1 Scope
This Technical Specification defines an application interface between DSRC-based OBE and external in-vehicle devices to make DSRC- OBE applicable for diversified tolling environment.
The scope of this Technical Specification covers the following items (also shown in
Figure 2);
— Definitions of the application interface between DSRC- OBE and external in-vehicle devices (including GNSS, cellular units, CAN interface, etc.).
— Definitions of message sets and data elements on the interface (based on a sets of
base standards, such as ISO 14906:2011, ISO/TS 17575, ISO/TS 13141, ISO/TS 12813, and ISO/TS 25110).
— For use in autonomous EFC systems, as well as DSRC-based EFC.
— For use in diversified tolling environment (in toll roads, inner-urban, inter-urban,
etc.).
— For use in every kind of DSRC- OBE (based on CEN, UNI, ARIB, TTA, and GB/T).
The following items are out of the scope for this TS:
