Specialist Task Force 565:

Road Users (VRU) service

What we do
The purpose of the STF is to produce a consistent set of specifications
related to Vulnerable Road Users (VRU) in alignment with non-European
developments on the same topic (for instance in the US) in response to
M/453 (Cooperative Intelligent Transport Systems or C-ITS) and M/546
(Urban ITS) and in accordance with ITS Actions 3 and 21 of the 2018
Rolling Plan for ICT Standardisation. The STF will provide a) the
description of the VRU system and main use cases, b) the specification
of VRU-related requirements, and functional architecture of the VRU
system, and c) the specification of the VRU awareness basic service.

Why we do it
Technological developments and research activities in ITS have primarily
focused on motorised transport to improve safety and environmental
impacts by advancing equipment of vehicles and infrastructure. The
uptake of ITS applications has assisted in the decrease of road traffic
fatalities, particularly amongst passenger car occupants. However,
Vulnerable Road Users (VRUs) have not enjoyed the same decrease in
fatalities. Together, they account for 68% of the fatalities in urban
areas (CARE, 2009). Motorcyclists account for 16% of fatalities, which
is much higher than their contribution to traffic. In the context of
Cooperative-ITS (C-ITS) systems, VRUs have to be taken into account and
therefore interoperability between vehicle-based and portable safety
devices is of paramount importance to improve the overall safety and
decrease the fatalities in both urban and non-urban areas. There is
therefore the need to develop VRU related specifications in order to
allow the deployment of VRU safety applications.
How we do it
The work of the STF has been split into 4 main tasks. It is performed
under the guidance of ETSI TC ITS, and more precisely its Working Group
WG1 (Application Requirements and Services). Other WGs may provide
support to the activities where additional feedback is needed, e.g.
resource estimation from WG4 and ETSI TC ERM TG37, or security from WG5.
Task 1 – Project Management and coordination with other
organizations
Objectives: Coordination, communication, reporting and leading of
the STF team activities, in collaboration with the ETSI secretariat and
the steering committee.
Another objective of this task is to ensure that the STF fluently
interacts with relevant actors in the C-ITS/VRU field in order to ensure
that the work is well coordinated and synchronised.
Task 2 – Definition of the VRU use cases
Objectives: The objective of Task 2 is to provide a varied and
relevant set of use cases related to Vulnerable Road Users such as
pedestrians, bicyclists and road workers. Each use case will be
described in detail and an associated flow chart will show the
interaction between the involved actors.
The work in this task will consist also in the collection and taking
into consideration of the results from relevant projects and
organizations on VRU use cases and system architecture during the STF
first weeks of activity. An ad'hoc meeting is being organised by the STF
as a post-ITS workshop meeting on March 6, 2019
(https://www.etsi.org/events/1471-etsi-its-workshop-2019) to help
collect these inputs from previous activities and share valuable
opinions from interested stakeholders.
The methodology for the development of the Technical Report will be the
following:
• Analysis of the
existing material and specifications related to Vulnerable Road Users
• Categorization of VRUs
• Definition of VRU system components
• Categorization of use cases
• Description of use cases
Task 3 – Project Management and coordination with other
organizations
Objectives: The objective of Task T3 is to derive from the use
cases described in Task 2 the functional architecture of the VRU system,
as well as the requirements for later standardisation activities.
The definition of the VRU-related requirements will be based on the use
cases defined in Task 2 and will take into account all the work already
done in other standards and specifications such as SAE J2945 (Vulnerable
Road User Safety Message Minimum Performance Requirements). In addition,
the outcome of relevant past or ongoing H2020 projects will be
scrutinized.
The methodology for the development of the Technical Specification will
be the following:
• Analysis of the
existing material and specifications related to Vulnerable Road Users,
including the C-ITS platform for VRU services
• Analysis of the VRU use cases identified in Task 2
• Categorization and definition of VRUs
requirements: system requirements, operational requirements,
communication requirements, security requirements, etc.
• Definition of VRU functional architecture
• Identification of the impacts on existing ITS
standards and protocols
Task 4 – Project Management and coordination with other
organizations
Objectives: The objective of Task 4 is to specify how VRU safety
can be ensured by a VRU awareness service. This Task will specify the
communication protocols, message format, semantics and syntax as well as
key interfaces and service protocol operation for the VRU awareness
service.
The methodology for the development of the Technical Specification will
be the following:
• Analysis of the
outcome of Task 2 and Task 3
• Definition of interfaces in the context of ITS
architecture
• Specification of the message
• Specification of the protocol operation
