What this tracks
This dataset records traffic volume and vehicle type percentages on Tennessee roads, including daily traffic counts (AADT), truck traffic, and road classifications.
Why it matters to you
If you’re considering opening a business along Highway 64, the AADT field shows whether 1,700 or 17,000 cars pass daily — crucial for estimating customer traffic. Homebuyers can check VHCL_MU_TRK to avoid streets with 10% semi-truck traffic near their potential property. Tennessee drivers can use the K_FACTOR (peak hour congestion percentage) to identify roads that bottleneck during rush hour.
How to read this data
AADT — Annual Average Daily Traffic (sample: 1,698 vehicles) measures total cars/trucks passing a road segment daily.
VHCL_MU_TRK — Multi-unit truck percentage (sample: 1%) shows semi-trailer presence.
IS_URBAN — “Y” indicates urban zones where traffic patterns differ from rural roads.
RAW_DATA_LINK — Links to detailed traffic reports (sample: tdot.ms2soft.com/tcds).
