the planned movement of a public transport vehicle on a DAY TYPE from the start point to the end point of a JOURNEY PATTERN on a specified ROUTE

NOTE In SIRI, the VEHICLE makes a call at each stop, for timetabled stops at a specific PASSING TIME. There may be a separate Arrival Time and Departure Time. A DATED VEHICLE JOURNEY is an instance of a VEHICLE JOURNEY made on a specific Calendar day.

a classification of JOURNEY PATTERNs used to distinguish other categories of JOURNEY PATTERN than SERVICE JOURNEY PATTERN and DEAD RUN PATTERN

a CONTROL ACTION consisting in assigning a new JOURNEY PATTERN (and the ROUTE supporting it) to a DATED VEHICLE JOURNEY

an oriented link between two ROUTE POINTs allowing the definition of a unique path through the network

a POINT against which the timing information necessary to build schedules may be recorded.

NOTE 1 to entry In SIRI, may be, but is not necessarily, a STOP POINT.

NOTE 2 to entry In many systems, Target Times for stops that are not timing points are interpolated simplistically from the timing points by either the scheduling system, or the AVMS system, and may represent a lower level of accuracy of prediction.

period in a day, significant for some aspect of public transport, e.g. similar traffic conditions or fare category

an indicator of traffic conditions or other factors which may affect vehicle run or wait times; it may be entered directly by the scheduler or defined by the use of TIME BANDs

parameters characterizing VEHICLE JOURNEYs or SPECIAL SERVICEs used for accounting purposes in particular in contracts between ORGANISATIONs

headway interval information that is available for a VEHICLE JOURNEY (to be understood as the delay between the previous and the next VEHICLE JOURNEY). This information shall be consistent with HEADWAY JOURNEY GROUP if available (HEADWAY JOURNEY GROUP being a more detailed way of describing headway services)

time allowance at the end of each journey on a specified JOURNEY PATTERN, to allow for delays and for other purposes; this layover supersedes any global layover and may be superseded by a specific VEHICLE JOURNEY LAYOVER

headway interval information that is available for all the VEHICLE JOURNEYs running on the JOURNEY PATTERN; this is a default value that can be superseded by the VEHICLE JOURNEY HEADWAY on a specific journey; this information shall be consistent with HEADWAY JOURNEY GROUP if available (HEADWAY JOURNEY GROUP being a more detailed way of describing headway services)

a time allowance at the end of a specified VEHICLE JOURNEY. This time supersedes any global layover or JOURNEY PATTERN LAYOVER

a part of a VEHICLE SERVICE composed of one or more BLOCKs and limited by periods spent at the GARAGE managing the vehicle in question

the time taken to traverse a TIMING LINK in a particular JOURNEY PATTERN, for a specified TIME DEMAND TYPE; if it exists, it will override the DEFAULT SERVICE JOURNEY RUN TIME and DEFAULT DEAD RUN RUN TIME

a TIMING POINT where a relief is possible, i.e. a driver may take on or hand over a vehicle; the vehicle may sometimes be left unattended

a classification for VEHICLE JOURNEYs to express some common properties of journeys for marketing and fare products

the sequence of a STOP within a JOURNEY PATTERN distinguishing repeated visits to a stop by a vehicle within the same journey pattern; a monotonically increasing number that is unique within a given journey pattern, but is not necessarily strictly sequential

NOTE The number provides both a unique identifier and a relative ordering.

an advertised destination of a specific JOURNEY PATTERN, usually displayed on a headsign or at other onboard locations

NOTE 1 to entry In SIRI, different values for DESTINATION DISPLAY may be used in the dated timetable, the real-time table, or on individual calls to support stop centric and vehicle centric presentations of information to the customer. If not specified on an individual Call element, the DESTINATION DISPLAY will be inherited from the most recent previous Call element. If there are no values on previous calls, it will be inherited from the DATED VEHICLE JOURNEY destination displays.

an allowed DIRECTION that can be used on a given ROUTE; this can be used to validate the selection of allowed values

an integer or a short alphanumeric sequence used to identify the LINE to the Public, for example: 11, 23, X3, 5A etc.

for Frequency based services, the interval between vehicles may be TIMETABLED, AIMED, ESTIMATED or ACTUAL

a classification of LINKs to express the different functional roles of a LINK

the physical (spatial) possibility for a passenger to change from one public transport vehicle to another to continue a trip; different transfer times may be necessary to cover interchange over a given connection link, depending on the kind of passenger.

In SIRI, a Feeder service may arrive at one STOP POINT in the CONNECTION LINK, and the Distributor may leave from the same or a different stop in the CONNECTION LINK.

The interchange duration, i.e. transfer time is the time needed to go from stop point to stop point across a CONNECTION LINK. In SIRI, it does not include time needed to board or alight. Several different types of interchange duration may be specified.

specialisation of LINE for flexible service; as all the service on a LINE may not all be flexible, flexibility itself is described at JOURNEY PATTERN level (meaning that a separate JOURNEY PATTERN is needed for each type of flexibility available for the line).

Types of flexible services are: Virtual line service; Flexible service with main route; Corridor service; Fixed stop area-wide flexible service; Free area-wide flexible service; Mixed types of flexible service; Mixed type of flexible and regular services

French standard (PR NF 99-506) for format describing public transport routes

NOTE This is especially useful for passenger information.

a part of a NETWORK comprising an edge between two nodes; not directional

a map representing schematically the layout of the topographic structure of the public transport network (a set of LINEs) and a set of SITEs; it can include a pixel projection of a set of ENTITies onto a bitmap image so as to support hyperlinked interactions

the time needed to go from stop point to stop point across a CONNECTION LINK

the order of a LINK in a LINK SEQUENCE to which it belongs

an ordered sequence either of POINTs or of LINKs, defining a path through the network

the role of the incoming VEHICLE to and VEHICLE JOURNEY at a TARGETED INTERCHANGE, which feeds passengers to an arrival STOP POINT having a CONNECTION LINK to a departure STOP POINT from where they will board a Distributor Service. A VEHICLE may perform both feeder and distributor roles at the same time, that is, both set down passengers to transfer to other services, and board passengers from other services.

the scheduled possibility for transfer of passengers between two SERVICE JOURNEYS at the same or different STOP POINTS

NOTE In order to reach the destination of a trip, a passenger will have to interchange between vehicles running on different LINEs, if there is no direct service between the origin and the destination STOP POINTS. A transfer will be necessary where the passenger will leave the vehicle at a particular STOP POINT and enter another vehicle (which serves another JOURNEY PATTERN, usually on a different LINE, at the same or another STOP POINT). Such interchanges may be planned and even sometimes guaranteed. They are therefore controlled during operations.

a suggested alternative solution for passengers when a facility/service is no longer available

a Transport Information System which provides travellers with optimized information to plan their door to door journeys and to support them during their intermodal trip

NOTE IJP systems provide timetable, routing and other travel information. An intermodal journey planner covers multiple modes of transport including both public transport (bus, rail, air, tram and underground) and private transport (car journeys, use of footpaths, cycle routes) on the road and path networks. Depending of the timetable of PT different stop points as start and end the PT TRIP may result.

word used to characterise the theoretical passage times of a vehicle at the different stop points along a route

the estimated deviation from the schedule for a VEHICLE JOURNEY, specified in seconds.

In SIRI, positive values are associated with vehicles that are behind their schedule, negative values with ones that are ahead.

a TRIP OPTIMIZATION QUERY represents the trip planning request, as specified by the traveller; it is expressed from one PLACE to another

the revised version of the TIMETABLE for a Service containing updates to the original published timetable.

NOTE The original TIMETABLED TIMES are referred to as TARGET TIMES.

an action resulting from a decision taken by the controller causing an amendment of the operation planned in the PRODUCTION PLAN

an EVENT may be raised in response to the disturbance and over the lifetime of the EVENT one of more CONTROLLER ACTIONS and messages may then be associated with it

NOTE In SIRI, the EVENT is generally avoided of more specific terms for entities. Any event affecting the public transport operation (production follow-up, management of information or the technical functioning), occurring on an OPERATING DAY and recorded in the system. An EVENT is generally causing a CONTROL ACTION.

NETWORK RESTRICTION specifying a POINT or a LINK where vehicles of specified VEHICLE TYPEs are or are not allowed to overtake each other

a CONTROL ACTION consisting in deleting a DATED VEHICLE JOURNEY from the latest valid plan

the concept of passing time may be viewed as a simple passage (e.g. of a bus at a stop point) or as a longer stay (e.g. in maritime ports of call)

NOTE The attributes describing the waiting time in the subtypes of passing time, in particular, will be used to describe such a call. The attribute ‘alight and reboard’ will express the possibility for the passenger to alight for a while, during the passing time of a vehicle journey at a particular stop poing.

The passing times that are computed on a specific operating day are called dated passing time.

This entity has several subtypes; TARGET PASSING TIME, the latest official plan for a dated vehicle journey, on a point in journey pattern; ESTIMATED PASSING TIME, a forecast for a monitored vehicle journey on a point in journy pattern; OBSERVED PASSING TIME, recorded for a monitored vehicle journey, on a particular point.

In SIRI Passing times are subsumed into a CALL entity.
