Multimodal digital mobility services (MDMS) are digital platforms that integrate transport modes such as rail, buses, bikes, taxis and car-sharing into a single interface for planning, booking and payment. MDMS aim to improve convenience, journey choice and cost efficiency, while supporting more sustainable and integrated mobility across Europe.

The EU considers MDMS to be a strategic component of the Green Deal and the sustainable and smart mobility strategy to reduce emissions and strengthen the transport Single Market. Key policy tools include the Directive on Intelligent Transport Systems (ITS), the European mobility data space, and initiatives promoting interoperable data and seamless multimodal travel. Major policy debates focus on data sharing, interoperability, integrated ticketing, passenger rights, liability for disruptions, and platform governance. The Multimodal Passenger Mobility Forum highlighted challenges around FRAND (fair, reasonable and non-discriminatory) principles, self-preferencing, enforcement, data protection and data quality requirements. A Eurobarometer survey shows that many users still find multimodal booking difficult due to fragmented systems, poor connections, higher costs and uncertainty about transfers.

Stakeholders are divided, with transport operators resisting mandatory data and ticketing access, while digital platforms support stronger interoperability and openness. Consumer and environmental groups generally support MDMS for improving transparency, competition, and shifting demand towards low-emission transport. Researchers consider MDMS promising but not fully mature, pointing to persistent issues in interoperability, technical standards, cybersecurity, and governance. Overall, effective MDMS deployment requires balanced regulation, harmonised standards, investment in infrastructure, and strong public-private coordination.
