Connecting corridors, improving everyday mobility

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.

The pilots in Luxembourg

Luxembourg is at the core of Europe’s daily commuting network. The pilots focus on two major highway corridors: the A3 (France–Luxembourg) and A13 (Germany–Luxembourg), both of which face heavy traffic and frequent congestion. The orchestration framework here tackles three main challenges:

  • Optimising commuter traffic on the A3 through carpool and lane management.
  • Coordinating freight and passenger flows across national borders on the A13.
  • Improving sustainability by harmonising speeds and reducing stop-and-go driving.

Through real-time 5G data, connected vehicles, and cross-border coordination, the orchestrator helps create a fluid, fair and energy-efficient highway system.

User stories

The pilots build around real local needs. Each user persona reflects the challenges faced daily in Luxembourg’s highways. Their everyday experiences shape the pilot’s scenarios, ensuring that orchestration benefits commuters, families, and freight operators alike.

Use cases demonstrated

Smarter highways and commuter routes, seamlessly connected

In Luxembourg, CARMONY validates three use cases that show how orchestration enhances traffic flow and safety on major corridors.
From managing carpool lanes within Luxembourg City to harmonising speeds and coordinating cross-border freight, the pilots demonstrate how connected mobility can make every journey smoother, safer, and more sustainable.

Carpool lane optimisation and innovative mobility services

The orchestrator dynamically opens and closes carpool lanes based on real-time traffic density, ensuring efficient and equitable lane use for all.

Cross-border highway traffic optimisation

By combining sensor, vehicle, and logistics data, the orchestrator provides predictive route guidance and mobility suggestions, cutting fuel use and delays.

Speed reduction for daily traffic jam avoidance

The orchestrator proactively harmonises speeds using connected data and variable signage, preventing traffic jams before they form and improving safety.

Local ecosystem and innovation

The Luxembourg pilots are coordinated by LuxMobility and University of Luxembourg.

It connects to Luxembourg’s national CCAM testbed, enabling cross-border demonstrations with France and Germany.
