The European Commission’s Sustainable and Smart Mobility Strategy focuses on a fully integrated and seamless multimodal mobility system. For long-distance, intra-European travel, this should be enabled by a high-quality transport network with high-speed rail (HSR) services on short-haul distances and with clean aviation services improving the coverage of longer-haul routes. A seamless passenger experience and interoperability between different transport providers will be enabled by inte- grating airports as multimodal nodes in the air traffic management (ATM) network.

The MultiModX project lays the foundation of a multimodal European transport system in which air and rail networks are planned and managed in a coordinated manner to maximise the efficiency, predictability, environmental sustainability and resilience of the door-to-door passenger journey.

A Schedule Design Solution will enable the coordinated design of air and rail schedules according to expected passenger demand behaviour. The Disruption Management Solution will support decision-makers’ response to disruption events (e.g. longer delays, missed connections, denied boarding, cancellations) in real time in order to minimise the impact on the passengers, benefiting from the extension of the airport collaborative decision-making concept to other transport modes. The MultiModX Performance Assessment Solution will support the design, implementation and evaluation of these multimodal solutions by enabling ex-ante assessment and ex-post monitoring of their impact on a comprehensive set of key performance indicators like overall travel time, accessibility or CO2 emissions. In order to nurture the conditions for the transfer of the MultiModX Solutions to the subsequent stages of the innovative solutions, air and rail stakeholders are engaged for validation.

Three solutions to enable integrated, passenger-centric air-rail networks
To maximise the efficiency, predictability, environmental sus- tainability and resilience of the door-to-door passenger journey, future air and rail networks have to be planned and managed in a coordinated manner.

Strategic assessment
The performance of future integrated, passenger-centric multimodal air-rail networks for Europe will be assessed on a strategic and tactical level.
