ANALYSIS OF LAND USE AND TRANSPORTATION DEMAND INTERACTIONS IN ADDIS ABABA: ( A CASE STUDY: AKAKI KALITY SUB CITY)

Nowadays, the provision of appropriate transportation infrastructure and integrated mobility services in the Ethiopian cities, especially in Addis Ababa, is a problem to vehicle operators, the public and the Government in respect of costs, environment and traffic accidents. Specifically, planning transportation infrastructures and integration with land use and coverage of area is a major concern. This research analyzes the land use and transportation demand interaction in Addis Ababa considering the Akaki Kality Sub City as a Case Study. Transportation demand analysis in conjunction with studying the extents of urban expansion along with land use pattern changes and analysis on interactions of the two were the major undertakings that were dealt with in the study. It assessed and analyzed the continual day-to-day increment of public transportation demands and transportation problems due to high variability of land use change and high rate of urban expansion that are taking place around the peripheral of the Addis Ababa City. The four step transportation demand model was utilized in the study to analyze the present and future land use patterns of the city, Satellite image classification along with analyzing the change of land use for the past twenty-nine (29) years were performed. To carry out the study successfully; primary, secondary, and tertiary data were collected. In analyzing the spatial data, the Arc GIS 10.1 software was utilized. Similarly, statistical, mathematical, and graphical analysis was dealt with. To make the research specific and effective, six major destinations of the Akaki Kality sub-city passengers were selected and dealt with. By analyzing the data, adopting different equations, models, and calibrate parameters; it was found that the population of the Addis Ababa city has been growing by 3.8% yearly while the physical built up area has been correspondingly increasing by 3.2%. On the other hand, due to high economic growth and people’s interest in owning private cars, the number of vehicles has been increasing by 13.5% yearly causing the yearly average urban mobility increment by 10 %. However, the road network coverage has grown only by an average of 4.1% per year which cannot accommodate the increasing transportation demand and vehicle fleets. This results in continual day-to-day transportation and social problems of the city like congestion, traffic accidents and environmental impacts
