Abstract
This research paper investigates the spatial accessibility of public transportation networks in Addis Ababa, Ethiopia, using Geographic Information Systems (GIS) in the context of time and distance. It highlights the underestimation of nonmotorized travel and the need for accessibility-based planning to address road problems and low transport accessibility in developing countries. This research's main objective is to investigate the public transportation network's spatial accessibility in Addis Ababa, Ethiopia: the case of the Mexico to Hayahulet Route corridor. The methodology is particularly meticulous in terms of measuring the accessibility of bus stops, with a specific focus on walking distances regarded through the average comfortable walking paces and travel time to access different services and activities to be reached within a 15-minute walk. Based on the analysis the first method results illustrate, the existing Bus Stations from Mexico to Hayahulet are accessible to 31300 (62.6 %) individuals settled in 2.79 ha but less than half of the population in that area which is 18700 (37.72 %) individuals settled in 1.68 ha does not have an access to the specified road with a 500m travel distance standard. The accessibility based on time result showed that, around 68.5% of the population can access the bus stations within the standard limit whereas 31.5% of the population will have to walk an extra mile to access the nearest public bus stations. Further research should be conducted in other city areas to create a comprehensive view of public transport accessibility across Addis Ababa.
