I wonder why nobody submitted sth like this already

Its throughput would be lower than a normal one block intersection because north-south and south-north intersect, and also because right turns are too close to the intersection.

set 1 33 trains per min

Use a circuit condition to close a signal, trains then stop on a dime. Huh? When a signal is reserved then setting it to red with a circuit is ignored till the train has passed. Anything else would be a bug. It is intentional! And the trains really do instantly stop if you change a signal right in ...

I understand that you would want to keep the intersection as is with your overall strategy. So, it either fits in the thread as is - in three pieces - or I can easily include both a 1-4-1SD(same direction) single blueprint (that loses the *any length train ability*) plus a 3 blueprint version that p...

The intersection can be a subforum post as it is now. In it's current state I don't think it would fit into aaarghas lists of 4-way intersections. As it currently doesn't allow right turns from outer lanes. Therefore it isn't a true 4-lane 4 way intersection. Easiest change would be to add right tur...

@hansjoachim: I was able to test your 2.1 rig and instructions. They are quite clear and work great. You should see about having @aaargha include it in the original post, or make a separate thread with the instructions so that you can point people to them. --- I think I will not mess with the addit...

An updated version of the test bench: New features compared to 2.0 from Aargha - Auto tester - More intuitive controls with instruction in the map view - Lamps displaying results - Lamps to indicate progress - UPS saver mode - Rounds up correctly - You can start/stop and reset from the map view - N...

You don't need the screenshot mod. I know that it isn't straight forward to use so I made some changes to the savefile, and reuploaded it to my last post, so that it is much clearer how to use. With some trainstations to explain. Alternatively you can look at the first post on this subforum. In the ...

Here is what I meant by adding waiting areas, or buffer or what you want to call them. Atm the throughput isnt that big, because right turns are limiting it, as all trains going to the right have to drive into the same lane. Adding a lane for the outer lane, like we talked about, would help with tha...

I did not incorporate lane changing in the design for two reasons. (1) Any built-in lane changer would limit the train sizes the intersection supports, and one of my goals was to ensure that it can support trains of any length without deadlocks, even if much longer trains might slow it down. (2) Le...

There were many misplaced lights which butchered the throughput, also there were a lot of unnecessary lights. I fixed it up and now it runs as best as it can. set 1 (random) 61 trains/min set 2 (planned 50% straight,15% left, 35% right) 49 trains/min set 5 (right turns only) 35 trains/min There are ...

Would it be safe to assume that widening the intersection enough to put signals in the center would achieve that?

Yes, you can just expand the intersection by a few tiles

zOldBulldog Intersection I tested your intersection Set 1 (random)= 49 set 2 (planned) = 41 Set 5 (right only) = 17 This is the result with a very good laneswitcher. With a poor one, set 1 and 2 would be lower. Right turns are this intersection's main problem. The right turns only test would have do...

[/quote] Where do you suggest the turnaround to be done then? I think its probably better at a crossing then in another place where they block traffic again. But it depends alot on the rest of the rail setup im sure. [/quote] A rail networks capacity is defined by its bottlenecks not by how many int...

I couldn't get it to work properly. Some trains reentered the mainline at a very low speed, trains entered the cyclotron while at full speed.

So what are the drawbacks? Does it work as in OpenTTD? Have you used it in a large network?

Nice work there with the tests.
Im suggesting a test that includes trains that want to turnaround and railchange.

That is possible on the test bench.
The only reason I see for adding it would be to show why you shouldn't allow U-turns or lane switching in your intersections.

above i posted an better design I looked at the intersection, its better. You made some good improvments. If you want to use in a busy area I belive that you should change a couple things. There are still three major problems I want to adresse. Left turns: Trains on the inner lane have to first tur...

I took a look at your intersection. 4way 4 lanes with any train size zero buffers Set 1= 33 trains per min Since it is a roundabout it can deadlock if trains change direction in the middle of the intersection. One annoying problem is that two trains cant take right when coming from the same directio...
