Intelligent transport systems — Framework for collaborative telematics applications for regulated commercial freight vehicles (TARV) — Part 24: Safety information provisioning
The ISO 15638 series (Parts 1 to 23) define the framework for online fleet management of regulated commercial freight vehicles utilizing data communication between in-vehicle systems and an application service provider via an on-board communication unit interfacing with road monitoring infrastructure and roadside sensors. This document defines an unregulated service architecture framework for freight vehicle safety information provision architecture. This statement does not preclude the regulated service where a jurisdiction requires such a function. The objective of this document is to provide a freight vehicle safety information provision service function/application for non-enforcement applications (and sometimes for regulated application services [RAS]). This is for the road transport safety management purposes of regulated commercial freight vehicle movements. This document intends to reinforce vehicle safety for non-enforcement and other purposes by providing safety advisory information provisions to the freight vehicle drivers/operators transporting heavy goods on freight vehicles. This document defines the framework for remote vehicle safety information provision for non-enforcement and the conceptual operation of other management purpose applications. This document is complementary to, and does not replace, any other documents in the ISO 15638 series. This document is beneficial to vehicle safety management purpose entities and it provides additional use cases for TARV service applications. This document is specifically oriented towards the realization of safer road transport of freight vehicles by providing safety advisory information to the vehicle from the service provider. It utilizes the ISO 15638 series basic architecture framework, as defined in ISO 15638-21. The service provider provides users with safety information such as recommended safety information for that vehicle and gives adequate safety advice messages, as necessary. The various V2X communication paths can be used according to the various use cases.

Introduction
Freight vehicles are heavy and therefore require longer reducing speed and manoeuvring distance in
comparison to lighter vehicles. To achieve safer freight road transport of freight vehicles, an information
provision service providing traffic status and incident situation well ahead of the freight vehicle is
indispensable. This information provision can increase vehicle safety during freight road transport.
This document standardizes the conceptual operational framework of safety information provision
provided by service providers. The ISO 15638 series of TARV application standards are based on
a triumvirate of vehicle operators with in-vehicle systems, on-board application service providers
and jurisdictions. The basic TARV ISO 15638-1 standard focuses on the transactions between these
parties via ITS-stations and roadside sensors, and using this system architecture, additional safety
information provision services to freight vehicles can be realized. The new means of safe road transport
management and enforcement can be enabled by using this document where jurisdiction requires such
regulated monitoring.
It therefore seems appropriate to include this additional document (Part 24) in the ISO 15638 series to
provide the means for adding safe road transport of freight vehicles.
It is necessary for telematic applications to be able to be integrated into the embedded computing
systems available on the market. The need for interoperability of different solutions is also important
as several actors with different solutions can be involved in information needs. Securing the data
exchanged is also a particularly important point.
NOTE Related to EC regulations, ISO 15638-9 already covers provisions consistent with EC 165/2014.
This document is complementary to and not competitive with ISO 15638-9, and is therefore consistent with EC

5 Conformance
Requirements to demonstrate conformance to any of the general provisions or specific application
services described in this document shall be within the requirements defined by the service provider.
Conformance requirements to meet the provisions of this document are therefore deemed to be under
the control of, and to the specification of, the service provider where the application service(s) is/are
instantiated.
6 General overview and framework
This document utilizes the framework and architecture for freight vehicle stability monitoring defined
in ISO 15638-21. The general conceptual operation description of the roles of the actors in "extended"
TARV architecture is defined in ISO 15638-21.
To gain an in-depth understanding of the extended TARV framework, architecture, and detailed
specification of the roles of the actors involved, the user shall consult ISO 15638-1, ISO 15638-7 and
ISO 15638-21.
As a summary, Figure 1 shows the "extended" role model conceptual architecture showing the key
actors and their relationships as defined in ISO 15638-21.

ISO 15638-24:2021(E)
Figure 1 — Extended role model conceptual architecture
The ISO 15638 series provides a suite of deliverables addresses and defines the framework for a range
of cooperative telematics applications for regulated vehicles (such as electronic tachograph monitoring,
driver work records, emergency messaging/eCall, mass monitoring, 'Mass' information for jurisdictional
control and enforcement, speed monitoring, access control, access methods, location monitoring, weigh
in motion, freight vehicle stability monitoring, tyre monitoring, etc.). The overall scope includes the
concept of operation, legal and regulatory issues, and the generic C-ITS service platform. The framework
is based on a (multiple) service provider-oriented approach, including provisions for the certification
and auditing of service providers.
This document is intended for an unregulated service provision application for safe road transport by
freight vehicles, achieved through the safety information provision to the vehicle, such as safe driving
information provision (including information such as recommended safe speed and recommended
driving lane change advice information). Figure 2 shows the architecture from the viewpoint of the
provision of an unregulated (commercial) application service, using the common "extended" TARV
platform defined in ISO 15638-21.

Figure 2 — Role model conceptual architecture unregulated service provisioning
Freight vehicles are heavy and therefore require longer reducing speed and manoeuvring distance
in comparison to lighter vehicles. To achieve safer freight road transport of freight vehicles, an
information provision service providing traffic status and incident situation well ahead of the freight
vehicle is indispensable. The purpose of this document is to realize safe freight vehicle road transport,
in particularly increasing the vehicle safety by maintaining the safe speed and lane change of a freight
vehicle transporting freight and container. The proper recommended speed and lane information given
to the vehicle driver/operator is generated at the service provider; they monitor vehicle speed/lane and
give safety advisory messages to the driver when necessary. This document enables safe freight vehicle
road transport stability realization and efficient freight fleet transport operation of the user vehicles by
avoiding accidents or serious incidents on the roadways.
The freight vehicle information can be obtained from various sources, such as roadside embedded
sensors, freight vehicle on-board equipped sensors. The sensor information is sent to the service
provider to realize real time remote monitoring of freight vehicles and the service provider provides the
safety driving advice for that part of the road for that vehicle. By providing the freight vehicle location
(GNSS) data to the service provider, the service provider can provide adequate safe road transport
driving information for that part of the road and for that vehicle (model).
The service provider provides this application service to/for a user who is an individual or party that
enrols in and operates within an unregulated application service or commercial application service

ISO 15638-24:2021(E)
to meet specific aspects of the requirements of a service provider for the operation of the regulated
vehicle.
Examples of users are a transport operator, driver, freight owner, etc. Most commonly the user is the
transport operator.
For basic TARV information, refer to ISO 15638-1.
This document defines the basic conceptual operational requirement for this application service, the
freight vehicle safety information provision.
It is important to note that where a commercial (unregulated) service can be instantiated using only
the generic vehicle data specified in ISO 15638-5, no further standardization is required. Where a
TARV commercial application is simply instantiated as a commercial application conforming to the
requirements of this document, no further standardization is required so long as conformance to the
requirements of this document can be demonstrated, and service offerings may vary from service
provider to service provider. The service provider provides the application service to/for a ‘user’ who
is an individual or party that enrols and contracts to receive the commercial/civic application service.
7 Basic conceptual operational requirement
7.1 General
The basic conceptual framework is described as shown in Figure 3.
The telematic application generates adequate safety information so that an accident is avoided (tail end
collision, crush, rollover, jack-knifing). This safety information depends on the road characteristic and
the dynamic behaviour of the vehicle configuration.
It is important that dealing with the vehicle model/configuration (power unit and connected trailer(s))
is based on the interaction between the road and the vehicle, because this depends on the vehicle
model/configuration.
Moreover, the quality of the estimated speed is based on the accuracy of the model.

NOTE 2 Road sensor information: traffic volume, speed, road works, accidents, ice, snow, stationary vehicles,
obstacles, etc.
Figure 3 — Basic conceptual framework for vehicle safety information provisioning service
7.2 Basic requirement
The basic requirements are as follows:
a) The vehicle shall be equipped with vehicle safety monitoring sensors and such data shall be sent
to the service provider through on-board unit ITS communication media connected with the
service provider. If the vehicle does not have such sensors, only roadside sensor data is used, and
continuous data acquisition is not possible.
b) An on-board safety sensor shall monitor vehicle safety continuously and shall detect driving status.
A roadside sensor shall detect similar status when a freight vehicle passes through it.
c) Vehicle location data shall be sent to the service provider so that service provider is able to track
and trace the vehicle on the LDM and the vehicle location can be utilized to provide adequate safety
advice for that vehicle.

infrastructure and roadside sensors. This document defines an unregulated service architecture
framework for freight vehicle safety information provision architecture. This statement does not
preclude the regulated service where a jurisdiction requires such a function.
The objective of this document is to provide a freight vehicle safety information provision service
function/application for non-enforcement applications (and sometimes for regulated application
services [RAS]). This is for the road transport safety management purposes of regulated commercial
freight vehicle movements.
This document intends to reinforce vehicle safety for non-enforcement and other purposes by providing
safety advisory information provisions to the freight vehicle drivers/operators transporting heavy
goods on freight vehicles.
This document defines the framework for remote vehicle safety information provision for non-
enforcement and the conceptual operation of other management purpose applications.
This document is complementary to, and does not replace, any other documents in the ISO 15638 series.
This document is beneficial to vehicle safety management purpose entities and it provides additional
use cases for TARV service applications.
This document is specifically oriented towards the realization of safer road transport of freight
vehicles by providing safety advisory information to the vehicle from the service provider. It utilizes
the ISO 15638 series basic architecture framework, as defined in ISO 15638-21. The service provider
provides users with safety information such as recommended safety information for that vehicle and
gives adequate safety advice messages, as necessary. The various V2X communication paths can be
used according to the various use cases.

Requirements to demonstrate conformance to any of the general provisions or specific application
services described in this document shall be within the requirements defined by the service provider.
Conformance requirements to meet the provisions of this document are therefore deemed to be under
the control of, and to the specification of, the service provider where the application service(s) is/are
instantiated.
6 General overview and framework
This document utilizes the framework and architecture for freight vehicle stability monitoring defined
in ISO 15638-21. The general conceptual operation description of the roles of the actors in "extended"
TARV architecture is defined in ISO 15638-21.
To gain an in-depth understanding of the extended TARV framework, architecture, and detailed
specification of the roles of the actors involved, the user shall consult ISO 15638-1, ISO 15638-7 and
ISO 15638-21.
As a summary, Figure 1 shows the "extended" role model conceptual architecture showing the key
actors and their relationships as defined in ISO 15638-21.

Figure 1 — Extended role model conceptual architecture
The ISO 15638 series provides a suite of deliverables addresses and defines the framework for a range
of cooperative telematics applications for regulated vehicles (such as electronic tachograph monitoring,
driver work records, emergency messaging/eCall, mass monitoring, 'Mass' information for jurisdictional
control and enforcement, speed monitoring, access control, access methods, location monitoring, weigh
in motion, freight vehicle stability monitoring, tyre monitoring, etc.). The overall scope includes the
concept of operation, legal and regulatory issues, and the generic C-ITS service platform. The framework
is based on a (multiple) service provider-oriented approach, including provisions for the certification
and auditing of service providers.
This document is intended for an unregulated service provision application for safe road transport by
freight vehicles, achieved through the safety information provision to the vehicle, such as safe driving
information provision (including information such as recommended safe speed and recommended
driving lane change advice information). Figure 2 shows the architecture from the viewpoint of the
provision of an unregulated (commercial) application service, using the common "extended" TARV
platform defined in ISO 15638-21.

Figure 2 — Role model conceptual architecture unregulated service provisioning
Freight vehicles are heavy and therefore require longer reducing speed and manoeuvring distance
in comparison to lighter vehicles. To achieve safer freight road transport of freight vehicles, an
information provision service providing traffic status and incident situation well ahead of the freight
vehicle is indispensable. The purpose of this document is to realize safe freight vehicle road transport,
in particularly increasing the vehicle safety by maintaining the safe speed and lane change of a freight
vehicle transporting freight and container. The proper recommended speed and lane information given
to the vehicle driver/operator is generated at the service provider; they monitor vehicle speed/lane and
give safety advisory messages to the driver when necessary. This document enables safe freight vehicle
road transport stability realization and efficient freight fleet transport operation of the user vehicles by
avoiding accidents or serious incidents on the roadways.
The freight vehicle information can be obtained from various sources, such as roadside embedded
sensors, freight vehicle on-board equipped sensors. The sensor information is sent to the service
provider to realize real time remote monitoring of freight vehicles and the service provider provides the
safety driving advice for that part of the road for that vehicle. By providing the freight vehicle location
(GNSS) data to the service provider, the service provider can provide adequate safe road transport
driving information for that part of the road and for that vehicle (model).
The service provider provides this application service to/for a user who is an individual or party that
enrols in and operates within an unregulated application service or commercial application service

to meet specific aspects of the requirements of a service provider for the operation of the regulated
vehicle.
Examples of users are a transport operator, driver, freight owner, etc. Most commonly the user is the
transport operator.
For basic TARV information, refer to ISO 15638-1.
This document defines the basic conceptual operational requirement for this application service, the
freight vehicle safety information provision.
It is important to note that where a commercial (unregulated) service can be instantiated using only
the generic vehicle data specified in ISO 15638-5, no further standardization is required. Where a
TARV commercial application is simply instantiated as a commercial application conforming to the
requirements of this document, no further standardization is required so long as conformance to the
requirements of this document can be demonstrated, and service offerings may vary from service
provider to service provider. The service provider provides the application service to/for a ‘user’ who
is an individual or party that enrols and contracts to receive the commercial/civic application service.
7 Basic conceptual operational requirement
7.1 General
The basic conceptual framework is described as shown in Figure 3.
The telematic application generates adequate safety information so that an accident is avoided (tail end
collision, crush, rollover, jack-knifing). This safety information depends on the road characteristic and
the dynamic behaviour of the vehicle configuration.
It is important that dealing with the vehicle model/configuration (power unit and connected trailer(s))
is based on the interaction between the road and the vehicle, because this depends on the vehicle
model/configuration.
Moreover, the quality of the estimated speed is based on the accuracy of the model.

7.2 Basic requirement
The basic requirements are as follows:
a) The vehicle shall be equipped with vehicle safety monitoring sensors and such data shall be sent
to the service provider through on-board unit ITS communication media connected with the
service provider. If the vehicle does not have such sensors, only roadside sensor data is used, and
continuous data acquisition is not possible.
b) An on-board safety sensor shall monitor vehicle safety continuously and shall detect driving status.
A roadside sensor shall detect similar status when a freight vehicle passes through it.
c) Vehicle location data shall be sent to the service provider so that service provider is able to track
and trace the vehicle on the L
