Electronic fee collection — Application interface definition for dedicated short-range communication
This document specifies the application interface in the context of electronic fee collection (EFC) systems using dedicated short-range communication (DSRC).
The EFC application interface is the EFC application process interface to the DSRC application layer, as can be seen in Figure 1. This document comprises specifications of:
— EFC attributes (i.e. EFC application information) that can also be used for other applications and/or interfaces;
— the addressing procedures of EFC attributes and (hardware) components (e.g. integrated circuit(s) card);
— EFC application functions, i.e. further qualification of actions by definitions of the concerned services, assignment of associated ActionType values, and content and meaning of action parameters;
— the EFC transaction model, which defines the common elements and steps of any EFC transaction;
— the behaviour of the interface so as to ensure interoperability on an EFC-DSRC application interface level.
This is an interface standard, adhering to the open systems interconnection (OSI) philosophy (see ISO/IEC 7498-
