NF EN ISO 12813, P99-415 (03/2024)

This document specifies requirements for short-range communications for the purposes of compliance monitoring in autonomous electronic toll collection systems. Compliance Checking Communication (CCC) occurs between the on-board equipment of a road vehicle (OBE) and an interrogator (fixed and mobile roadside equipment (RSE) or portable device) and makes it possible to determine whether the data provided by the on-board equipment correctly reflects the use of the road network by the corresponding vehicle according to the rules of the applicable toll regime. The operator of the Compliance Check Interrogator is assumed to participate in the Toll Collection role defined in ISO 17573-1. The CCC application makes it possible to identify the on-board equipment, the vehicle and the contract, to verify that the driver has fulfilled his obligations and to determine the operating status and performance of the on-board equipment. The CCC application reads, but does not write data from on-board equipment. This document applies to autonomous on-board equipment; it does not apply to compliance monitoring in charging systems based on dedicated short-range communications (DSRC). It specifies the syntax and semantics of the data, but does not define a communication sequence. All attributes specified therein are required in any on-board equipment claimed to conform to this document, even if some values are specified as "not specified" in cases where a certain functionality is not present in a given on-board equipment. The interrogator is free to choose which attributes are read, as well as the order in which they are read. To enable compatibility with existing systems, communication uses the attributes specified in ISO 17573-3 wherever useful. The CCC application is suitable for a variety of short-range communications media. Specific definitions are given for the CEN-DSRC communications stack specified in EN 15509, as well as for the use of the ISO CALM IR, UNI DSRC (ETSI ES 200 674-1), ARIB DSRC and WAVE DSRC stacks as alternatives at CEN-DSRC. The specified attributes and functions are intended for compliance monitoring via DSRC communication services provided by the DSRC application layer, using CCC attributes and functions made available to CCC applications on roadside equipment (RSE, Road-Side Equipment) and on-board equipment. Attributes and functions are specified at the Application Data Unit (ADU) level. The definition of CCC communication includes: — the application interface between the OBE and the RSE (as described in Figure 2); — the use of the generic DSRC application layer specified in ISO 15628 and EN 12834; — the CCC data type specifications given in Annex A; — a Protocol Implementation Conformance Statement (PICS) form is provided in Annex B; — the use of the CEN-DSRC stack according to EN 15509 or other equivalent DSRC communications stacks as described in Annex C, Annex D, Annex E and Annex F; — security services in the context of mutual authentication of communication partners and data signing (see Annex H); Additionally, an example of a CCC transaction is presented in Annex G and Annex I explains how to use this document within the framework of the European Electronic Toll Service (ETS). Test specifications are outside the scope of this document.
