This document 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 document specifies the provision of location and heading information and security means to protect against the manipulation of the OBE with false RSE.

The localization augmentation communication (LAC) takes place between an OBE in a vehicle and fixed RSE. This document is applicable to OBE in an autonomous mode of operation.

This document specifies attributes and functions for the purpose of localization augmentation, by making use of the dedicated short-range communications (DSRC) communication services provided by DSRC Layer7, and makes these LAC attributes and functions available to the LAC applications at the RSE and the OBE. Attributes and functions are specified on the level of application data units (ADUs; see Figure1).

As depicted in Figure1, this document is applicable to:

the use of the DSRC stack.

The LAC is suitable for a range of short-range communication media. This document provides specific definitions regarding the CEN-DSRC stack as specified in EN15509. AnnexesC, D, E and H provide for the use of the Italian DSRC as specified in ETSI/ES 200 674-1,ISO CALM IRARIB DSRCand WAVE DSRC.

This document contains a protocol implementation conformance statement (PICS) proforma in AnnexB and transaction examples in AnnexF. AnnexG highlights how to use this document for the European Electronic Toll Service (EETS).

Test specifications are not within the scope of this document.
