The average speed was 59.2mph. This is a 0.2% decrease on the year ending March 2016.

The reliability of travel times is measured using the Planning Time Index. This presents 68% of additional time needed compared to free flow, on average, on individual road sections to ensure on time arrival. This is a 2 percentage points increase on the previous quarter.
