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.
