About ISO/TC204 Intelligent Transport Systems

Overview

Since our establishment in 1992, TC204 has developed and maintained a suite of standards and other artefacts for the Intelligent Transport Systems (ITS) environment that generally exists OUTSIDE a vehicle, and interfaces to the ITS environment INSIDE a vehicle.

Our 340+ active documents collectively describe: * a common ITS framework including: * Reference ITS Architecture * ITS Services * Terminology and Definitions * Data Concepts and a Central ITS Data Concepts Register (CIDCR) 🚧Correct link to be added * A Registry of ITS Information (RITSI) * many specialised deliverables that describe and define various components that help deliver ITS Services and solutions.

TC204 and our work exists within a much broader operating context requiring collaboration with other developers of related standards, both within ISO (such as TC22 Road Vehicles and TC344 Innovative Logisitics) and beyond (such as CEN/TC278 ITS Standards and ISO/IEC/JTC 1/WG 11 Smart cities). Our current liaisons are illustrated below, with links available here.

TC204 Committee Structure

TC204 delivers its official work programme through a broad range of groups consisting of: * WG - Working Groups within TC204 * AG - Advisory Groups (typically special projects / initiatives) * JWG - Joint Working Groups to formally collaborate with experts outside of TC204 (such as other ISO/TCs or other SDOs).

Our structure is shown below together with our Participating and Observing members. All of TC204’s groups and convenors may be approached via the TC204 Secretariat.
