This document defines the message, data structures, and data elements to support exchanges between
the roadside equipment and vehicles to address applications to improve safety, mobility and
environmental efficiency. In order to verify that the defined messages will satisfy these applications, a
systems engineering process has been employed that traces use cases to requirements and
requirements to messages and data concepts.
This document consists of a single document that contains the base specification and a series of
annexes. The base specification lists the derived information requirements (labelled informative) and
references to other standards for message definitions where available. Annex A contains descriptions of
the use cases addressed by this document. Annexes B and C contain traceability matrices that relate use
cases to requirements and requirements to the message definitions (i.e. data frames and data elements).
The next annexes list the base message requirements and application-oriented specific requirements
(requirements traceability matrix) that map to the message and data concepts to be implemented. As
such, an implementation consists of the base plus an additional group of extensions within this
document.
Details on information requirements, for other than SPaT, MAP, SSM, and SRM messages are provided in
other International Standards. The focus of this document is to specify the details of the SPaT, MAP,
SSM, and SRM supporting the use cases defined in this document. Adoption of these messages varies by
region and their adoption can occur over a significant time period.
This document covers the interface between roadside equipment and vehicles. Applications, their
internal algorithms, and the logical distribution of application functionality over any specific system
architecture are outside the scope of this document.
