ISO 12855:2022

Description

This document specifies:

-    the interfaces between electronic fee collection (EFC) back-office systems for vehicle-related transport services, e.g. road user charging, parking and access control;

-    an exchange of information between the back end system 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.

This document is applicable for any vehicle-related toll service and any technology used for charging.

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 specifies basic protocol mechanisms over which implementations can specify and perform complex transfers (transactions).

This document does not specify, amongst others:

-    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;

-    interfaces for EFC systems for public transport;

-    any complex transfers (transactions), i.e. sequences of inter-related application data units (ADUs) that can possibly involve several application protocol data unit (APDU) exchanges;

-    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.
