    Evaluating the Sustainability of Urban Mobility And Traffic Growth in City of Addis Ababa
    (Addis Ababa University, 2019-05) Yodit, Dejene; Bikila, Teklu (PhD)
    t has been long since mobility became a major issue in Addis Ababa following the enormous horizontal expansion of the city boundaries because of the rapid population and income growth. The current transportation problem in Addis Ababa is at its boiling point, and worsening by the day despite the government‘s attempt to address it. As transport system is an important part of a city, success in insuring mobility can even be an indication of how well the city really is organized. Failure to provide well-functioning transport system causes growing social, economic as well as environmental problems. Spatial sprawl, infrastructural development and increasing vehicular number are concurrent trends that need coordination among actors and policies for sustainable development. Although there are studies conducted to understand and solve the problems related to motorized transport in the city, most of them focus on the conventional approach of improving the physical infrastructure of the transport sector to enhance the service provision by constructing highways, extending road networks and increasing the number of fleet. Measures that differ from the ones with the conventional focus of congestion and mobility should be assed. The general objective of the study is to evaluate sustainability of transport system in Addis. Although Sustainability is difficult to be measured directly, it can be evaluated through a system of parameters and indicators constitute part of this process. A procedural framework was developed to select potential local indicators for the current work. Data were collected using different techniques at various stages. Existing database, unprocessed data from surveys and processed data from spatial studies were among the sources used for data gathering. Indicator parameters are obtained by means of formula calculation, extraction from previous studies or other methods. The score of indicators are then calculated based on the parameter value. In line with the results from the analysis, the sustainability of city transport system scores 2.69 out of 5 suggesting weak sustainable mobility conditions. The results of this application highlight the priorities for the improvement of city‘s sustainable mobility conditions as presented using a spider chart, which gives the disaggregated overview of the mobility performance. Consequently, a shift towards more sustainable modes of transport like public and non-motorized transport is needed. The trend analysis on vehicle growth also confirmed lack of attention for these modes. Most of the trends indicate that the current traffic growth is unsustainable.
