Description of PD CEN/TR 16690:2014 2014

This Technical Report (TR) contains an analysis of the technical and operational feasibility of using a generic ITS Station as specified in ETSI EN 302 665, Intelligent Transport Systems (ITS); Communications Architecture, for EFC applications compliant to the requirements specified in ISO 17573, EN ISO 12855, CEN ISO/TS 17575 (all parts), EN ISO 14906, EN 15509, CEN ISO/TS 12813, CEN ISO/TS 13141 and CEN/TS 16439.

The scope of this Technical Report includes:

• description of the context of Cooperative ITS and the ITS Stations;

• providing details of the context of EFC applications;

• outlining the basic architectural concepts and role model of both EFC and Cooperative ITS;

• identification of core requirement areas for operation of an EFC application on an ITS Station;

• specification of a set of recommendations for functional, operational and security requirements to the ITS Station supporting the EFC application(s);

• description of a possible role model in which the roles known in EFC applications make use of the roles in the C-ITS system in order to provide EFC services in an C-ITS context;

• provision of considerations in particular areas of EFC like certification and governances;

• guideless and recommendations for further standardization work in this area;

• emphasizing on security related elements of EFC that need to be considered in a C-ITS environment.

The scope of this Technical Report is limited to in-vehicle ITS Stations. However, an EFC service always requires the involvement of in-vehicle and central functionalities. Furthermore, for enforcement purposes as well as in DSRC based toll domains for toll charging purposes also, it is essential that road-side based functions are provided and operated. In order to facilitate EFC services a set of functionalities, tasks and responsibilities are defined and specified in an EFC role model (ISO 17573). These functionalities, tasks and responsibilities are shared between the roles Toll Charger, Toll Service Provider, Road User and Interoperability Management. All these roles interact with each other. As a consequence this Technical Report provides in various areas explanations that are beyond the in-vehicle environment. This is required in order to present the full environment and context. It keeps the readability of this document at a sound level and provides valuable information to those readers which are not yet familiar with EFC in detail.

Outside the scope of this Technical Report is:

• detailed technical specifications for EFC services and applications on C-ITS systems;

• implementation specific elements.
