Accessibility of spatial networks: Using ArcGIS network analyst and space syntax to investigate accessibility to urban facilities
(Instituto Superior Tecnico, Departamento de Engenharia Civil, Arquitetura e Georrecursos, 2017) Özer,Ö.
Accessibility is a critical objective in the field of planning, particularly for urban facilities such as education and health services. Among many models and techniques that calculate accessibility, this study focuses on network analyst tool of ArcGIS and space syntax methodology. In the network analysis of ArcGIS, it is possible to calculate service areas for individual urban facilities within given distance/time limits. Space syntax measures on the other hand, help to understand the overall accessibility dynamics of the network. This study aims to associate space syntax based accessibility evaluation and service area measures of ArcGIS in the city of Mersin, Turkey. Mersin is one of the most populated cities of Turkey with more than 1.5 million people. It has a sloping topography which has affected the development of both the road structure and the settlement structure of the city. Apart from the urban centre, there are villages with rural character in mountainous parts of the city that do not have proper access to most urban facilities. Health and education services are of vital importance and access to these facilities is a must for both urban and rural settlements. Therefore, accessibility of these particular facilities within the Mersin Municipal Area is the main focus of this study. In 2015, the Greater Municipality of Mersin initiated the preparation of an urban development plan for Mersin. Urban development plans usually consider accessibility as a means to organize general transportation flows but not as a network issue that would affect individual accessibility of facilities. Therefore, it is important to understand the direction of development in cities before planning them. In order to comprehend development trends and needs of urban facilities, two types of accessibility analyses were carried out in Mersin. Firstly, health and education facilities were assessed using network analysis toolset of ArcGIS, separately for hospitals, school of medicine and small scale health facilities for health services; elementary schools, middle schools and high schools for education services. Secondly, segment based space syntax analysis was executed, in which integration measures were inspected. Comparison and integrated evaluation of results of these two types of analyses are believed to serve to an improved comprehension of the morphological spirit of Mersin. Further analyses on such issues would play a crucial role in planning.

Human perception in the libyan built environment: Al- Khums and Bani Walid cities as case studies
(ArchNet, 2017) Agael,F.; Özer,Ö.
This paper is concerned with the identification of different influences on the built environment, and those which have a physical and psychological impact on people. The aim of this study is to analyze the impact of the built environment on the lives of people. The interrelationship between people and built environment is based on human perception. This research will explore this relationship further in order to develop a clear understanding of the ways in which architecture may influence peoples' perceptions and experiences. Additionally, the research entails a comparison between two important theories: the first is an Image of the city derived using the Mental Map Theory; the second is related to Space Syntax Theory. The two theories will be applied in two different cities in Libya with the aim of assessing the importance of their interrelationship and how it may be understood more clearly. The paper will also provide guidelines for improving urban design and planning standards with the end goal of producing a high quality perception by those who actually use the space. Moreover, it concludes with a number of research avenues that should be pursued to answer how the properties of built environment affect human perception. © 2017 Archnet-IJAR.

Measuring walkability in istanbul galata region;
(Istanbul Teknik Universitesi, Faculty of Architecture, 2015) Özer,Ö.; Kubat,A.S.
Pedestrian movement is one of the critical issues in urban design, but yet a determinate method for evaluating the attractiveness of an area for walkability has not been established. This paper presents the findings of a comprehensive study on walkability, developed on a historical centre of Istanbul, named Galata that has become segregated in recent years. This study has researched the possible effects of the environmental variables on the levels of activity in urban spaces. The aim is to shed light on key variables that affect the attractiveness of an area for pedestrian movement, which in turn can help to develop an objective methodology to evaluate walkability. Within the context of the study, the existing pedestrian movement patterns in Galata have been observed and a range of variables have been determined to analyze the relationships. The data recorded in this study have been analyzed with a multiple regression analysis, in which pedestrian movement levels are considered as the dependent variable. The result of the regression analyses has generated a model that accounts for 0,60 of the variation in pedestrian movement. According to the findings of the model, pedestrian movement levels have been explained with three out of five variables: safety, accessibility (space syntax integration values) and land use pattern. The method and the findings of this study constitute an analytical model that could shed fresh light for future research on walkability as well as for evaluating proposals to regenerate historical city centers that have lost their vitality. © 2015, Istanbul Teknik Universitesi, Faculty of Architecture.

Urban transformation through property-led regeneration: A case of building renewals in Istanbul
(Istanbul Teknik Universitesi, Faculty of Architecture, 2018) Kisar Koramaz,E.; Koramaz,T.K.; Özer,Ö.
Urban transformation is a prominent topic within Istanbul’s urban planning agenda. Transformation process of the city falls under the scope of academicians and the related authorities; and is a focus of debate from different perspectives in daily life. In this atmosphere, centralised policies promote construction facilities as the leading economic sector, and the legislation sets the legal framework facilitating transformation processes. This transformation in Istanbul occurs in two forms; as area-based regeneration projects and single building renewal processes. Area-based regeneration projects have long been examined due to their widespread effects, however single building renewal also leads to transformation over the long term. The motivation behind this paper is to examine the single building renewal process by means of a case study – Bakirkoy, which is one of the sub-centres of Istanbul. In this context, the paper aims to construct an analytical evaluation of the regeneration process in Bakirkoy and tries to evaluate the process linking it with critiques of property-led regeneration debates worldwide. This paper covers a periodical evaluation of this process by attempting to understand the urban transformation pattern by means of a descriptive spatial analysis, and a discussion of recent policies in Bakirkoy case. © 2018, Istanbul Teknik Universitesi, Faculty of Architecture.
