Abstract
This project designed aiming for equitable road network structure for both people of
urban and peripheral areas. In order to investigate road network structure, the research
employed GIS techniques and some statistical analysis by Trans-CAD for cross sectional
efficiency of the system. Types of data i.e. data obtained through methods such as, socio
economic data, land use map, current road network and master plan road network. The
result of this project indicated that road density, higher trip production and attraction is
exhibited in the central areas (characterized by high population and important socioeconomic
activities of the city including freight terminals, service centers and schools).
As settlements in Addis Ababa are mainly established along the road network, the road
length per unit person in the central areas is found to be low. Proximity to the roads
within the central areas is less than 500m, allowing more people to access these roads.
However, in the periphery, people have to travel more than 1km to access the existing
road infrastructure, indicating the inadequacy of the system. The Mobility Index
indicated that have high values in the South-East and Western parts of the city. The
overall conclusion obtained from the indicators show that there is less road
infrastructure in the peripheral regions of the city and the central area clearly has a
capacity limitation.
