scope:

This Technical Specification defines a set of interoperable application profiles suitable to be used defining the overall functionality of an interoperable EFC cluster using autonomous vehicle equipment. Doing so, it also defines a way of defining further profiles for future use.

The profiles cover a wide range from simple toll road systems up to very complex tolling principles and tariff rules. An EFC cluster shall select and use one of these profiles covering the needs of all participating Toll Chargers.

The scope is limited to those base standards providing data elements or messages to be used specifically when defining the data exchange for autonomous tolling principles.

This covers ISO 17573 and the base standards CEN ISO/TS 17575 parts 1 to 4, CEN ISO/TS 12813, CEN ISO/TS 13141 and those parts of EN ISO 12855 specifying messages which are only relevant for autonomous systems.

For each specified profile, the conditional requirements resulting from the actual use of data elements being still optional according to this profile are specified in Annex A. A set of rules on how to re-use identifiers of a specific entity within the full chain of transactions is specified in Annex B and a protocol implementation conformance statement (PICS) proforma in Annex C.

Figure 3 provides a graphical illustration of the scope of this Interoperable Application Profile which is based on the ISP concept according to ISO IEC/TR 10000-1.

Outside of the scope are:

- details on how to achieve security using the authenticator data elements of the base standards;

- how to operate the enforcement process;

- commercial aspects and the billing process;

- the handling of DSRC charging transactions;

- system monitoring and performance indicators;

- test standards;

- the initial configuration of the OBE.
