The Evolution of Built Environment through Transit Oriented Development in the East Africa

With the rapid advancement of urbanization, “big city diseases” such as traffic congestion, environmental pollution, and land shortage have become increasingly notable. Specifically, transit-oriented development (TOD) has emerged as one possible solution to sustainable urban development and the key to promoting green transportation. Consequently, many cities and regions have embraced the concept of transit-oriented development. At present, the researches on the TOD built environment mainly focus on the cross-sectional analysis of the built environment. Although these researches reveal the impact of TOD mode on the built environment, it is difficult to determine the evolution of the built environment. Furthermore, the current research concentrated on the TOD model in Americas, Europe, and Asia, while there is little discussion on that in Africa. In view of this, this study analyses the evolution of the TOD Built Environment based on the built environment data of Addis Ababa, Ethiopia. This study verifies that the rail transit infrastructure with the TOD mode does have an impact on the built environment along the route, including the density and diversity of commercial, residential, medical, and educational facilities within the pedestrian range of the station.
