International Standards For Transportation Systems
The transport system is one of the most pursued businesses in the 21st century. When this area, despite the introduction of a huge number of advanced technologies, is directly responsible for human health, then a significant number of regulatory records are made specifically for this industry. One of the most demanded types of acts today are ISO international standards. If the transfer industry directly or indirectly impacts the scope of the activity, the availability of these international documents allow you to make certain all probable risks are foreseen by you along with the vector of growth on an global scale won't be a problem for you. Below we will offer some of the most relevant criteria in the transportation industry now.
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 problems of regulating the transfer of information in the 21st century are applicable not only for information technologies, but also for different branches of human activity, one of which is transportation systems. To modulate information security issues in this class, such an global benchmark as EN ISO 14819-1: 2021 has been created.
The ALERT-C protocol is designed to supply largely event-oriented road end-user information messages. This document defines the messages that are presented to the consumer in accord with a set of general requirements. The message management component of the document describes the message management functions of RDS-TMC. User messages are such possibly made known to the end-user, as defined in Clause 5. System messages are of use only to the RDS-TMC terminal, for information management functions. useful international standards info here.
RDS-TMC information comprises both'system information' and'user messages'. System info relates to the TMC service and details the parameters which the terminal should have the ability to discover, identify and decode the TMC information. System information is transmitted in type 3A groups and in kind 8A groups. User messages contain the facts of the traffic occasions; these can use one or more kind 8A groups. Most messages might be transmitted using one type 8A group, however messages with much more detail (e.g. diversion advice) can use up to a total of five, type 8A groups.
The transmission component of the document communicates the messages over-air. The ALERT-C protocol, used by RDS-TMC, has the fundamental approach of organizing 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 features and parameters that make it possible to clearly determine whether this standard is acceptable for you or not. In the event the aforementioned technologies are utilized by you for the indirect or main activity, we strongly advise that you listen to this international standard and think about its mandatory presence in the scientific and technological base of your business.
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 significance of such a stage as test methods, as well as research and drawing conclusions from the empirical method. To avoid the negative consequences of erroneous conclusion as a consequence of analyzing a specific product, such international documents and standards have been created, including, 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 to get EFC applications.
This record defines tests for analyzing OBU conformance in terms of:
-- basic dedicated short-range communication (DSRC) L7 functionality,
-- EFC application functions,
-- EFC attributes (i.e. EFC application data ),
-- the addressing processes of EFC attributes and (hardware) components,
-- the EFC transaction model, that defines the common components and steps of any EFC trade, and
-- the behavior of the interface in order to encourage interoperability within an EFC-DSRC application interface level.
After the evaluations of isolated data items and works (C.two to C.4), an illustration is given for analyzing a complete EFC transaction (C.3). Although this document defines illustrations of test cases for DSRC and EFC functionality (see Annex C), it does not mean to specify an entire test suite for a certain implementation. To write a test suite for a specific EFC implementation, the test instances can be modified and new test instances could be defined and added for the conformance test package to be complete. It can be useful to consider the following when defining an entire test package:
-- small range:"exhaustive testing" of crucial interoperability/compatibility features,
-- big variety: testing of bounds and random values, and
-- mix types: testing of individual items in parallel or sequence.
This document does not define tests which check:
-- performance,
-- robustness, and
-- reliability of an implementation.
NOTE 1 ISO 14907-1 defines evaluation processes that are targeted at analyzing functionality, robustness and dependability of EFC systems and equipment.
NOTE 2 The ISO/IEC 10373 series defines test methods for proximity, vicinity, integrated circuit(s) cards and related devices which could be relevant for OBUs that support such cards.
Annex D gives an educational summary of Japanese onboard gear (OBE) conformance tests that are based on the ISO 14907 series, so as to illustrate how these may be implemented in practice. This International Standard describes related records in the business and has specific recommendations prescribed for its implementation. If you are interested in building a whole complex with regard to the latest international demands, we suggest that you familiarize yourself with all international standards of this transportation system industry and choose documents that qualitatively match every other.
