation policy. This study focuses on job accessibility by public transit systems which have been the topic of interest within the Spatial Mismatch Hypothesis of John F. Kain (1968). Despite the importance of accessibility in transportation and land-use planning policy and the popularity of job accessibility measures in evaluating the impact of accessibility on employment outcome of low-income households, some scholars (Geurs & Van Wee, 2004; Grengs, 2010) criticize the ambiguous definition and the crude measure of accessibility.

In particular, within the variety criteria or indicators of accessibility proposed by many scholars, the distinction of “perceived” accessibility from “objective” accessibility (Morris et al., 1978) is missing from many of the current practices of measuring accessibility. According to Morris et al. the objective accessibility is the supply characteristics of transport infrastructure and systems and mobility capacity of individuals whereas the “perceived or revealed” accessibility measures the actual use of services or the determinants of behavior. The combination of these two types of accessibility measures is rarely applied in the studies and current practices take either one form or the other.

Studies on transit ridership factors propose the demand for transit follows the basic consumer economics theory that the ridership is a function of the utility of the trip and its cost (Taylor et al., 2008). As the utility of the trip and its cost are largely how one perceives the attributes of the neighborhood environment and transit systems, this study uses the factors of ridership invariably as the factors of accessibility. The findings of this study are expected to contribute to better understanding of the impact of neighborhood environment on job accessibility and further applied to examine the impact on employment outcomes.
