CHORUS, a recently launched EU-funded research project under Horizon Europe, has launched a series of surveys to collect both societal and technical requirements that will help shape the future of Connected, Cooperative and Automated Mobility (CCAM) in Europe.
The surveys target citizens, including vulnerable road users, as well as CCAM stakeholders such as public authorities, mobility operators, infrastructure managers, and technology providers involved in CHORUS demonstration sites.
Running from 2025 to 2028, CHORUS (Coordination of Heterogeneous Actors in Mixed Traffic within CCAM – Grant Agreement No. 101202981) aims to make road transport safer, more efficient, and more inclusive by enabling better coordination between autonomous vehicles, public transport, traffic management systems, and other mobility services.
Take part in the CHORUS surveys
CHORUS will test its solutions in seven Demonstration Sites: Paris-Saclay (France), Oxfordshire (United Kingdom), Trikala (Greece), Bern, Geneva and Zurich (Switzerland), and Helsinki (Finland).
Are you a resident of one of these areas?
Or are you a CCAM stakeholder involved in local mobility planning, operations, or innovation in the interested areas?
Then we invite you to take part in the CHORUS surveys. Participation is anonymous, fully GDPR-compliant, and plays a key role in ensuring that future CCAM solutions reflect real-world needs and expectations.
- Technical Requirements Survey - for CCAM Stakeholders
- Societal Requirements surveys - for citizens and general users
(Both surveys are available in English, French, German, Greek, and Finnish)
Why these surveys matter
The surveys combine two complementary approaches:
User surveys gather opinions, expectations, concerns, and wishes of citizens, including vulnerable road users and people with mobility challenges, to ensure that CCAM solutions are socially acceptable and inclusive.
Technical stakeholder surveys collect input from CCAM actors to define and validate technical requirements for CHORUS use cases, covering areas such as secure data sharing, multimodal mobility services, traffic orchestration, cooperative perception, and governance frameworks.
All responses will be analysed alongside results from local stakeholder forums across the demonstration sites. Findings will be consolidated to identify both common and site-specific needs, informing CHORUS technical specifications and project deliverables. Results will be published only in aggregated and anonymised form.
Demonstrations across seven European territories
CHORUS brings together 26 partners from across Europe and is validating its solutions through demonstrations in seven European territories:
Paris-Saclay (France), Oxfordshire (United Kingdom), Trikala (Greece), Bern, Geneva and Zurich (Switzerland), and Helsinki (Finland).
These diverse environments allow CHORUS to address key challenges of mixed traffic, vulnerable road user safety, secure data exchange, and coordination between multiple mobility actors in real-world conditions.
About CHORUS and the project partners
CHORUS (Horizon Europe, Grant Agreement No. 101202981) is coordinated by ICCS-NTUA (Institute of Communication and Computer Systems).
ERTICO – ITS Europe leads dissemination and communication activities within the project, as part of its broader commitment to advancing CCAM solutions that contribute to smarter, greener, and more inclusive mobility for all.
