Regeneration, revitalization, and/or heritage conservation are not properly managed due to problems arising directly from inconvenient transport solutions that cannot provide or resolve the accessibility and mobility needs of vulnerable groups together with inappropriate space management while indirectly causing economic shrinkage and loss of vitality. Furthermore, even if modern modes of transportation are used, they will cause significant environmental and societal difficulties, making them unsuitable for such sensitive places. This article, using a microsimulation approach, investigates whether a Personal Rapid Transit system is physically applicable, and whether it can meet existing travel requirements to prove that it is sufficient for the needs of local level mobility, and finally whether other environmental/ social impacts such that land use, air pollution, safety, sustainability are positive or negative. As a method, these outputs of the system application are presented as validations of the usefulness of the PRT. Finally, it was found that there is a gain in productivity in terms of mobility as well as other socioeconomic benefits besides the physical applicability of the method. The study's goal is to get the information out about how PRT technology may help produce more ecologically friendly and sustainable solutions while also conserving historical assets.

The findings were observable at all stages of the sequential modeling; however, with slight differences compared to 'normal' model results. This paper aims to show that the method of policy capture could be possible based on these differences, and could help improve the adverse conditions of the disadvantaged. The analysis method, a category analysis based on cluster analysis results, used TRANUS software to run simulations for the 3 disadvantaged types: socioeconomic, spatial, and positional. Simulation results demonstrate that the socioeconomic dimension was the best for policy capture.

The first question is how much heat energy the geothermal resource contains? The second one is what the utilization alternatives are for this resource? And the last question is according to which criteria the scenarios formed by integration of the selected utilization alternatives in specified proportions could be assessed, and what the alternative schema obtained could be like? The method of forming a model by simulations, which is developed as an approach to the solutions of the problems that contain uncertain parameters, like what the heating capacities of the reservoirs are, is used in this study. A model is formed with parameters of the heating capacity of Balçova Geothermal Field by employing Monte Carlo Simulation Technique. Here the aim is to find the amount of the heating energy that

The major reason is probably that the qualitative and social parameters that could be the real factors in the explanation of the "disadvantagedness" have not been efficiently considered in the modelling because of the uncertainty, and non-normative nature of the models.This thesis study as a normative one offers basically two methodological approach that can be integrated to the normal models: First, the clear-cut defInition of so-called disadvantaged by the cluster analysis method, and second, application of the modelling procedures both for normal case and for the disadvantaged simulatenously by which the determination of policy packages (policy capturing) is probable on the basis ofthe differences between the two models. The improvement of disadvantaged means getting closer to the normality in transportation conditions. With this, it is meant that policy-making to improve the disadvantaged can even start from the modelling stages.As an innovative approach, vanous correlated variables are grouped into "Major" variables in the form of function formulations, which are thought best represent the social/qualitative parameters.In the model runs, latest version of TRANUS (6.0) was used to speed up the modelling process (especially the Trip Assignments). With TRANUS., categorical handling is possible. It is found that there appears a remarkable discrepancy between the two models at the level of Trip Generations (productions), and some different variables could be used in the model for disadvantaged.Finally, in the Correspondence Module (or, category analysis), as of the adopted equity principles, the association of those disadvantaged categories (as transportation categories) with the "disadvantagedness" levels is maintained. This matching process also provided a gauge with which the policies could be produced for the matching transportation (disadvantaged) categories. To see the effectiveness of the method, three simulations are run based on the three policy scenarios where any move towards betterment in the condition of disadvantaged is welcome.As the result of this study, though less than expected, an improvement was observed in the travel conditions of the disadvantaged.

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

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.The effects of major transportation projects on the urban trends in İzmir were analyzed using the Delphi method. Once the convergence was maintained in the expert opinions, the Delphi results were re-evaluated according to suggested method of total evaluation for obtaining much concise and general results. Accordingly, Absolute Total Impacts (MED), Net Total Impacts (NED) 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’s Port. The most impacted trends were: Development in Tourism Sector, Economic Development, Air Pollution and the Rate of Private Car Ownership

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.
