PD ISO/TR 21718:2019

What is ISO/TR 21718 - Cooperative ITS and automated driving systems about?  

Cooperative intelligent transport systems (ITS) and automated driving systems as energy-saving technology have attracted much attention. These systems are expected to reduce traffic congestion and achieve smoother transportation. Spatiotemporal data for ITS which includes static and dynamic temporal-spatial data will be required for cooperative ITS and automated driving systems. In order to create, provide and maintain these data, much more resources will be required. 

ISO/TR 21718 is a compilation of terms to be contained in a spatio-temporal data dictionary for cooperative-ITS and automated driving systems.  

This data dictionary includes static data (e.g. map, road signs and buildings) and dynamic data (e.g. traffic condition, accident reports). 

Who is ISO/TR 21718 - Cooperative ITS and automated driving systems for? 

ISO/TR 21718  on cooperative ITS and automated driving systems is useful for: 

• Transport authorities 
• Traffic management systems 
• Research and development team 
• Automated driving ITS 

Why should you use ISO/TR 21718 - Cooperative ITS and automated driving systems?  

In the existing ITS applications, geographical information is optimally designed for individual systems. 

Thus, many resources are required in order to create, provide and maintain this information. Spatiotemporal data can be used for different types of application systems. A common understanding 

and sharing of spatiotemporal data is formulated by this data dictionary. Spatiotemporal data for ITS includes location information or has relationships with location. 

ISO/TR 21718 provides you with contents and descriptive names of data dictionary which consist of data concept name, data concept type, data status category, definition and description, and data structure. 

ISO/TR 21718 introduces the data concept name of SAE J 2735: Dedicated Short-Range Communications (DSRC) Message Set Dictionary which contain many concepts for the cooperative ITS and automated driving systems. 

Compliance with ISO/TR 21718, standardization of spatiotemporal data dictionary contributes to research and development and dissemination of cooperative ITS and automated systems. 

What’s changed since the last update? 

PD ISO/TR 21718:2019 supersedes PD ISO/TR 21718:2017, which has been technically revised. PD ISO/TR 21718:2019 includes some technical changes with respect to PD ISO/TR 21718:2017. These include: 

• Task force team have collaborated with SAE, and combined the SAE deliverable and the first edition 
• The list of the data concept names described in SAE J 2735: 2016 have been included as Annex B
