Article
Full-text available
Sustainable urban mobility has been the epicenter both at the scientific and administrative level during the last decades, with a high number of relevant research projects, awareness campaigns, and other initiatives taking place at the local, national, and international level. However, many urban areas have so far achieved limited results in this d...
Article
Full-text available
After the awareness-raising of recent years for coping with the global societal, economic and environmental challenges, the need for sustainable planning in the transport sector has become even more evident. Initiatives aiming at promoting sustainable and innovative mobility solutions, especially in urban areas where mobility needs are higher and t...
Article
Full-text available
Autonomous vehicles will significantly affect mobility conditions in the future. The changes in mobility conditions are expected to have an impact on urban development and, more specifically, on location choices, land use organisation and infrastructure design. Nowadays, there is not enough data for a real-life assessment of this impact. Experts es...

Territorial Impact Assessment (TIA) is proposed as a critical tool in order to investigate the way policies affect spatial development and hence territorial cohesion. The paper introduces a TIA methodological model in relation to transport sector. The design of the methodological model is based on a quantitative evaluation framework that comprises...
Article
Full-text available
The conventional approach in transport planning aims at the expansion of road transport infrastructure to cope with the increasing transport demand. However, this car-based planning approach not only fails to fulfill the mobility needs due to the limited space available for new road infrastructure leading thus to the vicious circle of traffic conge...
Article
Full-text available
An integrated strategy was recently set out in Europe regarding the internalization of external costs from transport, i.e. the costs from the negative externalities to the society generated by the transport users. These externalities refer to impacts on the rest of transport users, such as delays due to congestion, accidents and scarcity of infrast...
Conference Paper
Full-text available
The constant increase in mobility demand combined with the limited availability of space for the expansion of road infrastructure but also the critical issue of coping with the multiple externalities of private car use has led to a new approach in transport planning, which takes into account the interactions between the transport system and the nat...
Article
Full-text available
Since the late 20th century, academic institutions have conducted extensive research towards the promotion of sustainable mobility in cities and urban areas. However, a lack of an organised framework of policies and measures can be observed when looking at attempts to strengthen sustainability in the transport system of academic campuses, apart fro...
Conference Paper
Full-text available
The provision of environmental friendly public transport solutions is a common policy of cities in Europe in order to reduce the use of the private car and thus contribute to the EU mid-term and long-term goals for energy efficiency, air pollution and climate change resilience. Consistent to these goals, the urban seaborne transport system which is...
