Orchestrating the city for safer, greener mobility
In Murcia, CARMONY brings orchestration to life in a bustling southern European city.
Here, the project demonstrates how real-time coordination between people, vehicles, and infrastructure can make traffic management cleaner, faster, and more human-centred.
The pilot in Murcia
Murcia is a lighthouse site for urban orchestration. The pilot explores how the Interlinked Orchestrator supports the city’s shift towards sustainable mobility — integrating connected vehicles, public transport, and digital infrastructure into one responsive ecosystem. The focus is on:
- Reducing congestion and travel times through dynamic traffic management.
- Supporting Low Emission Zones (LEZ) to encourage cleaner urban mobility.
- Improving safety and emergency response through smart corridor management.
- Building citizen trust with transparent, user-oriented tools.
The Murcia pilot connects seamlessly with the city’s existing Smart Mobility Platform operated by ETRA Group, forming part of the municipal traffic management system.
User stories
The pilot builds around real local needs. Each user persona reflects the challenges faced daily in Murcia’s urban mobility. Through orchestration, each of them experiences a smarter, safer, and more predictable city.
Carmen
A young office worker, struggles with the new Low Emission Zone and limited parking near her workplace.
Vincente
An ambulance driver, faces delays caused by congestion and uncoordinated emergency routes.
Patricia
A traffic operator, wants more accurate, real-time insights to manage city traffic effectively.
Use cases demonstrated
Turning urban challenges into coordinated mobility
In Murcia, CARMONY tests three real-world scenarios that show how orchestration improves daily mobility — reducing congestion, supporting Low Emission Zones, and enabling faster, safer emergency responses.
UC1
Traffic Management optimisation including Low Emission Zones
The orchestrator uses live sensor and vehicle data to suggest optimal routes, manage LEZ access, and guide drivers to available parking or public transport options — reducing CO₂ and congestion.
UC2
Critical road blockage
When an accident or breakdown occurs, the orchestrator instantly informs drivers and emergency services, rerouting vehicles and shortening response times.
UC3
Emergency corridor activation
In collaboration with Murcia’s emergency teams, the orchestrator dynamically controls traffic lights and connected vehicles to clear corridors for ambulances, ensuring faster arrival with minimal disruption to others.
Local ecosystem and innovation
The Murcia pilot is led by ETRA I+D in cooperation with the Municipality of Murcia, and Tecnalia.
It builds upon the city’s Smart Mobility Platform (MISTRAL) and integrates digital twin technologies to test orchestration in both real and simulated environments.
The results will support Murcia’s transition towards a more resilient and sustainable mobility system.
ETRA I+D – ETRA Group
ETRA I+D is the hi-tech unit within ETRA Group, one of the leading industrial groups in Spain. The activity of ETRA I+D is centred in three main activity lines: energy management, smart mobility (including EV charging infrastructure management, traffic solutions, and PT systems) and cyber physical security.
City of Murcia – Smart Mobility Department
The City of Murcia is an active mid-sized urban hub in southeastern Spain, committed to modernising its transport systems through digital innovation and sustainability. As a municipal authority, Murcia plays a key role in piloting new mobility solutions to improve the daily lives of its citizens.

Discover also the Luxembourg pilots
In Luxembourg, CARMONY demonstrates orchestration in two complementary settings: the busy A3 urban highway connecting the capital to its southern suburbs, and the A13 cross-border corridor linking Luxembourg with Germany. Together, they represent one of Europe’s most challenging mobility environments, where dense commuter flows, freight transport, and sustainability targets meet.
