Save-independent – the mod does not fiddle with your saves, you can safely subscribe or unsubscribe at any time.
Lightweight – the mod has virtually no impact on game performance.
If you prefer the old behaviour (more dedicated turning lanes), you can enable it in the mod’s settings. ¹This is a newly introduced rule in the February 2022 update, for an even better traffic flow.
Bus lanes are not used as turning lanes for cars.
Where sharp turns (up to 50°) are present, creation of dedicated U-turn lanes is avoided.
On roundabouts, lanes are connected so that every lane leads somewhere.
Prefer dedicated turning lanes against oncoming traffic (left turns in right-hand traffic, right turns in left-hand traffic) over dedicated turning lanes in the other (collision-free) direction.
Prefer dedicated turning lanes over mixed turning-and-forward lanes.
Try to connect forward lanes 1-to-1, provided it does not violate "lane mathematics" described above.¹.
In the example above, which of the three lanes connects to 2 lanes? The mod uses a number of rules to decide, mainy:
Sometimes, this leaves a choice to be made.
3 lanes in, 8 lanes out → 2 lanes connect to 3 lanes each, 1 lane connects to 2 lanes.
3 lanes in, 9 lanes out → every lane connects to 3 lanes exactly.
Lanes are assigned using strict "lane mathematics", e.g.
The mod’s general behaviour is as follows: Numerous tutorials and guides on this topic have been published on Youtube, Steam, Reddit etc. A good road layout is of paramount importance for good traffic flow. ¹ Lane connections are a major, but not the only, factor influencing traffic in the game. ILC: Hold on, do it like this instead, *gives different instructions*. Player: ? Why is no one using these lanes? / Why are all the cars queuing in the same lane? / Why are there all these cars in the bus lane? / … Make the left lane go left and forward into the leftmost lane, middle lane go forward into the middle lane, right lane go…
