International Standards For Transportation Systems
The transport system is one of the most sought after industries in the 21st century. When this area, despite the introduction of a huge number of advanced technologies, is responsible for human health, then a significant number of regulatory records are made especially for this business. One of the most demanded forms of acts today are ISO international standards. If the transfer industry directly or indirectly affects the scope of your activity, the access to these international documents will allow you to make sure all probable risks are foreseen by you and the vector of development on an international scale will not be troublesome for you. Below we will offer a number of the most important standards in the transportation 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 just for information technologies, but also for different branches of human activity, one of which will be transport systems. To regulate information security problems within this category, such an international benchmark as EN ISO 14819-1: 2021 was created.

The ALERT-C protocol is intended to provide largely event-oriented road end-user information messages. This document defines the messages that are presented to the user in accordance with a set of general requirements. It defines the message structure and material and its presentation to the end-user. The message management component of this document clarifies the message management functions of RDS-TMC. The ALERT-C protocol distinguishes between user messages and system messages. User messages are such potentially made known to the end-user, as described in Clause 5. System messages are of use only to the RDS-TMC terminal, for information management functions. excellent international standards recommendations here.

RDS-TMC information includes both'system info' and'user messages'. System info relates to the TMC support and details the parameters that the terminal should have the ability to find, identify and decode the TMC data. System information is transmitted in form 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 with one kind 8A group, however messages with much more detail (e.g. diversion information ) can use up to a total of five, type 8A groups.

The transmission component of the 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 includes all event descriptions, is explained in ISO 14819-2. This international record has a massive number of technical characteristics and parameters that make it possible to clearly determine whether this standard is acceptable for you or not. If the above technologies are utilized by you for the indirect or main action, we strongly advise that you pay attention to the international standard and think about its compulsory 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've already cited more than once about the importance of such a point as evaluation procedures, as well as research and drawing up conclusions by the empirical method. To prevent the negative effects of incorrect conclusion as a consequence of testing a specific solution, such international documents and standards are 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 described in the implementation conformance statement (ICS) according to ISO 14906 to get EFC applications.

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

-- basic committed short-range communication (DSRC) L7 functionality,
-- EFC application works,
-- EFC attributes (i.e. EFC application data ),
-- the addressing procedures of EFC attributes and (hardware) components,
-- the EFC transaction model, that defines the common elements and measures of any EFC transaction, and
-- the behaviour of the interface in order to encourage interoperability on an EFC-DSRC application interface level.

After the tests of isolated data items and works (C.two to C.4), an example is given for analyzing a complete EFC trade (C.3). Although this document defines illustrations of test cases for DSRC and EFC performance (see Annex C), it does not intend to specify an entire test suite for some implementation. To write a test suite for a particular EFC execution, the test cases can be altered and new test instances could be defined and included in order for the conformance test suite to be finish. It may be useful to consider the following when defining an entire test package:

-- little range:"comprehensive testing" of critical interoperability/compatibility attributes,
-- large variety: testing of bounds and arbitrary values, and
-- composite types: testing of individual items in sequence or parallel.

This document Doesn't define tests which assess:
-- functionality,
-- robustness, and
-- reliability of an execution.

NOTE 1 ISO 14907-1 defines evaluation processes that are aimed at analyzing functionality, robustness and reliability of EFC equipment and systems.



Annex D provides an educational summary of Japanese on-board equipment (OBE) conformance tests which are based on the ISO 14907 series, in order to exemplify how these can be applied in practice. This International Standard describes related documents in the industry and has specific recommendations prescribed for its implementation. If you're interested in building a whole complicated in accordance with the most recent international requirements, we suggest that you familiarize yourself with all worldwide standards of this transportation system industry and select files that qualitatively complement each other.
