Introduction
This paper introduces an innovative method to reduce car accidents by employing mechanical concepts and energy conservation to model drivers’ reactions in unexpected scenarios.
Methodology
The approach involves formulating equations to define drivers’ “internal stress energy,” indicative of their propensity for aggressive driving unde...
Mountainous regions often present formidable barrier to traditional transportation system, limiting access and impending economic growth. In this regard, a new technology called CASWAT-G (Circulating Cable Supported Up-down Walking Technology by Using Gravity) surface ropeway (CSR) is one that uses simple parts and eases up-down walking because of...

This paper aims to investigate and evaluate the characteristics of the pedestrian environment in the two cities and to draw conclusions regarding the elements that encourage walking i...
The road freight transport sector in Greece, a once-thriving industry of the Greek economy, currently faces many threatening challenges. In this paper, we conducted a literature review and a series of four in-depth interviews with stakeholders of the sector in order to identify the main problems that the industry currently faces and to find and pro...
In the Regional Unit of Thessaloniki, severe traffic problems are observed during peak hours and especially in its urban center. It is also observed that the occupancy of the cars that serve the demand is rather low, i.e., 1.44 travelers per vehicle. This phenomenon, combined with the unattractiveness of public transport, exacerbates the Unit’s tra...
Sidewalks are an integral part of everyday human mobility habits. Although more interest is growing in the design of more eco-friendly and human-friendly sidewalks, the infrastructure in Greece is still problematic as far as environmental and accessibility factors are concerned. This paper attempts to determine the most important factors for the in...

Decisions on when to replace a piece of equipment are characterized by many...
CASWAT-G (Circulating Cable Supported up down Walking Technology by Using Gravity) is a gravity and leg muscle force operated surface ropeway that works as a gravitational force harvesting transportation system. Both sides’ users are connected to a Circulating Cable (CC), and when they are supported by it, gravity balance is created through harvest...
The original core concept of sustainable mobility is based on shifting travelers from private and motorized vehicles to other soft and more eco-friendly modes of mobility. The fulfillment of this aim indicates the importance of the human factor in terms of knowledge, awareness, perceptions, attitudes, intentions, and behavior. Citizens’ Panels, com...
This paper aims to explore the potential of carsharing in Greece and to estimate its level of acceptance by the Greeks. The growth of carsharing services as a new and more sustainable way of transport is shifting mobility from private ownership to shared use. Cities and the lives of people are transformed by the sharing economy and collaborative co...
The regions of the European Union (EU) countries could play a significant role in implementing European and national policies towards the enhancement of innovation and competitiveness of the transport-related ecosystem of key stakeholders and actors. Regional policies may cover a wide spectrum of fields, such as investments in enhancing main innova...
Sustainable mobility is the ability to meet society’s need to move freely, communicate, gain access, trade, and establish relationships without sacrificing other essential human or ecological values, today or in the future. Sustainable mobility includes both the transportation of goods and people. Sustainability, when applied to urban mobility, can...
The purpose of this paper is to examine the new reality that is formed through the gradual transition from car-ownership to carsharing and carpooling. In this new reality, car use is gradually detached from its ownership, and there are challenges and prospects that have to be examined in order to become opportunities. Everyone will be able to use a...

Public Transport (PT) is a key factor towards sustainable urban mobility. The increase of its modal share requires the continuous adoption of new innovative and user-centric solutions covering the existing and emerging needs of citizens. Which concepts and ideas should be promoted and financed by priority? The paper aims to present the quantitative...
Flexible Transport Services (FTSs) are usually recommended as an appropriate solution for the service of travel needs of low demand areas and/or vulnerable people. The flexibility in terms of their design characteristics (e.g. booking procedure, pricing, Level of Service [LoS], etc.) raises the problem of their determination (levels) towards the cr...
Not all of the travel needs are adequately covered by the existing commercially oriented Public Transport (PT) services, while public funding is gradually being reduced. At the same time, disruptive global societal and market trends create new social challenges at local level. By activating the catalyst group of social entrepreneurs, new innovative...

In 2000, road accidents killed over 40,000 people in the European Union (EU) and injured more
than 1.7 million. The age group most affected is the 14 – 25 year olds, for whom road accidents
are the prime cause of death (European Commission (EC), 2001, p. 66).
Research suggests that at the system of road safety the human factor is a sole or a contri...
