This dataset contains a consolidated view of Official Utilisation figures across all transport modes (train, metro, bus, ferry and light rail). Opal daily tap-on/tap-off data is aggregated to a total monthly figure representing the estimated number of trips across all transport modes.
Starting July 1, 2024, the methodology for calculating trip numbers for individual lines and operators will change to more accurately reflect the services our passengers use within the transport network. This new approach will apply to trains, metros, light rail, and ferries, and will soon be extended to buses. Aggregations between line, agency, and mode levels will no longer be valid, as a passenger may use multiple lines on a single trip. Trip numbers at the line, operator, or mode level should be used as reported, without further combinations.
The dataset includes reports based on both the new and old methodologies, with a transition to the new method taking place over the coming months. As a result of this change, caution should be exercised when analysing longer trends that utilise both datasets. More information on NRT ROAM can be accessed
