Accessibility patterns of Istanbul’s Hans region as a traditional urban trade district
Sustainable Development and Planning VII, 2015
This study aims to understand the determining factors on pedestrian flow based on sustainable urban patterns related to factors such as spatial configuration, attraction of opportunities, and topological issues (slope of the land) that affect traditional accessibility measures. In this context the space syntax theory and other morphological techniques present some measures that could aid improvement of the environmental quality of pedestrian accessibility as well as helping to understand the retail dynamics of Hans region. The space syntax configurations are used here to make several important observations configurationally ones obtained through the axial map, land use effects and the pedestrian flow, slope degrees where the trade areas are more in demand, pieces of land where natural movement occurs in highly integrated zones. Ten important trade axes are chosen where Han buildings are densely settled for spatial configurations since that area was found to be a highly integrated district in all historical peninsula's global integration analysis. Land use analyses have been conducted to understand the diversity of human activities. Second, weekday and weekend pedestrian counts have been recorded including children, teenage, young and old people without considering gender difference. Terrain slope is also an important factor for Hans region therefore slope measures have been calculated of these streets. Correlation analysis of pedestrian counts and the local integration values have been done to understand the relationship between them. The outcomes of this study reveals the role of pedestrian movement in traditional trade areas and integration measures in the network are measured and presented graphically.
Pedestrian Movements in Commercially Transformed Residential Areas: Levent Bazaar, Istanbul
International Urban Design Conference: Cities, People and Places - Proceedings, 2013
Urban spaces confront with transformation process depending on growth and development dynamics of the cities. This process can occur within both physical and socio-economic contexts; besides, built environment can be conserved while socio-economic transformation is obtained. With growth and development of the central business district (CBD) of cities; commercial transformation of residential areas and change of their spatial identity have become a very common phenomenon. This spatial change naturally affects the target user; therefore, accessibility and intensity of pedestrians increase accordingly with the new transportation policies.
Interpretations and Comparisons of Pedestrian Movement and Land Use Activities in Kadıköy Region Using Space Syntax Method, 2022
Prevailing theories of urban form suggest that pedestrian movement characterizes land uses, which in turn take advantage of 'natural movement' generated by the grid configuration. The present paper investigated a configurational method of the urban grid for transit movement and as the main generator of movement patterns. A morphological method, namely space syntax analysis, was employed in the Kadıköy region, with an aim to understand, how the pedestrian movement was generated via a vis the urban layout. Axial analyses include defining the central cores of the settlement and determining the most intense movement in those centers, whereas segment analysis determines the scales and limits of the movement towards the points in such centers. Accordingly, axial maps were developed and analyzed in order to forecast the general functioning of Kadıköy grid. Measures of 'axial integration' for properties of the grid and segment analyses in micro-spatial characteristics of Kadıköy were used to investigate transit movement with an aim to gain an insight into movement patterns. Furthermore, correlation of segment and axial analyses were also performed to better simulate the movement. The present paper aimed to investigate the density of pedestrian movement by the characteristics and syntactic properties of urban space that identified limitations in the prediction of movement.
The influence of architectural configuration on the pedestrian network in Büyük Beşiktaş market
AZ ITU Journal of the Faculty of Architecture, 2015
A study of trading can help us understand a wider range of organizations and building types. Many shopping centers have been built in Istanbul over the past twenty years. Although these privately owned places serve as social spaces and provide an area for many public activities, their size and close proximity separate them from the urban environment and choke off daily urban street life. Buyuk Besiktas Market, which is selected as the subject of the case study has a specific architectural form. Multiple entrances and a conductive interface converts the building and especially the ground floor into a common area and urban domain that hosts concerts, urban activities and special meetings. The study seeks to understand how does the architectural form and syntactic pattern of the outer layer play a role in changing the pedestrian network inside the building and how do basic architectural elements such as inner courtyards and open spaces affect pedestrian flow and preferences? The research procedure is based on two main steps. The first step comprises a gate count of the people passing through the gates and a density analysis. The second step is to analyze the architectural configuration using Syntax 2D program developed by scientists at the University of Michigan. The results of the study support the idea that particularly for multi-entrance buildings, the urban environment can be more dominant or at least effective in manipulating the natural movement in buildings. Independent from the structure of the building, the configuration which was set by urban dynamics is so dominant .
This paper aims to examine to understand the determinant factors on Istanbul Princes’ Islands, based on the sustainable urban patterns as (1) Axial Analysis, (2) Segment Analysis, and (3) Correlation Analysis; which are mostly considered with the traditional accessibility measures of 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 how walkable for islands to see how walkable these islands are. Segment angular analyses have been done in different meters. These measures visualize angular integration at radius 400-1000 meters, which refers to the linearity of each segment in relation to all other segments within these meters. As for the result of footway quality, accessibility to and within these islands have been measured to understand and compare accessibility measures.
There has been a growing interest in the transformation of major urban squares in Istanbul in recent years. This heightened trend in the urban renewal of prominent areas within the city has led to multiple pedestrianization projects aimed to revitalize urban cores in terms of infrastructure and pedestrian activity. Despite their strategic schemes, these proposed projects lack an objective methodology to implement systematically at various scales. This paper focuses on the walkability of 3 historical urban squares in Istanbul by analyzing their street configuration and land use compositions and comparing it with the levels of pedestrian movement. The main objective of this study is to determine the existing relationship between space allocation and pedestrian activity and to assess the efficiency of proposed pedestrianization projects developed by local authorities for these areas. Overall, the analyses presented in this study emphasize the importance of measures of street connectivity in walkability studies. It is shown that street network configuration; measured using both metric and directional connectivity measures at the road-segment scale is strongly associated with pedestrian movement when controlling for land use compositions at the parcel-level. Based on the spatial analysis and statistical models produced for the research area, a pedestrian-oriented strategical framework that takes into account the existing spatial configuration, parcel-based land-use compositions, as well as pedestrian movement distributions within the areas is proposed for the study areas and their surroundings. With its systematic methodology, efficient spatial models, and strategical approach, this study is anticipated to be used as a unique design framework for prospective urban design and pedestrianization projects for Istanbul.

This study combined space syntax metrics and geographic information systems (GIS)-based built-environment measures to analyze pedestrian volume in different land-use zones, as recorded in unique public data from a pedestrian volume survey of 10,000 locations in Seoul, Korea. The results indicate that most of the built-environment variables, such as density, land use, accessibility, and street design measures, showed statistically significant associations with pedestrian volume. Among the syntactic variables, global integration showed a statistically significant association with the average pedestrian volume in residential and commercial zones. In contrast, local integration turned out to be an important factor in the commercial zone. Therefore, this study concludes that the syntactic variables of global and local integration, as well as some built-environment variables, should be considered as determinant factors of pedestrian volume, though the effects of those variables varied by ...

Spaces, designed or non-designed, has both morphological and cognitive characteristics. Sometimes they are overlapped onto each other, whereas sometimes the cognitive characteristics lead totally the opposite side than morphological characteristics. In this paper, this situation will be examined. The urban scale is chosen for the examination, as it is the display scale of the daily life of a city. The urban niches are the main focus point of the paper. 'Urban niche' defined as the spaces in the urban area that provides personal space to people, in the areas that are causing environmental stress due to crowding. 'Urban passage' is proposed as the physical equivalent of 'urban niche' in city scene. Further questions will be examined through the paper: Does the location/orientation of the passage affects their usage? Do configurational aspects affect the everyday usage? Being a metropole, having more than 5-6 central points and having 'crowding' problem as the main problem of the daily life of the city, make Istanbul, the most suitable city for the examination of the 'urban niche' that defined before. For the case study, 2 passages in Istiklal Street are selected: Avrupa Passage and Hazzopulo Passage. Istiklal Street is a backstage for an intense pedestrian flow most of the time and these two passages have certain characteristics in all the passages on the Istiklal Street for their functions, cognitive aspects, architectural configurations and the usage frequencies. The configurational characteristics of these passages and their interrelation with Istiklal Street will be examined. After the observation and on-site analysis, the morphological results and this observation data will be overlapped and interpreted in the frame of configuration-movement-attractors perspective. In this research, the analysis of the movement of pedestrians both to and through the passages, and space usage will be investigated by the data collected on-site observations. The passages will also be analysed with 'University of Michigan' licensed 'Syntax 2D' software in order to get the syntactic values. The syntactic and observation data will be used comparatively. In conclusion, the features that affects the frequency of pedestrians in the passages will be examined in this study. Two passages will be compared through the morphological-configurational characteristics and cognitive characteristics by using syntactical analysis and on-site data collection.

Cities are organisms that live in a balance of continuity with the structures they possess and the urban open spaces that connect them. For this organism, staying alive and healthy is possible if urban dwellers, who are the users, utilize the spaces in a manner that preserves their integrity and locate each space in mental perception. Research problem/aim; Squares, which are one of the urban open spaces, are the breathing centers of the city that play important roles in maintaining this integrity. This study aims to test the relation of squares and pedestrian movement for each square and for the whole historical city. Method; In the present study examining the squares and their relationships in the historical city center of Konya province, 7 squares that have a semantic relationship resulting from being located on a specific axis with one another were analyzed with respect to pedestrian use and the respective physical characteristics of the squares. The main criteria defined in the ...
