Annual Average Weekday Flow (AAWD)

The deseasonalised average traffic flow (two way) representing the typical volume of vehicles passing a count site between 0600 hours and 2200 hours on a weekday. This is roughly equivalent to AADT. Since the AAWD excludes those periods of the week more likely to be affected by 'unusual' events (eg short term roadworks, public gatherings, car boot sales), it is believed to provide a more reliable average when counts are conducted once or twice a year at a particular site.
