Synergies between transport modes and air transportation

This project has received funding from the SESAR Joint Undertaking under the European Union’s Horizon 2020 research and innovation programme under grant agreement No 894116


Collaboration is a concept that carries heavy weight when discussing multimodal trips of passengers. For Transport Service Providers (TSPs), it is a method to facilitate a seamless door-to-door (D2D) journey, which is a basic goal set out by the EU in the 2011 Transport White Paper. However, collaboration is a very generic concept that is hard to define. For SYN+AIR, collaboration among modes of transport relates to data sharing among TSPs enabling passengers to enjoy a seamless door-to-door travel experience.

The main objective of SYN+AIR is to develop a Smart Contracts Framework, to tackle the aforementioned challenges.

What is a Smart Contract and how we will develop the framework?

Smart Contracts are agreements among TSPs that define data sharing criteria (scope, parties’ obligations, contract’s time span and fulfilment criteria). Therefore we will achieve this by generating common goals for Transport Service Providers (TSPs) that will justify data sharing, facilitating the user to execute a seamless D2D journey. Customer journeys will be generated for the entire multimodal chain and SYN+AIR will analyse how those journeys can be facilitated through improved planning and operations activities (following the ATFCM phases: strategic, pre-tactical, tactical) powered by data sharing. For the analysis, air travelling is placed in the epicentre; all multimodal chains consider the usage of air travelling. Furthermore, we are going to perform an extensive analysis of travel companions in order to enrich the Data Flow Model defined in the Smart  Contracts Framework to improve the provision of information to the end user: the traveler.

Consequently, a “Smart Contracts Framework” will be generated based on a Business Process Model. Data generated by Travel Companion apps will also be analysed in the context of enriching the Smart Contracts Framework allowing TSPs to improve their activities and execute informed decisions. Finally, SYN+AIR will determine what additional information can be provided, through Travel Companions, to assist the traveler at his multi-modal journey.

Implementation approach

The Work Plan of SYN+AIR is centred on performing research and analysis on the three project axes. WP1 deals with the ethics requirements while WP2 focuses in the coordination of the project. The WP3 Business Policy and WP4 Data exchange axes are corelated; they represent the two sides of the same coin, being the business/soft aspect of collaboration (Business Policy) and the technical/hard aspect of collaboration (Data Exchange). The two axes perform most of the data collection and rudimentary analysis that creates the foundations for the next axis which is the Technology Explortation (WP5).  

In the Technology Exploration axis, SYN+AIR will deliver application-oriented research; SYN+AIR will analyse the design and implementation of the Smart Contracts Framework and its connection with Travel Companion apps. The working methodology is divided into:

  • phase 1: WP2- Business Policy & WP3- Data Exchange
  • phase 2: WP4- Technology Exploration

WP6 is meant for the Dissemination efforts of SYN+AIR.

Universitat Politècnica de Catalunya (UPC) is, with more than 2.000 researchers and 30.000 students, the top technical University in Southern Europe (according to the SCIMAGO Ranking 2013). UPC is a leading research university in the areas of ICTs, Architecture, Industrial and Civil Engineering, Mathematics, Statistics, Life Sciences, Physics, Chemistry, Environment, Energy and Natural Resources. It aims at fostering the improvement of educational and research activities. As of January 2014, UPC is involved in 151 FP7 projects (of which 35 are coordinated) and has a long track of successfully coordinated projects. The Data Management group (DAMA-UPC, is part of the Computer Architecture Department of UPC. It is formed by 10 doctors, engineers and PhD students who work in different projects in collaboration with different national and international institutions and companies. DAMA-UPC has coordinated the FP7 project LDBC (, it is partner of projects IT2Rail (, CoherentPaaS (, SOMATCH ( and was partner of Tetracom (
