Local authority Bournemouth, Christchurch and Poole
1.16 billion vehicle miles were travelled on roads in Bournemouth, Christchurch and Poole in 2021.
Whilst historically significant, the long term trends can be misleading in most cases due to the extraordinary circumstances observed as a result of the coronavirus pandemic. Vehicle miles travelled in Great Britain have had year-on-year growth in each year between 2011 and 2019. Following a sharp decline in 2020, traffic levels for 2021 have increased on the previous year but still remain lower than the 2011 levels. Therefore, to say traffic has fallen over the last decade would misconstrue, as the overall decrease is entirely due to the decline in traffic levels observed in the 2020-2021 estimates.
Traffic estimates for the period since 2000 have been revised following the minor road review. Further details available on GOV.UK: Road traffic statistics: minor roads traffic estimate review
Traffic figures at the regional and national level are robust, and are reported as National Statistics. However, DfT’s traffic estimates for individual road links and small areas are less robust, as they are not always based on up-to-date counts made at these locations. Where other more up-to-date sources of traffic data are available (e.g. from local highways authorities), this may provide a more accurate estimate of traffic at these locations.
It is the responsibility of the user to decide which data are most appropriate for their purpose, and if DfT road link level traffic estimates are used, to make a note of the limitations in any published material.
Quality flags in data downloads
DfT’s road link level traffic estimates are calculated using a variety of methods, with some methods likely to produce more accurate estimates than others.
The data tables available to download here contain a column - estimation_method – showing the method used to estimate traffic for each location and year. Figures having an estimation method of “Counted” are likely to be more accurate than those marked as “Estimated”, and the latter should be used with caution.
