Introduction
This Technical Specification is Part 10 of a series of European Standards and Technical Specifications.
The scope of this series is on-board data communication systems on public transport vehicles.
Public Transport (PT) vehicles have an increasing array of information and communications systems,
including ticket machines, Automated Vehicle Location (AVL) systems, destination displays, passenger
announcement systems, vehicle monitoring systems, etc. Other systems are beginning to be included
such as advertising screens, tourist guides, WiFi “hotspots” and infotainment.
In addition, equipped PT vehicle will usually have a communications facility to enable voice and data to
be exchanged with the control centre, other PT vehicles, PT infrastructure and roadside devices for
instance in requesting priority at traffic signals. Many types of communication channel are used
including public and private wireless communication networks.
These systems may be provided by a number of different suppliers and may need to be integrated. For
instance:
— a ticket machine may need location information to update fare stages;
— next-stop and destination information may be drawn from schedule information held in the ticket
machine;
— vehicle location systems may be used to drive signal priority requests.
As data exchange between functional units becomes more widespread, a networked approach begins to
become efficient. With standardized underlying technology, the PT vehicle begins to look like a local
area network: making use of IEEE 802 communications and the Internet Protocol (IP) suite.
Without a clear technology framework, integrating these systems would require complex technical
discussions every time a device is procured. The existing EN 13149 standards recognized this long ago
in respect of the core vehicle systems, but these have not been adapted to IP networking.
Six historical parts of EN 13149, namely Parts 1 to 6, have now been withdrawn in favour of the new IP-
based approach. The core of this new approach was specified in two Technical Specifications (TS):
— CEN/TS 13149-7 specifies the Network and System Architecture for on board equipment. It
describes basic principles of communications including a general description of the network
topology, addresses schematics, basic network services, a system overview and basic module
architecture.
— CEN/TS 13149-8 specifies the Physical Layer for IP-communication networks on board PT vehicles.
This part specifies the cables, connectors and other equipment including pin assignment and
environmental requirements.
Building on this, a series of specific services are being specified:
— CEN/TS 13149-9, specifying the structure to be used by a service providing time data to the on-bus
network;
— CEN/TS 13149-10, specifying the structure to be used by a service providing location data to the
on-bus network, specifically relating to Global Navigational Satellite Systems (GNSS);
— CEN/TS 13149-11, specifying the structure to be used by a service providing data from the vehicle
platform to the on-bus network, using the Fleet Management System (FMS) for source data.
These documents draw on large scale trials undertaken within European projects such as EBSF (the
“European Bus System of the Future” project) and its successors, together with technical developments
which have since been adopted by programmes such as the German IBIS-IP platform [1] and, more
recently, the European platform ITxPT [2]. This has ensured not only that the CEN specifications are
robustly proved in practice, but also that they have the support of many key system developers and
operators.
With these Technical Specifications, it will be easier to achieve:
— more efficient development of PT components;
— lower cost, lower risks and a smoother on board integration of PT equipment;
— more efficient operation and maintenance of on board PT equipment;
— high quality intermodal passenger services based on intermodal PT information;
— integration of new PT services.
1 Scope
The CEN 13149 series of products concerns on-board data communication systems on public transport
vehicles. This series provides for data services that enable open and managed sharing of relevant
information.
This document, being Part 10 of the series, specifies a location publication, enabling all on-vehicle
services to share a common understanding of the location and orientation of the vehicle, based on
inputs taken from global navigational satellite systems (GNSS) such as GPS and Galileo. It covers:
— the functional scope, i.e. which data the service provides, why, when and how often;
— the transport protocol, i.e. how the data are transmitted;
— the service publication, i.e. how the service can be found by other modules or applications;
— the structure of the data, i.e. how the data are structured and how the data elements are named.
This document implements the service framework described in CEN/TS 13149-7.

4 Location Service
4.1 Functional Scope / Description & Use-Cases
The purpose of this service is to provide the geolocation data (i.e. basically coordinates) to other
applications in a vehicle network.
This geolocation data are issued by GNSS receiver as “raw” location information (even if this
information can be already pre-analysed by the receiver). Then such GNSS location data can be used
and correlated to any other available data to define a more accurate location information.
— The module hosting the Location Service shall have access to a suitable source of GNSS information,
for example through a GPS antenna.
Use cases include the following:
— A ticket machine may need location information to update fare stages.
— Location algorithms use the location data to calculate the position of the vehicle on the public
transport network.
— Fleet Management applications use the location data to monitor the vehicles position on
