Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Introduction
Autonomous driving technology using artificial intelligence is becoming increasingly important for the safe
operation of vehicles on the road. To be effective, artificial intelligence needs to gather a lot of information
about a vehicle's behaviour and use it to learn. In order to drive safely on the road, self-driving vehicles
need to be aware of the status of other vehicles, road conditions, weather conditions and other external
conditions, in addition to their own vehicle.
As the need for defensive driving increases, it is also important for driver assistance or autonomous driving
systems to understand the driving intentions of other vehicles.
The driving behaviour information set (DBIS) consists of the operations of the subject vehicle and the
associated traffic situation, locally perceived from an egocentric perspective. By sharing this DBIS between
vehicles, it can be used for driving situation prediction algorithms based on artificial intelligence technology
or for real-time optimal driving decisions.
