Details
On the Strategic Road Network (SRN) up to June 2019, the average delay is estimated to be 9.4 seconds per vehicle per mile compared to speed limits, a 1.2% increase compared to the year up to June 2018.
The average speed is estimated to be 59.0 mph, 0.4% down on the year ending June 2018.
In the year to June 2019, 66.8% of additional time was needed compared to speed limits, on average, on individual road sections of the SRN to ensure on-time arrival. This is down 2.1 percentage points compared to the year ending June 2018, so on average a slightly lower proportion of additional time is required.
Please note a break in the statistical time series for local ‘A’ roads travel times has been highlighted and therefore comparisons over time are not possible. A methodology note (PDF, 316KB) explains the cause and impact of this break.
On local ‘A’ roads up to June 2019:
- average delay is estimated to be 43.2 seconds per vehicle per mile compared to free flow
- average speed is estimated to be 25.4 mph
Please note that figures for the SRN and for local ‘A’ roads are not directly comparable.
