Intelligent transport systems - Cooperative ITS - Using V2I and I2V communications for applications related to signalized intersections (ISO/TS 19091:2019)

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.

Inteligentni transportni sistemi (ITS) - Kooperativni ITS - Uporaba komunikacij V2I in I2V za aplikacije v zvezi s signali v križiščih (ISO/TS 19091:2019)

Ta dokument opredeljuje sporočilo, podatkovne strukture in podatkovne elemente za podporo izmenjav med obcestno opremo ter vozili za obravnavo aplikacij za izboljšanje varnosti, mobilnosti in okoljske učinkovitosti. Za namen preverjanja, ali bodo opredeljena sporočila ustrezala tem aplikacijam, je bil uporabljen postopek inženiringa sistemov, ki spremlja primere uporabe glede na zahteve ter zahteve glede na sporočila in podatkovne koncepte.
Ta dokument obsega en sam dokument, ki vsebuje osnovno specifikacijo in nabor prilog. Osnovna specifikacija navaja izpeljane zahteve po informacijah (označene kot informativne) in sklice na druge standarde za definicije sporočil, če so na voljo. Priloga A vsebuje opise primerov uporabe, ki jih obravnava ta dokument. Prilogi B in C vsebujeta matrike sledljivosti, ki primere uporabe povezujejo z zahtevami ter zahteve z definicijami sporočil (tj. okviri podatkov in podatkovnimi elementi).
V naslednjih prilogah so navedene osnovne zahteve za sporočila in specifične zahteve za aplikacije (matrika sledljivosti zahtev), ki ustrezajo sporočilu ter podatkovnim konceptom, ki jih je treba implementirati. Implementacija v tem dokumentu obsega osnovo in dodatno skupino razširitev.
Podrobnosti o zahtevah glede informacij, razen za sporočila SPaT, MAP, SSM in SRM, so na voljo v
drugih mednarodnih standardih. Cilj tega dokumenta je določiti podrobnosti o sporočilih SPaT, MAP, SSM in SRM, ki podpirajo primere uporabe, opredeljene v tem dokumentu. Sprejetje teh sporočil se po regijah razlikuje in njihovo sprejemanje je lahko dolgotrajno.
Ta dokument zajema vmesnik med obcestno opremo in vozili. Aplikacije, njihovi notranji algoritmi in logična porazdelitev funkcionalnosti aplikacij v kateri koli specifični sistemski arhitekturi so zunaj področja uporabe tega dokumenta.
