These tables have been revised to correct an error in percentage change in table CGN0401b.
On the Strategic Road Network (SRN) up to December 2019, the average delay is estimated to be 9.5 seconds per vehicle per mile compared to speed limits, a 0.9% increase compared to 2018.
The average speed is estimated to be:
- 58.8 mph
0.5% down on 2018.
In 2019, 67.3% 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 1.1 percentage points compared to 2018, so on average a slightly lower proportion of additional time is required.
On local ‘A’ roads up to December 2019:
- average delay is estimated to be 44.0 seconds per vehicle per mile compared to free flow
- average speed is estimated to be 25.3 mph
A break in the statistical time series for local ‘A’ roads travel times has been highlighted and therefore comparisons over a longer time period are not possible. The methodology note explains the cause and impact of this break.
Please note that figures for the SRN and local ‘A’ roads are not directly comparable.
