EU-US Twinning

The CoExist project is part of a larger cooperation between the European Commission (EC) and the United States Department of Transportation (USDOT). Both organisations are working together in the form of a twinning initiative to encourage collaboration between mobility-related projects in Europe and the United States.

Working together

The CoEXist project has established a twinning relationship on the analysis, modelling and simulation (AMS) of CAVs, aiming towards the coordination of activities and research collaboration. A twinning agreement was signed on 26 February 2018 between CoEXist and two research projects, which were funded by the Federal Highway Administration (FHWA). The cooperation focuses on:

  • Developing an analysis, modeling and simulation (AMS) tool for CAVs 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 are cooperating and sharing their expertise on case studies that apply the AMS Framework and on AMS tool development for connected and automated vehicles. The twinning activities encompass quarterly conference calls, the exchange of deliverables and workshops at conferences.

During these workshops, EU and US researchers have shared 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 and the assessment of CAV’s impacts on road infrastructure, among others.
