Introduction
[17]
An essential property of cooperative intelligent transport systems (C-ITS), see ISO TR 17465-1 , is
the sharing of data between different ITS applications providing different ITS services to the users.
This approach replaces the traditional approach where each application is operated in an isolated
environment, i.e. referred to as "silo - approach". The C-ITS approach enables synergies in components
of an ITS station unit, e.g. sharing of communication tools, improves overall performance and reliability,
and reduces overall cost. In order to protect the interests of the various ITS applications, C-ITS
implements the concept of an ITS station operated as a bounded secured managed domain.
The sharing of data between applications is achieved by subscribe/publish mechanisms, where at
least two mechanisms are distinguished, i.e. one allowing ITS-S application processes to subscribe to
standardized messages from ITS message sets (direct forwarding upon reception of such messages
in an ITS station unit), and one using a local dynamic map (LDM) as repository of standardized data
objects. Such data objects stored in an LDM are named LDM Data Objects (LDM-DOs). LDM-DOs provide
self-consistent information on real objects existing at a given geo-location during a given lifetime-
interval. Authorized ITS-S application processes may add LDM-DOs to an LDM, and may retrieve LDM-
DOs from an LDM. Retrieval of LDM-DOs may be performed in queries and by means of subscription. A
subscription will result in automatic notifications of selected LDM Data Objects either in defined time
intervals, or event driven.
This document introduces the usage of LDMs, and specifies the LDM for global usage in C-ITS.
[40] [42]
Initial implementations of LDMs were in the EU research projects CVIS and Safespot .

5.1 Local Dynamic Map
A Local Dynamic Map (LDM) is an entity consisting of LDM Data Objects, services and interfaces for
manipulating these LDM Data Objects (LDM-DO). LDM-DOs are distinguished by means of their LDM
Data object Type (LDM-DT). LDM-DTs are specified by registration in an LDM Data Dictionary (LDM-
DD). The concept of the LDM-DD is specified in Annex B.
[18]
NOTE In ISO TR 17424 , LDM-DOs are classified into Type 1 (static permanent data objects, e.g.
[2]
cartographic data), Type 2 (static transitory data objects, e.g. temporary parking lot on the road), Type 3
(dynamic transitory data objects, e.g. works location), and Type 4 (highly dynamic data objects, e.g. location,
orientation and speed of surrounding vehicles). This classification is not used in this document.
An LDM-DO provides information on real objects (cars, road events, .) that exist at a defined location,
e.g. in a defined geo-area, and within a defined time interval. In the uppermost simple case the
information provided by an LDM-DO is just its type, its geo-location, and its time interval of validity.
Such information may be received in an ITS station unit via different channels such as:
[34] [38]
— DATEX II , TPEG , RDS-TMC (legacy systems);
[19] [20] [28]
— CEN / ETSI / ISO / SAE ITS Message sets EN/ISO 19091 , ISO/TS 19321 , ETSI EN 302 637-2 ,
[29] [39]
ETSI EN 302 637-3 , SAE J2735 ;
composed of different sets of attributes, and presented in different formats (encodings). ITS-S
application processes capable to receive this information perform a mapping on LDM-DOs and a
translation of attribute formats into the common format given by the LDM-DTs.
5.2 LDM in an ITS-S
