scope:

This standard specifies the application interface in the context of Electronic Fee Collection (EFC) systems using the Dedicated Short-Range Communication (DSRC). The EFC application interface is the EFC application process interface to the DSRC Application Layer, The scope of this standard comprises specifications of: - EFC attributes (i.e. EFC application information); - the addressing procedures of EFC attributes and (hardware) components (e.g. ICC and MMI); - 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.
