CARMONY: Coordinated Action for Responsive Mixed Orchestration and Network Yield

CARMONY is a three-year Horizon Europe project reimagining traffic orchestration for a smarter, safer, and greener Europe.

Why CARMONY?

Transforming traffic in a changing world

As traffic networks become more complex—with the rise of connected, automated, and shared mobility—managing them effectively is a growing challenge.

CARMONY responds to this need by designing a new way to orchestrate traffic, balancing individual needs with societal goals like safety, sustainability, and equity.

Our vision and concept

From fragmented flow to harmonised movement

At the core of CARMONY is the Interlinked Orchestrator, a system that connects road operators, vehicles (manual and automated), and mobility platforms to make traffic smarter and more responsive.

Interlinked Orchestration Framework

A modular framework for coordinating all traffic actors: vehicles, infrastructure, and humans.

Co-Simulation Platform

A testing engine for short-term, long-term, and EU-wide traffic impact analysis.

Smart Interfaces

Real-time dashboards and mobile apps for traffic managers, drivers, and pedestrians.

Governance & Business Models

A fair, inclusive ecosystem for cooperation, aligning the interests of public authorities, fleet operators, and private users.

How it works

Real-time insights. Human-focused decisions.

CARMONY uses real-time data, long-term simulations, and human oversight to suggest the best actions—without removing individual freedom of choice.

Collect data from vehicles, infrastructure, and environment

Real-time data from sensors, vehicles, and users feed into the orchestrator.

Simulate traffic scenarios in real-time

The system simulates scenarios and evaluates the best course of action.

Suggest best actions for users and managers

Suggested actions are presented to traffic managers and drivers.

Adapt the system based on human feedback

A feedback loop improves the system over time.

Tested in the real world

Where we demonstrate the impact

Demonstrated in Murcia, Spain (urban) and Luxembourg (highway/cross-border) environments, the orchestrator is tested in both real-world and virtual settings.

Murcia, Spain

Traffic congestion, emergency response, and low-emission zones in a dynamic urban setting.

Highway A13, Schengen – Germany & Luxembourg border

Cross-border corridor, 5G infrastructure, congestion mitigation.

Highway A3, Luxembourg City

Carpool lane optimisation, public transport integration.

Why it matters

Why CARMONY stands out

Tested, not just theorized

Real pilots in diverse contexts: urban, rural, highway, and international.

Human in the loop

Technology that enhances, not replaces, human decision-making.

Built for trust

Ethical data management, user transparency, and stakeholder co-creation at every step.

Ready for scale

Designed to guide national and EU-wide implementation with open standards and replicable models.
