What is ISO 14813-5 about?
An intelligent transport system (ITS) reference architecture is a tool that describes how an ITS delivers one or more ITS services.
ISO 14813-5 includes a high-level description of the major elements and the interconnections among them that are needed for the service(s) to be provided to stakeholders.
ISO 14813-5 provides the framework around which the interfaces, specifications, and detailed ITS designs can be standardized within ITS standards.
By contrast, ITS standards are often focused on design details. While the development of these standards may be initiated by a single ITS user need, they are often (and properly) written in a generic format that allows for application in a broad array of contexts. However, this can present a challenge to the reader in understanding the original purpose of a standard and whether the standard is intended for other environments.
ISO 14813-5 defines documentation rules for standards that define interfaces between or among system elements of an ITS reference architecture. This includes:
- Requirements for documenting aspects of the ITS reference architecture
- Terminology to be used when documenting or referencing aspects of the ITS reference architecture
Who is ISO 14813-5 for?
ISO 14813-5 on Intelligent transport systems - Reference model architecture(s) for the ITS sector is useful for:
- Traffic Regulation Authorities
- ITS department
- Public who has vehicle
- Commercial transport and logistic vehicle users
Why should you use ISO 14813-5?
Intelligent transport systems (ITS) are systems deployed in transportation environments to improve both the driving experience and the safety and security of drivers, passengers, and pedestrians. ITS can also assist in the labor, energy, environmental, and cost-efficiency of transportation systems.
ISO 14813-5 offers guidance related to most ITS and their architecture that involves the collection, use, and exchange of information/data within and between software systems which affect or control the behavior of physical equipment in order to provide a service to the actors involved in, or interacting with, the transport sector.
ITS services are developing and changing rapidly and have to make provision not only for interaction with other services, but with migration from one technology generation to later iterations. In order to support this and to obtain compatibility and/or interoperability and to eliminate contention, the systems need to co-exist and operate within a known and supportive architectural framework.
ISO 14813-5 is designed to aid these objectives and to enable maximum interoperability, efficiency, and migration capability by defining an explicit process for describing ITS reference architectures for use within ITS International Standards using an explicit process.
A second function of this document is to provide consistent terminology to be used in describing architectural aspects of ITS standards and provide a consistent form for describing an ITS reference architecture in standards in the ITS sector.
What’s changed since the last update?
BS ISO 14813-5:2020 supersedes BS ISO 148135:2010. BS ISO 14813-5:2020 includes some technical changes with respect to BS ISO 148135:2010. These include:
- Clarifies the scope of standards to which ISO 14813-5 applies
- Clarifies and renames the types of architectures used within the ITS community and their relationships with each other
- Removes details related to planning and deployment architectures
- Clarifies requirements and provides examples of text that should be included within ITS interface standards.
