ADR driver don't take ADR freights

[RIP_C.Bennington#LP_Forever]

So I have a hired driver that can drive all ADR classes, also premium freights, fragile goods and three points in distance drives. He is stationed in Frankfurt, so why he takes the garbage freights and no dangerous good from the chemical plant? Did he need a better truck?

Need luck. Since how many days is he there in Frankfurt?

AI drivers taken any load, you can't make them take specific things.

If you want them to take specific loads then you'll have to make sure the garage they are assigned to is in a city that has that type of freight. Put the ADR driver in a city that has no ADR cargo and obviously he can't take ADR.

I said he is in Frankfurt and Frankfurt has ADR's

and now he drives 600 kilometres back without a freight, omg this/my driver is so dumb

Don't get mad at him, they are all scripted. Hired drivers are there for some achievements and to bring in some more cash. As they go out on job a random one is created taking in account their skills and companies around there. The same happens on the way back plus the chance to come back empty handed. Be patient : )

Returning empty is entirely at the mercy of the random number generator (starts at 10% of the time and improves ever so slightly as the driver levels up), as is the type of cargo that your driver picks up. Just because they have a particular skill does not mean that that skill will be utilised for every job.

Think of it as a series of dice rolls - one to choose the sending company, another to choose the freight (taking into account the driver's skill levels), another to choose the receiving company, yet another the receiving city (taking account of the maximum distance imposed by their skill) with return journeys preceded by a roll for returning empty.

Incorrect. It's permenantly at 5%

Moh, does that mean that driver_no_return_job_prob in economy_data is no longer used because I still see it set to 0.1? Also, the chart below shows the percentage of empty return journeys for my hired hands across the lifetime of my main profile, which would seem to support 10% rather than 5% as the middle of the bell curve.

FWIW I have 123 drivers, a handful of them have fewer than 200 total journeys (so less than 100 returns) but the vast majority (93) have 300+ and 9 of them have 600 or more. Interestingly (at least to me) my longest serving driver, who has more than 75 in game weeks to her credit, has the third worst return percentage at 14.75% despite the fact that she's been at level 36 longer than all bar one other driver.

Update: I realised that I'd missed the total empty percentage across all hired drivers, which is 10.15% (2549 empty returns across 25,101 return journeys)

How you made that chart? : D

@kaki It's a long story :)

I have the game set up to save textual format saves as well as the binary ones, and I normally take a copy of the decrypted versions of those files (info.sii and game.sii) before and after every sleep period and once somewhere in the middle, giving them unique names in the process. Those saves are a little sketchy for the first few weeks of game time but from week 10 onwards fit the pattern described. Currently this equates to 1,785 file pairs.

I also extract the static data for each release (basically all of the .sii and .sui files in the .scs filesystems).

I then process those files (static and save) using a program 'what I wrote' which builds a full picture of the life of each driver, truck and garage in the game (amongst other things, including the static input data, city to company to cargo relationships, the current freight market and event queue, and the makeup of each truck), creating CSV files that I can load into LibreOffice and analyse.

So, the TL;DR is that that chart was created in LibreOffice from a dataset of all the driver journeys in my main profile.

Impressive : ) You like to collect and analyze data far more than me ^^' Thank you for the detailed explanation and your time of course : )

Wow impressive
