scope:

The scope for this document is limited to:

- payment method: Central account based on EFC-DSRC;

- physical systems: on-board unit (OBU), roadside equipment (RSE) and the DSRC interface between them (all functions and information flows related to these parts);

- DSRC-link requirements;

- EFC transactions over the DSRC interface;

- data elements to be used by OBU and RSE used in EFC-DSRC transactions;

- security mechanisms for OBU and RSE used in EFC-DSRC transactions.

It is outside the scope of this document to define:

- contractual and procedural interoperability requirements (including issues related to a memorandum of understanding, MoU);

- conformance procedures and test specifications;

- setting-up of operating organizations (e.g. toll charger, toll service provider, trusted third party, etc.);

- legal issues;

- other payment methods in DSRC-based EFC (e.g. on-board accounts using integrated circuit cards);

- other basic technologies (e.g. GNSS/CN or video registration-based EFC). However, this document may be used for defining the DSRC-EFC parts for the use in applications that implement a mix of different technologies;

- non-EFC transactions over the DSRC interface (e.g. compliance check communication and localization augmentation communication, which are defined in other standards);

- other interfaces or functions in EFC-systems than those specified above (i.e. information flows and data exchange between operators or personalization, initialization and customization of the OBU).

NOTE Some of the issues that are outside the scope of this document are subject of separate standards prepared by CEN/TC 278, ISO/TC 204 and ETSI ERM.
