Testing of connected and automated driving is essential for technology assessment and development, safety validation, to anticipate user and customer expectations and to analyze the impact on society. Producing consistent and comparable results requires the sharing of the basic notions used to build and describe CCAM experiments: service, function, ODD, itinerary, use case, scenarios… to prepare the great steps towards deployment: validation, homologation, integration in the transport systems. The workshop will introduce the first debate on the stakes, steps and perspectives of aligning visions among all stakeholders. The session will highlight the importance of this alignment, through exchanges between European and International speakers from the main stakeholders involved (OEMs, shuttle manufacturers, Public transport, public authorities …) and approaches and lessons learned from ongoing pilot projects with the aim to identifying the priorities and actions to be engaged. The second part of the session will focus on the expectations from users and public authorities to maximize the positive impacts of the projects.
