Abstract
Purpose The present study aims to analyze theaccessibility and adequacy of the emergency assembly areas (EAAs) in Kadıköywhich has the highest ratio of at-risk buildings in Istanbul. Design/Methodology/ApproachIn this study, accessibility and adequacy of the EAAs are analyzed. To analyze the accessibilitynetwork analysis carried out within a geographic information system (GIS) programis used. Through an accessibility analysis, the ratio of the population that resides within 500 m walking distance of each EEA was ascertained. Furthermore, an adequacy analysis was carried out to measure the size of each emergency assembly area, and its adequacy for the population within its catchment area was analyzed. In addition, an accessibility and adequacy analysis were made of the social infrastructure facilities that have been defined as second-level emergency assembly areas.FindingsAccording to the research findings, 57 percent of the current population of the district resides within 500 m of one or more of Kadıköy’s 73 EEAs. It was found also that the emergency assembly areas accessible by three-quarters of the population within 500 m could be considered inadequate. Based on these findings, it was concluded that emergency assembly areas should be of adequate size, away from disaster risks and accessible to all residents, and that the standards for the open and closed areas within the emergency assembly areas should be defined in legislation and included as mandatory in future plans. Research Limitations/ImplicationsThe research was limited to Kadıköy which has the highest ratio of at-risk buildings in Istanbul. Originality/ValueWhen evaluated alongside relevant studies regarding EAAs, the present study can be said to contribute to literature in its analysis of both the accessibility and adequacy of the existing EAAs and secondary assembly areas, taking a holistic approach, the study makes use of a network analysis method in the GIS program to identify the number of people living in each residential structure within the Kadıköy district. In addition, the study seeks to contribute further to literature by measuring the accessibility of social and technical infrastructure within the city planning discipline through a network analysis.
