Article Citation - Scopus: 2Impact of High Speed Railway Systems on Inter-Regional Trips and Accessibility in Turkey(Istanbul Teknik Universitesi, Faculty of Architecture itudergisi@itu.edu.tr, 2020) Baş, Ahmet; Yüzer, Mehmet AliHigh-speed trains are faster, safer, more comfortable than road transport for trips of 250–1000 kilometers. Accordingly, a significant increase has been observed in inter-city railway transport following the construction of high-speed railway (HSR) connections. The present study shows the effects of HSR on accessibility and potential savings in time when compared to other transportation modes. The time saved by HSR systems has been shown to change purpose trip. The level of accessibility provided by the HSR between Konya–Ankara–Istanbul link is compared with the accessibility of other travel modes through an investigation of the weighted average travel times and an analysis of costs. Furthermore, data gathered from a field study carried out among users of the Konya-Ankara HSR link is used to identify the distribution of travel choices among different transportation modes, based on such social and economic indicators as income, car ownership and employment status. It is found that HSR service increases accessibility between cities, and changes travel demands and purpose, in favor of railways, and that economic factors such as income and car ownership are important in the use of HSR services. Finally, this research identifies social and cultural activities as a new reason for travel, in which users diversify their travel destinations because of the time savings offered by HSR systems. © 2020 Elsevier B.V., All rights reserved.Article Citation - Scopus: 1A Conceptual Process Model for the Sustainability of a Healthy Building(Istanbul Teknik Universitesi, Faculty of Architecture itudergisi@itu.edu.tr, 2016) Sarp Yalçin, Asutan; Balanlı, Ayşe; Yalçın, Asutan SarpHealthy buildings may lose their healthy characteristics over time and due to changing circumstances during their usage phase, which may lead to biological and psychological health problems for their users. Thus a process model is required for buildings which ensures that the initial healthy environment is retained. This study therefore introduces a conceptual Process Model for the Sustainability of a Healthy Building. In the study, the sustainability of the healthy building and its criteria were determined by the help of the definition of sustainability and associated criteria. Then, the changes which prevent the building from sustaining its healthy status were introduced. Based on the events that lead to the loss of healthy building performance, the actions and functioning of the process model were created. Action steps were then composed and the relationship between these steps were established. As a result, the principal components of this model are determined as Achievement of a Healthy Building, Sustainability Assessment of a Healthy Building, and Sustainability Management of a Healthy Building. Application of the procedures in the proposed model can help maintain the healthy characteristics of buildings throughout their operational lifespan, thereby preserving the basic requirement for a healthy environment. © 2020 Elsevier B.V., All rights reserved.
