Real Traffic Density and Ratio for ETS2

Welcome to the official page of my ETS2 Real Traffic Density mod

Why a traffic density mod is necessary?

Everybody knows that the default traffic is very basic with very low density with minor differences day/night or type of roads. You can see on the official page of my mod on scs forum a chart comparison between SCS traffic and my traffic. (link not working because I am permanently banned on SCS forum and all my topics have been abusively removed. A report is on-going and a reply from SCS is still to be recieved)

you could consider also increasing g_traffic value, however this command will multiply all numbers and create therefore even smaller differences between day/night of between different type of roads. FPS is also very much affected with g_traffic

Why my Real Traffic Density mod is better than other traffic mods?

Because my mod uses rational spawn numbers according to the game’s limits checked personally in hours of testing; the numbers used at rush hours are +/- the maximum that the game can handle. The density follows real graphic charts the whole day long with peak at rush hours and reduced at night, according also to the type of the road, size of the cities, etc. Correct spawn numbers also offer a correct spawn ratio cars vs trucks vs other types of vehicles, again according to real life

Why my Real Traffic Density mod is an unique traffic mod?

it’s the only traffic mod which added motorcycles, sport and classic cars as separate type of vehicles (available of course if you use these packs). These vehicles will therefore spawn following their rules, regardless the numbers of packs used.
My traffic mod is also the only mod which brings a separate speed class for emergency vehicles and also for motorcycles and sport cars, which will drive with increased speed wherever possible (speed limit is not given by road signs). Other Ai can also break the speed limit at random basis with a certain value, up to 35% of the speed limit. Ai cannot drive faster than their limit set in their files, therefore this rule won’t really apply to trucks but rather for cars which keeps things very realistic
it's the only traffic mod which managed to keep low traffic and minimal issues on merging to motorways at very good density overal

Other characteristics of my Real Traffic Density mod

- Speed limits for existent Ai vehicles is not affected, my mod only changes speed limits for emergency, motorcycles and sport cars
- Semaphore cycle was improved to match with increased traffic density (yellow duration after green is also increased you don’t need an additional mod for this) from 1.38 1x2 and 2x1 roads have longer green for 2 lanes roads vs the one lane road within the same crossroad
- Slow vehicles can be seen with low density in traffic only in roads with 1x1 lanes and with higher density on country roads
- Classic cars and motorcycles can also be seen on country roads with low density and reduced speed
- Ai can overtake on simple continuous line on 1x1 roads


- Vanilla map and all map DLCs
- MHA Pro Map if higher priority of my mod
- ProMods with recommended addon (to be placed above Real traffic density in mod list)

for ProMods 2.52 - 2.60

- All existent Ai traffic packs; additional traffic packs are highly recommended, due to increased density you may want to see more models in traffic, not repetitive
- It does not work with Standalone Romania Map by Alex and with Standalone Hungary Map by Frank/Indian

How to use:

-most important rule: never increase g_traffic value! keep always g_traffic 1 when using this mod!!! you can use a smaller value if you want less traffic but not smaller than 0.5 which in theory will wipe out the type of vehicles with low spawn.
- place my mod above any map mods and other mods that may affect density.
- to use motorcycles, classic and sport as separate vehicles you need to rename the storage files in these mods to match with the root from my mod def/vehicle folder (see guide from ErbKaiser)
- add recommended launch options (on Steam right click on the game and click properties) paste the following line (alone or alonside other rules if you have already others, with a space in between. after years of testing these settings work the best for me with the specification that the mm_pool_size must be half of your existent RAM (I have 32 GB):
-mm_pool_size 16384 -mm_max_resource_size 50 -mm_max_tmp_buffers_size 1000 (pool size must be half of your available RAM). these settings and especially the mm_pools_size if used correctly will substantially increase performance and eliminate disturbing stuttening

Known issues not related to my traffic mod:

- merging on motorway can be sometimes slow (SCS / map mod prefab issues)
- Ai non respecting rules like semaphore (prefab issues)
- areas with no spawn or low spawn (SCS issue)
- Ai trucks indecided on which lane to be (scs bug)
- game can crash at high traffic density if many traffic pack are used (memory leak not yet confirmed, only in 1.35 and above) this error is generating the following error:
“Failed to assign pool segment “
and the solution was discussed on scs forum: (not sure if this is removed)

Why you should use another traffic density mod?

- due to its complexity, my mod is frequently affected by game updates and it may happen to cause game crash if it's not immediately updated. I offer constant support to my mod, still it might be disturbing to have a game crash and not immediately knowing the cause, or be bothered by many mod updates.
- if you don't care about a realistic traffic density or about game FPS or frame rate performances and only want to see some more traffic around, but no still you don't want 10 police cars at once by using g_traffic command

Please note:

- if other mods claims a better performance don’t fall into the fancy description, there is not magic into it, better performance means much less traffic density which also means that is not a realistic traffic mod

- whatever you read about my mods from a certain user from Roextended forum, consider it garbage news, a cheep tentative to discreditate the most subscribed traffic mod on Steam. to check you can alway open the mod files and discover the truth!

your feedback is very valuable therefore discussions can start in the comments sections below. thank you!

P.S. My mods are and will always be for free, however if you appreciate my efforts and want to offer me a beer, I thank you in advance! here is my paypal account:

it should work but the def part of promods is now smaller. use the addon or don't, it's still ok

does this mod work with promods 2.61?

That mod works with EAA map?
Cipus  [author] Jun 17 @ 3:43am 
thanks, I will keep this in mind when I update my game to 1.44

hi Cip, I discovered a issue with one toll area in Austria where cars spawn normally, but buses and trucks dissapear in this spot. Without your mod trucks and buses spawn normally. This is the location:
(sec+0000+0005);2608.98;81.3927;21385;1.19862;-0.351793. Maybe you can have a look in the future what is the cause.

I am not to familar with the values of traffic mods, I just copy pasted the post of a developer, but even if change of speedlimits on Nation roads was done by Promods, it is something France did in real life, so it's worth implementing for the sake of realism.
Cipus  [author] Jun 10 @ 9:48am 
@Frate! I aknowledge this change which was not done in SCS files. I will think about for future if I update it or not. if yes it will be in the next update of the addon. other changes that you listed do not affect in any way my mod and my Promods addon, burt I will have a close look when I update my game to 1.44
Frate Jun 10 @ 6:32am 
Cipus, there were some changes in Promods in regards to traffic:
The ProMods 2.61 has been released this morning so this is the changelogs in France for this update:

Changelogs in France:
- National road is now limited to 90 km/h instead 80 km/h.
- Rennes : the ring road is now limited to 90 km/h instead 80km/h.
- Orléans A71 : passing the speed limit camera to 90km/h on each side of the road.
- Bretagne : due to the non-presence of region sign, we've decided to add the department sign.
- Air France company can be spotted in some french airport.
- E route overlay has been added on the map.
- SCS distance signs have been replaced by our version to be more Frenchy and more realistic

The most important one is the change of the national roads to 90km/h, since it's still 80 if I use your mod. You might have to adapt your mod to those changes and there might be more changes I don't now about, so it might be worth to check, if there are more.
