International standards for transportation systems

The transportation system is one of the most sought after industries in the 21st century. So when this area, despite the introduction of a huge number of innovative technologies, is directly responsible for human health, then a large number of regulatory documents are created specifically for this industry. One of the most demanded types of acts today are ISO international standards. If the transport industry directly or indirectly affects the scope of your activity, the availability of these international documents will allow you to be sure that all possible risks are foreseen by you and the vector of development on an international scale will not be a problem for you. Below we will provide some of the most relevant standards in the transport industry today.

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)

EN ISO 14819-1:2021

The issues of regulating the transfer of information in the 21st century are relevant not only for information technologies, but also for other branches of human activity, one of which is transport systems. To regulate information security issues in this category, such an international standard as EN ISO 14819-1: 2021 was created.

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.

This international document has a huge number of technological characteristics and parameters that make it possible to clearly determine whether this standard is suitable for you or not. If the above technologies are used by you for the main or indirect activity, we strongly recommend that you pay attention to this international standard and think about its mandatory presence in the scientific and technological base of your enterprise.

Electronic fee collection - Test procedures for user and fixed equipment - Part 2: Conformance test for the on-board unit application interface (ISO 14907-2:2021)

EN ISO 14907-2:2021

We have already mentioned more than once about the importance of such a stage as test methods, as well as research and drawing up conclusions by the empirical method. To avoid the negative consequences of incorrect conclusion as a result of testing a certain product, such international documents and standards have been created, such as, for example, EN ISO 14907-2: 2021.

This document describes tests which verify on-board unit (OBU) conformance of functions and data structures implementations, as defined in the implementation conformance statement (ICS) based on ISO 14906 for EFC applications.

This document defines tests for assessing OBU conformance in terms of :

— basic dedicated short-range communication (DSRC) L7 functionality,

— EFC application functions,

— EFC attributes (i.e. EFC application information),

— the addressing procedures of EFC attributes and (hardware) components,

— the EFC transaction model, which defines the common elements and steps of any EFC transaction, and

— the behaviour of the interface so as to support interoperability on an EFC-DSRC application interface level.

After the tests of isolated data items and functions (C.2 to C.4), an example is given for testing a complete EFC transaction (C.3). Although this document defines examples of test cases for DSRC and EFC functionality (see Annex C), it does not intend to specify a complete test suite for a certain implementation. To compose a test suite for a specific EFC implementation, the test cases can be modified and new test cases can be defined and added in order for the conformance test suite to be complete. It can be useful to consider the following when defining a complete test suite:

— small range: “exhaustive testing” of critical interoperability/compatibility features,

— large range: testing of boundaries and random values

— composite types: testing of individual items in sequence or parallel.

This document does not define tests which assess:

— performance,

— robustness, and

— reliability of an implementation.

NOTE 1 ISO 14907-1 defines test procedures that are aimed at assessing performance, robustness and reliability of EFC equipment and systems. NOTE 2 The ISO/IEC 10373 series defines test methods for proximity, vicinity, integrated circuit(s) cards and related devices that can be relevant for OBUs which support such cards.

Annex D provides an informative overview of Japanese on-board equipment (OBE) conformance tests which are based on the ISO 14907 series, in order to illustrate how these can be applied in practice.

This International Standard refers to related documents in the industry and has specific recommendations prescribed for its implementation. If you are interested in building a whole complex in accordance with the latest international requirements, we recommend that you familiarize yourself with all international standards of the transport system industry and select documents that qualitatively complement each other.

Cooperative intelligent transport systems (C-ITS) - Global transport data management (GTDM) framework (ISO/TS 21184:2021)

CEN ISO/TS 21184:2021

International standards created for the transport systems industry can be both global and narrow-profile. Meaning a certain category, this or that document describes both a certain technology and specific mechanisms. One of the most striking examples is the CEN ISO / TS 21184: 2021 standard.

This document specifies a global transport data management (GTDM) framework composed of

— global transport basic data model,

— global transport access control data model,

— global transport function monitor data model, and

— sensor and control network data model

to support data exchange between applications. This document defines standardized data classes in a Global Transport Data Format (GTDF), and the means to manage them. Application and role-based access control to resources in GTDF are specified in accordance with IEEE 1609.2 certificates.

This document specifies GTDM as an ITS-S capability which is an optional feature (ITS-capabilities are specified in ISO 24102-6).

The GT access control (GTAC) data model specifies access permissions to data and function control by defining role-based mechanisms.

The GT function monitor (GTFM) data model specifies a configuration method to generate a flow logic for monitoring purposes, e.g. observing data parameters with respect of a defined limit. The abstract to this document has a number of technological parameters that will allow you to make sure that this particular standard is necessary for you, or it will give you an understanding of the need to make a choice in favor of a more suitable document specifically for your organization. If a large number of technical parameters misleads you, you can follow the link to our website and seek advice from specialists in the field of selection of international standards.

Cooperative intelligent transport systems (C-ITS) - Guidelines on the usage of standards - Part 1: Standardization landscape and releases (ISO/TR 21186-1:2021)

CEN ISO/TR 21186-1:2021

Despite the fact that in most cases international standardization is created to regulate certain categories of human activity in setting up mechanisms, as well as introducing innovative technologies, it should be noted that international documents are also being created that are a kind of clarifying standard for other documents, the so-called guidelines, one of which is CEN ISO / TR 21186-1: 2021.

This document

— describes standardization activities related to C-ITS on a global level by major standard development organizations (SDOs);

— explains the various purposes of deliverables from SDOs and introduces a classification scheme of such documents;

— describes methods on how C-ITS services are presented and performed;

— identifies an approach for C-ITS releases and exemplifies this approach;

— presents a list of standards (Bibliography) with special relevance for C-ITS.

If your organization or business uses international standards regulating transport systems, this standard can significantly simplify the implementation of these documents into an existing structure, explaining certain terms, methods of using other documents, as well as possible misunderstandings that may arise as a result of the interpretation of the terms used.

Public transport - Interoperable fare management system - Part 1: Architecture (ISO 24014-1:2021)

EN ISO 24014-1:2021

When it comes to the regulation of public transport, which is widely used for the movement of people, it is necessary to be aware that this particular category of transport is responsible for human lives, and therefore must necessarily be regulated by regulatory legal acts such as EN ISO 24014-1 : 2021.

This document gives guidelines for the development of multi-operator/multi-service interoperable public surface (including subways) transport fare management systems (IFMSs) on a national and international level.

This document is applicable to bodies in public transport and related services which agree that their systems need to interoperate. This document defines a conceptual framework which is independent of organizational and physical implementation. Any reference within this document to organizational or physical implementation is purely informative.

This document defines a reference functional architecture for IFMSs and establishes the requirements that are relevant for ensuring interoperability between several actors in the context of the use of electronic tickets.

The IFMS includes all the functions involved in the fare management process, such as:

— management of media,

— management of applications,

— management of products,

— security management, and certification, registration, and identification.

This document defines the following main elements: — identification of the different sets of functions in relation to the overall IFMS and services and media from non-transport systems which interact with fare management systems; — a generic model of an IFMS describing the logical and functional architecture and the interfaces within the system, with other IFMSs and with services and media from non-transport systems; — use cases describing the interactions and data flows between the different sets of functions; — security requirements.

In its annexes, this document provides a framework for mobility platforms that integrate fare management and travel information for inter- and multimodal travel (see Annex A). It also elaborates on specific subjects covered in document and offers some national examples with regard to IFMS implementations (see Annex B, Annex C, Annex D and Annex E).

This document does not define:

— the technical aspects of the interface between the medium and the medium access device;

— the data exchanges between the medium and the medium access device;

NOTE The data exchanges between the medium and the medium access device are proposed by other standardization committees.

— the financial aspects of fare management systems (e.g. customer payments, method of payment, settlement, apportionment, reconciliation).

Please note before purchasing this document that it has a certain number of amendments and subcategories, in which it does not apply and to which its recommendations cannot be extended. That is why we advise you to study all its characteristics and parameters in more detail.

Standards are the shortest way for development of the company

International standardization of transport systems has always been relevant even before the creation of such international documents as ISO standards. They took the form of a certain technological base in the form of recommendations for building the entire system. It should be noted once again that transport technologies are primarily responsible for the safety and life of a person, which is why, first of all, when building a company that integrates these technologies or completely focuses on it, it is necessary to minimize all possible risks. If you use the international standards listed above, but from previous years of publication, we recommend that you constantly monitor their updates in order to stay up to date with the latest recommendations and requirements of the modern market.
