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: 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. This paper investigates local knowledge-based urban development policies of Brisbane, Australia in its long journey to become a competitive knowledge city. The paper examines Brisbane's recent progress towards establishing knowledge community precincts that are critical creative urban environments to attract and retain global investment and talent. This paper also discusses major challenges Brisbane is experiencing during the implementation of its state- and city-wide knowledge-based urban development strategies.
