The widespread availability of high spatial and temporal resolution public transit data is improving the measurement and analysis of public transit-based accessibility to crucial community resources such as jobs and health care. A common approach is leveraging transit route and schedule data published by transit agencies. However, this often results in accessibility overestimations due to endemic delays due to traffic and incidents in bus systems. Retrospective real-time accessibility measures calculated using real-time bus location data attempt to reduce overestimation by capturing the actual performance of the transit system. These measures also overestimate accessibility since they assume that riders had perfect information on systems operations as they occurred. In this paper, we introduce realizable real-time accessibility based on space–time prisms as a more conservative and realistic measure. We, moreover, define accessibility unreliability to measure overestimation of schedule-based and retrospective accessibility measures. Using high-resolution General Transit Feed Specification real-time data, we conduct a case study in the Central Ohio Transit Authority bus system in Columbus, Ohio, USA. Our results prove that realizable accessibility is the most conservative of the three accessibility measures. We also explore the spatial and temporal patterns in the unreliability of both traditional measures. These patterns are consistent with prior findings of the spatial and temporal patterns of bus delays and risk of missing transfers. Realizable accessibility is a more practical, conservative, and robust measure to guide transit planning. [ABSTRACT FROM AUTHOR]

Critical food scholars have argued that activists' political ideologies and environmental values are important influences on their food justice projects. However, this body of work has given little attention to religion and spirituality even though religious studies scholars maintain that religious values affect environmental and social action. Bringing together these perspectives considers the way religious values and meaning making intersect with actions toward food justice outside of traditionally religious spaces. This paper draws on qualitative research, including a dozen interviews and 11 months of participant observation, at Franklinton Farms, a nonprofit urban farm in Columbus, Ohio. I demonstrate that Franklinton Farms team members reference diverse religious values and practices when explaining the meaning and significance of their farming. In addition, I argue that they renegotiate their religious values in light of the injustices they see in the food system. By examining religion and spirituality within a secular food space, this paper sheds light on an underexplored influence on whether and how alternative food spaces realize food justice.
