This document identifies traffic management interfaces between central stations and specifies related ITS communication profiles enabling standardized data exchange over these communication interfaces, applicable for a variety of platforms including ITS station units (ITS-SUs) compliant with ISO 21217:2014. This document further specifies requirements on encoding of data. These traffic management interfaces enable — the provision of appropriate and relevant traffic information, e.g. congestion and travel times, to users across a variety of platforms; — exchange of data such as: — network performance data, e.g. traffic conditions, travel times, and — planned and unplanned events and incidents, e.g. — roadworks, — closures of roads, bridges, and tunnels, — bad weather, — road surface conditions; This document recognizes specifications from DATEX II in order to avoid duplicate specifications. In doing so, this document aligns with existing products of CEN/TC 278/WG 8 and the additional work being undertaken within the DATEX community.
