ISO 20524-2 specifies the conceptual and logical data model in addition to the physical encoding formats for geographic databases for Intelligent Transport Systems (ITS) applications and services.
ISO 20524-2 includes a specification of potential contents of such databases (data dictionaries for Features, Attributes, and Relationships), a specification of how these contents are to be represented, and how relevant information about the database itself can be specified (metadata).
ISO 20524-2 focuses on emerging ITS applications and services, such as Cooperative-ITS and automated driving systems, and it emphasizes road, lane, and relevant information on road and lane. It also focuses on an expansion of the specification to connect with externally existing databases.
ISO 20524-2 is the second part of an international multi-series standard particularly designed to connect a Trans model conformant public transport database.
Note: The conceptual data model specified here has a broader focus than ITS applications and services.
ISO 20524-2 on Geographic Data Files is useful for:
ITS applications have been expanding to Cooperative ITS and automated driving systems through the recent progress of technology. In addition, there is demand for capabilities such as the accommodation of map databases from multiple providers and cooperation with externally connecting databases, such as the Trans model.
ISO 20524-2 presents you with the conceptual and logical data model in addition to the physical encoding formats for geographic databases for information required for ITS applications and services. It adds up to road and road-related information, which are provided as external databases to connect with GDF and to complement each other.
ISO 20524-2 specifies highly defined public transport databases, that are indispensable in multi-modal transport applications and services in particular. It also defines map data for the users, which is very useful in automated driving systems, Cooperative-ITS, and Multi-modal transport.
BS ISO 20524-2:2020 supersedes ISO 14825:2011, which has been withdrawn. BS ISO 20524-2:2020 has been editorially revised and it is newly dedicated to automated driving systems, Cooperative ITS, and multi-modal transport.
