Gaia Public Transport creates and uses real-time digital twin entities within the public transport domain such as vehicles, journeys, and people. Each physical entity and object has its own digital representation that executes and runs in real-time and can act on its planned data or occurring events. The digital twins are constantly updated and retain the state of their physical twins. It makes it possible to apply logic and rules in the cloud to create and control relevant information at any given moment. This information is distributed in all channels to all stakeholders in real-time.
