National Indicator for use on Principal roads in England.
BV224a has been renamed as NI169. This is the
National Indicator for use on non-Principal classified roads in
England.
The REVISED Weighting Sets are used to calculate
NI168 and NI169 in:
- 2009 using survey data collected during 2007/08 and 2008/09
The REVISED Weighting Sets were used to
calculate BV223 and BV224a in:
- 2008 using survey data collected during 2006/07 and
2007/08
The ORIGINAL Weighting Sets
were used to calculate BV223 and BV224a
in:
- 2007 using survey data collected during
2005/06 and 2006/07
- 2006 using survey data collected during 2004/05 and 2005/06
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.
Previous weighting sets can be found on this archive
