This International Standard establishes requirements for short-range communication for the purposes
of augmenting the localization in autonomous electronic fee collection (EFC) systems. Localization
augmentation serves to inform on-board equipment (OBE) about geographical location and the
identification of a charge object. This International Standard specifies the provision of location and
heading information and security means to protect from the manipulation of the OBE with false
roadside equipment (RSE).
The localization augmentation communication takes place between an OBE in a vehicle and fixed roadside
equipment. This International Standard is applicable to OBE in an autonomous mode of operation.
This International Standard defines attributes and functions for the purpose of localization
augmentation, by making use of the dedicated short-range communications (DSRC) communication
services provided by DSRC Layer 7, and makes these LAC attributes and functions available to the LAC
applications at the RSE and the OBE. Attributes and functions are defined on the level of Application
Data Units.
This International Standard is applicable to:
— the application interface definition between OBE and RSE;
— the interface to the DSRC application layer, as specified in ISO 15628 and EN 12834;
— the use of the DSRC stack.
The localization augmentation communication is suitable for a range of short-range communication
media. This International Standard gives specific definitions regarding the CEN DSRC stack as specified
in EN 15509, and Annexes C, D and E give the use of the Italian DSRC as specified in ETSI/ES 200 674-1,
ISO CALM IR, and ARIB DSRC.
This International Standard contains a protocol implementation conformance statement (PICS)
proforma in Annex B and informative transaction examples in Annex F. The informative Annex G
highlights how to use this International Standard for the European electronic toll service (as defined in
Commission Decision 2009/750/EC).
Test specifications are not within the scope of this International Standard.
