Multi Lane roads?

[Crepper441]

We have one Lane road, two lane, why not 3 or 4 Lane roads?? In the East was this normal in main Cities right? I would love that

It would require new mechanics for road vehicles, namely better merging into traffic and better lane usage. Right now road vehicles may not even use the third or fourth lane, and they would struggle to turn/merge onto a somewhat busy 3 or 4 lane road.

If you really want bigger roads, you can overlap roads in short segments to create larger roads, but mechanically it will still just be two roads next to each other.

Yeah i know waht you mean, i do this.. But i think in the Future they might add this.. in some updates.. I would like it

In a lot of cases they don't even use the 2nd lane, meaning there's currently little point in building even a 4-lane road (with parallel one-way roads).
They only change lanes to overtake or turn. And after overtaking, they don't return to their original lane, so they might end up slowing faster traffic behind them (as is common with snow plows). And conversely, traffic is not able to change lanes to pass a slower vehicle (or vehicle waiting to turn left) on the right.
And at some point the road will narrow down to 2 lanes (whether it be after a junction, or on a plain stretch of road), resulting in them having to merge, which causes jams when the volumes are high enough. This is exacerbated by the fact that before overtaking, vehicles don't consider the time it'll take for them to overtake, along with the time it'll take for them to reach the point where the road narrows. So it's possible for a car in the 1st lane to begin overtaking just before the road narrows, again potentially causing a jam..
And lastly, it's actually counterproductive for traffic to change lanes. They don't adjust their speed in order to smoothly merge into another stream of traffic. Depending on if there's a car in the lane they're changing into, they either simply stop and wait for there to be a gap in the traffic (like at an intersection), or simply change lanes, without regard for traffic behind them, potentially resulting in them getting cut off. While this might not always cause a jam, it still significantly slows vehicles down.
All of this means that the effective capacity of a 4-lane road reduces to that of a 2-lane road.
So in most cases 2-lane roads are a more optimal solution, with dedicated turning lanes if the according turning volumes are high enough.
Doubling the road to get 4 lanes is only worth considering when you have a mixture of different traffic (personal cars and heavy trucks, for instance) using the road.
And even then, for efficiency purposes, the best solution is to not to let these vehicles that significantly differ from each other (in terms of acceleration and speed) share the same road.

Hello, instead of multi-lane roads, it would be useful to have merging lanes or ones that would not block traffic when turning left.

That's already possible with one-lane roads.
To get a left turn lane, you can build a two-lane one-way road before an intersection, and a one-lane road after it. Build another one-lane road for the other direction, and you're done.
Merging lanes are also possible, but there's little point in them, since cars will give way to cars on the main road, even if they could've merged without hindering those cars.

In the Warsaw Pact, streets were built big not for traffic but for parades and aesthetic purposes . The streets were nearly empty all the time, except on the main holidays, when they would have giant parades. Having big streets, even they are only rarely used, will make cities feel orderly and spacious, in contrast to the old, twisting, claustrophobic cities of the past, socialist cities are spacious and orderly. Roads in real life were built for aesthetics, and that's what you build them for in this game.

In Moscow? Or Warsah.. there was the streets big and Full.. only in the Big Citys yes.. but they was full
