TESTING PROCEDURES FOR COMPLIANCE ASSESSMENT

D.1   SELF-ASSESSMENT AND EVIDENCE-BASED DECLARATION FOR INDIVIDUAL IT MESSAGES

• (1) The telematics applications used by telematics stakeholders for the implementation of this Regulation shall be subject to a self-assessment of the compliance of the data shared against the requirements laid down in the Regulation. Self-assessment performed by telematics stakeholders and notified to the Agency in accordance with Article 18 shall be accompanied by the following information automatically compiled by the web application provided by the Agency:

• (a) functions covered and reference to corresponding points of this Regulation, including general and structured description of the telematics applications used in relation to those functions;

• (b) online documentation of messages (including their sequence) tested against the specifications referenced in the Regulation, and corresponding automated evidence-based declaration of compliance as referred to in point (6);

• (c) the version of the specifications referenced in Appendix C, as implemented and subject to compliance assessment;

• (d) files of the serialised messages and associated structured data elements shared as well as the SHACL or XSD files used to validate those messages.

• (2) For requests submitted to the Agency for correctness checks of the automated evidence-based declaration of compliance resulting from self-assessment in accordance with Article 18(8), the information referred to in subpoint (1) of this point shall also include background information and a timeline of the project to be assessed.

• (3) Where an existing self-assessment is to be renewed in accordance with Article 18(5), the self-assessment referred to in point (1) shall be limited to the elements affected by the changes self-assessed. The information compiled pursuant to point (1) shall also include a reference to the previous self-assessment or to the evaluation report delivered by the Agency in accordance with Article 18(7).

• (4) To facilitate the testing of messages referred to in point (1)(b) and their sequence, telematics stakeholders shall self-assess the compliance of individual messages deployed and used for the purposes of implementing this Regulation.

• (5) The Agency shall make available a web application for self-assessing message compliance where telematics stakeholders are to self-asses relevant files in accordance with point (1)(d) for automated testing against the specifications referenced in Appendix C, index [1].

• (6) After self-assessment, that web application shall issue an automated acknowledgment of receipt and a self-compliance assessment result to be used by the self-assessed telematics stakeholder as an evidence-based declaration of presumption of compliance for the messages or sequence of messages tested.

D.2   EVALUATION OF THE CORRECTNESS OF SELF-ASSESSMENT

• (1) Where the Agency checks, pursuant to Article 18, paragraphs 6, 7, and 8, the correctness of the automated evidence-based declaration of presumption of compliance resulting from self-assessment, it shall report its evaluation on whether the telematics application used complies with this TSI. Its evaluation report shall cover at least the following aspects:

• (a) compliance of all mandatory elements contained in the messages;

• (b) compliance of the messages themselves;

• (c) compliance of the sequence of messages.

D.3   SPECIFIC TESTING PROCEDURES FOR RAIL TICKETING

D.3.A   Passenger timetable

Testing procedures for assessment of compliance against the requirements laid down in point 4.2 of this Annex shall be in accordance with the specifications referenced in Appendix C, index [B.17].

D.3.B   Tariffs

• (1) Testing procedures for assessment of compliance against the requirements laid down in point 4.3 of this Annex are identified as an ‘open point’ in accordance with Article 4(6) of Directive (EU) 2016/797 and are listed in Appendix B to this Annex.

• (2) Pending the development of relevant testing procedures pursuant to Article 23, points (c) and (e), automatic converters and validators based on an open architecture may be used by telematics stakeholders to self-assess the compatibility and interoperability of the data shared and the processes implemented against the specifications set out in point 4.3.

D.3.C   Availability check and reservation

• (1) Testing procedures for assessment of compliance against the requirements laid down in point 4.5 of this Annex are identified as an ‘open point’ in accordance with Article 4(6) of Directive (EU) 2016/797 and are listed in Appendix B to this Annex.

• (2) Pending the development of relevant testing procedures pursuant to Article 23, points (c) and (e), automatic validators based on an open architecture may be used by telematics stakeholders to self-assess the compatibility and interoperability of the data shared and the processes implemented against the specifications set out in point 4.5.

Appendix E

ACCURACY OF FORECAST INFORMATION FOR TRAIN AND FREIGHT WAGON MOVEMENTS

(1)

Since the train forecast information referred to in point 2.6.4 and the wagon forecast information referred to in point 3.2.3 refer to the predicted time of arrival of a train and of a freight wagon and its load, respectively, at an agreed reporting point, it will be used by stakeholders and customers involved in the rail transport service to plan subsequent operations or onward connections.

(2)

Since both the train forecast information referred to in point 2.6.4 and the freight wagon forecast information referred to in point 3.2.3 are an estimate that derive from the time originally planned in the working timetable +/- the deviation from the working timetable that occurred during the train operation, the originator of such a forecast shall:

• (a) carry out an ex-post measurement of the accuracy of its forecast in accordance with Article 10 in order to create confidence in the data to be reused by the recipient for the planning of subsequent operation;

• (b) ensure that the recipient of the forecast referred to in point (a) is informed of the expected accuracy of the forecast based on earlier train runs.

(3)

As an alternative to linear time-shifting methods commonly applied by some telematics stakeholders for the purposes of point (2) (a), others may apply different methods or use internal algorithm-based machine learning methods that may be integrated into an artificial intelligence to achieve more accurate and intelligent insights.

(4)

For the purpose of point (2), recurrent quality assurance checks on the accuracy of forecast information are laid down as follows:

• (a) absolute error:

The ‘absolute error’ is calculated as the absolute value of the difference between the actual date and time of arrival at a specified reporting point and the forecast date and time of arrival at that reporting point;

• (b) relative error:

To put the ‘absolute error’ at a specified reporting point in perspective with the duration of the remaining train journey, a ‘relative error’ is calculated as the ratio or percentage obtained by dividing the ‘absolute error’ by the ‘duration of the remaining train journey’;

The ‘duration of the remaining train journey’ is calculated as the difference between the actual date and time of the arrival of a train at the reporting point and the time when the corresponding forecast information has been provided;

• (c) accuracy:

The ‘accuracy’ are calculated as the complement of the ‘relative error’ to 100 %.

(5)

Where a data holder, that is to say the originator of the data, performs recurrent quality assurance checks as referred to in point (3), it shall assess the accuracy of the data as a stochastic probability of the statistical values of the forecast information at a specified reporting point for a group composed of previous rail transport services.

(6)

A data holder shall perform quality assurance checks on the accuracy of train forecast information only once that train has arrived, or after that freight wagon and its load have been handed over or delivered at, the reporting point that is subject to the forecast. Quality assurance checks shall be based only on historical data.

(7)

Indicators resulting from the measurements referred to in point (3) shall be available through the common Union web UI referred to in Article 5.
