Accessibility to transit, together with other important system characteristics such as network coverage and frequency, is a crucial driver of modal choice for urban commuting. In turn, commuting is a major driver of energy consumption and of socio-environmental externalities in cities. So far, few quantitative and comparative assessments of paratransit in cities of Africa have been carried out due to data scarcity and the prevalence of informal services. Here we leverage the recent release of General Transit Feed Specification (GTFS) data to produce comparative metrics of accessibility, network, and service quality of paratransit in seven major cities in sub-Saharan Africa (Abidjan, Accra, Addis Ababa, Freetown, Harare, Kampala, Nairobi). Our results allow for a first-order assessment and comparison of different crucial paratransit characteristics in these cities, shedding light on transport inequality and urban segregation dynamics. The analysis and metrics produced can support transport systems planners in major cities of low-income countries. Further research should focus on approaches for overcoming the residual data limitations and expand the quantitative understanding of paratransit.

交通的可达性以及其他重要的系统特征，如网络覆盖和频率，是城市通勤模式选择的关键驱动因素。反过来，通勤是城市能源消耗和社会环境外部性的主要驱动因素。迄今为止，由于数据稀缺和非正规服务的盛行，很少对非洲城市的辅助公交进行定量和比较评估。在这里，我们利用最近发布的通用公交馈送规范 (GTFS) 数据生成撒哈拉以南非洲七个主要城市（阿比让、阿克拉、亚的斯亚贝巴、弗里敦、哈拉雷、坎帕拉，内罗毕）。我们的结果允许对这些城市中不同的关键辅助公交特征进行一阶评估和比较，揭示交通不平等和城市隔离动态。生成的分析和指标可以支持低收入国家主要城市的交通系统规划者。进一步的研究应侧重于克服剩余数据限制的方法，并扩大对辅助客运系统的定量理解。
