1 Scope
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.
