ISO 15638-20:2020(E)

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.
The ISO 15638 TARV series of standards defines and addresses 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 of standards 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 of standards 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.
Consistent with other parts of the ISO 15638 series of standards, this document does not prescribe
nor proscribe particular modes of operation, rather it provides a number of defined communication
and data profiles within which jurisdictions may achieve their objectives for remote weigh-in-motion
monitoring within the objectives and constraints of their regulations. This document recognizes that
those requirements and constraints will differ between jurisdictions.

INTERNATIONAL STANDARD ISO 15638-20:2020(E)
Intelligent transport systems — Framework for
cooperative telematics applications for regulated
commercial freight vehicles (TARV) —
Part 20:
Weigh-in-motion monitoring
1 Scope
This document addresses the provision of ‘weigh-in-motion 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 both on-board weighing (WIM-O) systems and in-road
“weigh-in-motion” (WIM-R) systems, and provides a profile where the vehicle weight measured is
recorded on-board using equipment already installed for “Remote Tachograph Monitoring”.
This document provides specifications for common communications and data exchange aspects of the
application service weigh-in-motion monitoring (WIM-O and WIM-R) 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 has to provide (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 has to deliver, including a number of
profiles for data (noting that requirements and constraints of what can/cannot be transmitted over
the air may vary between jurisdictions);
d) Support for a number of defined communication profiles to enable remote inspection.
The present version of this document provides specifications for the following application profiles:
— Application Profile A1: Vehicle weight measurement from “On-Board Weighing” systems
(WIM-O);
— Application Profile A2: Vehicle weight measurement from in-road ‘weigh-in-motion’ systems
where data is transferred to the IVS (WIM-R).
NOTE 1 Vehicle weight measurement from in-road ‘weigh-in-motion’ systems where data is linked to a specific
vehicle by ANPR or other techniques and sent via landline or cellular communications to a processing centre is also
a viable and alternate option, but as it does not include carrying data on-board the vehicle is not a TARV use case.
The present version of this document provides specifications for the following communication profiles:
— Communication Profile 1: 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;
© ISO 2020 – All rights reserved PROOF/ÉPREUVE 1

---------------------- Page: 7 ----------------------
ISO 15638-20:2020(E)

— Profile C1c: via a permanent or semi-permanent roadside or overhead gantry.
— Communication Profile 2: 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 3: 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).
Subsequent versions of this document may support additional communication profiles.
NOTE 2 The ISO 15638 series of standards has been developed for use in the context of regulated commercial
freight vehicles (hereinafter referred to as ‘regulated vehicles’). There is nothing, however, to prevent a
jurisdiction from extending or adapting the scope to include other types of regulated vehicles, as it deems
appropriate.
