摘要:The sprawling masses of cities like Los Angeles, Chicago and Istanbul, driven by car-culture, need a model that accounts for the car, mass transportation and, in Istanbul’s case, marine links. Urban realms model provides this descriptive and interpretive framework and replaces the models used to address the characteristically single-centered metropolis of prewar decades. In the urban realms model, these urban realms are large selfcontained areas: within which a mix of land uses is such that daily life can be carried on without normal resort to external locations in other realms. There will always be a turning to other realms for some purposes by those living or working near the boundaries between realms. Istanbul is unique because its urbanization rate is higher than almost anywhere else in the world. Human behavior, transportation initiatives, and governmental policy have all been instrumental in their effect on the urban morphology of Istanbul. In this paper, the urban realms model is employed as an analytical framework for Istanbul.
