Özet

Purpose
The present study aims to analyze the accessibility and adequacy of the emergency assembly areas
(EAAs) in Kadıköy which has the highest ratio of at-risk buildings in Istanbul.
Design/Methodology/Approach
In this study, accessibility and adequacy of the EAAs are analyzed. To analyze the accessibility
network analysis carried out within a geographic information system (GIS) program is 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.
Findings
According 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/Implications
The research was limited to Kadıköy which has the highest ratio of at-risk buildings in Istanbul.
Originality/Value
When 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.
