Car dependency which corresponds to excessive and inappropriate usage of the car itself is becoming a major problem all around the world. It shapes urban areas in such a way that the overall urban form as well as individual activities all develop to accommodate cars. However, introducing nonmotorized modes is seen as a remedy to overcome the car dependency. It offers a chance for retrieving healthy urban environments and healthy social lives and also for revitalizing/enhancing public spaces in cities. This means increasing the quality and quantity of pedestrian areas which have been receiving increasing emphasis all around the world. In this thesis, it is intended to show that pedestrianization can be, and should be, a valid transport policy in growing metropolitan areas that are becoming more and more car-oriented, such as Ankara. As a case study, this study assesses potentials and possibilities for creating a pedestrian environment in Ankara, Tunali Hilmi Street. To do so, detailed pedestrian surveys/analyses including v pedestrian counts, pedestrian movement analysis, pedestrian static analysis and pedestrian space analysis throughout the street and questionnaires with potential stakeholders including pedestrians, shop-owners and taxi-drivers are carried out. Through these analyses, it is assessed whether Tunali Hilmi Street is suitable for such an arrangement in terms of pedestrianization or not. As a result, this thesis makes an emphasis on non-motorization and pedestrianization as a method of preventing increasing car-oriented arrangements and revitalizing city centre for the case of Tunali Hilmi Street.
