Intelligent transport systems - Cooperative systems - Definition of a global concept for Local Dynamic Maps (ISO/TS 18750:2014)

The scope of the work is to create an environment and the standards to
implement a Local Dynamic Map (LDM) concept.
The current situation is characterized that applications directly exchanging their
information with the respective counterpart. Parallel applications exchanging their
information in the same way. Therefore, information used by multiple applications
has to be re-transmitted each time and creates a huge amount of data traffic. This
leads finally to the situation where communication channels become overloaded
and/or specific applications cannot be executed anymore due to the nonavailability
of connection resource.
The way out of this crucial situation is given if a common and coordinated local
data store concept is implemented.
This concept radically changes the way applications are developed and
implemented. If an application is requesting information, it is requested first from
the local data store, and only if the information is not available locally it is
requested and transferred from the external source via the air-link.
In this case, several provisions have to be given:
- The access to the data base has to be unified and standardized for all
applications
- The data elements and its attributes used have to be harmonized and
unambiguously defined
- Means to maintain the content and integrity of the data store, and means to
keep the content up to date have to be provided
- Means to apply local regulations for privacy and security have to be developed
- Last but not least the stakeholder-, user- and application-requirements have to
be derived and included in the development

Inteligentni transportni sistemi - Kooperativni sistem - Vzpostavitev globalnega koncepta lokalnih dinamičnih zemljevidov (ISO/TS 18750:2014)

Področje uporabe delaje ustvariti okolje in standarde za izvajanje koncepta lokalnih dinamičnih zemljevidov (LDM). Pri trenutnem položaju aplikacije neposredno izmenjujejo informacije z ustrezno nasprotno stranjo. Vzporedne aplikacije informacije izmenjujejo na enak način. Zato je treba informacije, ki jih uporablja več aplikacij, vsakič znova poslati, kar ustvari ogromno količino podatkovnega prometa. To končno vodi v položaj, v katerem komunikacijski kanali postanejo preobremenjeni in/ali določenih aplikacij ni več mogoče izvajati zaradi nerazpoložljivosti vira povezave. To ključno težavo je mogoče odpraviti, če se začne izvajati skupen in usklajen koncept shrambe lokalnih podatkov. Ta koncept bistveno spreminja način razvoja in izvajanja aplikacij. Če aplikacija zahteva informacije, se najprej zahtevajo od lokalne podatkovne shrambe, le v primeru, da informacije niso na voljo lokalno, pa se zahtevajo in prenesejo iz zunanjega vira prek zračne povezave. V tem primeru je treba zagotoviti več določb: – dostop do zbirke podatkov mora biti enoten in standardiziran za vse aplikacije, – podatkovni elementi in njegovi uporabljeni atributi morajo biti usklajeni in nedvoumno opredeljeni, – zagotoviti je treba sredstva za vzdrževanje vsebine in celovitosti podatkovne shrambe ter sredstva za posodabljanje vsebine, – pripraviti je treba sredstva za uporabo lokalnih predpisov za zasebnost in varnost, – nenazadnje je treba izpeljati in v razvoj vključiti zahteve na ravni deležnikov, uporabnikov ter aplikacij.

Introduction
[16]
An essential property of cooperative intelligent transport systems (C-ITS) 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 (ITS-S) operated as 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-DOs either in defined time intervals
or event driven.
This Technical Specification introduces the usage of LDMs and specifies the LDM for global usage in C-ITS.
[32] [34]
Initial implementations of LDMs were in the EU research projects CVIS and Safespot .

5.1 General
This Clause contains informative descriptions of the architectural environment of an LDM.
5.2 Local Dynamic Map
A Local Dynamic Map (LDM) is an entity consisting of LDM Data Objects (LDM-DO), services, and
interfaces for manipulating these LDM Data Objects. 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.
NOTE In Reference [17], LDM-DOs are classified into Type 1 (static permanent data objects, e.g. cartographic
[5] [5]
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 Technical Specification.
An LDM-DO provides information on real objects (cars, road events, etc.) that are existent 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
[30][26]
— DATEX II, TPEG, RDS-TMC (legacy systems), and
[22][21]
— CEN/ETSI/ISO/SAE ITS message sets,
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.
5.3 LDM in an ITS-S
The Local Dynamic Map (LDM) specification provided in this Technical Specification is designed for the
architectural environment of an ITS station operated as a Bounded Secured Managed Domain (BSMD)
specified in ISO 21217 and illustrated in Figure 1.
