ISO has released three technical standards concentrating on intelligent transport systems (ITS), all of which are centered on traffic and travel information through Transport Protocol Experts Group Generation 2 (TPEG2). These are:
Intelligent transport (or transportation) systems (ITS) encompass a wide range of technologies, and the general label has been used to identify any effort through engineering or information technology that improves transportation safety and mobility. A successful ITS enhances productivity through the integration of advanced communications technologies into vehicles and the transportation infrastructure.
Intelligent transport systems are complex, and can be difficult to comprehend. The ITS Professional Capacity Building (ITS PCB) Program offers a variety of free resources to educate individuals on ITS, including deliver classroom, web-based, and blended courses, and webinars on different topics.

TPEG2 is the official standard protocol for broadcasting traffic and travel-related information in the multimedia environment. All TPEG technology and applications were designed to be coded, decoded, filtered, and understood by humans and agent systems. TPEG2 is built specifically around UML modeling, and has a three container conceptual structure: Message Management, Application, and Location Referencing.
TPEG2 is partitioned into a number of parts in the ISO/TS 21219 series. Each of these parts is given a descriptive title relative to its application, which is reduced to a three-letter acronym. For example, the TPEG Service and Network Information application is abbreviated as TPEG2-SNI.
ISO/TS 21219-1:2016 (TPEG2-INV) serves as the index to the TPEG2 toolkit, helping establish names, categories, and rules for the entire system. This also applies Application Identification (AID) as new applications are added to the TPEG application family.
ISO/TS 21219-9:2016 is meant to standardize the method of delivering service and network information (TPEG2-SNI) during TPEG service use. TPEG2-SNI is meant to use language understandable to all service providers so that they can view the availability of services to simplify the delivery of information.
ISO/TS 21219-10:2016 is focused on the Conditional Access Information (TPEG2-CAI), which provides security for the information of the entire system.
However, these three standards only address some of the applications that are incorporated into the TPEG 2 ITS system. Other standards in the ISO/TS 21219 series encompass procedures for converting past models into current ones, conveying data, managing information, and using predictive data to improve traffic patterns.
The other intelligent transport systems in this series include:
ISO 21219-2:2019 – Intelligent transport systems – Traffic and travel information (TTI) via transport protocol experts group, generation 2 (TPEG2) – Part 2: UML modeling rules (TPEG 2-UMR)
ISO 21219-3:2019 – Intelligent transport systems – Traffic and travel information (TTI) via transport protocol experts group, generation 2 (TPEG2) – Part 3: UML to binary conversion rules (TPEG2-UBCR)
ISO 21219-4:2019 – Intelligent transport systems – Traffic and travel information (TTI) via transport protocol experts group, generation 2 (TPEG2) – Part 4: UML to XML conversion rules
ISO 21219-5:2019 – Intelligent transport systems – Traffic and travel information (TTI) via transport protocol experts group, generation 2 (TPEG2) – Part 5: Service framework (TPEG2-SFW)
ISO/TS 21219-6:2019 – Intelligent transport systems – Traffic and travel information via transport protocol experts group, generation 2(TPEG2) – Part 6: Message management container (TPEG2-MMC)
ISO/TS 21219-18:2019 – Intelligent transport systems – Traffic and travel information (TTI) via transport protocol experts group, generation 2 (TPEG2) – Part 18: Traffic flow and prediction application (TPEG2-TFP)
An informative read on intelligent transportation system standards. With the global market for these systems valued at around 26 billion USD in 2018, and still growing at a double-digit rate according to a report by Grand View Research, the time is crucial for implementation of these standards in the strictest manner possible.
