I am trying to figure out the largest commodity for each highway. I was thinking I could find a way to graph it but I don't know if there is a way to connect each highway by city destinations and origins...
However, I can't find this data. Instead, I found data for commodities (by tons or value), origin (by city, state) , destination (by city, state) from this website: https://faf.ornl.gov/fafweb/Extraction2.aspx
I selected 2017 but I would rather have all years*
If you have a better data source for this, PLEASE share!!! I would highly appreciate it
which looks like this:
