The proposed project “Coherent Support for Mobility.E Strategy” (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 COSMOS project will assist the Lighthouse Initiative Advisory Service (LIASE) in the continuous identification and prioritisation of research topics and the subsequent translation into an action plan to support roadmap implementation. It will map the Mobility.E ecosystem by comparing the Strategic Research Agendas of ECSEL and of 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 will analyse the implementation of these roadmaps into funded projects. This approach shall enable the identification of white spots and gaps and it will reveal the potentials for bridging these with a dedicated implementation plan. This content-related work will be 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 will be continuation and further development of the ECA 2030 networking events series. The contractual and associated partners of COSMOS are representing the Mobility.E lighthouse projects, the LIASE and the governing board of ECSEL, the editorial team of the “Transport and Smart Mobility” chapter of the ECSEL Joint SRA and further relevant stakeholders. By working together in a coherent manner in processes for strategy development and network support they form a strong backbone of the community to be built for the Mobility.E Lighthouse of ECSEL.
