    Gis-Based Multi-Criteria Approach for Land-Use Suitability Analysis of Wind Farms: the Case Study of Karaburun Peninsula, Izmir,-Turkey
    (Izmir Institute of Technology, 2015) Sediqi, Khwaja Jawid; Özdemir, Semahat; Saygın, Mustafa Ömür; Saygın, Mustafa Ömür; Özdemir, Semahat
    This study presents a GIS-based multi-criteria approach to identify the most preferred or suitable site for wind farms development in Karaburun Peninsula, İzmir. Criteria for analysis have been identified based on literature review and experts’ opinions. The selected criteria include environmental, technical, and economic as well as social factors. In order to estimate the weights or relative importance of the criteria, the pairwise comparison method in the context of Analytic Hierarchy Process (AHP) is implemented. The overall suitability of the study area is determined through the Weighted Overlay method, which is a sufficient weighted approach in geographical information system (GIS) environment. The outcome or suitability map is classified into five scored classes from the most suitable to less suitable and restricted area. On the whole, as the selection of optimal site for the wind farm development is a multi-dimensional process, this thesis intends to consider the following three significant subjects; (a) evaluating and identifying the most influential criteria for land suitability analysis of wind farms, (b) applying AHP as a multi criteria decision-making method to determine the criteria weights, (c) utilizing GIS as a tool to overlay the overall criteria and consequently to identify the potentially suitable location for the wind farms development. Regarding to the above mentioned, eight the most influential available criteria, which are consisted of wind potential, distance from preservation area, distance from settlements, forest, slope, elevation, distance from roads, and agriculture area are identified. Base on pairwise comparison different weights for each criterion is determined. Finally, by using GIS the suitability map for the study area is provided and the result compared with the existing wind farm locations.

    Interaction of Urban Fringe and Transportation System: Istanbul Case
    (Izmir Institute of Technology, 2007) Günay, Emel; Saygın, Mustafa Ömür; Saygın, Mustafa Ömür
    Nowadays, urban sprawl is common problem of all cities. Decentralization of housing with low density and jobs into urban fringe areas is considerable development Sprawl is blamed a wide range of problems likewise wasteful use of land, air pollution, dependence on car, increased traffic congestion, lengthened travel distance and time, but it is not clear explaining how urban sprawl affects travel behavior in Turkey?The aim of the thesis is to identify the influence and importance of urban sprawl on travel behavior in Turkey. Firstly literature survey on urban sprawl and urban fringe was examined. Geographic Information System was used to define and map urban sprawl. Daily trip production in sprawl and urban core was analyzed. In addition daily travel behavior was inquired. For this study, 2007 İstanbul Master Plan Household and O-D survey was also used. It allows comparisons travel behavior between sprawl and urban core area.The results confirmed that there is no much difference on socio economic situation between people living in urban sprawl area and people living in urban core area. However using of private car is higher rate in sprawl area than urban core. In addition sprawl population drive more time and distance than urban population. The results provide important insights into the importance of sprawl on transportation and suggest that transportation system can be adversely affected to the extent that cities continue to expand to urban sprawl areas as wanton.As a consequence, sprawl effects İstanbul transportation as negative because sprawl affects travel behavior. This situation creates increased private car ownerships and traffic congestion. To solve this problem and many other problems in transportation related sprawl, studies on transportation and master planning should be considered sprawl fact.

    An Assessment of Spatial Relationship Between Lung Cancer Incidence Rate and Quality of Urban Life: Izmir Case
    (Izmir Institute of Technology, 2013) Özkan, Sevim Pelin; Saygın, Mustafa Ömür
    The study assesses spatial clusters of lung cancer incidences within Izmir province on the basis of districts and also neighborhood using an objective sets of quality of life indicators. Lung cancer data, approximately 18.000 cases, were acquired from the Izmir Cancer Registry Center (ICRC) between the years of 1992-2007. Cases have been confirmed in terms of accuracy by World Health Organization (WHO). As objective indicator data, point source air pollution data acquired from the Izmir Metropolitan Municipality database between the years of 1993-2007. Besides, socio-economic statistics data were obtained from Turkish Statistical Institute (TSI) regional indicators (2000,2007) and Izmir Metropolitan Municipality city health profile (2007). The datasets were used to determine whether there is a significant spatial relationship between cancer case density and environmental contamination. This thesis uses spatial statistical models and Geographical Information System (GIS) techniques to analyze population-based cancer incidence rate. Additionally, Age Standardized Incidence (ASR) of the lung cancer was calculated. Spatial autocorrelation technique was performed to investigate local distribution of lung cancer. Results of the study suggest that spatial clusters of lung cancer were detected in geographic locations with low level environmental quality and high level socio-economic profile. Then, the results are discussed in terms of life quality and environmental quality of Izmir. The results of this study are useful for interdisciplinary researchers, epidemiological studies, policymakers and governmental agencies in terms of health and environmental assessment, regulation and control of spatial strategies.
