UNE-CEN ISO/TS 19321:2024

This document specifies the in-vehicle information (IVI) data structures that are required by differentintelligent transport system (ITS) services for exchanging information between ITS stations (ITS-S).A general, extensible data structure is specified, which is split into structures called containers toaccommodate current-day information. Transmitted information includes IVI such as contextual speed,road works warnings, vehicle restrictions, lane restrictions, road hazard warnings, location-based servicesand re-routing. The information in the containers is organized in sub-structures called data frames and dataelements, which are described in terms of their content and syntax.The data structures are specified as communications-agnostic. This document does not provide thecommunication protocols. This document provides scenarios for usage of the data structure, e.g. in case ofreal time, short-range communications.
