I updated the DB based on the original submission here and subsequent confirmation from another member.

Besides ALERT 1 through ALERT 11 or 12 that are heard, who/what are the other callsigns that work with them? Like 864? I think there's other 700- and 800-series units, and what's an "Attenuator" unit?

I have information about the unit ID's for ADOT that is about 10-12 years old. I did not find 864 listed. The 800 number series contains both landscape and road maintenance units and I would imagine 864 is from a specific maintenance station that is responsible for the section of road involved in the incident you monitored.
The 700 ID series is for field offices, survey offices and labs. I wouldn't imagine that people from those field offices and the lab get into the field much. They probably use their cell phones for most of their communications.
The Phoenix Maintenance and Engineering districts actually have a 4 number series for ID's. I've never heard any of them use the "7" that is the first number in the 4. No one else has a number series ID as all the districts have the letter of the district as a precursor. Example, all the Globe units id as "G" plus a number that is based on what maintenance station they work out of and for the district office personnel as well. All the units of the Roosevelt Lake Maintenance Station ID as G52, G52-1 and so forth. G52 is the supervisor of the station and is the only person with a two digit ID. Units from the Superior Maintenance Station identify as G53, G53-1 and so forth. Units from the Flagstaff District ID with a "F" precursor and Kingman units with a "K" precursor.
The "7" is not really necessary and is redundant, so it is almost always dropped in actual practice. I really need to get some more current information to update what I have. I will try to remember to look up "864" and tell you what type of unit it is. I suspect that it is the supervisor of a maintenance station.
As for "Attenuator" I haven't a clue.

The attenuators are the trucks with the funny looking things on the back. They are generally raised for travel, then lowered when in use. The idea is that they 'attenuate' (or lessen) the impact of a crash. They serve to protect the people working in front of them. You rear end a truck doing 50 miles an hour you do major damage and someone is likely to get killed. You hit an attenuator and it's (more or less) like having an airbag, the damage is considerably less and you're more likely to survive and have less severe injuries.
Say for instance you're working on a guardrail and some idiot (or drunk) slams into your work area, it's going to be a disaster zone. You put an attenuator truck behind you, the drunk hits that truck which absorbs most of the energy. The truck may roll 15-20 feet, but the truck should be 50+ feet behind you, and everyone is safe.

I should have just used this Wiki link:

Exsmokey, from the SWFD-10 (circa 2009) 7700's - Phoenix District Construction; 7800's - Phoenix District Maintenance; 7830's Traffic Operations Center. So they drop the leading 7, and just use the rest of the ID, correct? That helps a little, thanks. I believe 864 was a specific vehicle type that was being driven by an ALERT member or maybe the supervisor from the radio traffic I was hearing.
Phoenix805, I know what you're talking about now. I never knew what they were called. I thought of them as bumper trucks, or crash protector trucks, or something along those lines.
Thanks to both of you.

Yes, the 7 is dropped. I've not known ADOT assigning a number to a piece of equipment. It is more likely that 864 (a person) was driving a specific type of vehicle.
I provided the SWFD with the ID information. I thought it said the 7 is dropped. My copy of the SWFD is at home and I'm a few hundred miles away right now. Maybe the directory I used to find the ID information is online and is more current. I'll take a look.

I programmed all four sites in Maricopa County for the YRCS and entered TGIDs for ADOT and DPS. I live near the 101 & 202 in Chandler and not too far from I10. I even drove on the south loop of the 202 today. I have received nothing from the four sites. Advice?
My YRC has been working fine. And here is a shocker I have better audio than the RWC..LOL I use White Tanks, South Mtn & Thompson Peek. Most of the traffic I hear comes off of South Mtn.

I have all 4 sites programmed in, and I have my PSR-500 set to check all CC's. The reason is, I have found that not all TG's are always carried on all 4 sites.
The Phoenix area DPS TG's (1001, 1002, 1003, 1017, 1018) are not linked full time to the UHF channels, so you will not hear them in use too often.
Even the ADOT TG's aren't in use 24/7. You may have just been listening during a quiet period.
I have recently picked up car-to-car chatter on 1108. I don't know exactly who it was, but I'm leaning towards ADOT workers.

Thanks ... That makes sense.

You will only hear the ADOT Yuma units on 1115 on White Tanks Mtn and the Pima unit on 1121 or 1122 on South Mtn. They are blocked from the other Phoenix Sites. Also there should be a lot of activity on tg 1109 which are the MVD units, they are checking vehicle regs all the time.

Peoria PD has a single vehicle rollover with an ejection and entrapment on Grand Ave at 71st Ave. They're landing Halo 151.
They also called for REACT, and REACT 2 came up on ALERT West to notify the TOC she was responding. So maybe REACT and ALERT both use ALERT's talkgroups.
Although, Grand Ave is a US highway and under ADOT's jurisdiction, so maybe that's why REACT is talking to the ADOT TOC.
It's 3:02am local, btw.
