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.Cross References:ISO 22951ETSI/TS 102 894-2 V1.3.1SAE J2735:2016ARIB STD-T109ISO 26684IEEE 610.12:1990ETSI/TS 103 301NTCIP 1211SAE J2945ISO/TR 17465-1ISO/IEC IEEE 24765ISO 12353-1ISO/TS 20452ISO/IEC 26514ISO/IEEE 11073-10201NMEA 0183:2008SAE J3067:2014All current amendments available at time of purchase are included with the purchase of this document.
