The term physical accessibility has long been used by geographers, economists, and urban planners and reflects the relative ease of access to/from several urban/rural services by considering the traveling costs. Numerous accessibility measures, ranging from simple to sophisticated, can be observed in the geographical information systems (GIS)-based accessibility modeling literature. However, these measures are generally calculated from a constant catchment boundary (a most likely or average catchment boundary) based on constant deterministic transportation costs. This is one of the fundamental shortcomings of the current GIS-based accessibility modeling and creates uncertainty about the accuracy and reliability of the accessibility measures, especially when highly variable speeds in road segments are considered. The development of a new stochastic approach by using global positioning system (GPS)-based floating car data and Monte Carlo simulation (MCS) technique could enable handling the variations in transportation costs in a probabilistic manner and help to consider all possible catchment boundaries, instead of one average catchment boundary, in accessibility modeling process. Therefore, this article proposes a stochastic methodology for GIS-based accessibility modeling by using GPS-based floating car data and MCS technique. The proposed methodology is illustrated with a case study on medical emergency service accessibility in Eskisehir, Turkey. Moreover, deterministic and stochastic accessibility models are compared to demonstrate the differences between the models. The proposed model could provide better decision support for the decision-makers who are supposed to deal with accessibility, location/allocation, and service/catchment area related issues.

GIS-based stochastic modeling of physical accessibility by using floating car data and monte Carlo Simulations Ertuğay, Kıvanç; Düzgün, H. Şebnem; Department of Geodetic and Geographical Information Technologies (2011) The term physical accessibility has widely been used by geographers, economists and urban planners and basically reflects the relative ease of access to/from several urban/rural services by considering various travelling costs. Numerous accessibility measures, ranging from simple to sophisticated, can be found in the GIS based accessibility modeling literature. However, whether simple or sophisticated, one of the fundamental shortcomings of the current GIS-based accessibility measures is that they are gener...
Object-based classification of landforms based on their local geometry and geomorphometric context GERÇEK, DENİZ; Toprak, Vedat; Strobl, Josef (Informa UK Limited, 2011-01-01) Terrain as a continuum can be categorized into landform units that exhibit common physical and morphological characteristics of land surface which may serve as a boundary condition for a wide range of application domains. However, heterogeneous views, definitions, and applications on landforms yield incompatible nomenclature that lacks interoperability. Yet, there is still room for developing methods for classification of land surface into landforms that can provide different disciplines with a basis of lan...
Exploring the relationship between web presence and web usability for universities A case study from Turkey Peker, Serhat; Kucukozer-Cavdar, Seyma; Çağıltay, Kürşat (Emerald, 2016-01-01) Purpose - The purpose of this paper is to statistically explore the relationship between web usability and web presence of the universities. As a case study, five Turkish universities in different rankings which were selected from Webometrics rankings were evaluated and compared.
Spatial organization of service activities in ankara Levent, Tolga; Günay, Baykan; Department of City and Regional Planning (2007) In the last decades, the spatial organization of services has become a key issue in the urban planning literature. The basic reasons for this significance are the difficulties not only in understanding this complex and context-dependent organization, but also in developing planning interventions for this organization. Moreover, author believes that the existing theoretical frameworks have some inabilities in interpreting the spatial organization at the intra-metropolitan scale. Therefore, this study basical...
Geographical information systems based microzonation map of Eskişehir downtown area Kolat, Çağıl; Doyuran, Vedat; Department of Geological Engineering (2004) The purpose of this study is to prepare a geotechnical microzonation map regarding the suitability of the residential areas in Eskisehir downtown area. In order to obtain the microzonation map, Geographical Information Systems (GIS) based Multicriteria Decision Analysis (MCDA) is used. For this analysis, the slope, flood susceptibility, soil, depth to groundwater table, swelling potential and liquefaction potential layers are prepared. The weight values to the layers and rank values to the classes of each l...
