Intelligent transport systems - ITS spatial data - Data exchange on changes in road attributes
This document defines the content specification for the exchange of road-related spatial data, and especially updates thereof. Based on the content specification, this document defines also a physical exchange format (structure and encoding) for the actual data exchange. In addition, it defines web services that are needed to make the coded data on updates available. Exchange of dynamic information is not in the scope of this document.
Although the focus of this document is on providing information on updates, the technology described in this document in principle also enables the exchange of full datasets, either concerning the whole road network in a coverage area, including all geometry and all attributes, or a subset, concerning for instance all instances of one or more specific attributes.
NOTE This specification does not support the provision of updates concerning geometry. The provision of geometry associated with attribution change is supported, in the context of providing the location of attribute change.

Introduction
ITS digital maps (digital maps for ITS applications) were initially developed for in-vehicle navigation
systems. Over time, these maps evolved, and their use extended beyond mere navigation, as a range of
other in-vehicle driving support systems were developed, many of which need ITS digital maps as an
important component for processing, interpreting and relating sensor data. This evolution from
navigation via ADAS (advanced driver assistance systems) and then C-ITS (cooperative ITS systems) to
automated driving generates increasing requirements for the digital map, in terms of content
specification, detail, accuracy and timeliness. The latter characteristic signifies whether the map data are
up to date with respect to changes in the real world.
ITS digital maps represent the physical road network infrastructure and its attributes, as well as other
relevant geographic information. The related data has a more or less permanent character, and is
sometimes referred to as static road data; road data that do not often change [9]. Besides for the
abovementioned applications, accurate and up to date digital maps have also high significance for the
provision of real-time road status and traffic information. This concerns dynamic road-related data, with
a highly volatile and temporary character. Typically data that will not be included in a digital map, but
generally need digital map data for processing, representation and display.
Although the road infrastructure has a rather permanent character, changes of the road network and
related attributes do actually occur at a significant scale. There is a need for timely and comprehensive
propagation of information on such changes to digital maps used in ITS applications. Providers of such
maps use a multitude of data sources to maintain their map databases, in order to keep these accurate
and up to date. These sources include visual inspection (by driving the roads), and the use of vehicle
probe data (big data that need processing, interpretation and verification).
The specification in this document aims to enable another mechanism for provision of static road data,
with a focus on changes, directly from the source of the changes: the public road authorities and/or
(public/private) road operators, who build and maintain the roads, and decide on and implement the
day-to-day changes that are relevant for inclusion in ITS digital maps. If road authorities and road
operators maintain a digital road database of their network, and have good procedures for keeping such
database fully up to date in a timely manner with respect to these changes, this would constitute a highly
efficient and potentially timely source for information on such changes for ITS map providers, but also
for other users of such data.
Based on good procedures, intense cooperation between the two sides of this data chain, and experience
gained over time, the data flow will achieve a high level of reliability, with known and guaranteed quality.
The data constitutes well-defined discrete data elements that do not need any big-data type of processing,
permitting swift implementation for any potential users. Dependent on the timeliness of the processes
deployed at, respectively, road authorities, road operators, ITS map providers and map-update-provision
services, the TN-ITS concept permits future transfer of information on road network changes to in-vehicle
systems with minimal delays. This document defines the TN-ITS specification.
The exchanged data elements are termed road features in this document. Each road feature is required
to have a location reference, identifying its location in the road network. The specification within this
document is flexible and supports the introduction of new data types by permitting the use of external
code lists.
The “Commission Delegated Regulation (EU) 2015/962 of 18 December 2014 supplementing
Directive 2010/40/EU of the European Parliament and of the Council with regard to the provision of EU-
wide real-time traffic information services” [9] sets out the requirements, for road authorities, road
operators and service providers, for the accessibility, exchange, re-use and provision of updates of static
road data, road status data and traffic data. Road authorities and road operators provide the static road
data they collect and update in a standardized format, if available, or in any other machine-readable
format, on a non-discriminatory basis, and digital map providers collaborate with the data providers to
ensure that any inaccuracies related to static road data are signalled without delay to the road authorities

SIST-TS CEN/TS 17268:2019
CEN/TS 17268:2018 (E)
and road operators from which the data originates. For dynamic road status data and traffic data the
Delegated Regulation in Articles 5 and 6 mandates the use of DATEX II (CEN/TS 16157 series and
subsequently upgraded versions) format or any machine-readable format fully compatible and
interoperable with DATEX II. The Delegated Regulation provides a list of types of static road data to be
addressed. This document takes full account of the part of the Regulation concerning static road data, and
supports and facilitates road authorities, road operators and digital map providers to implement and
fulfil the requirements of the Regulation with respect to the provision and use of such data.
The document’s specification is well aligned with Directive 2007/2/EU establishing an Infrastructure for
Spatial Information in the European Community (INSPIRE). Under this directive, public authorities
provide road network geospatial data sets in an INSPIRE-compliant way. Linear location referencing
enabled by this document’s specification establishes a direct (and INSPIRE-compliant) connection
between the exchanged road features and the originating geospatial data set of the public authority. This
will provide users with easy access to the specific location of the road feature in the originating database
for inspection, in case decoding of the dynamic location reference, used for automated processing of the
data, fails.
The idea for the TN-ITS concept for data exchange developed during the EU-funded projects
PReVENT/MAPS&ADAS (2004/2007) and SpeedAlert (2004/2005), and was further elaborated and
tested in the EU-funded ROSATTE project (Road Safety Attributes Exchange Infrastructure in Europe;
2008-2010), in which the basis for this specification was laid. This work led in 2013 to the foundation of
the TN-ITS Platform for deployment of the concept. In the past years, implementation in several European
countries took place, and a further roll-out in Europe with support from the EU CEF Programme
(Connecting Europe Facility) is ongoing.
The European Committee for Standardization (CEN) draws attention to the fact that it is claimed that
compliance with some stipulations of this document may involve the use of one or more patents when
using AGORA-C location referencing, standardized in ISO 17572-3, and/or OpenLR location referencing,
both described in 6.4 and Annex B. EN ISO 19148 for linear referencing has not identified any patents.
CEN takes no position concerning the evidence, validity and scope of these patent rights.
