Article Citation - WoS: 3Citation - Scopus: 4Region-Specific Turning Points in Territorial Economic Resilience: A Business Cycle Approach To Turkey(Routledge, 2024) Duran, H.E.; Elburz, Z.; Kourtit, K.; Nijkamp, P.Almost all regional economic resilience studies measure resilience by referring to national time patterns of recessions. This study of region-specific patterns of resilience of 81 Turkish regions in the period 2009–20 and their underlying economic/demographic determinants in regions in Turkey shows that ignoring the different timings of regional and national economy recessions leads to misleading/biased results. The study shows first that provincial employment cycles are asynchronous. Second, the geographical pattern of resistance to the last 2018 economic crisis changes considerably when using province-specific rather than national turning points. Third, those provinces that are more open to trade, export- oriented, highly urbanised, and with a low level of human capital and entrepreneurial activities were more resistant to the recession. © 2023 Regional Studies Association.Conference Object Detection of Urban Change Using Remote Sensing and Gis: Izmir Case(Taylor and Francis Ltd., 2008) Tarhan, Çiğdem; Arkon, Cemal; Çelik, M.; Gümüştekin, Şevket; Tecim, V.This study is an example of how land use changes could be detected via high resolution remotely sensed data. In order to perform "change detection" IKONOS satellite images, belonging to 2001 and 2004, have been used. An automated Graphical User Interface (GUI) has been created for detection of environment. Different image enhancement techniques and a fuzzy inference system have been combined in the GUI. The detection results are classified according to some basic levels such as 20-50% and 70%. Additionally, four different change detection algorithms have been applied which are pixel-based, object based, feature based. These algorithms have been examined according to change detection levels with different image enhancement techniques. At the end of the study, the results have been compared.Conference Object Citation - WoS: 1Citation - Scopus: 1Spatial Point Pattern Analysis of Lung Cancer in an Urban Area: Izmir Case(Taylor & Francis, 2013) Özkan, Sevim Pelin; Tarhan, Çiğdem; Eser, Sultan; Yakut, C.; Saygın, ÖmürIn health area, in order to conduct a reliable analysis of the diseases that threat public health and develop control strategies. This is required to investigate firstly how the disease are geographically distributed, secondly regions where disease is observed more dense, and thirdly their geo-statistical aspects. The aim of the study is to prepare spatially distribution map of the lung cancer cases in Izmir, Turkey, and are distributed on Izmir map via GIS. Spatial statistics are performed and the relations of geographical factors and the cancer data are discussed. Smart maps with tabular data and displaying cancer cases on a spatially distribution maps have been produced as end products. ArcGIS and Spatial Analyst module are used for the study.Conference Object Citation - WoS: 35Detection of Flood Hazard in Urban Areas Using Gis: Izmir Case(Elsevier, 2016) Özkan, Sevim Pelin; Tarhan, ÇiğdemThe aim of this study is to predict the potential flood-hazard areas using Shuttle Radar Topography Mission-Digital Elevation Model (SRTM-DEM). The study area is the province of Izmir. SRTM-DEM of the Izmir Province has 90 m of grid size resolution; 45 m of horizontal accuracy; and 15 m of vertical accuracy. Within this study, obtaining spatial information on flood hazard by using Izmir digital terrain models and by 3D analysis that will help to achieve the regional flood hazard management scheme is aimed. Flood-hazard areas have been identified by the use of digital elevation model covering the study area. The main rivers in the study area are Gediz, Kucuk Menderes and Bakircay that creates the coastal flood plains. In order to estimate the spatial distribution of flood-hazard areas in Izmir, five factors are used: flow accumulation, land use, slope, rainfall intensity, and elevation. The classic hydrological modelling approach was applied to determine the rainfall intensity; rainfall intensity of study region is created with the average amount of total rainfall intensity of fifteen stations in the two basins per minute using the interpolation method (spline interpolation). By the digitizing rivers, topography, flow direction and flow accumulation, as well as the flood detention areas are determined. These factors were combined with the weighted overlay method to determine categorized flood-hazard areas. As a result, possible flood-hazard areas have been determined in the case of Izmir Province.

In this regard, many studies focus on the strong relationship between energy and the environment. This study aimed to introduce the exergy analysis method into the urban planning field to find out the amount of exergy, rather than energy, that can be conserved in a building block when a solar envelope-based design is applied. In addition to the known energy-efficient design parameters, a criterion for the solar envelop method is integrated into a single method. This hybrid method includes taking into account the requirements for orientation, spacing, landscaping, and building form, as well as the building height properties as proposed in the solar envelop method. The solar envelop method depends on understanding the changing position of the sun throughout the day and year. If this dynamic behavior can be a factor in the design of an urban area, environmental friendliness, sustainability, and reduced energy consumption can comprehensively be achieved in cities.Conference Object Citation - WoS: 2Citation - Scopus: 2Contribution of the Personal Rapid Transit (prt) Systems To the Road Safety: a Scenario-Based Comparative Evaluation(Hong Kong Society for Transportation Studies, 2012) Duvarcı, Yavuz; Akpınar, FigenThough the number of "real ground" PRT projects are few, it can be possible to deduce some hypothetical safety conclusions. For the very optimist assumption that the control algorithms will only "allow" them to operate in non-collision mode on the network, the safety figures are re-evaluated for two urban settings: First (1) is the case where the urban design was fully recreated based on PRT system. The other (2) is the hypothetical PRT system would be embedded into the existing transportation system. The two cases of the safety measures and cost figures are compared to evaluate the opportunities and pitfalls by the application of a PRT system via the scenario analysis. By doing so, after description of the present situation, there comes the construction of possible alternative futures to compare with the present one. It can be deduced that, even if the safety figures of PRT system are hypothetical, PRT-based urban environments promise a lot in terms of safety levels (as far as 80 per cent) with, however, the expense of financial burden for the local government. Yet, for low-cost solution, PRT-embedded urban environments also provide promising results compared to "doing nothing" as far as 30 per cent reductions, in accidents in total and 44 per cent in deaths.Conference Object Evaluation of an Integrated Gis-Based Crime Analysis & 3d Modelling for Izmir-Konak Municipality(International Society for Photogrammetry and Remote Sensing, 2011) Tarhan, Çiğdem; Deniz, DenizGIS integrated 3D modelling is crucial for the city planning and design processes because urban modelling is a tool used in virtual environments, and provides convenience to work. Although, the creation and display of 3D city models for large regions is difficult it is vital for planning and designing safer cities, as well as public places. Today, crime is a significant problem in Turkey. When it was compared by years of crime rates, population growth and urbanization rate, an increasing more than in parallel has been observed. This paper aims to discuss GIS integrated 3D modelling affects in urban planning and design, explaining Turkish planning processes with GIS and 3D modelling. To do that, it presents a case study for Izmir Konak Municipality about GIS integrated crime analysis and 3D models of the crime scenes. Izmir crime records has been obtained from Izmir Police Department belonging to 2003-2004 and 2005 (D.Deniz, 2007) are used for districts’ crime map. In the light of these data, the highest rate crime district, Konak, is analyzed between 2001 and 2005 data.Book Part Citation - WoS: 3Citation - Scopus: 4Spatial Transformations in Istanbul Cbd: the Role of Ict?(Information Science Reference, 2008) Geçer Sargın, Feral; Avar, Adile; Velibeyoğlu, Koray; Saygın, Mustafa ÖmürNow with the intensive use of information and communication technologies, many cities around the world are competing to become a global city. Istanbul is enumerated within the first 50 cities in the globalization process, other than the triad of New York, London, and Tokyo. This chapter explores urban space transformation of Maslak, the contemporary central business district of Istanbul, with respect to information and communication technologies, by using deconcentration and economic restructuring approaches of urban theory. Compared to other global cities, Istanbul has distinctive characteristics, since it has been passing through a unique transformation process. More specifically, its economic, political, and social characteristics distinguish Istanbul from other cities within the same category (Gamma) of world cities. This study has revealed that transformations in Istanbul were not primarily driven by information and communication technologies. In contrast information and communication technology's role in the transformation of the Istanbul central business district is only a contributing factor.Book Part Citation - Scopus: 7Understanding the Supply Side: Ict Experience of Marmara Region, Turkey(Information Science Reference, 2008) Velibeyoğlu, Koray; Yiğitcanlar, TanMarmara region's local governments in Turkey are setting the benchmark for the country in the implementation of spatial information systems and e-governance. The chapter aims to shed light on organizational realities of recent practices of information systems and technologies based on the evidences from selected local government organizations in the Marmara region. This chapter scrutinizes these practices and discusses the pivotal relationship between the information and communication technologies and its local organizational context within the region. The chapter also exemplifies challenges and opportunities of the Marmara as an emerging information and communication technology-supported region by illustrating the specific information and communication technology supply instruments. The chapter reveals that the particular success in supply side does not guarantee the sustainable information and communication technology implementation. There are other concerns including demand side that are strongly linked to a realistic understanding of end user demand, the institutional capacity of respected organizations, public-private partnership, and the joined-up policy efforts at both national and local levels.
