SYN+AIR hosted an interesting ER4 workshop on data sharing on the 17th of March and the results are really interesting. A few points just to trigger you (a pager will be shared with you if you subscribe to our newsletter): a. Single ticketing should be extended and include air transport and long distance trains. b. Travellers will only share their data when they see the added value on services. c. Digitalization is a key aspect in coordinated transport d. Smart Contracts Framework can be an enabler for collaboration between TSPs and detail their responsibilities and sharing profit
