Transit deserts can result from the inequitable distribution of resources and services, and people living in transit deserts have limited access to transportation system. The aim of this study was to perform spatiotemporal data analysis to identify transit desert areas in Seoul in three steps. First, the transit gap between peak and off-peak hours is evaluated and various spatial changes in each temporal transit desert area are identified. Second, a spatial analysis is conducted to identify transit desert and transit oasis areas that emerge during peak hours. Lastly, an independent T-test is conducted to identify how the socio-economic characteristics of transit deserts and transit oases are statistically different. Our analysis show that, transit deserts changed across space and over the time in Seoul. Furthermore, transit deserts in general appear to be associated with socio-economically vulnerable residential areas.

过境沙漠可能源于资源和服务的不公平分配，生活在过境沙漠中的人们获得交通系统的机会有限。本研究的目的是进行时空数据分析，以通过三个步骤确定首尔的过境沙漠地区。首先，评估高峰和非高峰时间之间的交通差距，并确定每个时间过境沙漠地区的各种空间变化。其次，进行空间分析以确定高峰时段出现的过境沙漠和过境绿洲地区。最后，进行了独立的 T 检验，以确定过境沙漠和过境绿洲的社会经济特征在统计上有何不同。我们的分析表明，首尔的过境沙漠随着时间和空间的变化而变化。此外，
