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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of document:
— an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical
experts in an ISO working group and is accepted for publication if it is approved by more than 50 %
of the members of the parent committee casting a vote;
— an ISO Technical Specification (ISO/TS) represents an agreement between the members of a
technical committee and is accepted for publication if it is approved by 2/3 of the members of the
committee casting a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for
a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or
ISO/TS is confirmed, it is reviewed again after a further three years, at which time it must either be
transformed into an International Standard or be withdrawn.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

Introduction
Probe vehicle systems are being investigated and deployed throughout the world. It is expected that
the number of practical systems will grow steadily over the next few years. In TC 204/SWG 16.3,
probe vehicle systems and probe data have been examined, and it is concluded that in many cases
communications airtime will be a scarce and expensive commodity, and therefore efficient probe data
reporting systems which rely on techniques to use airtime efficiently and economically are essential.
One way to accomplish this is to shift data aggregation tasks in to the probe vehicle itself. Vehicles that
feature this advanced form of on board probe data processing will report information based on the
occurrence of actual events as opposed to delivering a constant stream of raw vehicle probe data. Event-
based probe data reporting will allow economic use of communication capacity.
As probe vehicle systems have to collect and manage probe data from a variety of vehicles from different
vehicle manufacturers, the standardization of these event-based messages is essential. To do this, a
common framework for event-based probe vehicle message reporting is also required.
The purpose of this project is to develop (1) a reference architecture for event-based probe data reporting
within an architecture which encompasses both this function and standard probe data reporting defined
in ISO 22837; (2) the basic data framework for defining event-based probe data messages; and (3) the
concrete definition of these messages.
The benefits of this standardization include:
— It helps system developers and operators to specify efficient probe data collection and processing
systems. It also promotes communication and mutual understanding among the developers and the
operators of probe systems.
— It helps system developers who are developing probe vehicle systems to define a key tool for
communications-efficient probe data systems, i.e. event-based probe data reporting.
— Probe data may be collected from various vehicles of different vehicle manufacturers. It provides a
common framework for handling event-based probe data.

Intelligent transport systems — Event-based probe vehicle
data
1 Scope
This Technical Specification specifies:
— reference architecture for event-based probe vehicles which encompasses event-based probe data
and standard probe data elements (ISO 22837:2009);
— basic data framework of event-based probe data reporting, based on ISO 22837:2009;
— the definition of an initial set of event-based probe data elements. These elements will be commonly
used in typical event-based probe data enabled application domains, such as traffic, weather, and
safety. Standardizing these event-based probe data elements facilitates the development of probe
vehicle systems and the distribution of probe data. This is not intended to be an exhaustive listing
of event-based probe data probe data elements.
This Technical Report provides a common framework for defining event-based probe data messages to
facilitate the specification and design of probe vehicle systems.
It provides concrete definitions of event-based probe data elements.
It serves as a supplement to ISO 22837:2009, and specifies additional normative data (probe data
elements) that are delivered by an event-based probe data system.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 22837:2009, Vehicle probe data for wide area communications
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
probe vehicle system
system consisting of vehicles which collect and transmit probe data and land-based centres which
collate and process data from many vehicles to build an accurate understanding of the overall roadway
and driving environment
[ISO 22837:2009, 4.1]
3.2
vehicle sensor
device within a vehicle that senses conditions inside and/or outside the vehicle or that detects actions
that the driver takes
[ISO 22837:2009, 4.2]
3.3
probe data
vehicle sensor information formatted as probe data elements and/or probe messages that is processed,
formatted, and transmitted to a land-based centre for processing to create a good understanding of the
driving environment
[ISO 22837:2009, 4.3]
3.4
event-based probe message
stuctured collation of probe data elements that represents occurrence of a defined event for transmission
to a land-based centre
Note 1 to entry: An event-based probe data message is sent only when a specific incident or event occurs. It is not
transmitted in a periodic manner. The transmission of an event-based probe message itself indicates that an event
has occurred. An event-based probe message is defined as a probe message that is not triggered by a periodically
occurring condition (i.e. time or distance). A typical trigger is the detection of a different situation by the vehicle
on board system (i.e. low visibility or traffic jam entry). An event may be defined as a simple incident, such as a
change in status of a standard probe data element (i.e. fog light switching state), or can refer to a complex incident
detected by a detection algorithm (i.e. traffic jam entry).
3.5
probe data element
data item included in a probe message
[ISO 22837:2009, 4.4]
3.6
event-based probe data element
item of data included in an event-based probe message, typically describing the event that has triggered
the transmission of the message
3.7
core data element
probe data element which appears in all probe messages
[ISO 22837:2009, 4.5]
3.8
probe message
structured collation of data elements suitable to be delivered to the onboard communication device for
transmission to a land-based centre
Note 1 to entry: It is emphasized that a probe message should not contain any information that identifies the
particular vehicle from which it originated or any of the vehicle’s occupants, directly or indirectly. In delivering a
probe message to be transmitted by the onboard communication device, the onboard data collection system will
request that the message be packaged and transmitted without any vehicle or occupant identifying information.
[ISO 22837:2009, 4.6]
3.9
processed probe data
data from probe data messages which has been collated and analysed in combination with other data
[ISO 22837:2009, 4.7]

4.1 Reference architecture for probe vehicle systems

components and their relationships from a conceptual point of view. A component is depicted as a
