call

a visit by a VEHICLE to a specific STOP POINT as it follows the JOURNEY PATTERN of its VEHICLE JOURNEY to achieve a set of planned and estimated PASSING TIMEs
NOTE: A VEHICLE may make more than one Call to the same stop in the course of a JOURNEY: different calls may typically be distinguished by a Visit Number count. The Call may have real time data associated with it. A SIRI Call may be…

a visit by a VEHICLE to a specific STOP POINT as it follows the JOURNEY PATTERN of its VEHICLE JOURNEY to achieve a set of planned and estimated PASSING TIMEs
NOTE: A VEHICLE may make more than one Call to the same stop in the course of a JOURNEY: different calls may typically be distinguished by a Visit Number count. The Call may have real time data associated with it. A SIRI Call may be regarded as a useful optimisation of a more normalised set of structures that are articulated separately in TransModel. Call combines the TransModel elements of POINT IN JOURNEY PATTERN in with ESTIMATED PASSING TIME, OBSERVED PASSING TIME, & TARGET PASSING TIME, along with real time elements and other stop properties pertaining to the visit.
NOTE: That SIRI segregates all elements pertaining to arrival from those pertaining to departure, again facilitating the validation and implementation of actual systems.

call activity

the activity a passenger may undertake when a Vehicle calls at a stop; Boarding, Alighting, or Pass Through

centrally determined route guidance system (CDRG)

system which provides a driver with step-by-step driving instructions that are similar to those offered by a LDRG
NOTE: With a centrally determined system, the routing instructions are determined at an off-vehicle location and transmitted to the vehicle.

geocoding

software process of matching a street address or other geographic entity against a map database in order to derive the geographic co-ordinates of the address or the associated street segment determination of a link or node based on address information describing and/or naming a location

homing

also known as Tracing is the process that periodically updates the range and direction of the detected vehicle from an intercepting vehicle over a period of time; thus allowing entitled personnel to approach or intercept the detected vehicle without the necessary use of landmarks or absolute geographic references

term commonly associated with the standard for incident phrases developed by the SAE ITIS committee in conjunction with ITE TMDD and other standards
NOTE 1: : The ITIS documentation contains a wide variety of standard phrases to describe incidents and is expected to be used throughout the ITS industry. The codes found there can be used for sorting and classifying types of incident events, as well as creating uniform human readable phrases. In the capacity of classifying incident types, ITIS phrases are used in many areas. ITIS phrases can also be freely mixed with text and used to describe many incidents.

locally determined route guidance system (LDRG)

system which provides a driver with step-by-step driving instructions that are determined by an on-vehicle system
NOTE: The system typically consists of a display screen, a computer, routing and guidance software, a navigable map database, and positioning equipment to track the vehicle's location as it proceeds along its path.
