Intelligent transport systems - Traffic and travel information messages via traffic message coding - Part 1: Coding protocol for Radio Data System - Traffic Message Channel (RDS-TMC) using ALERT-C (ISO 14819-1:2021)

Intelligent transport systems - Traffic and travel information messages via traffic message coding - Part 1: Coding protocol for Radio Data System - Traffic Message Channel (RDS-TMC) using ALERT-C (ISO 14819-1:2021)

The ALERT-C protocol is designed to provide mostly event-oriented road end-user information messages.
This document specifies the messages which are presented to the user in accordance with a set of general requirements. It defines the message structure and content and its presentation to the end-user.
The message management component of this document describes the message management functions of RDS-TMC. The ALERT-C protocol distinguishes between user messages and system messages. User messages are those potentially made known to the end-user, as defined in Clause 5. System messages are of use only to the RDS-TMC terminal, for message management purposes.
RDS-TMC information comprises both ?system information' and ?user messages'. System information relates to the TMC service and details the parameters that the terminal needs to be able to find, identify and decode the TMC information. System information is transmitted in type 3A groups and in type 8A groups.
User messages contain the details of the traffic events; these may use one or more type 8A groups. Most messages may be transmitted using a single type 8A group, however messages with more detail (e.g. diversion advice) may use up to a total of five, type 8A groups.
The transmission component of this document conveys the messages over-air. The ALERT-C protocol, used by RDS-TMC, has the fundamental approach of aiming to code most messages entirely within a single RDS group.
The ALERT-C Event List, which contains all event descriptions, is described in ISO 14819‑2.

Systèmes de transport intelligents - Informations sur le trafic et les déplacements via le codage de messages sur le trafic - Partie 1: Protocole de codage pour le système de radiodiffusion de données - canal de messages d'informations sur le trafic (RDS-TMC) avec Alert-C (ISO 14819-1:2021)

Le protocole Alert-C est conçu pour fournir des messages d'information du conducteur orientés événements pour la plupart d'entre eux. Il est prévu de définir ultérieurement de nombreuses extensions de protocole et, de fait, quelques messages d'information de guidage routier orientés état ont été inclus.
Le présent document spécifie les messages qui sont présentés à l'utilisateur conformément à un ensemble d'exigences générales. Elle définit la structure et le contenu des messages ainsi que leur présentation à l'utilisateur final.
La composante de gestion de messages du présent document traite des fonctions de gestion des messages du RDS-TMC. Le protocole Alert-C opère une distinction entre les messages utilisateur et les messages système. Les messages utilisateur sont ceux qui sont potentiellement portés à la connaissance de l'utilisateur final, comme défini à l'Article 5. Les messages système ne sont utiles qu'au terminal RDS‑TMC, pour les besoins de la gestion des messages.
L'information RDS-TMC comprend à la fois des messages d'information système et des messages utilisateur. L'information système se rapporte au service TMC et détaille les paramètres dont le terminal a besoin pour trouver, identifier et décoder l'information TMC. L'information système est transmise dans les groupes de type 3A et les groupes de type 8A.
Les messages utilisateur contiennent les détails des événements liés au trafic. Ils peuvent utiliser un ou plusieurs groupes de type 8A. La plupart des messages peuvent être émis en utilisant un groupe 8A unique, cependant des messages comportant plus de détails (par exemple un conseil de déviation) peuvent utiliser jusqu'à cinq groupes de type 8A.
La section du présent document relative à la transmission opère la diffusion des messages par voie hertzienne. Le protocole Alert-C, utilisé en RDS-TMC, fait appel à l'approche fondamentale visant à coder la plupart des messages avec un seul groupe RDS.
La liste d'événements Alert-C qui contient la description de tous les événements est décrite dans l'ISO 14819‑2.

Electronic fee collection - Localization augmentation communication for autonomous systems (ISO 13141:2024)
oSIST prEN ISO 13141:2023

This document establishes requirements for short-range communication for the purposes of augmenting the localization in autonomous electronic fee collection (EFC) systems. Localization augmentation serves to inform on-board equipment (OBE) about geographical location and the identification of a charge object. This document specifies the provision of location and heading information and security means to protect against the manipulation of the OBE with false RSE.
The localization augmentation communication (LAC) takes place between an OBE in a vehicle and fixed RSE. This document is applicable to OBE in an autonomous mode of operation.
This document specifies attributes and functions for the purpose of localization augmentation, by making use of the dedicated short-range communications (DSRC) communication services provided by DSRC Layer 7, and makes these LAC attributes and functions available to the LAC applications at the RSE and the OBE. Attributes and functions are specified on the level of application data units (ADUs; see Figure 1).
As depicted in Figure 1, this document is applicable to:
—     the application interface definition between OBE and RSE;
—     the interface to the DSRC application layer, as specified in ISO 15628 and EN 12834;
—     the use of the DSRC stack.
The LAC is suitable for a range of short-range communication media. This document provides specific definitions regarding the CEN-DSRC stack as specified in EN 15509. Annexes C, D, E and H provide for the use of the Italian DSRC as specified in ETSI/ES 200 674-1, ISO CALM IR ARIB DSRC and WAVE DSRC.
This document contains a protocol implementation conformance statement (PICS) proforma in Annex B and transaction examples in Annex F. Annex G highlights how to use this document for the European Electronic Toll Service (EETS).
Test specifications are not within the scope of this document.

Electronic fee collection - Compliance check communication for autonomous systems (ISO 12813:2024)
SIST EN ISO 12813:2024

This document specifies requirements for short-range communication for the purposes of compliance checking in autonomous electronic fee collecting systems. Compliance checking communication (CCC) takes place between a road vehicle's on-board equipment (OBE) and an interrogator [fixed and mobile roadside equipment (RSE) or hand-held unit] and serves to establish whether the data that are delivered by the OBE correctly reflect the road usage of the corresponding vehicle according to the rules of the pertinent toll regime.
The operator of the compliance checking interrogator is assumed to be part of the toll charging role as defined in ISO 17573-1. The CCC permits identification of the OBE, vehicle and contract, and verification of whether the driver has fulfilled their obligations and the checking status and performance of the OBE. The CCC reads, but does not write, OBE data.
This document is applicable to OBE in an autonomous mode of operation. It is not applicable to compliance checking in dedicated short-range communication (DSRC)-based charging systems.
It specifies data syntax and semantics, but not a communication sequence. All the attributes specified herein are required in any OBE claimed to be compliant with this document, even if some values are set to “not specified” in cases where a certain functionality is not present in an OBE. The interrogator is free to choose which attributes are read in the data retrieval phase, as well as the sequence in which they are read. In order to achieve compatibility with existing systems, the communication makes use of the attributes specified in ISO 17573-3 wherever useful.
The CCC is suitable for a range of short-range communication media. Specific definitions are given for the CEN-DSRC as specified in EN 15509, as well as for the use of ISO CALM IR, the Italian DSRC as specified in ETSI ES 200 674-1, ARIB DSRC, and WAVE DSRC as alternatives to the CEN-DSRC. The attributes and functions specified are for compliance checking by means of the DSRC communication services provided by DSRC application layer, with the CCC attributes and functions made available to the CCC applications at the RSE and OBE. The attributes and functions are specified on the level of application data units (ADUs).
The definition of the CCC includes:
—     the application interface between OBE and RSE (as depicted in Figure 2);
—     use of the generic DSRC application layer as specified in ISO 15628 and EN 12834;
—     CCC data type specifications given in Annex A;
—     a protocol implementation conformance statement (PICS) proforma is given in Annex B;
—     use of the CEN-DSRC stack as specified in EN 15509, or other equivalent DSRC stacks as described in Annex C, Annex D, Annex E and Annex F;
—     security services for mutual authentication of the communication partners and for signing of data (see Annex H);
In addition, an example CCC transaction is presented in Annex G and Annex I highlights how to use this document for the European Electronic Toll Service (EETS).
Test specifications are not within the scope of this document.

Intelligent transport systems - eSafety - eCall HLAP in hybrid circuit switched/packet switched network environments
SIST EN 17905:2024

In respect of 112-eCall (pan-European eCall) (operating requirements defined in EN 16072), this document defines the additional high level application protocols, procedures and processes required to provide the eCall service whilst there are still both circuit switched and packet switched wireless communication networks in operation.
NOTE    The objective of implementing the pan-European in-vehicle emergency call system (eCall) is to automate the notification of a traffic accident, wherever in Europe, with the same technical standards and the same quality of services objectives by using a PLMN (such as ETSI prime medium) which supports the European harmonized 112/E112 emergency number (TS12 ETSI TS 122 003 or IMS packet switched network) and to provide a means of manually triggering the notification of an emergency incident.

This document specifies the syntax and semantics of data objects in the field of electronic fee collection (EFC). The definitions of data types and assignment of semantics are provided in accordance with the abstract syntax notation one (ASN.1) technique, as specified in ISO/IEC 8824-1. This document defines:
—     ASN.1 (data) types within the fields of EFC;
—     ASN.1 (data) types of a more general use that are used more specifically in standards related to EFC.
This document does not seek to define ASN.1 (data) types that are primarily related to other fields that operate in conjunction with EFC, such as cooperative intelligent transport systems (C-ITS), the financial sector, etc.

Intelligent transport systems - ESafety - eCall high level application requirements (HLAP) using GSM/UMTS circuit switched networks
SIST EN 16062:2023

In respect of pan-European eCall (operating requirements defined in EN 16072), this document defines the high-level application protocols, procedures and processes required to provide the eCall service using a TS12 emergency call over a circuit-switched mobile communications network.
NOTE 1   The objective of implementing the pan-European in-vehicle emergency call system (eCall) is to automate the notification of a traffic accident, wherever in Europe, with the same technical standards and the same quality of services objectives by using a PLMN (such as ETSI prime medium) which supports the European harmonized 112/E112 emergency number (TS12 ETSI TS 122 003) and to provide a means of manually triggering the notification of an emergency incident.
NOTE 2   HLAP requirements for third-party services supporting eCall can be found in EN 16102, and have been developed in conjunction with the development of this work item, and is consistent in respect of the interface to the PSAP. This deliverable makes reference to those provisions but does not duplicate them.

Intelligent transport systems - eSafety - eCall additional data concept for equipment limitations
SIST EN 17870:2023

This document defines an additional data concept that can be transferred as the ‘optional additional data’ part of an eCall MSD, as defined in EN 15722, that can be transferred from a vehicle to a PSAP in the event of a crash or emergency via an eCall communication session.
The purpose of this document is to provide means to notify the PSAP of any limitations to the sending equipment that are endorsed by other standards, but not (immediately) apparent to the receiver. Lack of knowledge about these limitations can hamper the emergency process. This document describes an additional data concept which facilitates the inclusion of information about such limitations in a consistent and usable matter.
This document can be seen as an addendum to EN 15722; it contains as little redundancy as possible.
NOTE 1   The communications media protocols and methods for the transmission of the eCall message are not specified in this document.
NOTE 2   Additional data concepts can also be transferred, and it is advised to register any such data concepts using a data registry as defined in EN ISO 24978 [1]. See www.esafetydata.com for an example.

Electronic fee collection - Application interface definition for dedicated short-range communication (ISO 14906:2022)
SIST EN ISO 14906:2023

This document specifies the application interface in the context of electronic fee collection (EFC) systems using dedicated short-range communication (DSRC).
The EFC application interface is the EFC application process interface to the DSRC application layer, as can be seen in Figure 1. This document comprises specifications of:
—    EFC attributes (i.e. EFC application information) that can also be used for other applications and/or interfaces;
—    the addressing procedures of EFC attributes and (hardware) components (e.g. integrated circuit(s) card);
—    EFC application functions, i.e. further qualification of actions by definitions of the concerned services, assignment of associated ActionType values, and content and meaning of action parameters;
—    the EFC transaction model, which defines the common elements and steps of any EFC transaction;
—    the behaviour of the interface so as to ensure interoperability on an EFC-DSRC application interface level.
This is an interface standard, adhering to the open systems interconnection (OSI) philosophy (see ISO/IEC 7498-1), and it is as such not primarily concerned with the implementation choices to be realized at either side of the interface.
This document provides security-specific functionality as place holders (data and functions) to enable the implementation of secure EFC transactions. Yet the specification of the security policy (including specific security algorithms and key management) remains at the discretion and under the control of the EFC operator, and hence is outside the scope of this document.

Intelligent transport systems - Geographic Data Files (GDF) GDF5.1 - Part 2: Map data used in automated driving systems, Cooperative ITS, and multi-modal transport (ISO 20524-2:2020)
SIST EN ISO 20524-2:2023

This document specifies the conceptual and logical data model in addition to the physical encoding formats for geographic databases for Intelligent Transport Systems (ITS) applications and services. This document includes a specification of potential contents of such databases (data dictionaries for Features, Attributes and Relationships), a specification of how these contents are to be represented, and how relevant information about the database itself can be specified (metadata). This document further defines map data used in automated driving systems, Cooperative-ITS, and Multi-modal transport.
The focus of this document is firstly on emerging ITS applications and services, such as Cooperative-ITS and automated driving systems, and it emphasizes road, lane and relevant information on road and lane. However, ITS applications and services also require other information in addition to road and road-related information, which are provided as external databases to connect with GDF and to complement each other. Highly defined public transport databases, for instance, are indispensable in multi-modal transport applications and services in particular. Thus, this document focuses secondly on an expansion of the specification to connect with externally existing databases. It is particularly designed to connect a Transmodel (EN 12896-1 and EN 12896-2) conformant public transport database.
Typical ITS applications and services targeted by this document are in-vehicle or portable navigation systems, traffic management centres, or services linked with road management systems, including public transport systems.
The conceptual data model specified here has a broader focus than ITS applications and services. It is application independent, allowing for future harmonization of this model with other geographic database standards.
