Spatial integration and accessibility considering urban sustainability patterns: Historical Islands of Istanbul

This paper aims to try to understand the determinant factors on Istanbul Princes’ Islands, based on sustainable urban patterns such as: (1) Axial Analysis; (2) Segment Analysis; (3) Correlation Analysis; which are mostly considered with the traditional accessibility measures of the Space Syntax method. Theoretically, the integration measure shows the cognitive complexity of reaching a street, and promises to ‘predict’ the pedestrian use of a street. This paper will consider the most and the least integrated areas of land use analysis concentrated on the location, size and type of different land uses; including the attractions in buildings. Terrain slope is also an important factor to evaluate walkability for these islands. Segment angular analyses have been done in different meters. These measures visualize angular integration at a radius of 400– 1000 meters, which refers to the linearity of each segment in relation to all other segments within these measurements. As for the result of footpath quality, accessibility to and within these islands has been measured to understand and compare accessibility measures.
