16614 (NeTEx) is composed of a series of standards: - Part 1: Description of the public transport network topology exchange format. - Part 2: Description of the scheduled timetables exchange format. - Part 3: Description of the fare information exchange format. - Part 4: Description of the passenger information European profile (EPIP). - Part 5: Description of the alternative modes exchange format. - Part 6: Description of the accessibility European profile (EPIAP). The present update concerns Part 5. All the parts will be updated together, except Part 6 currently under formal vote (a NWI is produced for each Part). This update is done in a similar timeframe as the Transmodel (EN12896) revision, to achieve the best possible consistency. The updated version of TS 16614 is going to be published as NeTEx v2. The global updates consist in the following main extensions/enhancements: - Deck plan allowing for a digitalised representation of spaces and equipment on board vehicles (with considerations of accessibility features), - Physical layout of compound vehicles (e.g. train composition), - Multiple minor enhancements, adjustments, and fixes to consider all the feedback from the previous versions of NeTEx, especially in the context of the European Delegated Regulation EU 2017/1926 Consistency and coherences with Transmodel and SIRI and OJP have also been challenged and minor updates are to be integrated in this revision. This Part 5 of NeTEx is specifically concerned with the exchange of reference data to support new alternative modes for mobility services, adding certain new concepts to the NeTEx schema (indicated as NeTEx v1.2.2), but also to a high degree making use of existing schema elements defined in NeTEx Parts 1, 2 and 3. The high-level design for alternative modes support is derived from a conceptual model for alternative modes CEN/TS 17413:2020 prepared by CEN working group TC278 WG17. This CEN Technical Specification describes a conceptual model for alternative modes as an extension to Transmodel V6.0 and based on a detailed set of use cases taken from CEN/TS 17413:2020, and given in Appendix A. The NeTEx format is concerned with a subset of the use cases for reference data (real-time use cases are covered by dynamic protocols such as SIRI and DATEX II). Overall, it is concerned with data for the following purposes: to be able to integrate legs made on alternative modes with conventional mode legs in seamless trip plans; to describe the coverage areas of alternative mode mobility services so that trip planning engines and others can make passengers aware of the possibility of using them, and provide appropriate links to invoke the dynamic services; to be able to find the locations of access points for alternative mode services, such as parking points, pooling stations, etc. including their relation to access points for conventional modes; to be able to indicate the costs of the mobility services for specific trip legs. Where operators offer a bundle of modes services (for example free cycle use with metro use) to be able to include the fare product for alternative mode legs in the sales offer; to be able to indicate how to book, purchase and pay for mobility services, and how to access them. NeTEx is primarily concerned with the exchange of reference data to allow the integration of new modes with other data; it does not describe dynamic services. CEN/TS 17413:2020 specification indicates the nature of some of these services such as trip planning.
