SIST-TS CEN ISO/TS 17429:2017

Intelligent transport systems - Cooperative ITS - ITS station facilities for the transfer of information between ITS stations (ISO/TS 17429:2017)

This international standard falls into the Cooperative ITS set of standards based onthe ITS station reference architecture. Typically, raw and dense information transmitted by ITS stations (e.g. CAM and DENM broadcast from vehicles for road safety purposes) is collected by other ITS stations (presumably the roadside infrastructure ). This information must be processed and transferred in a standardized way between ITS stations (presumably between the roadside infrastructure and traffic control centres) so that it could be used for traffic management purposes by road operators. The processing of this information could also lead to improved road safety, improved road efficiency and reduced
greenhouse gas emissions. The purpose of this international standard is to specify the profiles for processing the collected information at the receiving ITS station and transferring the processed data to other ITS stations for applications related to transport infrastructure management, control and guidance. This standard will thus:
- select the services, functions and expected results,
- select the roles and responsibilities of all the involved actors,
- select involved functions and SAPs (Service Access Point) of the ITS station
reference architecture,
- characterize how the collected data is pre-processed by the receiving ITS station,
- select the content of the information to be exchanged between the various
actors,
- characterize the level of performance (best effort or real-time, etc.), confidence
and security (authentication, encryption, etc.) for the transfer of the information,
- select the means by which the processed information is transferred (securely)
between the different actors.

Inteligentni transportni sistemi - Kooperativni sistem (ITS) - Objekti postaj ITS za prenos podatkov med postajami ITS (ISO/TS 17429:2017)

Ta mednarodni standard je del skupine standardov o kooperativnem sistemu ITS, ki temelji na referenčni arhitekturi postaje ITS. Neobdelane in goste informacije, ki jih oddajajo postaje ITS (npr. oddajanje CAM in DENM vozil za namene varnosti v cestnem prometu) običajno zbirajo druge postaje ITS (domnevno cestna infrastruktura). Te informacije je treba obdelati in prenesti na standardiziran način med postajami ITS (načeloma med cestno infrastrukturo in prometnimi nadzornimi centri), tako da jih lahko upravljavci cest uporabljajo za namene upravljanja prometa. Obdelava teh informacij bi lahko privedla tudi do izboljšane varnosti v cestnem prometu, izboljšane učinkovitosti cest in zmanjšanja emisij toplogrednih plinov. Namen tega mednarodnega standarda je določiti profile za obdelavo zbranih informacij sprejemne postaje ITS in prenos obdelanih podatkov drugim postajam ITS za uporabe, povezane z upravljanjem, nadzorom in vodenjem prometne infrastrukture. Ta standard bo:
– določil storitve, funkcije in pričakovane rezultate,
– določil vloge in odgovornosti vseh vpletenih akterjev,
– določil povezane funkcije in vstopne točke storitve (SAP) referenčne arhitekture postaje ITS,
– opredelil, kako sprejemna postaja ITS predhodno obdeluje zbrane podatke,
– določil vsebino informacij, ki se izmenjujejo med različnimi akterji,
– opredelil raven zmogljivosti (prizadevanje za najboljšo zmogljivost ali prenos v realnem času itd.), zaupanja in varnosti (preverjanje pristnosti, šifriranje itd.) za prenos informacij,
– določil način, na katerega se obdelane informacije (varno) prenašajo med različne akterje.

Introduction
ITS station units compliant with the ITS station reference architecture specified in ISO 21217 may
engage in Cooperative ITS (C-ITS) activities involving data exchanges between ITS stations in a variety
of roles. Such data exchanges include, but are not limited to:
— data collected by the roadside infrastructure and transmitted to traffic control centers, possibly
after aggregation,
— roadside equipment configured from the control centers to process a given set of data or issue
messages to vehicles,
— roadside events reported to control centers, and
— broadcast transmission of vehicle status and event messages (e.g. CAM) to nearby ITS stations.
An example of an ITS station unit engaged in a C-ITS activity is a roadside ITS station unit collecting
traffic-related information generated by road sensors and/or by vehicle ITS station units. The collected
data can often serve other purposes than the originally intended one. For example, the cooperative
awareness message (CAM) from the ETSI C-ITS message set generated for traffic-safety applications
can be collected by roadside ITS station units for exploitation by traffic efficiency applications in traffic
control centers (e.g. central ITS stations). The same information is thus used to improve road safety, as
well as traffic efficiency and also to reduce greenhouse gas emissions.
The exploitation of such exchanges for purposes not initially intended is made possible once this
exchange of information is performed in a standardized way through an ITS station facilities layer
that is able to recognize messages from specific message sets (e.g. DATEX II, TPEG, C-ITS message sets)
with data according to data object specifications from data dictionaries (e.g. the common ETSI data
dictionary) and to forward them to applications which have an interest therein and have subscribed to
the delivery of such message(s) and data. A Communication Profile Handler (CPH), a Facilities Services
Handler (FSH) and a Content Subscription Handler (CSH) are defined in this Technical Specification to
serve this purpose.
Outside of this Technical Specification, the commonly used term “message set” is used to indicate a
collection of “messages” used in the exchange of information between peer ITS station units (see
ISO/TS 17419). These messages are composed of structures sometime referred to as “data frames”
and/or “data objects” which are in turn composed of objects called “data elements” (see SAE J2735).
Herein, a slightly different lexicon is adopted. The term “data dictionary” is used to indicate a
collection of “messages”, including “data object” from which the messages are composed. Thus, herein,
“data objects” are synonymous with “data frames” and “data elements”. However, in this Technical
Specification, the terms are used with the precise meaning to distinguish messages and data objects
from which messages are constructed.
The functionalities specified in this Technical Specification include a Communication Profile
Handler (CPH), a Facilities Services Handler (FSH), and a Content Subscription Handler (CSH). These
functionalities are intended to enable, and be invoked by, technology-agnostic ITS applications and to
facilitate the deployment of C-ITS applications that share information. In particular, these functionalities
allow an application to
— specify a set of facilities layer services to be applied to its data units (ADUs),
— allow ITS station management to select the optimum communication profile (as a function of time)
for any or all of its data flows, and
— publish information to and subscribe to information from a central repository (the CSH) in a
standardized way that enables sharing of information between applications (the definition of C-ITS).
These functionalities provide a toolkit facilitating the specification of standards and the development
of ITS applications [e.g. In-Vehicle Signage (ISO/TS 17425), Contextual Speed (ISO/TS 17426), Point of

Intelligent transport systems — Cooperative ITS — ITS
station facilities for the transfer of information between
ITS stations
1 Scope
This Technical Specification specifies generic mechanisms enabling the exchange of information
between ITS stations for applications related to Intelligent Transport Systems. It complies with the
ITS station reference architecture (ISO 21217) and defines the following ITS station facilities layer
functionalities:
— Communication Profile Handler (CPH);
— Content Subscription Handler (CSH);
— Facilities Services Handler (FSH).
These functionalities are used by ITS-S application processes (ITS-S-AP) to communicate with other
ITS-S application processes and share information. These functionalities describe
— how lower-layer communication services assigned to a given data flow are applied to the service
data units at the various layers in the communication protocol stack (CPH, see 6.2.3),
— how content from data dictionaries can be published and subscribed to by ITS-S application
processes (CSH, see 6.2.5),
— how well-known ITS station facilities layer and management services can be applied to application
process data units (FSH, see 6.2.4), relieving (ITS-S) application processes from having to implement
these services on their own,
— how service access points (SAP) primitives specified in ISO 24102-3 are used,
— service primitives for the exchange of information between ITS-S application processes and the ITS
station facilities layer (FA-SAP), and
— a set of communication requirements and objectives (profiles) using the methods defined in
ISO/TS 17423 to select the level of performance (best effort or real-time, etc.), confidence and
security (authentication, encryption, etc.) for information exchange between ITS stations, such as
data provision, event notification, roadside configuration, map update.
