PTV Timetable API Data Quality Statement
A Data Quality Statement is recommended under the DataVic Access Policy Guidelines as an effective mechanism for communicating information about the quality of the data and how they can be used.
This Data Quality Statement applies to both Version 2 and Version 3 of the PTV Timetable API.
Data source
PTV Timetable API
Institutional environment
Data collector(s)
Data are created and collected by or on behalf of Victorian public transport train, tram and bus operators and by Public Transport Victoria.
Collection authority
Public Transport Victoria
Data compiler(s)
Public Transport Victoria (a government agency) compiles the data.
Additional information
Timetable data change frequently (for example, over summer, or for planned works) and are updated on an as-needs basis. Changes are advertised on the PTV website. As the data are accessed through an API, the data released are always up-to-date.
Relevance
Data topic
The data collected are the public transport timetable (and associated data) for services in the state of Victoria (including Melbourne metropolitan services).
Level of geography
The state of Victoria.
Key data items
Timetable, station/stop locations, line/route paths, disruption information, stop-facility data for metropolitan train and V/Line train stations, real time data for train, tram and bus services where these are made available to PTV, and myki ticket outlets.
Additional information
The PTV Timetable API does not provide access to the PTV Journey planner nor the HERE Geocoder API (used by PTV to search addresses).
Timeliness
Data collected
The data are collected and compiled for release on an as-needs basis (this does not include real-time data which is a service on demand).
Data available
The data are made accessible through the PTV Timetable API. Their availability is current.
Referenced period
Approximately 14 days.
Additional information
Public transport scheduled timetable, real time, stop/station, route and line data change frequently. To ensure you access the most up-to-date data, it is strongly recommended you use the API dynamically.
Accuracy
Method of collection
The data are collected both manually and through electronic file.
Data adjustments
The data contain interpolated times for stops on bus routes that are not timing points.
Collection size
All public transport services in the State of Victoria.
Additional information
The data released are consistent with the data released by PTV through its apps.
Coherence
Consistency over time
The data are consistent over time in that the same set of data (i.e. pertaining to services provided by public transport operators) are consistently collected and released.
Consistency of jurisdictions
Unknown.
Time series
There is not a consistent time series for this data. Timetable data change frequently. PTV only keeps the current timetable data (not including real time data which is a service on demand). PTV does not archive the old data once they have changed.
Interpretability
Context
The PTV Timetable API gives the public access to raw public transport timetable data. It is not a Journey planner service.
Accessibility
Additional information
PTV has also released other public transport data through the DataVic website.
