Proceedings of the 3rd International Conference on Models and Technologies for Intelligent Transportation Systems 2013
Challenges arising from an increasing traffic demand, limited resource availability and growing quality expectations of the customers can only be met successfully, if each transport mode is regarded as an intelligent transportation system itself, but also as part of one intelligent transportation system with “intelligent” intramodal and intermodal interfaces. This topic is well reflected in the Third International Conference on “Models and Technologies for Intelligent Transportation Systems” which took place in Dresden 2013 (previous editions: Rome 2009, Leuven 2011). With its variety of traffic management problems that can be solved using similar methods and technologies, but with application specific models, objective functions and constraints the conference stands for an intensive exchange between theory and practice and the presentation of case studies for all transport modes and gives a discussion forum for control engineers, computer scientists, mathematicians and other researchers and practitioners.
The present book comprises fifty short papers accepted for presentation at the Third Edition of the conference. All submissions have undergone intensive reviews by the organisers of the special sessions, the members of the scientific and technical advisory committees and further external experts in the field. Like the conference itself the proceedings are structured in twelve streams: the more model-oriented streams of Road-Bound Public Transport Management, Modelling and Control of Urban Traffic Flow, Railway Traffic Management in four different sessions, Air Traffic Management, Water Traffic and Traffic and Transit Assignment, as well as the technology-oriented streams of Floating Car Data, Localisation Technologies for Intelligent Transportation Systems and Image Processing in Transportation.
With this broad range of topics this book will be of interest to a number of groups: ITS experts in research and industry, students of transport and control engineering, operations research and computer science. The case studies will also be of interest for transport operators and members of traffic administration
2nd Symposium on Management of Future motorway and urban Traffic Systems (MFTS 2018): Booklet of abstracts: Ispra, 11-12 June 2018
The Symposium focuses on future traffic management systems, covering the subjects of traffic control, estimation, and modelling of motorway and urban networks, with particular emphasis on the presence of advanced vehicle communication and automation technologies.
As connectivity and automation are being progressively introduced in our transport and mobility systems, there is indeed a growing need to understand the implications and opportunities for an enhanced traffic management as well as to identify innovative ways and tools to optimise traffic efficiency.
In particular the debate on centralised versus decentralised traffic management in the presence of connected and automated vehicles has started attracting the attention of the research community.
In this context, the Symposium provides a remarkable opportunity to share novel ideas and discuss future research directions.JRC.C.4-Sustainable Transpor

Optimizing multiple truck trips in a cooperative environment through MILP and Game Theory
Today, the challenge of economy regarding freight transport is to generate flows
of goods extremely fast, handling information in short times, optimizing decisions,
and reducing the percentage of vehicles that circulate empty over the total amount
of transportation means, with benefits to roads congestion and the environment,
besides economy. Logistic operators need to pose attention on suitable planning
methods in order to reduce their costs, fuel consumption and emissions, as well as
to gain economy of scale. To ensure the maximum efficacy, planning should be also
based on cooperation between the involved subjects. Collaboration in logistics is
an effective approach for business to obtain a competitive edge. In a successful
collaboration, parties involved from suppliers, customers, and even competitors
perform a coordinated effort to realize the potential benefit of collaboration,
including reduced costs, decreased lead times, and improved asset utilization and
service level. In addition to these benefit, having a broader supply chain perspective
enables firms to make better-informed decisions on strategic issues.
The first aim of the present Thesis is to propose a planning approach based on
mathematical programming techniques to improve the efficiency of road services of
a single carrier combining multiple trips in a port environment (specifically, import,
export and inland trips). In this way, in the same route, more than two transportation
services can be realized with the same vehicle thus significantly reducing the number
of total empty movements. Time windows constraints related to companies and
terminal opening hours as well as to ship departures are considered in the problem
formulation. Moreover, driving hours restrictions and trips deadlines are taken into
account, together with goods compatibility for matching different trips.
The second goal of the Thesis is to define innovative planning methods and
optimization schemes of logistic networks in which several carriers are present and
the decisional actors operate in a cooperative scenario in which they share a portion
of their demand. The proposed approaches are characterized by the adoption both of
Game Theory methods and of new original methods of profits distribution

Balancing Spatial and Environmental Impacts of large scale Renewable Offshore Energy Generation in the North Sea
The growing EU energy ambitions in the North Sea region are urging for an accelerated deployment of large-scale renewable energy (RE) infrastructure, with offshore wind farms (OWF) playing an essential role. However, implementing the current EU targets can be limited by the multiple competing spatial claims between existing sea uses, ecological values and OWFs, causing key uncertainties related to potential risks of interaction that may result in barriers to a swift roll-out of RE infrastructure. Up to this date there is no clear understanding of the space availability for different renewable energy installations. Such space availability depends on the alternative space management options applied, relying e.g. on more sectoral management to separate activities or instead, more integrated management to pursue multiuse in time or space. Understanding these trade-offs is especially urgent in the current context of planning marine resources on the North Sea, characterized by lack of coordination, sectoral and fragmented planning, which exacerbates the uncertainties on the potential socio-economic and ecological risks of interaction. In response to these challenges, this thesis aimed to:Develop and demonstrate a set of integrated analytical tools for quantifying and qualifying the spatially explicit trade-offs between offshore spatial claims, in the context of the energy system transition in the North Sea basin.The analytical frameworks developed and used in this study relied and benefited from multiple interactions with multiple research disciplines and methodologies developed as part of the larger network of the ENSYSTRA project
