tachograph
sender unit mounted to a vehicle gearbox, a tachograph head and a digital driver card, which records the regulated vehicle speed and the times at which it was driven and aspects of the driver’s activity selected from a choice of modes
classified information
information which for reasons of national security is restricted to government authorized or approved persons
secret key
key that is used with a symmetric cryptographic algorithm
NOTE 1 Possession of a secret key is restricted (usually to two entities).
NOTE 2 For ERI, there can be only one entity or several entities, depending on the key management policy.
tarrification
calculation of the tariff
tariff zone – IFOPT
ZONE used to define a zonal fare structure in a zone-counting or zone-matrix system
tariff scheme
set of rules to determine the toll due for a vehicle in a toll domain for a tolled object at a certain day and time
EXAMPLE A table that shows the toll for various classes of vehicle.
truck-tractor
heavy single-chassis vehicle providing propulsion, control, and crew (driver) accommodation, with the primary purpose of controlling and transporting one or more separate load-carrying trailers
technical architecture
the concept of the technical delivery platform in terms of technical components, their interfaces and interactions
technical model
tModel of UDDI describes a "technical model" representing a reusable concept, such as a Web service type, a protocol used by web services, or a category system
facility – SIRI
equipment or service that provides a specific convenience or service to passengers
EXAMPLE Ticket machines, elevators, mechanical stairs, toilets, porterage, left luggage, etc.
NOTE A facility may be an equipment, a service, a personal device or a reserved area.
object modelling technique
is an object-oriented development methodology, which can be applied to the formulation of an architecture
access technology
technology employed in a communication interface to access a specific medium
ITS-S access technology
access technology dedicated to operation in an ITS-S
PSAP emergency telephone number
telephone number, generally conformant with the E164 general numbering scheme, which a TPSP can dial internationally in order to establish a voice connection to the PSAP as part of a TPS-eCall notification
VehiclePhoneNumber
telephone number of the TPS In-Vehicle System which may be used to attempt a call back to the vehicle
telecom operator
provider of telecommunications services not dedicated exclusively for an ATSVR System, but used in many application areas (e.g. Network Operator of a GSM, RDS, communication satellite, optical cable, PSTN network)
telematics
use of wireless media to obtain and transmit (data) from a distant source
Teleservice
teleservices supported by a PLMN that supports Teleservice 12 are described by a number of attributes which are intended to be largely independent
NOTE They are grouped into three categories: - High layer attributes. - Low layer attributes (describing the Bearer capabilities which support the Teleservice). - Information transfer attributes. - Access attributes. - General attributes; examples include including fax-on-demand, voice mail computer telephone integration and emergency services support; in the case of GSM/UMTS circuit switched networks circuit switched networks.
topic – WS-PubSub
a concept used by a Notification Producer to categorise Notification Messages to decide which Subscribers should be sent a Notification
NOTE 1 to entry A Subscriber specifies which Topics it is interested in as part of its Subscription Request.
field test
test that is performed under real-life conditions
Terminal
provides the user interfaces with the TMC service
NOTE 1 to entry: Their functionality may cover a range of terminal functions from simple terminals with a limited message repertoire and restricted location database to more sophisticated terminals offering full TMC message features and/or a wide range of strategic and tactical location databases.
terminator
entity that is external to the system but with which the system communicates either to obtain inputs or to which it can send outputs
NOTE 1 Terminators may be split up into actors if necessary.
NOTE 2 In most ITS architectures, the terminators may be the same in both the functional and the physical viewpoints.
NOTE 3 In the US National ITS Architecture, a terminator defines the boundary of the system of interest. Each terminator may represent the people, systems and general environment that interface to ITS. The interfaces between terminators and the sub-systems and processes within the National ITS Architecture are defined, but no functional requirements are allocated to terminators. The logical and physical architecture views of the National ITS Architecture both have exactly the same set of terminators.
TETRAPOL
the name of a fully digital radio communication standard for professional communications organisations; it is based on an FDMA (frequency division multiple access) multiplex approach using a narrowband channel operating at 12,5 kHz channel spacing
Silent Cancellation Message
used to delete messages from the end-user terminal
silently drop
to ignore a data packet
NOTE A data packet that is silently dropped does not cause any action to occur within the receiving system, nor is any response sent to the subject data packet.
TOPO
name of an ITS message set used to carry information on digital maps covering the area of intersections
topographical place – IFOPT
geographical settlement which provides topographical context when searching for or presenting travel information, for example as the origin or destination of a trip
NOTE 1 to entry: It may be of any size (e.g. County, City, Town, Village) and of different specificity, e.g. Greater London, London, West End, Westminster, St James’s.
NOTE 2 to entry: A TOPOGRAPHICAL PLACE may be associated with a PLACE (including a STOP PLACE), but not all PLACEs are TOPOGRAPHICAL PLACEs. TOPOGRAPHICAL PLACEs may be organised through hierarchical containment and disjoint adjacency relationships.
NOTE 3 to entry: A TOPOGRAPHICAL PLACE should always have a canonical gazetteer name. It may be necessary to use the hierarchical topographical relationships of the TOPOGRAPHICAL PLACE to establish a unique context with which to distinguish between two TOPOGRAPHICAL PLACEs with the same name.
shape point
position along a link used to more accurately represent its geometric course, bounded by exactly two segments
