Congestion Problems

Building 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.

The energy consumption and emissions in the urban transportation are influenced not only by technical efficiency in the mobility operations but also by the citizens’ mobility behaviors including mode choices and modal shift among sustainable and unsustainable mobility modes. Information and Communication Technologies (ICTs) can play an important role in the mobility behaviors of citizens, and it is necessary to study whether ICTs support sustainable mode choices like public transport and nonmotorized modes, which increase the total energy efficiency in the urban mobility and reduce traffic congestion and related emissions. This paper focuses on the two most popular ICT services in the urban transport, which are ATIS (Advanced Traveler Information Systems), and ridesourcing services. This study used the New York Citywide Mobility Survey (CMS) findings with a sample of 3346 participants. The associations between using these two ICT services and the mobility behaviors (mode choice with ATIS and modal shift to ridesourcing) are analyzed through a multinomial logistic regression and descriptive statistics, and the results are compared with similar international studies. The findings indicate that the respondents who use ATIS apps more frequently are more likely to use rail modes, bicycles, bus/shuttles, and rental/car sharing than private cars for their work trips. Moreover, the findings of the modal shift to ridesourcing indicate that the most replaced mobility modes by ridesourcing services are public transport (including rail modes and buses), taxis, and private cars, respectively.

Cycling and general sustainable mobility has become a topical issue around Europe, and gradually also in Latvia, including Valmiera – a medium size town, which is a research-base for this study where the governance and development of the municipal cycling infrastructure is analysed. The rapid growth of cycling in Valmiera not only highlights some deficiencies in urban infrastructure developments, but also reveals the management problems: the expectations and needs of users of different means of transportation and also pedestrians are not met. Looking towards solving various cycling development issues, it is necessary, first of all, to develop an understanding of system’s approach and the systemic governance of the cycling infrastructure. The urban transport/mobility system must be developed as a whole, integrating cycling mobility in it as an independently and continuously developing component, promoting a process of cooperation between all parties involved. Thus, to facilitate the cycling mobility of inhabitants in Valmiera, the involvement/participation of all the interested parties shall be pro-actively communicated – informed, educated/trained, pro-cycling behaviour encouraged. During this integrative case study, both quantitative and qualitative research methods were applied complementary: analysis of documents, infrastructure observations in the town with photo documentation, survey of inhabitants, also in-depth semi-structured interviews with open-ended questions. Additionally, a participatory observation was conducted through participation in cycling activities, forums, working groups, etc., elaborating suggestions for the municipal planning document - Transport Infrastructure Development Concept of Valmiera.

<p>The European Union, its member states and local authorities have been working for long time on the design of solutions for future sustainable mobility. The promotion of a sustainable and affordable urban transport contemplates the bicycle as a mean of transport. The reasons for analysing the cycling mobility in urban areas, has its origin in the confrontation with motorized vehicles, as a sustainable response to the environment. In this context of sustainable mobility, the research team has studied the use of bicycles in Mediterranean cities, specifically in coastal tourist areas.  The present work shows the development of a mobility index oriented to the bicycle, transport that competes with the private vehicle. By means of a survey methodology, the research group proceeded to collect field data and the subsequent analysis of them, for the development of a mobility index adapted to bicycle mobility, and with possibilities to adapt to urban environments.</p>

Multicriteria Decision

An increasing number of recent discussions have focused on the need for designing transport systems in consonance with the importance of the environment, thus promoting investment in the growth of non-motorized transport infrastructure. Under such conditions, the demand for implementing the most effective infrastructure measures has a profoundly positive impact, and requires the least possible financial and human resources. The development of the concept of sustainable mobility puts emphasis on the integrated planning of transport systems, and pays major attention to the expansion of non-motorized and public transport, and different sharing systems, as well as to effective traffic management involving intelligent transport systems. The development of transport infrastructure requires massive investment, and hence the proper use of mobility measures is one of the most important objectives for the rational planning of sustainable transport systems. To achieve this established goal, this article examines a compiled set of mobility measures and identifies the significance of the preferred tools, which involve sustainable mobility experts. The paper also applies multicriteria decision making methods in assessing urban transport systems and their potential in terms of sustainable mobility. Multicriteria decision making methods have been successfully used for assessing the effectiveness of sustainable transport systems, and for comparing them between cities. The proposed universal evaluation model is applied to similar types of cities. The article explores the adaptability of the model by assessing big Lithuanian cities.

This paper presents theoretical comments on the “Taiyuan’s Urban Master Planning (2010-2020)” mainly in the aspects of the city's orientation, functions, urban transportation and eco-environmental planning. It can be seen that the master planning have a new scientific orientation of the city of Taiyuan by perceiving it as “a historic ancient capital of culture"; sufficient attention is paid to the relocation, renovation and update of TISCO, TCIGO and other heavy chemical companies; the newly designed urban public transit passenger transport organization mode is utilized to settle the increasingly prominent urban transport problems; tourism development is promoted under the premise of the protection of ecological environment as well as historical and cultural heritages; a number of shortcomings and recommendations for improvement are also proposed, trying to provide decision-making references for further adjustments and improvements of Taiyuan’s urban planning.
