Description / Abstract:
This International Standard defines requirements for short-range
communication for the purposes of compliance checking in autonomous
electronic fee-collecting systems. Compliance checking
communication (CCC) takes place between a road vehicle's on-board
equipment (OBE) and an outside interrogator (road side mounted
equipment, mobile device or hand-held unit), and serves to
establish whether the data that are delivered by the OBE correctly
reflect the road usage of the corresponding vehicle according to
the rules of the pertinent toll regime.
The operator of the compliance checking interrogator is assumed
to be part of the toll charging role as defined in ISO 17573. The
CCC permits identification of the OBE, vehicle and contract, and
verification of whether the driver has fulfilled his obligations
and the checking status and performance of the OBE. The CCC reads,
but does not write, OBE data.
This International Standard is applicable to OBE in an
autonomous mode of operation; it is not applicable to compliance
checking in dedicated short-range communication (DSRC)-based
charging systems.
It defines data syntax and semantics, but does not define a
communication sequence. All the attributes defined herein are
required in any OBE claimed to be compliant with this International
Standard, even if some values are set to "not defined" in cases
where certain functionality is not present in an OBE. The
interrogator is free to choose which attributes are read, as well
as the sequence in which they are read. In order to achieve
compatibility with existing systems, the communication makes use of
the attributes defined in ISO 14906 wherever useful.
The CCC is suitable for a range of short-range communication
media. Specific definitions are given for the CEN-DSRC as specified
in EN 15509, as well as for the use of ISO CALM IR, the Italian
DSRC as specified in ETSI ES 200 674-1 and ARIB DSRC as
alternatives to the CEN-DSRC. The attributes and functions defined
are for compliance checking by means of the DSRC communication
services provided by DSRC layer 7, with the CCC attributes and
functions made available to the CCC applications at the road side
equipment (RSE) and OBE. The attributes and functions are defined
on the level of application data units (ADU).
The definition of the CCC includes:
— the application interface between OBE and RSE (as depicted in
Figure 2),
— use of the generic DSRC application layer as specified in ISO
15628 and EN 12834,
— use of the CEN-DSRC stack as specified in EN 15509, or other
equivalent DSRC stacks as described in Annexes C, D and E, and
— security services for mutual authentication of the
communication partners and for signing of data (see Annex G).
CCC data type specifications are given in Annex A, protocol
implementation conformance statement (PICS) proforma in Annex B. An
example CCC transaction is presented in Annex F. The informative
Annex H highlights how to use this International Standard for the
European electronic toll service (as defined in Commission Decision
2009/750/EC).
Test specifications are not within the scope of this
International Standard.
