GB Road Traffic Counts
Posted by Department for Transport on 08/02/2012 7 comments
Data are available for Annual Average Daily Flows (AADFs) for count points on major roads (motorways and A roads) and minor roads (B, C and unclassified roads). Traffic figures for major roads are also available (in vehicle kilometres and vehicle miles).
AADF figures are produced for each junction to junction link on the major road network for every year.
Only a sample of points on the minor road network is counted each year and these counts are used to produce estimates of traffic growth on minor roads.
A description of how annual road traffic estimates are produced is available at http://assets.dft.gov.uk/statistics/releases/traffic-estimates-2010/traffic-estimates-2010-methodology.pdf.

Raw counts
241 MEG!! Can you please zip it down to a reasonable size or split it up by LA?
Zipped files
I've passed your comment back to the team that owns these datafiles and asked them to replace the originals with zips rather than CSV files.

Where's the AADF data?
The Annual Average Daily Flow (AADF), traffic count point data is not available for download from the suggested DfT matrix.
This supposed dataset is also linked to from CKAN (http://ckan.net/package/dft-road-traffic-counts). There's a rather archaic looking 'interactive' web map thing.
The data does not seem to be either openly licensed or available from any obvious place, who would a request be?

Where is the data ?
It seems that the data disappeared, and it's not easy to be found at the linked website. I was able to find only aggregate figures, and not in RDF. Also, applications depending on these data seem to be off. Any explanation on why this data is not anymore here ? Any hint on where to find it ?
Where is the data?
Hello,
It looks like the data has been archived but is still available via the National Archives website - if you follow the above link you will see an onward link to: http://webarchive.nationalarchives.gov.uk/+/http://www.dft.gov.uk/pgr/st... - the data is available in the right hand side column.
The road injuries application still appears to be up and running but I note that the GB roads visualisation app no longer appears to be available, we will look into this and update/remove as appropriate.
Many thanks,
Phil
Where is the data ?
Hi,
I had a look. But it seems there are only aggregate information available on the website. From blogs/apps I have seen around, I had got the idea that there was more detailed information in the endpoint, like values for specific countPoints. Am I wrong ?
Updated links
I have updated the links to point at the 2008 and 2009 aggregated statistics plus the Matrix site which allows users to get annual average daily flow figures for each the major (motorway and A road) count points.
When (and if!) I can figure out where the RDF is hosted (DfT doesn't host this themselves, the Cabinet Office / National Archives does as part of data.gov.uk) I will add a link to that as well.
