A Spatial Analysis of Transit Deserts and Infrastructure Gaps in Oklahoma City

Abstract: Transportation equity ensures equal access to essential services and opportunities for everyone in the community. However, disparities in urban transit systems often disproportionately affect transit-dependent populations. This study examines the presence of transit deserts in Oklahoma City, where the demand for public transit far exceeds the available supply, adversely impacting residents who lack access to personal vehicles. Despite the city’s rapid growth and development, the public transit infrastructure has not kept pace, resulting in significant service gaps. This research aims to identify and analyze these transit deficiencies through the application of geo- spatial data, aiming to understand disparities between transit supply and demand. Utilizing a combination of statistical methods and spatial analysis using ArcGIS Pro and RStudio, the study assesses transit scenario at the block group level. The findings indicate that the transit-dependent population in Oklahoma City constitutes 13.24% of the city’s total population. The analysis highlights significant transit deserts, particularly in suburban and less densely populated areas, despite a higher concentration of transit services in central urban regions. This uneven distribution underscores a disparity in transit resource allocation, with higher-demand urban centers receiving more comprehensive services compared to the underserved peripheral areas. This research offers actionable insights for policymakers and urban planners to address transit inequities, with the goal of fostering a more inclusive and equitable transportation system in Oklahoma City. Future research should further explore the interplay between transit services and urban land use to better understand the broader implications of transit infrastructure on community well-being and sustainability.
