Rail traction and resistance play an essential role in the efficient operation of rail systems. The nature of traction is based on the balance between static friction and generated force at the perimeter of the driving wheels. The main objective of this paper is the development of a methodology and a modeling procedure for the design of train speed...
The main objective of this work is to present a comprehensive and integrated methodology to enhance the resilience of transportation critical infrastructure (TCI), focusing on the interplay between geotechnical assets and the transport network. Societies are greatly dependent on transport infrastructure systems, and as the mobility of passengers an...
In its first part, the paper gives a summary of the levels of emissions resulting from each mode of transport by use of statistics at the European and global levels. It also summarizes the main measures and policies that have been put forward for the reduction of freight transport greenhouse gas (GHG) emissions. To facilitate the subsequent analyse...
The current paper presents the results of a study that analyzed and evaluated the efficiency of the largest container ports in the wider area of the Mediterranean Basin. The research question that this paper seeks to respond to is how the resources (inputs) of a container port reflect its level of activity and efficiency. In particular, what is the...
This paper expands a methodology, originally formulated for calculating the firm-level business value of Information Technology (IT), to that for a whole sector and applies it experimentally for the transport sector using statistical databases for several countries in Europe. The term “business value” means the quantified impact of a given technolo...
Transportation infrastructures provide essential functions and services that support European Societal, Economic and Technological (SET) environments and are commonly designed, built and maintained according to rigorous standards. As their exposure to extreme hazards becomes frequent, it is vital to ensure their capability of withstanding, adapting...
This paper examines the objectives and the main elements of a national energy policy for transport based on the experience of such plans in the six Mediterranean EU-member countries. These plans define the energy and Green House Gas emission reduction objectives in the field of Transport which are adopted by each country and provide a guideline for...
For the majority of EU member countries, but especially those of the South i.e., Greece, Italy, Spain and Portugal, the last decade was characterised by a period of negative economic growth and general instability of their economies. During that period, the four countries faced significant changes to the output of several economic sectors, a develo...
During the last years, gasoline consumption, mainly for road transport, has dropped by more than 30% in Greece, while diesel consumption has seen a generally upward trend after 2013. In contrary, consumption of alternative fuels follows a positive trend. However, in 2016, the national use of Renewable Energy Sources in transport was at 1.4%, though...
freight transportation analysis. Reliable and sufficient data enable the detailed analysis for future planning, for both, infrastructure and operation of transport network. Although the significance of transport data is widely acknowledged by researchers and policy decision-makers, several issues still exist, limiting the proper collection but abov...
The current work focuses on the islands of the South Aegean and attempts to highlight the
importance of airport infrastructure for their tourism development. The impact of other island
characteristics (area, shore length, population, number of beds in various classes of
accommodation, cost of accommodation, island’s attractiveness, distance from Pi...
The transport sector is closely related to the economy of a country. This mainly applies to urban areas, which play an essential economic role in a country’s GDP. According to the EC’s Green Paper 2007 for urban mobility, approximately 1% of the EU’s GDP is annually lost due to the increased passenger and freight flow demands in city centres and it...
Natural gas is an environmental friendly energy source used in various residential and industrial applications. Gas energy security is high in the agenda of Europe asking for the systematic investigation of all pertinent factors. To this aim a gas network model was developed for testing demand and supply scenarios. Demand scenarios assume that alth...
Urban areas have an essential economic role in a country’s GDP. According to the EC’s Green Paper 2007 for urban mobility, approximately 1% of the EU’s GDP is annually lost due to the increased passenger and freight flow demands in city centres and its consequent impacts (e.g. pollution, delay etc.). On this basis, the primary goal of this paper is...
During the last eight years, Europe, and the world as general, has been experiencing a situation of sudden economic recession resulted in economic and financial crisis. According to the IMF (2009), this is the worst recession of the last decades since economies, countries and global GDP have been seriously affected. A sector of the economy that has...
The main purpose of this paper is to present the results of a comprehensive research study that took place in Greece in order to investigate the process and the criteria for freight modal choice behavior. It involved a large scale survey among various “actors” in the freight transport scene in Greece, and a full scale analysis of the results and ou...
The process and criteria for freight modal choice behavior in Greece were investigated in research between 2004 and 2009. The work involved a large-scale survey of various freight transport actors in Greece; a full statistical analysis of the results and a presentation to determine priorities, preferences, and detailed rankings of mode choice crite...

The expansion of the urban railway in the city of Athens with two new Metro lines required the upgrading of the existing infrastructure in order to comply with the new modern lines in terms of capacity and quality of service. This paper presents a simulation-based modelling tool that was developed and used for the purposes of the relevant capacity...
