Road user charging in transport is used across Europe for raising revenue, dealing with congestion and internalising transport costs. Concerns over escalating congestion, pollution and carbon dioxide issues, i.e. the sustainability of road transport, put even more emphasis on fair road pricing schemes in Europe.
Electronic Fee Collection (EFC) is an overall notion used to designate ICT solutions that automatically, and without stopping, collect road user charges. EFC systems allow effective charging of road vehicles and support a broad variety of pricing policies. There are three main technologies used in EFC today:
There are many EFC systems in Europe today. However, most of them have been developed and expanded on a regional basis creating different variants between different nations. In order to reap the full benefits of EFC systems they need to be interoperable, allowing a vehicle to pay charges in different countries using a single on-board equipment (OBE) and a single contract.
For this reason European regulations have been adopted (i.e. Directive 2004/52/EC, EC Decision 2009/750/EC and Directive (EU) 2019/520) that set out to create a European electronic toll service (EETS). Interested EETS users must be provided with the option to sign up for a single subscription contract and OBE with an EETS Service Provider of his choice, giving them access to the service on the whole of the road network in the entire Community.
EFC standards provide solid technical support for agreements between stakeholders and form a foundation for the interoperability between EFC systems. Overall the standardisation of EFC contributes to improving circulation of goods, services and people in Europe.
CEN/TC278/WG1 is responsible for European standardising of the EFC application, whilst other international standardisation groups develop technology-related standards (such as GNSS and communication protocols). Most EFC standards are developed as joint work items with ISO (TC 204/WG5). In addition ETSI provides certain technical standards on testing that are important for EFC.
The current standardisation work includes defining application interfaces between equipment, information flows between EFC operators, architecture, security, conformance evaluation and test standards, personalisation of OBE, performance indicators and enforcement/monitoring support.
Standardisation in WG1 is divided into the following areas:
CEN and ETSI are working closely together with the EC on standards that will underpin the EETS, under the EC Mandate M/338. WG1 develops the standards that form the main technical building blocks for defining this interoperable service, and supports the notified bodies EETS coordination group (NB EETS CG). Much of the standardisation work undertaken builds on the work from European EFC projects, such as CARDME, CESARE-4, PISTA, MEDIA, RCI and REETS.
