— 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.

— contractual and procedural interoperability requirements;

— conformance procedures and test specifications;

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

— 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);

— non-EFC transactions over the DSRC interface (e.g. compliance check communication and localization augmentation communication, which are specified 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).
