UNE-EN ISO 12855:2022

This document 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.

charging related data (toll declarations, billing details),

administrative data, and

confirmation data,

transfer mechanisms and supporting functions,

information objects, data syntax and semantics,

examples of data interchanges (see Annex B and Annex C), and

an example of toll rounding (see Annex D).

This document 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 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.

This document is not applicable, among others, to

any communication between toll charger (TC) or toll service provider (TSP) with any other involved party,

any communication between elements of the TC and the TSP that is not part of the back office communication,

processes regarding payments and exchanges of fiscal, commercial or legal accounting documents, and

definitions of service communication channels, protocols and service primitives to transfer the APDUs.
