Public transport - Reference data model - Part 2: Public transport network

1.1   General Scope of the Standard
The main objective of the present standard is to present the Public Transport Reference Data Model based on:
-   the Public Transport Reference Data Model published 2006 as EN12896 and known as Trasmodel V5.1,
-   the model for the Identification of Fixed Objects for Public transport, published 2009 as EN 28701and known as IFOPT,
incorporating the requirements  of
-   EN15531-1 to 3 and TS15531-4 and 5: Service interface for real-time information relating to public transport operations (SIRI),
-   TS16614-1 and 2: Network and Timetable Exchange (NeTEx),
in particular the specific needs for long distance train operation.
Particular attention is drawn to the data model structure and methodology:
-   the data model is described in a modular form in order to facilitate understanding and 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.
This part corresponds to the network description as in Transmodel V5.1 extended by the relevant parts of IFOPT.
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)
-   Operations Monitoring and Control: operating day-related data, vehicle follow-up , control actions
-   Fare Management (fare structure and access rights definition, sales, validation, control)
-   Management Information and Statistics (including data dedicated to service performance indicators).
-   Driver Management:
-   Driver Scheduling (day-type related driver schedules),
-   Rostering (ordering of driver duties into sequences according to some chosen methods),
-   Driving Personnel Disposition (assignment of logical drivers to physical drivers and recording of driver performance).  
The data modules dedicated to cover most functions of the above domains will be 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.
1.3   Particular Scope of this Document
The present European Standard entitled Reference Data Model for Public Transport - Part 2 : Public Transport Network incorporates data structures which form the network topology description of Transmodel V5.1 and the major part of the fixed objects model of IFOPT. It is composed of three data packages:
-   Network Description,
-   Fixed Objects,
-   Tactical Planning Components.
The data structures represented in this part form network topology descriptions. They typically reference to structures as described in the Public Transport Reference Data Model - Part 1: Common Concepts", such as version frames or generic grouping mechanisms.
This document itself is composed of the following parts:
-   Main document (normative) representing the data model for the concepts shared by the different domains covered by Transmodel,

Javni prevoz - Referenčni podatkovni model - 2. del: Omrežje javnega prevoza

Glavni cilj trenutnega standarda je predstavitev referenčnega podatkovnega modela javnega prevoza na podlagi:
– referenčnega podatkovnega modela javnega prevoza, objavljenega leta 2006 kot standard EN12896 in poznanega kot Transmodel različice 5.1,
– modela za identifikacijo stalnih modelov za javni prevoz, objavljenega leta 2009 kot standard EN 28701 in poznanega kot IFOPT,
vsebuje zahteve
– standardov od EN15531-1 do 3 ter TS15531-4 in 5: Vmesnik za informiranje v realnem času za potrebe delovanja javnega prevoza (SIRI),
– standardov TS16614-1 in 2: Izmenjava omrežnih in voznorednih podatkov (NeTEx), predvsem specifične potrebe za obratovanje vlaka med kraji.
Posebna pozornost je namenjena strukturi podatkovnega modela in metodologiji:
– podatkovni model je opisan v modularni obliki za lažje razumevanje in uporabo modela,
– podatkovni model je v celoti opisan v UML.
Opisano je zlasti jedro referenčnega podatkovnega modela, ki se nanaša na podatkovno domeno:
– Opis omrežja: poti, linije, vzorci potovanj, časi potovanj, storitveni vzorci in načrtovana postajališča.
Ta del ustreza opisu omrežja v Transmodelu različice 5.1 in je razširjen z relevantnimi deli IFOPT.
Poleg tega so obravnavane naslednje funkcionalne domene:
– Časovni razpored in razpored vozil (vozni časi, poti vozil, dnevni razporedi vozil)  
– Informacije o potnikih (načrtovane in v realnem času)
– Vodenje in nadzor: dnevni podatki o obratovanju, spremljanje vozil, nadzorni ukrepi
– Upravljanje voznin (struktura voznin in pravice za dostop, prodaja, preverjanje, nadzor)
– Informacije o upravljanju in statistika (vključno s podatki, namenjenimi kazalcem uspešnosti storitev).
– Upravljanje voznikov:
– Razpored voznikov (dnevni razporedi voznikov),
– Urniki (razporejanje dolžnosti voznikov v zaporedje glede na nekatere izbrane metode),
– Razporejanje voznega osebja (dodelitev logičnih voznikov fizičnim voznikom in beleženje storilnosti voznika).  
Določeni bodo podatkovni modeli, ki bodo zajemali večino funkcij iz zgornjih domen. Različne funkcionalne domene imajo skupnih več konceptov. Ta podatkovna domena se imenuje Skupni koncepti.

European foreword
This document (EN 12896-2:2016) has been prepared by Technical Committee CEN/TC 278 “Intelligent
transport systems”, the secretariat of which is held by NEN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by March 2017, and conflicting national standards shall
be withdrawn at the latest by March 2017.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document together with documents EN 12896-1:2016 and EN 12896-3:2016 supersedes
EN 12896:2006.
The series composed of the following documents:
Public transport - Reference data model - Part 1: Common concepts
Public transport - Reference data model - Part 2: Public transport network
Public transport - Reference data model - Part 3: Timing information and vehicle scheduling
Public transport - Reference data model - Part 4: Operations monitoring and control
Public transport - Reference data model - Part 5: Fare management
Public transport - Reference Data model - Part 6: Passenger information
Public transport - Reference data model - Part 7: Driver management
Public transport - Reference data model - Part 8: Management information and statistics
Together these create version 6 of the European Standard EN 12896, known as “Transmodel” and thus
replace Transmodel V5.1.
The split into several documents intends to ease the task of users interested in particular functional
domains. Modularisation of Transmodel, undertaken within the NeTEx project, has contributed
significantly to this new edition of Transmodel.
In addition to the eight Parts of this European Standard an informative Technical Report (Public

1 Scope
1.1 General scope of the Standard
The main objective of the present Standard is to present the public transport reference data model
based on:
— the public transport reference data model published 2006 as EN 12896 and known as Transmodel
V5.1;

— rostering (ordering of driver duties into sequences according to some chosen methods);
— driving personnel disposition (assignment of logical drivers to physical drivers and
recording of driver performance).
The data modules dedicated to cover most functions of the above domains will be 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.
1.3 Particular Scope of this Document
The present European Standard entitled “Reference data model for Public transport – Part 2: Public
transport network” incorporates data structures which form the network topology description of
Transmodel V5.1 and the major part of the fixed objects model of IFOPT. It is composed of three data
packages:
— network description;
— fixed objects;
— tactical planning components.
The data structures represented in this part form network topology descriptions. They typically
reference to structures as described in the “Public transport - Reference data model - Part 1: Common
concepts”, such as version frames or generic grouping mechanisms.
This document itself is composed of the following parts:
— Main document (normative) representing the data model for the concepts shared by the different
domains covered by Transmodel;
— Annex A (normative), containing the data dictionary, i.e. the list of all the concepts and attribute
tables present in the main document together with the definitions;
— Annex B (informative), indicating the data model evolutions.

5 The Network Topology Domain
5.1 Introduction
The reference data model includes entity definitions for different types of points and links as the
building elements of the topological network. Stop points, timing points and route points, for instance,
reflect the different roles one point may have in the network definition: whether it is used for the
definition of (topological or geographical) routes, as a point served by vehicles when operating on a
line, or as a location against which timing information like departure, passing, or wait times are stored
in order to construct the timetables.
The line network is the fundamental infrastructure for the service offer, to be provided in the form of
vehicle journeys which passengers may use for their trips. The main entities describing the line
network in the reference data model are the line, the route and the journey pattern, which refer to the
concepts of an identified service offer to the public, the possible variants of itineraries vehicles would
follow when serving the line, and the (possibly different) successions of stop points served by the
vehicles when operating on the route.

The model delivers also a detailed geographical representation of stopping locations and related
concepts, such as equipment, access and navigation paths taken from the IFOPT standard and
harmonized with Transmodel within the NeTEx project., including the description of:
— the stops and stations at which transport is accessed together with accessibility characteristics;
— the points of interest from/to which passengers are travelling;
— the detailed navigation paths between the various locations and associated constraints;
— the equipment and services relevant for public transport actors;
— the parking locations relative to both stops and points of interest.
5.2 Model and document structure
The Network Topology models split into three main sub-models.
a) network description model (ND);
b) fixed object model (FO);
c) tactical planning components model (TP).
Network description model: describes infrastructure elements (different types of points and links)
and paths (routes and lines) dedicated to (regular and flexible) public transport operation; this
description may be considered as a macroscopic view of the network topological aspects of the
network. The model splits into:
— network infrastructure model;
— line network model;
— route model;
— flexible network model;
— activation model;
— vehicle and crew point model.
Fixed object model: describes geographical aspects of fixed elements such as stopping locations, or
points of interest. It represents, in particular, a detailed view of the stopping places, and associated
elements, such as services or equipment, but also concepts enabling the representation of the
navigation through or access to the stops. The model splits into:
— site model;
— stop place model;
— flexible stop place model;
— point of interest model;
— equipment description model;

SIST EN 12896-2:2017
EN 12896-2:2016 (E)
— path and navigation path model;
— check constraint model;
— parking model;
— vehicle stopping model;
Tactical planning components model: describes basic concepts related to the description of the work
patterns of public transport vehicles, such as journey patterns and service patterns, useful for planning
transport and some related aspects. This part describes the space-related aspects of the vehicle
services, whereas the time-related aspects (vehicle journeys, run times, etc) are described in Part 3 –
Timing Information and Vehicle Scheduling. The model splits into:
— journey pattern model;
— timing pattern model;
— service connection model;
— service pattern model;
— common section model;
— routing constraint model;
— time demand type model;
— stop assignment model;
— train stop assignment model;
— path assignment model;
— notice assignment model;
— passenger information display assignment model.
Explicit frames model: specific sets of “explicit“ VERSION FRAMES that specify sets of data elements
appropriate for a particular use case or set of related use cases.
The present document is structured according to the model structure as shown above with some
exceptions due to the necessity to introduce some concepts earlier in the document in order to ease the
understanding.
5.3 Network description model
5.3.1 Model overview
The network description model describes the basic physical network for transport and is itself divided
into a number of separate sub-models covering different aspects of the network:
— network infrastructure model:
— infrastructure network;
— network restriction;
10

SIST EN 12896-2:2017
EN 12896-2:2016 (E)
— main tactical planning points and links model (from the journey pattern model);
— activation model;
— vehicle and crew point model;
— line and route model;
— line network model;
— line network;
— line schematic map;
— flexible network model;
— flexible link, point and zone;
— flexible route;
— flexible line.
For ease of understanding, the sub-models are presented one at a time, each describing only a small set
of related concepts.
The sub-models depend on a number of general framework models (for example, generic point and link
model, notice model, etc.) described in the part “Public transport - Reference data model – Part 1:
Common concepts”.
5.3.2 Infrastructure Network
5.3.2.1 General
The infrastructure network model describes the physical network on which the transport services run;
a closely related network restriction model describes the physical restrictions on its use. This part does
not concern the service aspects, i.e. vehicle work patterns described separately (e.g. by TIMING
PATTERNs, JOURNEY PATTERNs, SERVICE PATTERNs).
5.3.2.2 Infrastructure Network– Conceptual Model
5.3.2.2.1 General
Figure 1 describes the main components of the physical path network (rail, roads, etc.).
This modelling of the infrastructure is, however, very basic and simple and is used here to represent
specific operational constraints (restrictions) for public transport operation resulting from the
characteristics of the INFRASTRUCTURE POINTs and LINKs and of VEHICLE TYPEs.The spatial detailed
organization of the infrastructure itself is described by other models (GDF, Inspire, etc.) and the data
are usually provided by GIS data sets.
