BS ISO 15638-20:2020

This standard BS ISO 15638-20:2020 Intelligent transport systems. Framework for cooperative telematics applications for regulated commercial freight vehicles (TARV) is classified in these ICS categories:

• 03.220.20 Road transport
• 35.240.60 IT applications in transport and trade

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:

1. 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);

2. Means to realize the service;

3. 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 can vary between jurisdictions);

4. 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:

1. Application Profile A1: Vehicle weight measurement from “ On-Board Weighing” systems (WIM-O);

2. Application Profile A2: Vehicle weight measurement from in-road ‘weigh-in-motion’ systems where data is transferred to the IVS (WIM-R).

The present version of this document provides specifications for the following communication profiles:

1. Communication Profile 1: Roadside inspection using a short range wireless communication interrogator instigating a physical roadside inspection (master-:-slave):

   1. Profile C1a: via a hand aimed or temporary roadside mounted and aimed interrogator;

   2. Profile C1b: via a vehicle mounted and directed interrogator;

   3. Profile C1c: via a permanent or semi-permanent roadside or overhead gantry.

2. 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):

   1. Profile C2a: via a hand aimed or temporary roadside mounted and aimed interrogator;

   2. Profile C2b: via a vehicle mounted and directed interrogator;

   3. Profile C2c: via a permanent or semi-permanent roadside or overhead gantry.

3. 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 can support additional communication profiles.
