Abstract
It is well understood that, infrastructure is a profound determinant of nationhood, a measure of a country success on the world stage. Among the broad infrastructure parts, this study focuses on the network of road transport structure. The true goal of urban road network is to have access and link to a destination places. However, providing efficient road transport for the ever increasing demand is a challenge in developing country cities, like Addis Ababa. Thus the need to evaluate current road network efficiency is a solution to identify opportunities and deficiencies. Thus, this study assesses the existing road network performance, aiming for effective road transport service to all group of society in the Arada sub-city. In order to investigate road network structure, the research employed GIS techniques. The data collection used was a secondary source from Addis Ababa City Road Authority and several Arada sub-city offices. Arada sub-city being as a Central Business District area of Addis Ababa, used as a hub of transportation of the city and experiences low level of road network performance.
The overall findings of this study revealed that despite the fact that an efficient road transport service is the best way to maximize urban mobility, in reality this mode of transport is in a critical condition with in Addis Ababa and in Arada sub-city. There are service deficiencies in some part of the study area, particularly areas that are found far from the centroid of the sub-city suffers from lack of efficient road transport infrastructure and roads in the central area have a capacity limitation. The research has also identifies the low level of road network condition. Further, recommendations are made to improve the existing road network structure considering proximity and accessibility objective that enable the goal of transport system.
