    Determining Scenario Based Highway Routes Using Geographic Information Systems; a Case Study of Simav-Kutahya Routes, Turkey
    (Pamukkale Üniversitesi, 2014) Erdem, Umut
    Transportation planning requires more efforts from city planners to use rational techniques to determine optimum road routes. To fulfill this requirement, this study aims at generating the cheapest and the shortest scenario based routes using Geographic Information Systems (GIS) and Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Digital Elevation Model (DEM) with Least Cost Path analysis between the Simav and the Kutahya cities, and comparing them with existing routes. For generating the shortest and the cheapest route, these cities are selected as sample since the study region is located in the transition area between central Anatolia and Aegean Region which has access to the sea and regional ports. The methodology used in this study is composed of three parts: first part consists of two steps; (i) generating the factors and (ii) determining scenarios focusing on different transportation themes that are used in the study process. In second part all factors are weighed regarding scenarios. In the third part of the study the outputs Path A (cheapest) and Path B (shortest) are generated by Least Cost Path analysis. The output routes were compared not only with each other, but also with the existing routes in terms of the generated factors.

    A Framework for Integrating Disadvantaged Analysis Into Transportation Planning Models
    (Gold Coast, 2006) Yiğitcanlar, Tan; Duvarcı, Yavuz
    The ability to access personal or public transportation is fundamental for people to connect with employment opportunities, health and medical services, educational services, and the community at large. However certain populations lack the ability to provide their own transportation or have difficulty accessing whatever conventional public transportation may be available (Department of Transportation 2003). The ‘transportation disadvantaged’ populations are those persons who are unable to transport themselves or are unable to purchase transportation due to physical or mental disability, income status, or age. Therefore, the transportation disadvantaged are dependent upon others to obtain access to health care, employment, education, shopping, and other life sustaining activities. Additionally, since disadvantage is a personal experience, it can be simply characterised as what people perceive to be transportation disadvantage (Raje 2003).

    Impacts of Transportation Projects on Urban Trends in Izmir
    (Turkish Chamber of Civil Engineers, 2008) Duvarcı, Yavuz; Selvi, Ömer; Günaydın, Hüsnü Murat; Gür, Güneş
    The effects of major transportation projects on urban trends in Izmir were analyzed using the Delphi method. Once convergence was maintained in expert opinions, the Delphi results were re-evaluated according to the suggested method of total evaluation for obtaining much concise and general results. Accordingly, Absolute Total Impacts (ATI), Net Total Impacts (NTI) and the impact levels in broader terms were defined. The most effective projects were found to be: Integrated Rail Transportation System, Enhancement of Existing İzmir Port. The most impacted trends were: Development in Tourism Sector, Economic Development, Air Pollution and the Ratio of Private Car Ownership.
