Dear Hasintha Nawod Kalpana ,

There are numerous open data hubs where you can access AADT data. One is ArcGIS Hub, where you can download AADT data provided by various institutions, including transportation agencies, municipalities, and universities.

As an example, I've written a sample search query for you:

https://hub.arcgis.com/search?collection=Dataset&q=annual%20average%20daily%20traffic

This link will take you directly to a collection of AADT datasets available on ArcGIS Hub. I hope it helps.

You can find "Average Annual Daily Traffic Volume" or "Daily Traffic Volume" data from government transportation agencies, open data portals, academic institutions, and commercial data providers. Specific sources may vary by location.

1. State or Provincial Transportation Departments:

2. Federal Transportation Agencies:

3. open data portals

4. commercial data provider

5. Academic and Research Institutions:

In the UK, go to WEBtris online. National Highways provides free data via their Webtris interface.
