Highest & Lowest AADT by State and Route Type

[JayhawkCO]

This is where we need programming ability:

Code Select Expand

message = message.replace('~','[td]')
message = message.replace('@','[/td]')
message = message.replace('!','[url=https://tinyurl.com/')

Using ~, @, and ! to represent the longer text strings and putting this code at the end enables the entire table to be posted with slightly over 14K characters (the limit is 20K). Unfortunately, BBCode isn't Python.

Agreed.  It's a little over 500 characters for each state, so I can't get it there even with tinyurls.  (It says the maximum is 25K when it errors out for me.)  Oh well, I linked with big letters in the OP to the tables farther down the thread.  Hopefully people enjoy the GSV links.

They must have increased it.

Well, without bumping the other 8 year old threads, if any admin likes my thread and want to bump the character count to 35K, I'd be grateful.

Try removing https from the URLs. From what I understand with signatures, the character limit sees what you type in the text window, even if it gets formatted to go above the limit. You can also remove the closing [/url] tags safely, due to the way BBcode works. (This only brings you to 26.5K, but it's a start.)

I've spent plenty of time getting the data, getting the GSV links, and tinyurl-ing.  It'll just have to do for now.     If you think you can get me down to ~22K so that I can leave the Caveats on the OP, then maybe I'll take the time.

I managed to get it postable, though without much room for comments. 24401 characters + 292 because the black boxes count as two each = 24693.

* Remove the closing [/td] before the [/tr] – but only those, or else it will break.
* Remove all tabs. They aren't showing as empty space, anyway.

You can save about 300 by replacing the state names with their 2-letter postal code and about 200 by writing e.g. 115K instead of 115123 for 6-digit numbers. If you can manage to replace the black boxes with anything in the Basic Multilingual Plane, that will save 292 (this forum uses UTF-16 to determine character count).

OP edited.  GSV links added to all of the mileage markers.  Not much room for comments, but it'll have to do.

Adding the Streetview links is a nice touch. Looks like some of them aren't quite in the right location though.

For I-93 in NH you list the lowest volume at MM 118 but your streetview link is around MM 110. Here's MM 118: https://goo.gl/maps/z3vWe8iiqPWZjcNt9

For US 3 in NH the highest volume is on the Everett Turnpike, but your streetview link is to the Burque Hwy after US 3 exits the Turnpike. Here's the correct location: https://goo.gl/maps/78dfUGSean2AowBc6

You also mistakenly put the same URL for both highest and lowest on US 3 in NH.

Your links for the FEET and NH 16B are correct though!

I also looked into some of your MA data, and your highest volume location on US 3 is correct, however, it's just after the Lowell Connector splits off. Thus adding that volume to the Lowell Connector volume (25,973) yields an even higher total of 157,042 between MA 129 and the Lowell Connector. Unfortunately there's no counts from between those interchanges, but we can extrapolate.

Thank you.  I'll update this afternoon. 

Edit - Got a jumpstart.  All done.  I also adjusted the MM for MA-US3 since it looks like the AADT log was using old exit numbers instead of actual mileage or new exit numbers.  I defaulted to mileage.

Finally received the data from NMDOT so I could fill in the rest (and update the data with more recent (2017) stats).  All Google Street View links are added in the OP.

New Mexico
I-25 (Highest): Just north of I-40 interchange
I-25 (Lowest): In Socorro in between the northern exit for BL25 and before US60 merges

US70: Just east of I-25 in Las Cruces
US64: Just east of the end of US84 concurrency near Tierra Amarilla

NM423: The bridge across the Rio Grande in Albuquerque
NM1: Old US85 south of San Antonito

And this, then, makes NM the only state on your chart whose lowest SR AADT is on its SR-1.

It has an interesting history.  The road was NM1 (and much longer) but replaced by US85.  When they made US85 concurrent with I-25, they used the NM1 number again just for the segment between Truth or Conesquences and Socorro.  For a good chunk of that route, it's just a frontage road.  Also, when it branches off from I-25, it's not even signed from the interstate.  There are shields as soon as you get to the top of the ramp.

Having driven both stretches, I think the CA 60/I-215 multiplex is much more heavily traveled than CA 60 in Industry - and a contender for the world's busiest highway. Is there an AADT measured value for that part of Riverside?

[JayhawkCO]

Looks like new data is out for California. I'm going to ignore 2020 data, since that was obviously a weird year. But, according to 2019 data, the highest AADT in California is I-5 between 17th and Grand in Santa Ana, with an AADT of 504,000.

The highest AADT on I-215 anywhere is 253,000 between University and Pennsylvania in Riverside.

I'll update my chart for California at least tomorrow. If anyone else has states that they know have changed, let me know and I can update when I have time.

Edit: Here's the highest and lowest (still not reflected in the chart as that takes some work):

Interstates
Highest: I-5 in Santa Ana, 504,000
Lowest: I-5 north of Yreka, 7,500

US Highways
Highest: US101 in Los Angeles, 318,000
Lowest: US395 at Oregon Border, 760

State Highways
Highest: CA60 in Diamond Bar, 350,000
Lowest: CA299 at Nevada Border, 75

Yes Illinois is updated to 2021.
On the getting  around Illinois maps they did include 2020 to see how off it was. Though traffic is back here transit is not. It seems people will just drive and deal with traffic when its just 2 to 3 days a week in the office.
Thanks for this . It would be nice if there was a page to link to all the state traffic maps.

Link to the new traffic census data?  I'm interested to see where CA 62 east of Amboy Road to CA 177 is after driving it yesterday.

Interesting commonality between CA and WA: factoring the recent 2019 data in from JayhawkCO, I-5 is both highest and lowest for interstates, and US-101 is highest and US-395 is lowest for US routes.
