Vehicular Traffic Volume in NCT

Big data pattern to know

  • 2024 and 2025 values are identical for every county in the file.
    So, in your dashboard, switching Year = 2024 vs 2025 will not change the Traffic Volume map/trend (unless you’re using a different dataset behind the scenes).
  • 2023 values are much higher and more spread out than 2024/2025.

2023 snapshot (highest volumes + lowest volumes)

Top 5 counties (highest Traffic Volume, 2023):

  1. Dallas County — 911.92
  2. Tarrant County — 613.37
  3. Denton County — 442.55
  4. Collin County — 416.68
  5. Rockwall County — 231.87

Bottom 5 counties (lowest Traffic Volume, 2023):

  1. Jack County — 22.20
  2. Palo Pinto County — 58.65
  3. Comanche County — 58.68
  4. Eastland County — 58.93
  5. Wise County — 64.41

What this means: In 2023, a few large metro counties (Dallas/Tarrant/Denton/Collin) dominate traffic activity, while smaller/rural counties sit far lower.

2024 snapshot (and 2025 is the same)

Top 5 counties (highest Traffic Volume, 2024/2025):

  1. Dallas County — 247.92
  2. Tarrant County — 156.29
  3. Collin County — 140.65
  4. Denton County — 118.66
  5. Rockwall County — 63.41

Bottom 5 counties (lowest Traffic Volume, 2024/2025):

  1. Jack County — 7.49
  2. Comanche County — 15.27
  3. Eastland County — 17.55
  4. Somervell County — 18.03
  5. Bosque County — 18.41

What this means: The ranking pattern stays similar (Dallas/Tarrant/Collin/Denton still highest), but the overall scale is much lower than 2023.

Trend insight (2023 → 2024/2025)

  • Every county shows a drop from 2023 to 2024 (in this file), roughly ~55% to ~77% lower, depending on the county.
  • The largest drops are in counties like Somervell, Tarrant, Stephens, Comanche, Hunt (around mid-70% decreases).
  • The smallest drop among counties is Erath (still a big decrease, ~55%).

Best way to phrase this on the dashboard:
“Traffic Volume shows a major shift between 2023 and 2024/2025 in the source data; 2024 and 2025 are identical in the current extract.”

Summary 

Traffic Volume compares how traffic activity varies across 24 North Central Texas counties over 2023–2025. The map highlights strong concentration in the region’s largest counties—Dallas and Tarrant consistently lead, followed by Collin and Denton, while smaller rural counties such as Jack and Comanche remain among the lowest. The data also shows a clear structural shift: 2023 values are much higher and more dispersed, while 2024 and 2025 match exactly in the current dataset, meaning year-to-year movement after 2023 is flat for this measure in the published extract.
