Overview
SIST EN ISO 12855:2022 establishes the framework for information exchange between service provision and toll charging in electronic fee collection (EFC) systems for vehicle-related transport services. It standardizes how back-office systems of toll chargers (TC) and toll service providers (TSP) communicate for services such as road user charging, parking, and access control.
The standard connects operational and administrative data flow, enabling both parties to efficiently exchange critical information related to charging, billing, and confirmations. By providing a universal set of definitions, data syntax, protocol mechanisms, and supporting functions, SIST EN ISO 12855:2022 facilitates technical interoperability among EFC systems using any charging technology.
Key Topics
- Back-Office System Interfaces: Defines standardized interfaces for communication between EFC back-office systems operated by TCs and TSPs.
- Data Exchange Types: Specifies charging-related data (e.g., toll declarations, billing details), administrative information, and confirmation data shared between parties.
- Protocol Mechanisms: Outlines the use of application protocol data units (APDUs) and basic protocol mechanisms that allow implementations to perform reliable data transfers, including request, acknowledge, and status messages.
- Data Structures and Semantics: Details the structure, syntax, and semantics of information objects to ensure data consistency and integrity.
- Transfer and Security: Describes mechanisms for secure and efficient data transfer, including supporting functions for authentication and encryption.
- Interoperability Support: Highlights the ability to accommodate any vehicle-related toll service or charging technology, promoting interoperability across varied operational environments.
Applications
SIST EN ISO 12855:2022 is applicable for organizations involved in electronic toll collection and service provision for vehicle-related transport. Its scope includes, but is not limited to:
- Road User Charging: Standardizes data communication between toll road operators and third-party service providers overseeing user accounts and transactions.
- Parking and Access Control: Enables interoperability of parking fee systems and restricted access controls, coordinating billing and confirmations with centralized back-office systems.
- Infrastructural Projects: Useful in multi-operator toll domains, such as cross-border or pan-European road networks, facilitating a single contractual framework for users and integrated settlement for operators.
- Technology Integration: Supports any technology for tolling, such as DSRC or GNSS-based systems, aligning with EU directives for EFC interoperability.
- Quality Assurance and Enforcement: Provides mechanisms for exchanging quality assurance parameters, compliance events, and exception handling, enhancing system reliability and user satisfaction.
Related Standards
To ensure broad compatibility and integration, SIST EN ISO 12855:2022 references several international standards, including:
- ISO 17573-1: System architecture for vehicle-related tolling, forming the foundational model for EFC service roles and data exchange.
- ISO 14906: Application interface for dedicated short-range communication (DSRC) in electronic fee collection.
- ISO/IEC 8824-1: Abstract Syntax Notation One (ASN.1) for standardized data encoding.
- ISO/TS 17573-2: Vocabulary for EFC system architecture.
- ISO 19299: Security framework for electronic fee collection.
- CEN/TS 16986: Interoperable application profiles supporting pan-European tolling solutions.
Practical Value
By implementing SIST EN ISO 12855:2022, toll service providers and toll chargers ensure a harmonized approach to information exchange, critical for efficiency, scalability, and compliance. The standard underpins seamless interoperability, reduces integration complexity, and supports the development of cross-border or multi-technology tolling infrastructures. Stakeholders benefit from clearer data flows, improved security, enhanced system reliability, and future-proofing for evolving transport technologies.
