1.1. General scope The main objective of the present standard is to present the Reference Data Model for Public Transport, based on: " the Reference Data Model, EN12896, known as Transmodel V6, incorporating the requirements of " EN 15531-1 to -3 and TS 15531-4 and -5: Service interface for real-time information relating to public transport operations (SIRI), " TS 16614-1 to 5: Network and Timetable Exchange (NeTEx). A particular attention is drawn to the data model structure and methodology: " the data model is described in a modular form in order to facilitate the understanding and the use of the model, " the data model is entirely described in UML. In particular, a Reference Data Model kernel is described, referring to the data domain: " Network Description: routes, lines, journey patterns, timing patterns, service patterns, scheduled stop points and stop places. Furthermore, the following functional domains are considered: " Timing Information and Vehicle Scheduling (runtimes, vehicle journeys, day type-related vehicle schedules) " Passenger Information (planned and real-time) " Fare Management (fare structure, sales, validation, control) " Operations Monitoring and Control: operating day-related data, vehicle follow-up , control actions " Management Information and Statistics (including data dedicated to service performance indicators). " Driver Management: o Driver Scheduling (day-type related driver schedules), o Rostering (ordering of driver duties into sequences according to some chosen methods), o Driving Personnel Disposition (assignment of logical drivers to physical drivers and recording of driver performance). This part corresponds to the Transmodel V6.0 Alternative Modes The data modules dedicated to cover most functions of the above domains are specified. Several concepts are shared by the different functional domains. This data domain is called Common Concepts . 1.2 Functional Domain Description The different functional domains taken into account in the present standard and of which the data have been represented as the reference data model are described in Public Transport Reference Data Model - Part 1: Common Concepts . They are: " Public Transport Network and Stop Description " Timing Information and Vehicle scheduling " Passenger information " Fare Management " Operations monitoring and control " Management information " Personnel Management: Driver Scheduling, Rostering, Personnel Disposition. The aspects of multi-modal operation and multiple operators environment are also taken into account. The functional domains related to the present document are described in chapter 5 below. 1.3 Particular Scope of this Document This document defines new modes in a reference data model, in order to allow integration of these modes into urban multimodal travel services (e.g., trip planning systems).
