What is ISO 17438-4- Intelligent transport systems about?
ISO 17438-4 defines detailed use cases, requirements and message specifications for supporting indoor navigation functionality between a personal/vehicle (P/V) ITS station and a central ITS station.
ISO 17438-4 defines:
- Clusters of use cases based on processing flows for indoor navigation between a P/V ITS station and a central ITS station
- Detailed use cases derived from the clusters of use cases for indoor navigation
- Message specifications to support some of the detailed use cases. The message specifications include mandatory, conditional, and optional elements
ISO 17438-4 is applicable to the core flow for the navigational functionality in indoor space. The following issues which are adjunctive but essential for commercial navigation services are:
- Authorized and authenticated access of users and services, including security
- Payment
- Preparation of indoor data which are necessary for indoor navigation
- Detailed data formats for indoor navigation data, including indoor maps and indoor positioning references (these form a part of ISO 17438‑21) and ISO 17438‑32))
- How to transfer and share data required for indoor navigation between a roadside ITS station and a central ITS station, i.e. low-level communication protocols
- Other issues dependent on the implementation of an instance of indoor navigation, e.g. indoor-outdoor seamless navigation
ISO 17438-4 uses the XML and Data eXchange Message (DXM) format defined in ISO 131842 to encode defined messages.
Who is ISO 17438-4 - Intelligent transport systems for?
ISO 17438-4 on Intelligent transport systems is useful for:
- Transport vehicles
- ITS station
- Traffic regulation authorities
Why should you use ISO 17438-4 - Intelligent transport systems ?
With the spread of nomadic and mobile devices such as smartphones and the rapid expansion of indoor spaces, many of the services and facilities related to the transport system have become accessible to indoor spaces. Consequently, navigation in indoor space is considered a new killer application in the transport industry.
The objective of ISO 17438-4 is to provide helpful message specifications required for indoor navigation functionality.
ISO 17438-4 is intended to be used by designers, developers and providers of indoor navigation services.
ISO 17438-4 defines use cases, requirements and message specifications for supporting indoor navigation in intelligent transport systems. When implemented, this document will:
- Provide developers and designers with concepts and appropriate information to implement indoor navigation service
- Provide developers and designers with interoperable ways to use indoor navigation data from various sources for indoor navigation
- Enable users to be provided with indoor navigation
- Provide developers and designers with an extendable base for indoor navigation
