COSMOS aims at supporting the ECSEL Lighthouse Initiative Mobility.E in its endeavour to accelerate the deployment of clean and automated road mobility solutions and the realisation of the associated socio-economic benefits. For this purpose, the project assists the LIASE in the continuous identification and prioritisation of research topics and the subsequent translation into an action plan to support roadmap implementation. The COSMOS project maps the Mobility.E ecosystem by comparing the strategic research agendas of ECSEL and the European Technology Platforms AENEAS, EPoSS and ARTEMIS-IA involved therein with those of stakeholders further down the value chain, such as ERTRAC, EUCAR, CLEPA, and EATA regarding complementarity and coherence, and it analyses the implementation of these roadmaps into funded projects. This approach shall enable the identification of white spots and gaps and reveal the potentials for bridging these with a dedicated implementation plan. This content-related work is enabled by a set of effective network support measures in terms of stakeholder engagement and collaboration, events and workshops as well as dissemination building an extensive Stakeholder Circle. One of the visible activities supported by COSMOS is the continuation and further development of the ECA 2030 networking events series.
