Mobility presentation at Data Science In Aviation workshop (EASA, 2016)

The annual event exploring Data Science in Aviation (ComplexWorld funded; organized by Innaxis) has recently celebrated its fourth edition this past September 8th 2016. The event was hosted on the EASA premises in Cologne, Germany . This year it highlighted a presentation of the DATASET2050 project, “Data Science for Mobility”, by project coordinator Samuel Cristobal (Innaxis).



On the Data Science In Aviation event:

Previous editions of the Data Science in Aviation event were hosted in Madrid 2013, Paris 2014 and Brussels 2015. The popular event usually draws attendance from more than 80 individuals from top European and worldwide aviation entities (including Airbus, Eurocontrol, Boeing, EASA, Airlines, Airports, ANSPs, SESAR , Universities, etc) along with ICT and data-related entities (including CERN researchers, Fraunhofer, Infrastructure-related, and various universities). Notable presenters from the 2016 edition included EASA, Innaxis, NATS, Eurocontrol, Boeing, ENAC and Fraunhofer.

In terms of the event agenda and content, the presentations has traditionally outlined how data science is understood as a useful set of fundamental principles that support and guide the principled extraction of information and knowledge from aviation data. Furthermore, the discipline leans on well-known data-mining techniques, and goes far beyond these techniques with successful data-science paradigms which provide specific applications in various air transport areas (safety, performance, mobility etc).


On DATASET2050 Samuel’s presentation:

The event also highlighted a key presentation from Innaxis project coordinator, Samuel Cristobal. Samuel presented five different points on data science in aviation.

  • First, he explained how some of the data science tools, techniques and concepts have been used in the mobility context, specifically using the DATASET2050 project as a case example.
  • Second, Samuel explained the different door to door phases under analysis (door-kerb; kerb-gate; gate-gate; kerb-door), which helps to delve deeper in the different data science components within aviation phases.
  • Third, Samuel outlined the different links between project objectives and overall Flightpath2050 goals.
  • The fourth point explored mobility data in Europe, and the value of the DATASET approach in this context.
  • The presentation concluded with a fifth and final point announcing the next communication actions. The full presentation can be accessed here: https://www.dropbox.com/s/91julyl8gsij2k9/DATASET_SC_v1.pdf?dl=0


In sum, the fourth edition of the Data Science in Aviation event was an excellent opportunity for dissemination of DATASET2050. This was in conjunction with a fruitful exchange of ideas with other aviation data scientists, some of whom working with similar tools in other sub-areas far from mobility. We hope to continue this momentum of knowledge exchange and look forward to a potential fifth edition of the popular event.

Innaxis at ICRAT 2016

Between June 20 to 24, our PhD student Seddik Belkoura went at the very doorstep of the famous Rocky Balboa Statue, as the seventh edition of the International Conference on Air Transport (ICRAT) was held at Drexel University (Philadelphia, USA) . This successful event, co-organised by the FAA (Federal Aviation Administration-USA) and EUROCONTROL, put the emphasis the next generation of researchers, with a strong participations of students keen on interacting with more mature and expert minds.


In Seddik’s presentation during the conference, he wanted to highlight the dynamic nature of the delay propagation process in Air Transportation. He showed in his talk that abnormal delays at a given airport (those with an unexpected magnitude) can perturb the way the delays are propagated in “normal” conditions. The quantity of “surprise” necessary to disrupt an airport can be quantifiable, and an approximation of the additional delay necessary to disrupt the propagative dynamics of each airport have been proposed by Seddik. The audience’s interest at this point indicated that work have still have to be done to master all the complex behaviours of some processes like delay propagations.


The event was a success, and the areas of investigation within Air Transportation were quite wide. One special note have been noticed by Seddik: the growing number of presentation (and attention) to drones. The recentness of the concept and the velocity with which it develops and spreads is such that it deserves a special attention. Legislation are not yet fully explicit and a lot of work to design the “future” if happening right now. It is the moment to use our experience with Aviation to better fashion the drone system. Specifically, the importance of data should be pointed out, to allow a better development and a continuous improvement of this new and growing complex system.


Seddik’s paper and the presentation about drones will be soon available on the official website of the conference (http://www.icrat.org/)



Passengers’ environmental awareness and travel behaviour

Passengers’ travel behaviour can be influenced by various factors, such as disposable income, travel purpose, age group or technological affinity (see also #blogpost7 Passengers expectations: door-to-door travel and beyond). One of these influential factors is the environmental awareness of passengers and in which way it impacts – or even alters – travel behaviour.

Air transportation emits greenhouse gases and hence has a potential harmful effect on our environment in the form of CO2 emissions, for example. Passengers contribute to this by their choice of means of transport, their choice of holiday destinations and kilometres travelled (Cohen and Higham, 2011; Brouwer et al., 2008).

Overall, air travel passengers seem to have a basic understanding of the environmental impact and many also have pro-environmental values. However, according to several studies it does not result into behaviour changes of passengers yet. It is hence not a factor influencing their holiday planning, the choice of a destination and the type of transportation (Hares et al., 2009; Böhler et al., 2006). Research also reveals that the willingness of passengers to pay for carbon offsetting schemes, one possibility to neutralize emissions generated by one’s own journey without compromising the means of transport or influencing the decision on holiday destinations, is low as well (Eijgelaar, 2009; Mair, 2011).

The three main barriers towards pro-environmental behaviour change are a lack of alternative transport systems, the high value of holidays with the freedom to travel to every destination one wants, and the lack of feeling personal responsibility for climate change (Hares et al., 2009; Böhler et al., 2006). However, within some recent studies, evidence emerged showing an increasingly pro-environmental awareness in passengers’ mind-set and a willingness to actually change air travel behaviour in the future (Cohen and Higham, 2011; Gössling et al., 2009).

To sum up, environmental awareness among passengers seems to be already present but does not lead to current behaviour changes. This, among other factors, will be explored within DATASET2050 and it will be modelled how such drivers influence the travel demand of air transport passengers in the future.

EU Door-to-Door Mobility Workshop – Abstracts

  • Session 1. Challenges of a data-driven model

The current state of mobility in Europe – University of Westminster
The foundations of the DATASET2050 model are described in this presentation, along with some of the corresponding data sources used in its construction. Using mobility, we show roughly how far from the target we are currently in Europe, with optimistic and less optimistic scenarios. We present the order of magnitude of the trip segments and introduce the main problematic. Finally, we have a brief look at how uncertainty is playing a key role right now in transportation with the creation of buffers – pure interplay between supply and demand.

Meeting the passenger’s demand: current and future – Bauhaus Luftfahrt
This presentation illustrates the passenger-centric approach taken within the DATASET2050 project by developing current demand profiles. It elaborates different aspects influencing passenger demand such as age, income, household structure, or technological affinity. Based on the analysis of European data, a range of passenger profiles and respective characteristics are derived. These determine the requirements passengers have during their journey and hence the time spent in different processes. Furthermore, data on European mobility behaviour yields different archetype journeys for these passengers.

Developing a new model for European mobility – Innaxis
The DATASET2050 mobility model is a mathematical framework aiming to represent the European door-to-door transportation network. The model has a stochastic approach inherited from complex networks theory, but is ultimately implemented using data science tools. This presentation will address how journey lengths are estimated as an aggregation of multiple random sub-processes and how decision networks are driven by stochastic supply and demand profiles. Several candidate mobility metrics will also be discussed and how the model can be used, to some extent, to analyse future scenarios.

  • Session 2. Further exploring the journey process phase by phase – where are the efficiency gains?

Door-to-kerb – Prof. Dr. Kai Nagel, Technical University of Berlin
The MATSim (Multi Agent Transport Simulation) project is involved with the microscopic simulation of individual travellers at the regional or even national scale. The approach starts from a synthetic population where real humans are replaced by statistical equivalents, builds full daily schedules for them, and follows them through their day with a special focus on the transport system. The system also allows us to run detailed analysis tasks; for example, investigating the accessibility of households to all kinds of services by all means of transport. Clearly, it would also be possible to follow synthetic persons from home or workplace to an airport, or from airport to workplace or home. This presentation will demonstrate current capabilities and discuss possible extensions to MATSim.

Kerb-to-gate – Dr. Genovefa Kefalidou, Horizon 2020 PASSME project
Understanding passenger, airports and airlines’ needs promptly, transforming them into intelligence and adjusting services based on this intelligence is now even more demanding. PASSME is an EU-Horizon 2020-funded project in which we aim to provide innovations to modern journey challenges while at airports. We work on innovations to enhance passengers’ experiences (including reducing stress), providing real-time personalised information, improving interiors and luggage flow and forecasting passenger flow. We identify that passenger needs intertwine strongly with airport and airline needs, manifesting opportunities to build a relationshipamongst all these stakeholders through the use of mobile, back-end and situated innovations. This relationship demands to be maintained throughout the different airport touch points (e.g. kerb-to-gate) to facilitate and optimise the journey process as knock-on effects are transferred between phases, often causing further delays and dissatisfaction.

Gate-to-gate – Steve Williams, NATS
This presentation considers a selection of SESAR concepts, considering changes from flight plans to business trajectories and from distance-based to time-based spacing, also including extended arrival management horizons and system-wide information management (SWIM). It considers the relevance of SESAR to future transport goals: what could SESAR provide to other transport modes, what are the limitations, and why are the limitations unlikely to change? The importance of air traffic management data accuracy is also discussed, and why data are much more precise once an aircraft has left the ground.

  • Session 3. Looking ahead to 2035 and 2050

Futures near and far – Christoph Schneider, Munich Airport
There are many potentially disrupting developments that add a lot of uncertainty when it comes to predicting mobility in 2035. The ACARE mobility vision does not contradict any of these trends. The European aviation market may appear to mature wrt growth rates, but absolute growth will most likely still be huge. Airport capacity is set to be the limiting factor with little hope of being coped with. Munich Airport is very actively engaged in activities to increase capacity, improve intermodality and enhance passenger experience by innovative digital products – these areas are common denominators for mobility in 2035.

ComplexWorld: Linking Complexity and Data Science in ATM

This year we celebrated the 5th anniversary of ComplexWorld. As we reflect over the years to 2011, when Innaxis first launched the network, it’s easy to find many reasons to feel proud and grateful of our partners and participants of the network. ComplexWorld emerged from the idea of applying complexity science techniques to better understand the Air Traffic Management behaviour and the relationships among its different agents. At the network’s inception, it was considered a new and unfamiliar concept, but promising nonetheless. Now the concept has become a reality, after fruitful 5 years of ComplexWorld network development, along with 8 PhDs and 10 projects. The number of references in the field has increased significantly since 2011. To illustrate, the first graph below shows the growth of the number of papers published including the text “air transport” and “complex networks” since 2005. The second graph represents the number of those papers corresponding citations. (Data source: Thomson Reuters’ Web of Science)



In order to provide some direction to the purpose of the ComplexWorld network and specifically, the analysis of the air transport network as a complex system, the ComplexWorld partners Innaxis, University of Seville, University of Westminster, University of Palermo, along with NLR and DLR, identified 5 research challenges in which complexity science could provide a completely new perspective and deeper understanding of system performance. Those challenges include: resilience, metrics, emergent behaviour, data science and uncertainty, which have been our research pillars for the ComplexWorld network; enabling significant progress in those fields, previously insignificantly addressed by traditional and classical models. This the nexus of complexity science and air traffic management has garnered so much attention that soon a book will be released for the public, published under the title, “Complexity Science in air traffic management”. If you cannot wait to have it on your hands, you are in luck! The book is now available on Amazon.

Through the evolution of research within these five pillars, a key insight emerged that drove a conviction: data science was not merely one of the five pillars, but rather the key pillar that would foster the most significant and efficient progress within the other four areas. However, the aviation sector was not fully prepared to move forward quickly with the application of data science techniques as challenges related to data confidentiality, data sharing, and lack of appropriate data management infrastructures presented barriers for advancement. Therefore, with the objective of eliminating or reducing these barriers, in 2013 ComplexWorld organized the first Data Science in Aviation Workshop (DSIAW). The aim was to bring together aviation stakeholders willing to extract knowledge from their available data, with data scientists and experts from other sectors assisting by demonstrating the potential of data science with real examples of ongoing initiatives and recent work. The event was a complete success in terms of invited speaker expertise, but more importantly, the event was outstanding in terms of audience engagement, so much so that DSIAW has became an annual workshop thanks to the support of Eurocontrol and the SJU.

Year after year we have enthusiastically worked to bring relevant experts together to present their work on the application of data science techniques to enable an improvement on their business performance. Furthermore, we feel this sector is moving in the right direction as we see the number of success cases in this sector grow significantly. This year, we are organizing the 4th edition of the DSIAW, which will be celebrated September 8th and 9th at EASA HQ in Cologne. The workshop will be opened by Mr. Luc Tytgat, EASA Strategy and Safety Management Director, and will include presentations about different data science applications, including:

  • Air navigation (UK NATS and Eurocontrol-MUAC),
  • Aviation safety (Innaxis and AESA – Spanish Aviation Safety Agency),
  • Mobility (Boeing and Innaxis)
  • Infrastructure and visualization (Fraunhofer ITWM and ENAC)

Registration is now open so you are invited to join us and participate in the debates. At DSIAW you will also have the opportunity of attending the presentation of the “Complexity Challenges” report, a report in which we have developed in the framework of SESAR Exploratory Research along with 18 external experts who have provided their assessment on how the complexity challenges have been addressed by the different ComplexWorld related activities within these last five years, and the existing gaps and opportunities for future research in the field. We highly encourage you to attend this 1.5 days event and to be an active part of the definition of future research lines in the field of complexity in air transport. If you cannot attend, videos of the event will be uploaded to our vimeo channel and wiki, where you will catch some of the unprecedented conversations and become an active participant in the dialogues.

Mainstream economics are not delivering what humanity needs

Innaxis at the XIII International Colloquium of the World Academy of Arts and Science (WAAS)

Lisbon 11th -13th May 2016


WAAS members where invited during a three day conference at the Lisbon School of Economics and Management to discuss “Post 2008 Global Dynamics and Structural Changes: Economic, Political and Eco-Societal Transitions”.

The international financial crisis in 2008 sparked a plea for systemic paradigm shift regarding the orientation of policies of economic management. The request amongst decision makers and international organizations for profound changes in our economic system have unfortunately only been very short-lived.

Instead a “business as usual” agenda has been put in place driven by unquestioned mainstream economic theories.

However the present interconnected crises of unemployment, growing inequality and environmental destruction (just to name some of them) show that these challenges are not correctly addressed by the current dominant framework of economic thought.

In light of these developments, the aim of the meeting was to discuss the future of “Economics” as a science, its inherent shortfalls and usefulness.

The participants of the colloquium examined the changes since the period in which most prevalent economic concepts were formulated and assessed their relevance to the radical changes that have transformed economic activity since then.

Carlos Alvarez Pereira President of Innaxis, presented at the Colloquia « Towards a Society of Living » the vision of a new work programme currently under development at Innaxis. In his presentation he explored the shortcomings of our current understanding of economics and the gridlocks that prevent us from transforming our societies. In addition, he stressed that the transformation paths have to go beyond narratives based on technology-driven solutions, which are currently, in times of rapid digitalization, very appealing but insufficient or even misleading. He proposed pathways for reformulating economics as part of a larger, complex societal-scale system which addresses human needs in harmony with nature.

During the meeting WAAS members decided to produce a new academic curriculum for students, based on alternative economic theories including human-centered, value-based, ecologically sustainable economic thinking.
