SIRIsample: A SIRI data frame sample

In SIRItoGTFS: Compare SIRI Datasets to GTFS Tables

Description

A data sample of preprocessed SIRI download, includes the data for the local public transport operator in Be'er Sheva, Israel for the date of 19/07/2017 All columns are intentionally character vectors, this is raw data to be used in the analysis process of STG. The table includes the maximum possible columns a SIRI protocol can produce( with the Israeli server, including wrapper nodes which produce NA columns), The data was collected for the development of the SIRItoGTFS package and contains only 100 calls to server, the "request_id" and "call_time_toServer" columns were added locally and are needed for anyone trying to use the package. the data is provided for anyone wishing to test the methods used during research.

Usage

SIRIsample

Format

A data frame with 2500 observations on the following 22 variables.

RecordedAtTime

Time stamp provided by the server, can differ within the same call, response rate for stops to server may vary

ItemIdentifier

The server's ID for each observation

MonitoringRef

The server's ID for the stop/group of stops

MonitoredVehicleJourney

A wrapper node, can be ignored

LineRef

The bus trip's route ID in the GTFS routes table

DirectionRef

The trip's direction code

PublishedLineName

The bus line's published name

OperatorRef

The operator's ID in the GTFS agency table

DestinationRef

The last stop's ID in the GTFS stops table

OriginAimedDepartureTime

The scheduled departure time for the trip

VehicleLocation

A wrapper node, can be ignored

VehicleRef

A unique vehicle ID

MonitoredCall

A wrapper node, can be ignored

Longitude

The observations recorded Longitude on a WGS 84 projection

Latitude

The observations recorded Latitude on a WGS 84 projection

StopPointRef

The stops' ID in the GTFS stops table

VehicleAtStop

Is the vehicle currently at the stop, by default NA which is FALSE

ExpectedArrivalTime

The predicted time the bus will arrive at the stop

request_id

A unique identifier for each call to server

call_time_toServer

Local time stamp for each call, not for each response

AimedArrivalTime

The scheduled time, only relevant for trips that have not yet begun

ArrivalStatus

In fully operational systems this should report whether the bus is early or late, in this case it does not report anything
