Article Citation - WoS: 2Citation - Scopus: 3Can Tube Tunnel Crossings Relieve Urban Congestion Problems? Izmir Tube Tunnel Project Proposal Under Scrutiny(MDPI Multidisciplinary Digital Publishing Institute, 2019) Duvarcı, Yavuz; Yiğitcanlar, TanBuilding underwater tube tunnel crossings to ease the urban congestion problems has become a popular approach for many cities across the globe. London, New York, Istanbul, Hamburg, Sydney and Brisbane are among these cities. However, the effectiveness and externalities of these expensive mega urban infrastructures have also been questioned widely among urban, transport and environmental planning scholars. Given the international popularity of the topic, this study places a new tube tunnel crossings project from Izmir, Turkey under the microscope. In this heuristic simulation study, policy-on scenarios were tested to determine possible impacts of the underwater tube tunnel-crossing project. The traffic impacts are discussed using simulations assigning the initial origin-destination data. The results of the study revealed that, given the two locations, outer and inner locations over the dagger-shape bay, the capacity increments on the bridge links and the links around the periphery highway did not bring any effective solutions beyond some minor improvements. The findings disclosed that the ineffectiveness of the tube tunnel crossing might be due to the excessive congestion happening all over the downtown area, which clogs the passageways to the bridge. The paper highlights the limitations of the tube tunnel-crossing project, emphasises the need for comprehensive investigations before committing to the project and advocates the emphasis to be actually given for sustainable mobility.Article Citation - WoS: 17Citation - Scopus: 21An Evaluation Methodology for the Tangible and Intangible Assets of City-Regions: the 6k1c Framework(Inderscience Enterprises Ltd., 2010) Velibeyoğlu, Koray; Yiğitcanlar, TanTogether with hard and soft networks, tangible and intangible regional assets play an important role in the knowledge-based development of competing city-regions. The aim of this paper, therefore, is to investigate the best ways of managing invaluable tangible and intangible assets of city-regions. The paper explores the importance of asset management of city-regions by giving special emphasis on their knowledge asset base. This paper develops and introduces a theoretical framework to conceptualise a new approach to articulate the strategic planning mechanism, so called the 6K1C framework. The 6K1C framework is part of the strategic planning process of continuous improvement of overall public sector performance. The framework provides a proactive check-list approach integrated for managing and harnessing tangible and intangible assets of the post-industrial city-regions.Conference Object Citation - Scopus: 1A Framework for Integrating Disadvantaged Analysis Into Transportation Planning Models(Gold Coast, 2006) Yiğitcanlar, Tan; Duvarcı, YavuzThe 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).Article Citation - WoS: 23Citation - Scopus: 23Transportation Disadvantage Impedance Indexing: a Methodological Approach To Reduce Policy Shortcomings(Elsevier Ltd., 2015) Duvarcı, Yavuz; Yiğitcanlar, Tan; Mizokami, ShoshiAccess to transport systems and the connection to such systems provided to essential economic and social activities are critical to determine households' transportation disadvantage levels. In spite of the developments in better identifying transportation disadvantaged groups, the lack of effective policies resulted in the continuum of the issue as a significant problem. This paper undertakes a pilot case investigation as test bed for a new approach developed to reduce transportation policy shortcomings. The approach, 'disadvantage-impedance index', aims to ease transportation disadvantages by employing representative parameters to measure the differences between policy alternatives run in a simulation environment. Implemented in the Japanese town of Arao, the index uses trip-making behaviour and resident stated preference data. The results of the index reveal that even a slight improvement in accessibility and travel quality indicators makes a significant difference in easing disadvantages. The index, integrated into a four-step model, proves to be highly robust and useful in terms of quick diagnosis in capturing effective actions, and developing potentially efficient policies.Article Citation - WoS: 9Citation - Scopus: 11Variant Concept of Transportation-Disadvantaged: Evidence From Aydın, Turkey, and Yamaga, Japan(American Society of Civil Engineers (ASCE), 2011) Duvarcı, Yavuz; Yiğitcanlar, Tan; Alver, Yalçın; Mizokami, ShoshiTransportation-disadvantaged groups have been defined in previous studies as those who are low income earners, are family dependent, have limited access to private motor vehicles and public transport services, and are obliged to spend relatively more time and money on their trips. Additionally the disabled, young, and elderly are commonly considered to be among the transportation-disadvantaged. Although generally this definition seems correct, it is not specific enough to become a universal definition that could apply to all urban contexts. This paper investigates whether perceptions of travel difficulty vary as does the definition of transportation-disadvantaged in socioculturally different urban contexts. For this investigation, the writers undertake a series of statistical analyses in a case study of Yamaga, Japan, and compare the findings with a previous case study, in which the same methodology, hypothesis, and assumptions were applied to a culturally and demographically different settlement in Aydin, Turkey. After comparing the findings observed in Aydin with the statistical analysis results in Yamaga, this paper reveals that there can be no detailed, universal definition of the transportation-disadvantaged. The writers conclude that the characteristics of the transportation-disadvantaged are not globally identical, and policies and solutions that work in one locality may not have the same results in another sociocultural context.Article Citation - Scopus: 217Rising Knowledge Cities: the Role of Urban Knowledge Precincts(Emerald Group Publishing Ltd., 2008) Yiğitcanlar, Tan; Velibeyoğlu, Koray; Martinez-Fernandez, CristinaPurpose - The paper seeks to investigate the changing and challenging spatial nature of the rising knowledge cities' knowledge precincts.

The chapter aims to shed light on organizational realities of recent practices of information systems and technologies based on the evidences from selected local government organizations in the Marmara region. This chapter scrutinizes these practices and discusses the pivotal relationship between the information and communication technologies and its local organizational context within the region. The chapter also exemplifies challenges and opportunities of the Marmara as an emerging information and communication technology-supported region by illustrating the specific information and communication technology supply instruments. The chapter reveals that the particular success in supply side does not guarantee the sustainable information and communication technology implementation. There are other concerns including demand side that are strongly linked to a realistic understanding of end user demand, the institutional capacity of respected organizations, public-private partnership, and the joined-up policy efforts at both national and local levels.Book Part Citation - Scopus: 5Online Participatory Decision Support Tools for Knowledge-Based Urban Development(Information Science Reference, 2008) Yiğitcanlar, Tan; Saygın, Mustafa Ömür; Han, Jung HoonParticularly in the last decade, there have been a number of efforts to develop and then integrate planning support systems into existing geographic information systems. This integration brought a new technology called WebGIS, which enables geographic information systems functionalities through the Internet for decision support. No doubt there is a growing demand as more and more individuals want to use online government services to express their views and most importantly to take part in decisionmaking processes interactively. At this point, WebGIS offers a challenging opportunity for online participatory planning since the public could easily access alternative plans and the existing information in geographic information systems databases. This technology enables individuals to be able to take part in plan-making processes and contribute. This chapter explores how these new technological advances could achieve truly transparent plan-making process based on online participatory planning support tools that knowledge-based urban development could benefit from.Book Part Citation - Scopus: 29Queensland's Smart State Initiative: a Successful Knowledge Based Urban Development Strategy?(Information Science Reference, 2008) Yiğitcanlar, Tan; Velibeyoğlu, KorayDuring the last two decades, knowledge-based development has become an important mechanism for knowledge economies. In a knowledge economy, information and communication technology is extensively seen as a potentially beneficial set of instruments, which may improve the welfare and competitiveness of nations and cities. At present, both public and private actors aim to exploit the expected benefits of information and communication technology developments. These technologies offer unprecedented promise for social and economic development on all global, national, regional, urban, and local levels. Therefore, this chapter seeks to investigate the potential of information and communication technology policy at both regional and urban levels, and, in particular, to shed light on various factors that influence urban information technology policies in the public domain. The chapter sets out to explain the knowledge-based urban development processes and challenges and opportunities in information acceptance and use in urban policy-making in Queensland, Australia. This chapter draws on providing a clear understanding on policy frameworks and relevant technology applications of the Queensland Smart State experience.Article Citation - WoS: 72Citation - Scopus: 101Knowledge-Based Urban Development: the Local Economic Development Path of Brisbane, Australia(SAGE Publications Inc., 2008) Yiğitcanlar, Tan; Velibeyoğlu, KorayKnowledge-based development strategies play an important role in supporting local economic development of cities in the knowledge era.
