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.
