Full Description

ISO 12855:2015 specifies

- the interfaces between electronic fee collection (EFC) systems for vehicle related transport services, e.g. road user charging, parking and access control; it does not cover interfaces for EFC systems for public transport; an EFC system can include any EFC system, e.g. including systems that automatically read licence plate numbers of vehicles passing a toll point,

- an exchange of information between the central equipment of the two roles of service provision and toll charging, e.g.

- transfer mechanisms and supporting functions,

- information objects, data syntax and semantics,

- examples of data interchanges (see Annex C and Annex D), and

- an example on how to use this International Standard for the European Electronic Tolling Service (EETS) (see Annex F).

ISO 12855:2015 is applicable for any toll service and any technology used for charging.

It is defined as a toolbox standard of transactions and Application Protocol Data Units (APDUs), which can be used for the assigned purpose. The detailed definitions of mandatory and optional elements in a real implementation are defined elsewhere. It does not define all communication sequences, communication stacks and timings.

The scope of ISO 12855:2015 is illustrated in Figure 2. The data types and associated coding related to the data elements described in Clause 6 are defined in Annex A, using the abstract syntax notation one (ASN.1) according to ISO/IEC 8824-1.
