Pan-European Corridor X Development: Case of Literal Implementation of the European Transport Strategy Itself or of Change of the General Environment in the Region?

AbstractIn this paper the implementation of the European Transport Strategy in the case of Corridor X during the last decade is presented. Data and information collected on all the projects along the Corridor and the effective investments realized during the last decade are presented, so that sound conclusions can be formulated concerning the conditions, under which the projects were promoted for implementation, taking also into account strategies, policies, negotiations, initiatives and activities that affected the development of the specific Corridor

Evaluation of a High Occupancy Vehicle Lane in Central Business District Thessaloniki

AbstractTravel Demand Management (TDM) measures, whose primary objective is to alleviate the impacts of traffic and congestion in the urban environment, are nowadays increasingly used to address complex transportation and mobility puzzles. One of the most representative TDM measures is the High Occupancy Vehicles (HOV) lane. This paper presents and discusses the results of the hypothetical implementation of an HOV lane in the CBD area of Thessaloniki, Greece. The impact evaluation was conducted through traffic simulation modeling techniques and the results are expressed in terms of environmental and traffic indicators. The environmental and energy aspects of the examined HOV lane are the focus of attention of the current study, in an effort to assess their contribution to rising sustainability issues. The HOV lane in Thessaloniki's case study proved to be, in principal, an efficient tool for managing transport demand. Nevertheless, there is a need for further examination of the impacts on the whole network

The use of a transport simulation system (AIMSUN) to determine the environmental effects of pedestrianization and traffic management in the center of Thessaloniki

Traffic congestion in urban areas results in increased energy consumption and vehicle emissions. Traffic management that alleviates traffic congestion also mitigates the environmental effects of vehicular traffic. This study uses the transport simulation model AIMSUN to evaluate the environmental effect of a set of traffic management and pedestrianization schemes. The effects of the pedestrianization of specific sections of roads, converting two-way roads into one-way roads for traffic and changing the direction of flow of traffic along one-way roads were simulated for different areas of Thessaloniki’s city centre network. The assessment of the environmental effect was done by determining the predicted fuel consumption and emissions of greenhouse gases (GHG) and air pollutants. Fuel consumption and the environmental indicators were quantified directly using the fuel consumption and emissions model in AIMSUN. A typical weekday morning peak period, between 09:00am–10:00am, was simulated and the demand data obtained using a macroscopic traffic assignment model previously developed for the wider area of Thessaloniki. The results presented in this paper are for network-wide simulation statistics (i.e. fuel consumed, carbon dioxide (CO2), nitrogen oxides (NOx) and particulate matter (PM))

Financing urban transportation infrastructure in a multi-actors environment: the role of value capture

Abstract Purpose A family of innovative financial mechanisms and tools for urban public transport, based on the value increment caused by enhanced accessibility, are lately gaining much popularity as a solution to the challenges posed by public financial resources’ shrinkage: Value Capture Finance (VCF). The effectiveness of applied transport financing policies depends significantly on the level of agreement among stakeholders, making collaboration a prerequisite for success. The research presented herein assesses alternative financing options for urban public transportation which are based on the VCF concept. Method The Multi - Actor Multi-Criteria Analysis (MAMCA) developed by Macharis [1] is used. The methodology is unique in its field, as it includes in-depth involvement of all relevant stakeholders and reveals their way of thinking. Results The proposed methodological framework is applied to the real-world case study of the under construction metro system of Thessaloniki, Greece. Three different financing scenarios are tested, and the criteria weight elicitation is performed through personal interviews with 70 stakeholders belonging to six different groups, namely: Government/Local Authorities, Transport Authorities, Universities/Research Institutions, Private Sector, Society and Professional Associations. Noteworthy similarities but also contradictions among stakeholder groups emerged, highlighted by the different criteria used for each group. Conclusion The paper introduces the MAMCA as an ex - ante evaluation method for different VCF mechanisms for urban transportation infrastructure. MAMCA emerges as a robust methodology for this assessment, as it is proved to be capable of dealing with the VCF complexity and multidisciplinary nature
