CARMONY is a Horizon Europe project working to make traffic management across Europe smarter, safer and more sustainable. By connecting vehicles, infrastructure, traffic managers and mobility services in real time, the project aims to improve how traffic is orchestrated in increasingly complex transport environments.
As connected, cooperative and automated mobility becomes more widespread, traffic systems need to respond more dynamically to changing conditions, user needs and public policy goals. CARMONY addresses this challenge by developing a new orchestration approach that balances efficiency, safety, sustainability and fairness across mixed traffic environments.
CARMONY is rethinking traffic management through a next-generation orchestration framework that enables better coordination between public authorities, road operators, vehicles, mobility platforms and users.
The project develops and validates tools and models that support responsive traffic management in complex urban and highway contexts. Through real-world demonstrations and advanced co-simulation, CARMONY is building the foundations for traffic systems that are more adaptive, human-centred and better aligned with broader societal goals.
CARMONY aims to:
Interlinked Orchestration Framework
CARMONY is developing a modular framework that connects infrastructure, vehicles, traffic managers and mobility platforms under shared operational logic. This framework supports coordination between public and private stakeholders while preserving user choice and ensuring transparent decision-making.
Traffic Orchestration Co-Simulation Platform
The project is building a co-simulation environment that combines real-world data, orchestration logic and traffic simulation tools. This enables stakeholders to test, compare and refine traffic strategies before deployment in live environments.
Smart Interfaces
CARMONY includes dashboards, data connectors and user-facing applications that provide real-time information, alerts and recommendations to traffic managers, drivers and mobility operators.
Governance and business models
To support long-term uptake, the project is also developing governance structures, incentive models and cooperation mechanisms that make orchestration feasible and attractive for both public and private actors.
CARMONY validates its approach through demonstrations in two distinct environments:
These demonstrations help assess how orchestration solutions perform in different operational and governance contexts.
CARMONY will contribute to safer, more efficient and more sustainable mobility by improving coordination across transport actors and systems. The project is expected to deliver benefits for:
Through the ALICE Liaison Programme, CARMONY contributes to broader dialogue and collaboration on innovation in transport and logistics. Its work is relevant to the digitalisation and optimisation of transport systems and supports the development of smarter, more connected mobility ecosystems across Europe.
CARMONY brings together a multidisciplinary consortium of research centres, technology developers, public authorities and mobility specialists from across Europe, including:
