Annual Average Daily Traffic (AADT) 2023

Annual average daily traffic (AADT) is the total volume of vehicle traffic on a highway or road for a year divided by 365 days. AADT is a useful and simple measurement of how busy a road is. The AADT traffic data can be used for:

• selecting a new site or facility location, evaluating a site, or designing a territory
• determining funding for highway maintenance and improvement
• forecasting road maintenance needs and expenditure
• identifying the best location for your business based on traffic patterns
• analyzing how traffic may impact store construction
• analyzing the environmental hazards of pollution related to road transport

The AADT Layer is a line layer that can be added to any Maptitude or TransCAD map. A size theme has already been added to the layer to help visualize the counts, but users can customize the layer any way they wish.

Available File Formats:

• Available for the latest version of Maptitude and TransCAD
• Available for other applications. Contact us to request the data in other GIS file formats (e.g., shapefile, KML, KMZ, GeoJSON).

Price: FREE For users of the current version of Maptitude or TransCAD

"I have a point layer of residences and a line layer of roads with traffic counts. I use the Overlay tool to calculate average traffic within 1,000 meters of each residence. All seems to work perfectly."
