abstract object classes typically have non-abstract specializations

taxonomic relationship between a more general element and a more specific element where the more specific element is fully consistent with the more general element and contains additional information

NOTE 1 to entry The more general class is referred to as the superclass.

NOTE 2 to entry The more specific class is referred to as the subclass.

NOTE 3 to entry “Fully consistent” means that the subclass has all of the properties and relationships of the superclass.

system comprised of information, communication, sensor and control technologies and that is designed to benefit a surface transport system

NOTE 1 to entry “Intelligent transportation system” is the American English equivalent.

NOTE 2 to entry Benefits potentially include, but are not limited to, increased safety, sustainability, efficiency and comfort.

NOTE 3 to entry The full term (i.e. “intelligent transport system”) is often used when the noun is used as a subject, whereas the abbreviation (i.e. “ITS”) is often used to modify another noun (e.g. “Intelligent transport systems provide ITS services.”).

ability of two or more pieces of equipment to operate in conjunction

physical object that has been assigned one or more functional objects in the provision of one or more ITS services

NOTE 1 to entry Physical objects are ITS components if they are an integral part of the system; otherwise they are terminators.

processes and/or procedures for ensuring continued business operations

Greek prefix denoting a description that is one level of abstraction above the concept being described

representation of an entity from which the important elements have been abstracted by removing unimportant detail while at the same time retaining the interrelationship between the key elements of the whole

NOTE 1 to entry A model may be made more or less abstract by the successive suppression of detail such that the concepts and relationships come into enhanced focus and become more readily understood. However the process can be taken too far when the simplification has exceeded the threshold where a necessary understanding may be achieved. Thus the process of modelling is one of going only far enough to achieve the optimum understanding and insight — and no further.

NOTE 2 to entry A model is a way of representing something, other than in its natural state.

ability to prove the occurrence of a claimed event or action and its originating entities

still valid, but is not to be used for new designs

NOTE 1 to entry This is a term that is used in the STATUS field of MIBs to indicate that the associated object no longer represents the preferred design, but the object may still be useful for backwards compatibility with legacy implementations. A deprecated object can be made obsolete with the next or subsequent release of

the standard.

state of being responsible, accountable or answerable, as for an entity, function, system, security service or obligation

ITS component that provides services in support of one or more other ITS components

EXAMPLE Data distribution system, network time source, cooperative ITS credentials management system.

a statement of what objective results are to be provided by the standard and how it is intended to achieve the vision

logistical framework for the agreement between a service provider and a user

NOTE 1 to entry The logistical framework can set restrictions on how a passenger and/or good is received, transported and/or delivered.

condition that must exist or be established before something can occur or be considered

measure of closeness of results of observations, computations, or estimates to the true values or the values accepted as being true

characteristic of a material entity that is equipped with enabled (i.e. on) and operational electronic communication technologies to support ITS services, including the means to send and receive data to and from other connected entities

NOTE 1 to entry The term “connected” does not imply support for any specific communications interface or ITS-S application process.

structure expressed in diagrams, text, and formal rules which relates the components of a conceptual entity to each other; particular set of beliefs, ideas referred to in order to describe a scenario or solve a problem

operational model where services are provided to a single user at any one time

EXAMPLE Traditional taxi service.

NOTE 1 to entry A single transport consumer can request the transport of multiple passengers.

adherence of a candidate's implementation to a standard

one or more similar or complementary ITS services provided to ITS users

ITS service actively requesting the data that is required for the service operation

legal framework for the agreement between a service provider and a user

NOTE 1 to entry Contracts can be via a third party, implied or verbal, especially in the case of peer-to-peer.

non-scheduled, non-fixed route public transport services for customers requiring special assistance and access to specific destinations at a user-requested time (e.g., disabled or elderly persons)

the exact equipment specification or manufacturers identification as installed in a deployment

state of an entity or a set of state variables; also the qualification of a contract or agreement

generalization class containing elements a class shares with other classes

set of rules defining the way in which data is put together with appropriate identifiers, delimiters, separator character(s), and other non-data characters to form messages

framework that may be used repeatedly to meet requirements that are similar to some extent

transport system designed to move material entities across the surface or near-surface of the Earth

NOTE 1 to entry A surface transport system can include tunnels, bridges and similar elements.

NOTE 2 to entry There is not complete agreement on the precise limitations of a “surface transport system” within the ITS community. Currently, the term is almost exclusively applied to ground-based travel of goods and people over significant distances. The term is viewed as including ferry systems, which often form an integral part of a local surface transport system; it is less clear if it includes long-distance sea-fairing ships. The term “surface transport systems” is also generally limited to transport systems that cover a considerable distance (e.g. factory conveyance technologies are not often referred to as “surface transport systems”). It has been suggested that air travel, which is arguably a transport system designed to move physical entities between points on the surface of the earth, ought to be included in the scope of the term, but this perspective is not universally accepted. It is expected that the exact limitations of the term will be further refined as ITS matures.

NOTE 3 to entry Due to the defined scope of ITS, the term “transport system” is intended to be interpreted as being synonymous with the term “surface transport system” unless explicitly specified otherwise.

use of wireless media to obtain and transmit (data) from a distant source

declaration made by an entity

NOTE 1 to entry Entity is a name, identity, key, group, privilege, capability.

a statement summarising the overall concept and goals that the standard seeks to achieve

smooth flowing and heavy traffic excluding stop and go and emergency braking situations

object class that represents a logical group of data elements and data frames that describe some aspect of the larger object class by which the nested object class is contained

NOTE 1 to entry Nested object classes are used to describe object classes that are contained within another object class and are used for conceptual objects rather than tangible objects.

EXAMPLE A message sign object class might have a nested object class for the messages stored in its library, where each message is described by a number of properties, such as message number, message content, message owner, etc.
