Public transport - Road vehicle scheduling and control systems - Part 9: Time service

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 9 of the series, specifies a time publication, enabling all on-vehicle services to share a common understanding of current time, based on a suitable agreed master network clock. 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 FprCEN/TS 13149-7.

This Technical Specification (CEN/TS) was approved by CEN on 8 December 2019 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to

submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS

available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in

parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,

Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,

Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and

Introduction

This Technical Specification is Part 9 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 diffe
