Electronic fee collection - Measurement of interferences on tolling and tachograph devices from radio local area network devices operating in the 5,8 GHz frequency range - Test suite structure and test purposes
kSIST-TS FprCEN/TS 18078:2024

This document specifies the set-up of a testing system and the test suite structure and test purposes, i.e. tests to be used to assess the level of interference from RLAN devices operating in the 5,8 GHz range on tolling and tachograph devices operating in the same frequency range.
To obtain generalized results that can subsequently be used to design appropriate mitigation techniques, the test environment and the test cases are designed to:
1.   acquire a large number of transactions on devices of different makes and characteristics;
2.   ensure anonymity of results.
The test results ensure calculation of averages as well as standard deviations.
The tests specified in this document are for the sole purpose of investigating RLAN interference over DSRC communications. Other factors that can impact the performance of DSRC and also the level of interference in a test scenario are not subject to test specifications and out of the scope of this document.

Intelligent transport systems - Cooperative ITS - Dictionary of in-vehicle information (IVI) data structures (ISO/TS 19321:2024)
SIST-TS CEN ISO/TS 19321:2024

This document specifies the in-vehicle information (IVI) data structures that are required by different intelligent transport system (ITS) services for exchanging information between ITS stations (ITS-S). A general, extensible data structure is specified, which is split into structures called containers to accommodate current-day information. Transmitted information includes IVI such as contextual speed, road works warnings, vehicle restrictions, lane restrictions, road hazard warnings, location-based services and re-routing. The information in the containers is organized in sub-structures called data frames and data elements, which are described in terms of their content and syntax.
The data structures are specified as communications-agnostic. This document does not provide the communication protocols. This document provides scenarios for usage of the data structure, e.g. in case of real time, short-range communications.

Public transport - Network and timetable exchange (NeTEx) - Part 6: European Passenger Information Accessibility Profile
SIST-TS CEN/TS 16614-6:2024

This document is a profile of the CEN/TS 16614 series. It focuses on information relevant to feed the necessary accessibility passenger information services and excludes operational and fares information. It is based directly on EPIP (CEN/TS 16614-4).
This European Passenger Information Accessibility Profile (EPIAP) for NeTEx is for exchanging passenger information; it describes how to extend EPIP (the European Passenger Information Profile) with additional information (including a minimal set) to feed the necessary accessibility passenger information services in a European wide and multimodal context. EPIAP especially formulates a mandatory minimal implementation that needs to be filled in by everybody to deliver the necessary information for an assessment of the accessibility of site(s), vehicles and on vehicle-site interaction for impaired persons. The minimal level allows an assessment and contains the information to produce PRM TSI if necessary. It will also cover what the current legislation usually warrants. It then describes how additional information must be provided if an organisation decides to provide it (e.g. the information of the full DELFI+ standard in Germany).
EPIP does not reflect part 5 (New Modes) yet. However, EPIAP takes it into account. EPIP will have to be adapted accordingly.
For EPIAP to be of use, the EC needs to declare the minimal level of EPIAP as mandatory.

Electronic fee collection - Localization augmentation communication for autonomous systems (ISO 13141:2024)
SIST EN ISO 13141:2024

This document establishes requirements for short-range communication for the purposes of augmenting the localization in autonomous electronic fee collection (EFC) systems. Localization augmentation serves to inform on-board equipment (OBE) about geographical location and the identification of a charge object. This document specifies the provision of location and heading information and security means to protect against the manipulation of the OBE with false RSE.
The localization augmentation communication (LAC) takes place between an OBE in a vehicle and fixed RSE. This document is applicable to OBE in an autonomous mode of operation.
This document specifies attributes and functions for the purpose of localization augmentation, by making use of the dedicated short-range communications (DSRC) communication services provided by DSRC Layer 7, and makes these LAC attributes and functions available to the LAC applications at the RSE and the OBE. Attributes and functions are specified on the level of application data units (ADUs; see Figure 1).
As depicted in Figure 1, this document is applicable to:
—     the application interface definition between OBE and RSE;
—     the interface to the DSRC application layer, as specified in ISO 15628 and EN 12834;
—     the use of the DSRC stack.
The LAC is suitable for a range of short-range communication media. This document provides specific definitions regarding the CEN-DSRC stack as specified in EN 15509. Annexes C, D, E and H provide for the use of the Italian DSRC as specified in ETSI/ES 200 674-1, ISO CALM IR ARIB DSRC and WAVE DSRC.
This document contains a protocol implementation conformance statement (PICS) proforma in Annex B and transaction examples in Annex F. Annex G highlights how to use this document for the European Electronic Toll Service (EETS).
Test specifications are not within the scope of this document.

Electronic fee collection - Compliance check communication for autonomous systems (ISO 12813:2024)
SIST EN ISO 12813:2024

This document specifies 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 interrogator [fixed and mobile roadside equipment (RSE) 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 17573-1. The CCC permits identification of the OBE, vehicle and contract, and verification of whether the driver has fulfilled their obligations and the checking status and performance of the OBE. The CCC reads, but does not write, OBE data.
This document 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 specifies data syntax and semantics, but not a communication sequence. All the attributes specified herein are required in any OBE claimed to be compliant with this document, even if some values are set to “not specified” in cases where a certain functionality is not present in an OBE. The interrogator is free to choose which attributes are read in the data retrieval phase, 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 specified in ISO 17573-3 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, ARIB DSRC, and WAVE DSRC as alternatives to the CEN-DSRC. The attributes and functions specified are for compliance checking by means of the DSRC communication services provided by DSRC application layer, with the CCC attributes and functions made available to the CCC applications at the RSE and OBE. The attributes and functions are specified on the level of application data units (ADUs).
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;
—     CCC data type specifications given in Annex A;
—     a protocol implementation conformance statement (PICS) proforma is given in Annex B;
—     use of the CEN-DSRC stack as specified in EN 15509, or other equivalent DSRC stacks as described in Annex C, Annex D, Annex E and Annex F;
—     security services for mutual authentication of the communication partners and for signing of data (see Annex H);
In addition, an example CCC transaction is presented in Annex G and Annex I highlights how to use this document for the European Electronic Toll Service (EETS).
Test specifications are not within the scope of this document.
