Intelligent transport systems — Cooperative ITS — Using V2I and I2V communications for applications related to signalized intersections

ISO/TS 19091:2017 defines the message, data structures, and data elements to support exchanges between the roadside equipment and vehicles to address applications to improve safety, mobility and environmental efficiency. In order to verify that the defined messages will satisfy these applications, a systems engineering process has been employed that traces use cases to requirements and requirements to messages and data concepts. This document consists of a single document that contains the base specification and a series of annexes. The base specification lists the derived information requirements (labelled informative) and references to other standards for message definitions where available. Annex A contains descriptions of the use cases addressed by this document. Annex B and Annex C contain traceability matrices that relate use cases to requirements and requirements to the message definitions (i.e. data frames and data elements). The next annexes list the base message requirements and application-oriented specific requirements (requirements traceability matrix) that map to the message and data concepts to be implemented. As such, an implementation consists of the base plus an additional group of extensions within this document. Details on information requirements, for other than SPaT, MAP, SSM, and SRM messages are provided in other International Standards. The focus of this document is to specify the details of the SPaT, MAP, SSM, and SRM supporting the use cases defined in this document. Adoption of these messages varies by region and their adoption may occur over a significant time period. ISO/TS 19091:2017 covers the interface between roadside equipment and vehicles. Applications, their internal algorithms, and the logical distribution of application functionality over any specific system architecture are outside the scope of this document.

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.

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
Cooperative-ITS (C-ITS) is a promising and remarkable advancement of intelligent transport systems
(ITS). Numerous cooperative applications are specified that open up new possibilities to make traffic
safer, more efficient, and smarter. Technologies are developed and improved to realize and support
those new services and applications. To enable those applications, information needs to be reliably
communicated between the stationary infrastructure and mobile vehicles.
This document describes the use cases for several applications that address safety, mobility, and
ecological sustainability. Each use case has information needs that communication between vehicles
and the infrastructure facilitate. It then identifies the information needs for the applications and the
requirements to satisfy them. In turn, it maps the requirements into data frames and data elements to
fulfil the requirements within the specified message set.
ISO 22951 has a relationship to this document. PRESTO addresses its user needs through the
implementation of a specific system architecture similar to that described in NTCIP 1211. This
architecture includes traffic signals, message signs, routing systems, human machine interfaces,
and fixed detection locations. Many of PRESTO’s data value details are “left undefined to allow for
discretional definition by each country.” The PRESTO architecture detects priority requesting vehicles
by installing specific detection equipment at these locations.
This document uses a similar set of user needs to develop the message set between vehicles and the
roadside equipment they interface. This document does not address the system architecture other than
data needed to fulfil the user needs that will be managed elsewhere in the architecture. It details data
values and structures in order to define the interface between these two devices. Routing information
is supported in the architecture through other mechanisms and is not a need supported by the vehicle
to roadside equipment information flows. The user needs also provide for priority by approach,
a preconfigured strategy, and ingress/egress lane requests. This document is based on vehicles
periodically broadcasting their location and trajectory information to other vehicles and the roadside
infrastructure. This document compliments ISO 22951 as it provides for vehicle location and request
information directly from connected vehicles rather than the detection of the vehicles from other fixed
sensing equipment. It does not address the architecture data flows and operations that are detailed
within ISO 2
