Revised Figures
On Thursday 3 October 2024, travel time statistics for the local A roads were revised. The revision stems from a change in the provision of data following discussions with our suppliers and is to ensure consistency of the dataset moving forwards. See thetechnical notefor more information.
This adjustment results in minor changes to the figures, but it is important to note that these are minor and that revisions do not impact the overall trends observed.
Although all data previously published is valid, we recommend users who have previously downloaded or utilized the data to refer to the most recent dataset
