The scope for this European Standard is limited to:
— payment method: Central account based on EFC-DSRC;
— physical systems: OBU, 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.
— contractual and procedural interoperability requirements (including issues related to a Memorandum of Understanding, MoU);
— conformance procedures and test specification (this is provided in a separate set of standards);
— 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 European Standard 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. CCC and LAC communication, which is 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).
