How many roads in your state reach traffic thresholds

[thspfc]

How many roads in each state reach a given AADT at some point during their length?

In WI . . . https://wisdot.maps.arcgis.com/apps/webappviewer/index.html?id=2e12a4f051de4ea9bc865ec6393731f8

50k: 24. I-39, I-41, I-43, I-90, I-94, I-794, I-894, US-10, US-12, US-14, US-18, US-41, US-45, US-51, US-151, WI-11 (on I-39/90 concurrency), WI-29 (on US-51 concurrency), WI-32 (on I-41 concurrency), WI-35 (on I-94 concurrency), WI-164 (on I-94 concurrency), WI-172, WI-175, WI-190, WI-441

100k: 13. I-39, I-41, I-43, I-90, I-94, I-894, US-12, US-14, US-18, US-41, US-45, US-151, WI-164 (imposter)

150k: 6. I-41, I-43, I-94, I-894, US-41 and US-45 (concurrency merchants through the whole list)

If we take out routes that are carried by concurrencies, WI would have 18, 7, and 4 respectively.


The thresholds should vary based on the size of the state - i.e., counting all of California's 50k's would take forever, while Wyoming has no roads that reach 50k.

For Illinois, using data from 2019:

200,000 < AADT
6
(I-90, I-94, US-14, I-290, I-294, I-80)

100,000 < AADT < 200,000
7
(I-55, I-88, US-41, IL-53, I-57, I-190, I-355)

75,000 < AADT < 100,000
4
(I-64, US-12, IL-394, IL-159)

50,000 < AADT < 75,000
12
(I-39, I-74, IL-83, IL-59, IL-38, IL-50, IL-390, I-270, I-255, IL-64, IL-56, US-20)

Incidentally, the highest AADT on an unnumbered route is 91,900.

Incidentally, the highest AADT on an unnumbered route is 91,900.

Which route is that?

Which route is that?

I'll take a guess and say Western Avenue in Chicago.

It's a tie between Lawrence Avenue and Ohio Street.

That said, I'm not sure I believe Lawrence, or the bit about US-14 having an AADT above 200,000. It's possible that the data has errors or that I'm interpreting it incorrectly.
