scope:

This International Standard defines requirements for short-rangecommunication for the purposes of compliance checking in autonomouselectronic fee-collecting systems. Compliance checkingcommunication (CCC) takes place between a road vehicle?s on-boardequipment (OBE) and an outside interrogator (road-side mountedequipment, mobile device or hand-held unit), and serves toestablish whether the data that are delivered by the OBE correctlyreflect the road usage of the corresponding vehicle according tothe rules of the pertinent toll regime. The operator of thecompliance checking interrogator is assumed to be part of the tollcharging role as defined in ISO 17573. The CCC permitsidentification of the OBE, vehicle and contract, and verificationof whether the driver has fulfilled his obligations and thechecking status and performance of the OBE. The CCC reads, but doesnot write, OBE data. This International Standard is applicable toOBE in an autonomous mode of operation; it is not applicable tocompliance checking in dedicated short-range communication(DSRC)-based charging systems. It defines data syntax andsemantics, but does not define a communication sequence. All theattributes defined herein are required in any OBE claimed to becompliant with this International Standard, even if some values areset to ?not defined? in cases where certain functionality is notpresent in an OBE. The interrogator is free to choose whichattributes are read, as well as the sequence in which they areread. In order to achieve compatibility with existing systems, thecommunication makes use of the attributes defined in ISO 14906wherever useful. The CCC is suitable for a range of short-rangecommunication media. Specific definitions are given for theCEN-DSRC as specified in EN 15509, as well as for the use of ISOCALM IR, the Italian DSRC as specified in ETSI ES 200 674-1 andARIB DSRC as alternatives to the CEN-DSRC. The attributes andfunctions defined are for compliance checking by means of the DSRCcommunication services provided by DSRC layer 7, with the CCCattributes and functions made available to the CCC applications atthe road-side equipment (RSE) and OBE. The attributes and functionsare defined on the level of application data units (ADU). Thedefinition of the CCC includes: ? the application interface betweenOBE and RSE (as depicted in Figure 2), ? use of the generic DSRCapplication layer as specified in ISO 15628 and EN 12834, ? use ofthe CEN-DSRC stack as specified in EN 15509, or other equivalentDSRC stacks as described in Annexes C, D and E, and ? securityservices for mutual authentication of the communication partnersand for signing of data (see Annex G). CCC data type specificationsare given in Annex A, protocol implementation conformance statement(PICS) proforma in Annex B. An example CCC transaction is presentedin Annex F. The informative Annex H highlights how to use thisInternational Standard for the European electronic toll service (asdefined in Commission Decision 2009/750/EC). Test specificationsare not within the scope of this International Standard.
