SIGN-AIR: Multimodal travel starts with data sharing

By streamlining the sharing of data between transportation service providers, the SIGN-AIR project aims to make multimodal travel a reality.

The future of travel may be multimodal, but that future will not materialise unless transportation service providers (TSPs) share data.

The SESAR JU-supported initiative is focused on addressing those roadblocks that prevent efficient collaboration and data sharing amongst TSPs.

The project looks to streamline the creation and management of Data Sharing Agreements (DSAs) and Smart Contracts (SCs). To do so, it is building a secure web platform where TSPs from different modes can create, monitor and modify signed contracts.

Additionally, the platform supports the integration of multimodal schedules, proposing itineraries with acceptable transfer times that are appealing to passengers. When disruptions occur, it analyses affected journeys, predicts cascading effects on subsequent legs and proposes real-time rerouting options to passengers, thus enhancing resilience and enabling single ticketing across modes.

Reliable and resilient journeys

With SIGN-AIR, the contracts would automate the exchange of relevant information, allowing for a proactive rebooking or alternative travel arrangements to be made, thus significantly improving the overall passenger experience.

The SIGN-AIR platform can also be used to identify sustainable alternatives to replace short-haul flights and enable the introduction of emerging mobility such as ‘flying taxis’.
