About this release
This release presents provisional estimates for road traffic in Great Britain for July 2022 to June 2023. Provisional estimates are published quarterly and remain provisional until after they have been constrained by the final annual estimates each year. These provisional estimates are based on traffic data collected continuously from a network of around 300 automatic traffic counters. Final annual figures also incorporate manual traffic count data.
Traffic shows a seasonal pattern at the national level, being highest in summer and lowest in winter. This publication focuses on rolling annual traffic totals, which better illustrate medium and long term trends in traffic.
Annual traffic estimates are usually published between May and June of the following year. The next provisional figures, for the year ending September 2023, are due to be released in December 2023.
Headline figures
Overall traffic levels in the year ending June 2023 were higher than in year ending June 2022 and below pre-pandemic levels.
Chart 1: Rolling annual vehicle miles travelled in Great Britain, from year ending June 2017 to year ending June 2023 (from TRA2501a)
Chart 1 is a line chart showing that 328.2 billion vehicle miles were driven on Great Britain’s roads in the 12 month period ending June 2023. This was up 2.3% compared to the year ending June 2022. Motor vehicle traffic levels fell during the pandemic but have since increased. This is the case for all vehicle types and road types. Traffic levels for the year ending June 2023 were 3.1% below pre-pandemic levels.
Road traffic by vehicle type
Chart 2: Share of traffic by vehicle type for the year ending June 2023 (from TRA2501a)
Chart 2 is a bar chart which shows that cars accounted for 75% of all motor vehicle traffic on Great Britain’s roads over the year ending June 2023. Therefore, cars continue to be the main contributor to changes in overall motor vehicle traffic.
The proportion of van traffic has increased in recent years, accounting for 18% of all motor vehicle traffic in this 12 month period.
Lorries accounted for 5% of all motor vehicle traffic and 2% of traffic came from other motor vehicles including motorcycles and buses.
In the year ending June 2023:
- car traffic was higher than the previous year and below pre-pandemic levels
- van traffic was higher than the previous year and above pre-pandemic levels
- lorry traffic was lower than the previous year and broadly similar to pre-pandemic levels
Table 1: Vehicle miles travelled in Great Britain by vehicle type in the year ending June 2023, and percentage change compared to previous 12 month periods” (from TRA2501a)
| Vehicle type | Year ending June 2023 | June 2022 (previous year) |
Dec 2019 (pre-pandemic) |
June 2018 (five years ago) |
|---|---|---|---|---|
| All motor vehicles | 328.2 billion |
2.3% | -3.1% | -1.4% |
| Cars and taxis | 247.0 billion |
2.2% | -6.1% | -4.2% |
| Vans | 59.1 billion |
3.8% | 10.5% | 12.2% |
| Lorries | 17.2 billion |
-1.9% | -0.1% | 0.1% |
Table 1 shows how traffic in the year ending June 2023 compares to a selection of earlier years for different vehicle types. For example, car and taxi traffic was 2.2% higher in the year ending June 2023 than the year ending June 2022. Note that any differences between -0.5% and +0.5% are considered negligible.
Cars and taxis
Chart 3: Rolling annual vehicle miles travelled by cars and taxis in Great Britain, from year ending June 2017 to year ending June 2023 (from TRA2501a)
Chart 3 is a line chart which illustrates that cars and taxis travelled 247.0 billion vehicle miles in the 12 months ending June 2023. Car and taxi traffic rose 2.2% from the year ending June 2022. Car and taxi miles for the year ending June 2023 were down by 6.1% compared to pre-pandemic levels.
Vans (Light Commercial Vehicles - LCVs)
Chart 4: Rolling annual vehicle miles travelled by vans in Great Britain, from year ending June 2017 to year ending June 2023 (from TRA2501a)
Chart 4 is a line chart which shows that 59.1 billion vehicle miles were driven by vans on Great Britain’s roads in the 12 month period ending June 2023. This was a rise of 3.8% compared to the year ending June 2022. Van distance travelled for the year ending June 2023 was 10.5% higher than pre-pandemic levels.
Lorries (Heavy Goods Vehicles - HGVs)
Chart 5: Rolling annual vehicle miles travelled by lorries in Great Britain, from year ending June 2017 to year ending June 2023 (from TRA2501a)
Chart 5 is a line chart showing that 17.2 billion vehicle miles were driven by lorries on Great Britain’s roads in the 12 month period ending June 2023. Lorry traffic decreased by 1.9% compared to the year ending June 2022. Distance covered by lorries for the year ending June 2023 was similar to pre-pandemic levels. The chart shows that the pandemic had a lesser effect on total lorry traffic than other vehicle types. Between the years ending December 2019 and December 2020, lorry traffic only fell by 5.9%, while car and van traffic fell by 24.9% and 9.2% respectively.
Road traffic by road type
Chart 6: Share of traffic by road type for the year ending June 2023 (from TRA2502a)
Chart 6 is a bar chart displaying that on Great Britain’s roads, in the year ending June 2023, 21% of motor vehicle miles travelled were on motorways, 44% on ‘A’ roads, and 35% on minor roads. 65% of motor vehicle miles travelled were on major roads (motorways and ‘A’ roads) despite comprising only 13% of the road network by length.
In the year ending June 2023:
- motorway traffic was higher than the previous year and below pre-pandemic levels
- ‘A’ road traffic was higher than the previous year and below pre-pandemic levels
- minor road traffic was higher than the previous year and below pre-pandemic levels
