Introduction
Many ITS technologies have been embraced by commercial transport operators and freight owners
in the areas of fleet management, safety and security. On-board applications have also been developed
for governmental use. Such regulatory services in use or being considered vary from jurisdiction to
jurisdiction, but include electronic on-board recorders, digital tachograph, on-board mass monitoring,
‘mass’ data for regulatory control and management weigh-in-motion, vehicle access methods, hazardous
,
goods tracking and eCall. Additional applications with a regulatory impact being developed include fatigue
management, speed monitoring and vehicle penalties imposed based on location, distance and time.
In such an emerging environment of regulatory and commercial applications, it is timely to consider an
overall architecture (business and functional) that could support these functions from a single platform
within a commercial freight vehicle that operates within such regulations. International Standards will
allow for a speedy development and specification of new applications that build upon the functionality
of a generic specification platform. A series of standards deliverables is required to describe and define
the framework and requirements so that the on-board equipment and back office systems can be
commercially designed in an open market to meet common requirements of jurisdictions.
The ISO 15638 TARV series addresses and defines the framework for a range of cooperative telematics
applications for regulated vehicles (e.g. access methods, driver fatigue management, speed monitoring,
on-board mass monitoring, Remote Tachograph Monitoring, ADR management). The overall scope
includes the concept of operation, legal and regulatory issues, and the generic cooperative provision of
services to regulated vehicles, using an on-board ITS platform. The framework is based on a (multiple)
service provider-oriented approach with provisions for the approval and auditing of service providers.
The ISO 15638 series provides both the means to achieve current requirements for telematics
applications for regulated vehicles and the basis for future development of cooperative telematics
applications for regulated vehicles.
The ISO 15638 series is timely, as many governments (Europe, North America, Asia and Australia/New
Zealand) are considering the use of telematics for a range of regulatory purposes.
This document provides specifications for weigh-in-motion and on-board weighing monitoring and
supports several defined communication profiles in which this function may be performed.
NOTE 1 The definition of what comprises a ‘regulated’ vehicle is regarded as an issue for national decision and
can vary from jurisdiction to jurisdiction. This series does not impose any requirements on nations in respect of
how they define a regulated vehicle.
NOTE 2 The definition of what comprises a ‘regulated’ service is regarded as an issue for national decision and
can vary from jurisdiction to jurisdiction. This series does not impose any requirements on nations in respect
of which services for regulated vehicles jurisdictions they will require, or support as an option, but will provide
standardized sets of requirements descriptions for identified services to enable consistent and cost-efficient
implementations where implemented.

INTERNATIONAL STANDARD ISO 15638-9:2020(E)
Intelligent transport systems — Framework for
cooperative telematics applications for regulated
commercial freight vehicles (TARV) —
Part 9:
Remote digital tachograph monitoring
1 Scope
This document addresses the provision of ‘Remote Digital Tachograph Monitoring’ and specifies
the form and content of the transmission of such data required to support such systems, and access
methods to that data.
This document provides specifications for common communications and data exchange aspects of
the application service remote digital tachograph monitoring that a jurisdiction regulator can elect to
require or support as an option, including:
a) High level definition of the service that a service provider provides. The service definition describes
common service elements but does not define the detail of how such an application service is
instantiated, nor the acceptable value ranges of the data concepts defined.
b) Means to realize the service.
c) Application data naming, content and quality that an IVS delivers, including a number of profiles for
data (noting that requirements and constraints of what can/cannot be transmitted over the air can
vary between jurisdictions).
d) Support for a number of defined communication profiles to enable remote inspection.
This document is not applicable for analogue tachograph equipment/systems.
This document provides specifications for the following communication profiles:
— Communication Profile C1: Roadside inspection using a short-range wireless communication
interrogator instigating a physical roadside inspection (master<>slave)
Profile C1a: via a hand aimed or temporary roadside mounted and aimed interrogator
Profile C1b: via a vehicle mounted and directed interrogator
Profile C1c: via a permanent or semi-permanent roadside or overhead gantry
— Communication Profile C2: Roadside inspection using a short-range wireless communication
interrogator instigating a download of data to an application service provider via an ITS-
station communication (master<>slave + peer<>peer)
Profile C2a: via a hand aimed or temporary roadside mounted and aimed interrogator
Profile C2b: via a vehicle mounted and directed interrogator
Profile C2c: via a permanent or semi-permanent roadside or overhead gantry
— Communication Profile C3: Remote inspection addressed via an ITS-station instigating a
download of data to an application service provider via a wireless communications interface
(as defined in ISO 15638-2).
It is possible that subsequent versions of this document will support additional communication profiles.
NOTE 1 The definition of what comprises a ‘regulated’ service is regarded as an issue for national decision
and can vary from jurisdiction to jurisdiction. This document does not impose any requirements on nations in
respect of which services for regulated vehicles jurisdictions will require, or support as an option, but provides
standardized sets of requirements descriptions for identified services to enable consistent and cost-efficient
implementations where instantiated.
NOTE 2 The ISO 15638 series has been developed for use in the context of regulated commercial freight
vehicles (hereinafter referred to as ‘regulated vehicles’). However, there is nothing to prevent a jurisdiction from
extending or adapting the scope to include other types of regulated vehicles, as it deems appropriate.

— Communication Profile C3: Remote inspection addressed via an ITS-station instigating a
download of data to an application service provider via a wireless communications interface
(peer<>peer) (as defined in ISO 15638-2)
See 6.4 for overview.
NOTE Within the Member States of the European Union, remote tachograph monitoring is controlled by
Regulation 2016/799/EC and its Appendix 14, which was published on 2016-05-26 and entered into force from
2016-06-15. This constrains remote tachograph monitoring in the European Union to the transaction defined in
Annex B using 5,8 GHz DSRC. Annex B is consistent with this Regulation. For European regulatory requirements
regarding the short-range communications interface see 2016/799/EC Appendix 14.
6.2 Overview of Communication Profile C1 — Remote roadside inspection using
a short-range wireless communication interrogator instigating a physical roadside
inspection
6.2.1 General overview of Communication Profile C1
This profile covers the use case where an agent of the jurisdiction:
a) Uses a short-range communication interrogator to remotely identify a vehicle which is potentially
in violation of the tachograph regulations of the jurisdiction.
b) Once identified, the agent of the jurisdiction controlling the interrogation decides whether the
vehicle should be stopped, and if so, instructs colleagues downstream to stop the vehicle and effect
a physical download of data from the vehicle, or may pass the data directly to them to enable them
to make such decisions.
This scenario is appropriate (but not limited to) situations where local data requirements require the
physical ‘arrest’ of a vehicle potentially in violation of regulations and/or where the regulations require
a physical download of data made by an agent of the jurisdiction, directly from the ‘arrested’ vehicle in
order to support a prosecution, and/or situations where data concerning the driver is prohibited from
being sent via wireless communications.
There are three subset profiles of this remote inspection:
6.2.1.1 Profile C1a — Via a hand aimed or temporary roadside mounted and aimed
interrogator
In this use case the agent of the jurisdiction is situated at the roadside, and aims a hand held,
