Data quality indicator

The data quality indicator displays the volume of actual journey level real-time data (GTFS-RT) that has been received and compared against the schedule data (GTFS Schedule dataset).


The data quality indicator is found in the top right of the KPI Dashboard (1).

Matched = at least one instance of real-time data (a heartbeat from a vehicle) has been matched against a journey from the GTFS Schedule dataset.
No data = no instances of heartbeats (real-time data) have been received to match a scheduled journey in the GTFS

Cancelled = A trip that existed in the schedule but was removed

The view can be toggled to display a journey percentage or a count as preferred, and changes to reflect whether all operators or one operator is selected (2).

A journey will be considered “matched” if one real-time heartbeat can be matched to a journey from the GTFS Schedule dataset.

Real-time heartbeats received without a trip_ID are classed as dead running and don’t register in this data.

EXAMPLE #1

By toggling between the percent and count figures, we can see that over 270,000 journeys have been matched from the real-time data to the schedule data, which equates to 96% data accuracy.
