Na, it wouldn't work the same. You can filter out only up to five items. The filter splitter filters that items you want on one belt, and the others you won't on the other. I think this is different...

(Try running a belt into an underground belt entrance from a side.. Combine with a splitter for a lane splitter)

I tried to imagine that. Do you have a picture, how do you mean that?

BTW: Exporting of selectable map-areas as "image" and/or "loadable map" would be a really great feature, because it would enable to really talk about such special things.

Unfortunately I have been playing minecraft till now.
I doubt I'll be able to start factorio today..

Finally.
Note: The setup on the right will eat one item from each lane during initialization and won't survive items in the middle.

Ah. cool. Didn't notice till now, that the underground belt behaves like this.
.... aaaand didn't work as expected, cause my intention was, that it works also, when there is a bottleneck/jam. When the filtered output has jam, it goes into the left/right lane. With a splitter , the input just stops and no output will be done - but that's what I wanted.

Hmmmmm....

Perhaps it could work in another way: Is it possible to measure the traffic on a belt? something like a sensor.

I mean: the following two things:

- Flow (=items per second/minute)
- Densitiy (=items per meter, how much items are laying inside the sensor?)
- and perhaps a divider: Density / Items per second . This can be also called speed, see (*)

For every measurement, a limit can be set so you can put on and off smart inserters.

So, if the Speed goes down, I can switch off the input. Would be really cool and enables something like a storage. if speed is low, the inserters for the storage are turned on, and if Density is low, the inserters for the output from the storage are turned on.



(*) Flow is items / time. Density is items / lenght. The divider is then

Density
----------
Flow

which is

items/length
-----------------
items/time

so items can be reduced and remains as

length
----------
time

which is just speed (think of km/sec).

This accidental underground belt feature was more obvious with the old placeholder underground belt graphics and kept because of it's utility.
When one lane of the lane-splitter setup is blocked, it shouldn't block the other one.

I think it should be possible to detect a "belt almost empty" and "belt almost full" situations with the current smart inserters and smart chests.
One of the threads here also contains designs for logic gates built using the smart technology.

PS: I also needed a device with a similar functionality, so I built an "item capacitor"

Same concept except you can split up the 2 end and have tons of storage between.
So you do the same thing with inserters facing the other way.
They can easily fill a fast belt and fully upgraded bots easily take care of it.
