Accessibility to Cope with Disasters by Using Network Analysis Techniques: Example of Fatih District, Istanbul

14256

Graph theory is an important concept in the management and the relationship of linear structured features. On the basis of this theory it is possible to manage various linear engineering structures from road network to the pipeline with the network analysis techniques undertaken as part of Geographic Information Technologies. With network analysis techniques on the road network, the shortest path analysis, access to the most appropriate facilities, determining service area and so on can be determined. Vulnerability is the characteristics of any system or assets that cause exposure to bad effects of disasters. Capacity to cope with disasters that is important features of vulnerability is related to access utilities such as medical facility, blood banks, and hospitals after disaster. Characteristics of access routes and access time to hospital or medical care service of injured or emergency cases affects the duration of the treatment of disease or injury. In general accessibility defines as the convenience of people and commercial elements to reach the intended facilities, products and activities. Thus access to medical facilities was analyzed in the selected application area in order to cope with potential disaster situations. In these study, alternative approaches were determined to find the best route by using GIS analysis techniques.
