</span><span lang="EN-US">The emergence of ride-sharing services (e.g., Uber) has created ripples regarding some theoretical and analytical notions in geodata science, urban studies, and transportation research. In this talk, I would like to elaborate on two
empirical studies regarding the relationship between ride-sharing accessibility exemplified by Uber services and built environment characteristics with spatial models in the city of Atlanta, USA.<o:p></o:p></span></p>
<p class="MsoNoSpacing"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNoSpacing" style="text-align:justify"><span lang="EN-US">The first empirical study deals with the i</span><span lang="EN-US">nequality of ride-sharing accessibility from a socioeconomic perspective. The constant concern of
</span><span lang="EN-US">i</span><span lang="EN-US">nequality of accessibility in transportation systems is intensified by the transportation economization process and the digital divide. Without any prior assumption, this study openly explores spatial disparities
of ride-sharing accessibility using both the UberX (the most popular Uber product) and the UberBLACK (the premium Uber product) data. Accessibility is measured by both the expectation and variability of Uber wait time. With spatial autoregressive models, we
find that after controlling for other socioeconomic factors, wealth and race do not have significant associations with Uber accessibility. Additionally, higher road network density, population density, and less commuting time to work correlate with greater
Uber accessibility.<o:p></o:p></span></p>
<p class="MsoNoSpacing"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNoSpacing" style="text-align:justify"><span lang="EN-US">The second empirical study
</span><span lang="EN-US">utilizes the spatial Durbin model to explore the relationship between
</span><span lang="EN-US">ride-sharing accessibility and road network structure from a
</span><span lang="EN-US">network science perspective. The results show that in addition to population density and road network density, larger values of degree centrality and smaller values of closeness centrality of the road network are associated with better
accessibility of Uber services. However, the effects of betweenness centrality are not significant. Furthermore, the heterogeneous effects of network measures on Uber accessibility are found.<o:p></o:p></span></p>
