Trust is the backbone of seamless mobility. In multimodal transport, delays, missed connections, and passenger frustration often result from a lack of clear agreements between operators. SIGN-AIR gives operators the digital tools to create, manage, and execute smart contracts and data-sharing agreements, turning coordination into a real-time, automated process.

Imagine a train delay where passengers risk missing their flight. With SIGN-AIR, agreements between the rail company and the airline can automatically trigger actions, like holding the plane, ensuring smoother journeys, happier passengers, and fewer emissions from disrupted travel.

For Europe, this translates into:

• Greener mobility through better coordination and reduced CO₂
• Happier travellers with real disruption management and single-ticketing
• Efficient operations where digital contracts and shared data remove friction

At its core, SIGN-AIR shows that the future of mobility is built on collaboration, not isolated systems. By harmonising legal, technical, and business frameworks, the project creates the foundation for trust in multimodal travel. Trust is what will finally make seamless journeys the new normal across Europe.

As we move from research to real-world testing (TRL7), AETHON contributes its expertise in AI-driven engineering and automation to help bring this vision to life. Because building the future of transport is about connecting systems, operators, and expectations.

We had the opportunity to share the outcomes of the project, with our project stakeholders, and also collect their valuable insight!

As the project comes to an end, we aim to continue our work on the Smart Contracts framework, created within the project.

Keep an eye on the new inspiring initiatives that follow!
