An arrangement, of functionally connected electronic devices includes: a data input entity, configured to obtain user in-formation relative to a plurality of users, data indicative of trust between multiple users and data indicative of a number of ride requests and ride offers by the users, a trust network knowledgebase entity configured to establish and manage a number of trust networks on the basis of the obtained data. The knowledgebase entity groups a plurality of users into a number of trust networks, a scheduling entity configured, on the basis of the obtained data, to determine a potential transport sharing scenario for a plurality of users belonging to the same trust network. The scheduling entity is configured to find potential matches between the ride requests and ride offers to determine the scenario, and a data output entity configured to indicate the scenario to multiple users of the plurality.
