The ORIGINAL Weighting Sets are used to calculate BV223 and BV224a in:
- 2006 using survey data collected during 2004/05 and 2005/06
- 2007 using survey data collected during 2005/06 and 2006/07
The REVISED Weighting Sets are used to calculate BV223 and BV224a in:
- 2008 using survey data collected during 2006/07 and 2007/08
To aid comparison between the Weighting Sets, the Original Weighting Sets can be used to calculate informal results using current data and the Revised Weighting Sets can be used to calculate informal results using older data.
Note that it is assumed that authorities have set up their Rural/Urban flag based on speed limit, with urban being used for all roads with a speed limit of 40mph or less. If you have used a different basis for your Rural/Urban definitions then please contact the UKPMS Support Contractor for guidance.
