A method is disclosed for real-time and dynamic event-related information derivation and dissemination by a road infrastructure to control, coordinate and consolidate information from at least one observation entity (10), the observation entity (10) being preferably an independent vehicle (1), a mobile device or the like. The method comprises receiving, by a road infrastructure server of the road infrastructure, event information from one or multiple observation entities (10), wherein each of the observation entities (10) provides its event information as an event information frame that comprises an event data record including a number of attributes together with a unique identifier referencing the event data record, collecting and analyzing the event information frames received from the observation entities (10) and processing them to generate a combined event information frame that includes composite event information, a unique identifier referencing the composite event information, and control commands to coordinate the communication with the observation entities (10), and distributing the combined event information frame within a distribution domain. Furthermore, a road vehicle onboard system is described.
