1 Scope
This part of ISO 15638 addresses the provision of ‘vehicle speed monitoring’ and specifies the form and content of such data required to support such systems, and access methods (4.2) to that data.
The scope of this part of ISO 15638 is to provide specifications (4.42) for common communications and data exchange aspects of the application service (4.4)vehicle speed monitoring that a regulator (4.28) can elect to require or support as an option, including
-
a) high level definition of the service that a service provider (4.40) has to provide (The service definition describes common service elements but does not define the detail of how such an application service (4.4) is instantiated, nor the acceptable value ranges of the data concepts defined),
-
b) means to realize the service, and
-
c) application data, naming content, and quality that an IVS (4.25) has to deliver.
The definition of what comprises a ‘regulated’ service is regarded as an issue for National decision, and can vary from jurisdiction (4.28) to jurisdiction. This International Standard 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 standardised sets of requirements descriptions for identified services to enable consistent and cost efficient implementations where instantiated.
This International Standard has been developed for use in the context of regulated commercial freight vehicles [hereinafter referred to as ‘regulated vehicles’ (4.38)]. However, there is nothing to prevent a jurisdiction extending or adapting the scope to include other types of regulated vehicles, as it deems appropriate.
