    İzmir’deki Ulaştırma Projelerinin Kentsel Eğilimlere Etkileri
    (TMMOB İnşaat Mühendisleri Odası, 2008) Duvarcı, Yavuz; Selvi, Ömer; Günaydın, Hüsnü Murat; Gür, Güneş
    İzmir’deki önemli ulaştırma projelerinin kentsel eğilimlere olan etkileri Delphi yöntemi sonuçları temel alınarak analiz edilmiştir. Delphi yöntemine göre yakınsama sağlanmış etkiler, sonrasında daha anlamlı ve özet sonuçlar elde etmek amacıyla toplamdaki etkiler yöntemiyle yeniden değerlendirilmiştir. Yönteme göre, mutlak toplam etkilere (MED), net toplam etkilere (NED) ve en genel anlamda etki yeterlik düzeylerine bakılarak genel sonuçlara ulaşılmıştır. En etkili (olumlu/olumsuz yönde) projeler, bütünleştirilmiş raylı toplu taşıma sistemi, mevcut İzmir limanının geliştirilmesi; en fazla etkilenen sosyoekonomik eğilimler ise turizm sektöründeki gelişim, ekonomik gelişme, hava kirliliği ve özel araç kullanım oranı olarak çıkmıştır.

    Making Accident Data Compatible With Its-Based Traffic Management: Turkish Case
    (Intelligent Transport Systems, 2010) Duvarcı, Yavuz; Geçer Sargın, Feral; Kumova, Bora İsmail; Çınar, Ali Kemal; Selvi, Ömer
    One of the most important reasons of the high rate of accidents would largely lend itself to ineffective data collection and evaluation process since the necessary information cannot be obtained effectively from the traffic accidents reports (TAR). The discord and dealing with non-relevant data may appear at four levels: (1) Country and Cultural, (2) Institutional and organizational, (3) Data collection, (4) Data analysis and Evaluation. The case findings are consistent with this knowledge put forward in the literature; there is a transparency problem in coordination between the institutions as well as the inefficient TAR data, which is open to manipulation; the problem of under-reporting and inappropriate data storage prevails before the false statistical evaluation methods. The old-fashioned data management structure causes incompatibility with the novel technologies, avoiding timely interventions in reducing accidents and alleviating the fatalities. Transmission of the data to the interest agencies for evaluation and effective operation of the ITS-based systems should be considered. The problem areas were explored through diagnoses at institutional, data collection, and evaluation steps and the solutions were determined accordingly for the case city of Izmir.

    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).

    Contribution 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, Figen
    Though 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.

    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.
