## Appendix 1 Traffic Count Factors Introduction

The GMTU Traffic Counts System (COUNTS) incorporates factors which are applied 
to single day counts to produce estimates of annual average flows.  Three types of 
factor are involved.  These are: 
(i) 
Split-shift to 12-hour factors which are used to estimate single day 12-hour 
vehicle-specific flows from shorter period counts.  These factors are calculated from all available 12-hour continuous counts held on the COUNTS system; (ii) 
Factors to estimate average 12, 16, 18 and 24-hour flows from 12-hour 
counts. These are based on all available data from continuous Automatic 
Traffic Counting (ATC) sites throughout the county; (iii) 
Year to year factors. A new year to year factor is added each year and factors (i) and (ii) have been updated periodically as new data has become available.  This appendix presents factors that have been produced from 2007 (split shift) and 2008 (12-hour to longer period) data. These are applied to counts in 2009. Factors currently applied to earlier counts are available on request. 

Traffic Count Factors A. 
Split Shift to 12-Hour The factors and their associated standard deviations were derived from 12 hour manual classified counts undertaken at 32 motorway, 125 A road and 181 B, C or U road sites throughout the county during 2007. All sites were 2-way.

motor vehicle flows and the standard deviations of the estimates were derived from 
2008 Automatic Traffic Count (ATC) data at 27 two-way motorway and 55-two way 
non-motorway sites throughout the county. B.
