AAWT - Annual Average Weekday TrafficAAWT – Annual Average Weekday Traffic

 

Annual average weekday traffic (AAWT) is the total volume of vehicle traffic, weekdays only, on a road or motorway for a year divided by the number weekdays in the year. AAWT is a useful and simple measurement of how busy a road is during the working week. This calculations ignored any weekends or bank holiday.s The AAWT traffic data can be used for:

  • selecting a new site or business location
  • evaluating a site for development
  • determining funding for highway maintenance and improvement
  • forecasting road maintenance needs and expenditure
  • identifying the best location for your business based on traffic patterns
  • analysing the environmental hazards of pollution related to road transport

This is usually used by Highways departments of the local authority and Highways England, Scotland etc.

Similar surveys are AADT – Annual Average DailyTraffic which measures as above, but on all days of the year and ASDT – Average Summer Daily Traffic. This is a similar measure to the annual average daily traffic, however the ASDT data is collected during summer only. The measure is useful in areas where there are significant seasonal traffic volumes carried by a given road.
