EU-US Twinning

The European Commission (EC) and the United States Department of Transportation (USDOT) have been in discussion to sponsor a twinning initiative to encourage collaboration between mobility-related projects in Europe and the United States.


Working together

The CoEXist project has been selected as the EU project to establish a twinning relationship with relevant projects funded by the USDOT, on the analysis, modelling and simulation (AMS) of CAVs, aiming towards the coordination of activities and research collaboration, on the basis of mutual benefit.

A Twinning Agreement was signed on 26th February 2018 between CoEXist and two FHWA funded research projects:

  • Development of an AMS Framework for CAV systems, which aims to determine the main knowledge, data and tool gaps associated with modelling CAV applications –and to create a conceptual AMS framework that addresses these gaps
  • Developing AMS Tools for CAV Applications, with the goal of developing a uniform suite of AMS tools and implementation guidance –producing an accessible, promotable, ready-to-use toolbox for state DOTs and MPOs.

The twinning partners agreed to actively cooperate and exchange on the following topics of their research projects:

  • Development of an AMS Framework’ for connected and automated vehicles;
  • Exchange of information about use cases and case studies that will apply the AMS Framework; and
  • Cooperation on AMS tool development for connected and automated vehicles.

The twinning activities encompass quarterly conference calls, the exchange of deliverables and workshops at conferences. Face-to-face workshops have taken place in the frame of TRB annual meetings in Washington D.C. (USA) on 2018 and 2019, and within CoEXist’s Consortium Meeting in Helmond, after the ITS European Congress 2019.

During these workshops, EU and US researches presented updates of the work and progress made in their respective projects, spurring interesting discussions around the different conceptual and methodological approaches, and providing valuable feedback for its improvement.

This exchange of ideas contributed towards the strategic aim of reaching a common understanding on key research topics, such as: the development of a framework and effective tools to enable CAV transport planning; the definition of CAV control logics and driving behavioural parameters; the safe integration of CAVs in mixed road environments; the interaction and communication of CAVs with other road users such as pedestrians, bicycle drivers and conventional vehicles; the challenges and opportunities of V2I (Vehicle-to-Infrastructure) communication; the design and adaptation requirements of road infrastructure (e.g., US DOT’s National Reference Architecture for ITS); and the assessment of CAV’s impacts on road infrastructure, among others.
