for anyone who want to use this mod, i use this mod after the update of 1.53, and it works just fine no crashes.
only strange thing indeed is, the AI seems to like to drive on the fast lane the whole time lol.

Update please. seems it doesn't work for me i still have a hard time overtaking cars and trucks because the distance between two cars is still close.

I just tried this mod for half an hour or so, it's seems to work pretty fine but there something strange. On the highway, I'm driving on the rightest lane and all the cars and trucks that I encounter on the same side of the road are driving on the left lane. So I overtake them by the right and not the left... That's not very realistic..

ItsSolor-24 29 Jul, 2022 @ 11:21am

ETS2 uses the same file and I even have the same mod available for ETS2, but both use the same data. Only the safety and patience parameters were changed regardless, so it shouldn't have an effect on changing lanes.
carfreak554 30 Jan, 2022 @ 4:23pm 
alright, idk ive just noticed this, but ive only noticed it on ATS, ETS2 they change lanes fine, maybe you can change the file from ETS2 over to ATS with some edits, idk how complex it is, or if you made the ETS2 version of this mod
TheKnoife  [author] 30 Jan, 2022 @ 4:09pm 
I actually reinstalled ATS a while ago so I had a look at the file but nothing was changed since late 2019 (mod upload). If the AI are unable to changes lanes I'm not sure what is causing that.
carfreak554 30 Jan, 2022 @ 2:05pm 
hi so I have noticed that this mod seems to give the AI an inability to change lanes? judging by your last messages you don't mod anymore with ATS/ETS2 but if you could fix that it would be nice, thanks!

I got tired of replacing brush bars weekly for my trucks too...thanks for this mod!
AlconburyBlues 1 May, 2021 @ 6:14pm 
Understood, over and out.
TheKnoife  [author] 1 May, 2021 @ 10:21am 
I do some light speedrunning for fun actually, never really online. As for the mod, just pretend it's already called the 70s mod so I don't have to upload another one haha
AlconburyBlues 28 Apr, 2021 @ 3:41pm 
That's cool I downloaded rocket League a long time ago but never got a chance to play it more than 15 minutes. And GTA I left a year ago after achieving level 550 on my main character and almost 250 on my second. But I'll never leave GTA completely let me know if you want to add me in there so we can hook up.

As far as the mod on topic I already suggested make the current version and just rename it like '70s style driving or something like that
TheKnoife  [author] 28 Apr, 2021 @ 3:04pm 
Basically rocket league and GTA.

But if you really want an extra version of the mod just say it and I'll cook something up
AlconburyBlues 21 Apr, 2021 @ 4:47pm 
No you did great work. It's sad to see you go. What game is occupying your time now?
TheKnoife  [author] 21 Apr, 2021 @ 10:12am 
I found the file, the current limit of the total AI is set to 50 (stock is 50 as well, but I think the changes in the mod greatly change flow which may explain the lower amount of vehicles on screen).
I don't have the interest to set up a change in the mod name but I'm willing to put up a version of this exact mod with a bit more traffic while slightly lowering the safety settings.
Right now these are the other settings:

ai_safety_modifier: 1.0 (stock is 0.3)
ai_patience_modifier: -1.0 (stock is 0)
ai_horn_delay: (7.0, 15.0) (stock is 4.0, 8.0)
ai_blink_delay: (1.0, 4.0) (stock is 3.0, 6.0)
ai_yield_wait_time: (10.0, 20.0) (stock is 20.0, 30.0) lower patience -> higher wait time
ai_yield_timeout: (2.0, 5.0) (stock is 3.0, 5.0) lower patience -> lower timeout

let me know what you think is best
AlconburyBlues 21 Apr, 2021 @ 3:34am 
Sounds good. But as I said, I would keep this version as a "70s" version. I actually backed up a copy of it for myself for this reason. I like driving the slower trucks with slower sparse traffic sometimes.

But for the life of me I can't find that mod (albeit when I was using it, it was 2017) that changes all the scenery and signage to make it look like 1970. If you know what mod I'm talking about, help me out here. I can't find it anymore and apparently lost the only copy I had.
TheKnoife  [author] 20 Apr, 2021 @ 6:33am 
Hi, thanks for the message. I actually don't play the game anymore but I'll have a dive into the code to see if I can increase the amount of traffic in the same file.
AlconburyBlues 20 Apr, 2021 @ 2:40am 
.....part 2:

Overall: The traffic indeed drives safely. But I think "over-the-top" safely and slow for a modern day feel.

The upside: One advantage to this traffic mod in it's current state . And I do mean keeping the issues I am mentioning here. If anyone still plays with the 1970's mod and 60's/70's trucks to make it look and feel like it did 50 years ago, this AI traffic mod would be perfect for that. Because that's exactly how people drove back then. (I grew up in that era.) It literally felt like 1970, with much less traffic, and everybody giving more room and driving slower.

I would definitely keep this mod. But I would rename it "1970's Traffic Behavior" because that's exactly what it is. I would keep it in my favorites for that reason.
AlconburyBlues 20 Apr, 2021 @ 2:39am 
Hi Knoife,

This mod seems to be going in the right direction, but needs some tweaking. Very good job, but 2 things I noticed need improvement if you are trying to replicate 2020's traffic behavior. (Note on that below.)

1) The traffic seems to be half as much as default. Great for framerates and low end PCs, but seems dull with the only major traffic being in cities and towns.

2) After trying this mod for about 6 hours, I noticed that most of the time the traffic drives at the truck speed limit instead of going faster. Not only was it strange seeing all the cars go as slow as trucks, but it made it very difficult to change lanes. Because now you would have some car matching your speed right next to you, and you no longer have the ability to wait for him to move on so you can get behind him.

mettre a jour plz
ARJEEL 26 Jan, 2021 @ 12:05pm 
I tried a couple AI traffic mods and am happy to not have maniacal suicidal torpedos for traffic anymore with this mod. Great! I think the density is good, and their movements much smoother.
Bandit Gambino 25 Dec, 2020 @ 1:31pm 
Funny, every time they over take me they go into right lane and hit the brakes.
Wolfpack_366 18 Dec, 2020 @ 3:30pm 
Tbh I am just gonna stay away from Idaho seems to keep crashing my game
TheKnoife  [author] 18 Dec, 2020 @ 3:18pm 
Try a fresh save, and only my mod. Let me know if it still crashes (on specific things)
Wolfpack_366 18 Dec, 2020 @ 2:53pm 
ok I am just runnin through all the mods because I keep crashing love your mod
TheKnoife  [author] 18 Dec, 2020 @ 1:42pm 
Should work fine, if there's any issues I'll update the mod
Wolfpack_366 18 Dec, 2020 @ 12:10pm 
Is this completely updated for 1.39
TheKnoife  [author] 17 Oct, 2020 @ 9:19am 
Should work fine, if there's any issues I'll update the mod
AURORICSTΛR ☆ 15 Oct, 2020 @ 11:00am 
Does this work with 1.38 and 1.39 beta?
Mark Reynolds 21 Jul, 2020 @ 2:40pm 
@SmokerBait, very realistic behaviour, happens all the time in real trucks, truck drivers these days are as bad as everyone else, proper rat race behaviour :D
Smokerbait 9 Jun, 2020 @ 11:10am 
Not a bad mod, but it will create some interesting AI behavior which may, or may not, bother you.

ALL the AI vehicles drive faster, which is good in that you don't get stuck behind slow traffic, but cause them to behave unrealistically. I had a bus drive in the left lane for an hour (in-game) as it slowly, slowly, slowly passed me.

The speed can be 60, you're doing 62, and every other truck is passing you in the left lane doing 70.

You won't be able to pass anyone. I came across a truck entering the highway which was uphill, so it started off going rather slow. I had enough momentum to pass, but by the time we crested the hill, he began accelerating. Speed was 60, I'm doing 65 just trying to complete the pass (trying not to get a ticket), and he's now beginning to pass me in the right lane.

Again, it's not necessarily terrible. Some people will appreciate it, some won't.
TheKnoife  [author] 27 Dec, 2019 @ 9:57am 
That kind of AI behavior isn't set in the files I'm editing. AI will yield better with my mod though, but you just need to pull out enough for them to stop. Otherwise reload your game to delete traffic.
trainguy_modding 26 Dec, 2019 @ 4:53pm 
@mazdarati2, in the next version can you make the cars stop when you're pulling out of something?
h6833ist 12 Dec, 2019 @ 12:18pm 
Makes for a nice drive. Very good.
GT182 6 Dec, 2019 @ 7:53am 
And the left lane hogs need to be fixed..... trucks and cars. Especially the slow ones.
TheKnoife  [author] 1 Dec, 2019 @ 5:01am 
Yeah, browse my workshop files.
g00fball 30 Nov, 2019 @ 4:46am 
do you have an ETS version of this for 1.36
Remi麦岱 19 Nov, 2019 @ 10:06pm 
Thanks! I hate when an AI just decides to get in front of you and the limit goes from 45 to 65 but they have to stop and make sure they can go 65 I guess... Rear ended someone at like 70 because of that lmao
Overspark 19 Nov, 2019 @ 12:42pm 
Heh, good question. Main annoyance this mod fixes for me is cars cutting right in front of you and then stepping on the brakes, so I guess we need to err more on the safe side to keep that properly fixed... :lunar2019grinningpig:
TheKnoife  [author] 18 Nov, 2019 @ 4:06am 
@Overspark I think that is due to the safety parameter, because it's really high. The safety modifier controls this (I quote the SCS file): Vehicles with low safety factor tend to brake more abruptly, use low spacing distances, use lights later in case of low visibility...

In short = more safety means more distance. Not sure what I can do, but I might do a temporary edit to the parameter to see if it improves at all. Let me know what value you want to see (default is 0, modded is -1)

@kostial.k unfortunately the amount of traffic is controlled by the same file I used for modding the traffic behavior. Adding a bit more traffic may be possible if it isn't too hard on older hardware but I can't turn it into a rush-hour mod :(
Overspark 17 Nov, 2019 @ 12:44pm 
This mod is definitely an improvement over stock behaviour. Only issue I see is that overtaking traffic likes to stay in the left lane a veeeeerry long time, while the right lane is completely empty. Any way to tweak that further?
kostial.k 17 Nov, 2019 @ 10:32am 
Hi, how can I add more traffic? Thank you
geoffccripps 15 Nov, 2019 @ 4:24pm 
Brilliant Mod Thank You :steamhappy:
TheKnoife  [author] 15 Nov, 2019 @ 11:16am 
Unfortunately no, the game can only handle one traffic_data.sii file at a time. My mod transforms traffic completely, so try it and see if you like it. Due to to added flow of traffic I ***might*** increase the AI limit but I know this game can be taxing on old hardware (like mine)
