The data presented shows the percentage of ‘journeys’ that are ‘on time’ by road section by rolling year. This data can be used to track the percentage of ‘journeys that are ‘on time’ for individual road sections (or ‘links’) over time where source comparability issues are not highlighted. The data for individual road sections should not be ranked (e.g. to define a “best” or “worst” link) or compared with others.
