In this paper, spatial and statistical analysis methods were integrated to analyze the spatial accessibility, user population, and coverage of the Light Rail Transit of Addis Ababa. Stations were found to be the least accessible due to five types of land use and road network-related causes: government and social institutions with large area compounds, low road network density, open spaces devoid of road network, natural barriers such as water courses and large area public squares. The study explicitly revealed stations with overlaps in their service areas as well as stations having neighborhoods which are uncovered with the current service areas, i.e., 4.7 km² and 19.9 km² uncovered areas are found within walking distances of 1200–1500 m and 1500–2000 m, respectively; nonetheless, stations have fairly adequate coverage within 400 m and 800 m walking distance. Depending on the causes, stations were grouped into three categories. Service area-based determination of potential users is estimated to be 888,502, while the total number of the daily average actual users is around 67,624. Generally an increase in the accessible population is associated with an increase in the service area coverage. However, the population accessibility and service area coverage do not directly imply more number of actual users. Stations with large overlap of service area have reduced number of actual users due to the fact that the accessible population is divided between shared stations. Therefore, unnecessary large service area overlap is a wastage that does not contribute to more number of users. Future studies in the current study area might focus on considering the nexus between the accessibility and modal share as well as the long-term dynamics of the population of users.

亚的斯亚贝巴轻轨交通的空间可及性分析：以东西走廊为例

本文结合空间和统计分析方法来分析亚的斯亚贝巴轻轨交通的空间可及性，用户人口和覆盖范围。由于五种土地利用方式和与道路网络有关的原因，车站的可及性最差：政府和社会机构的区域大，道路网络密度低，没有道路网络的开放空间，自然障碍（例如水道和大面积的公共广场。该研究明确揭示了服务区域重叠的站点以及具有当前服务区域（即4.7 km ²和19.9 km ^2）未覆盖的邻域的站点在步行距离分别为1200-1500 m和1500-2000 m内发现了未发现的区域；但是，车站在400 m和800 m的步行距离内具有足够的覆盖范围。根据原因，将工作站分为三类。基于服务区域的潜在用户确定为888,502，而每日平均实际用户总数约为67,624。通常，可到达人口的增加与服务区覆盖范围的增加有关。但是，人口可及性和服务区域覆盖范围并不直接意味着更多的实际用户。由于可访问人口在共享站点之间分配，服务区域重叠大的站点减少了实​​际用户数。因此，不必要的大服务区重叠是浪费，不会增加用户数量。当前研究领域中的未来研究可能会集中在考虑可访问性与模式共享之间的联系以及用户群体的长期动态。
