A2021 Seagull Service Interchange

Description
This is my take on a 'Seagull Interchange', or continuous green T-intersection. It connects a highway to a regular 6-lane road. Because there are no elevated roads (the entire interchange is on ground level), this interchange is very cheap.

After some testing I've found that the following settings for a Timed Traffic Light at the intersection are the most efficient:
- Three steps, with a green light for each of the three directions.
- Minimum time: 3 seconds.
- Maximum time: 20 seconds.
- Flow sensitivity: 2.

This interchange is made useing NCR and IMT. What you see in the screenshots is what you get after placing it, including the markings on the junctions. The interchange can be placed without the 'Intersection Marking Tool' mod. But without it the markings on the junctions will not be visible.

- Cost: 22.525,-
- Maintenance: 324,-
- Size: 82x45
- Max. height: 0m
- Min. height: 0m
- Nodecount: 25
- Lane mathematics are applied for a good traffic flow.
- Lane connections have been applied.

- As always; flatten the entire area the blueprint/template covers.
- Smooth out the terrain after placing.
- To fully enjoy this interchange you need to subscribe to a couple of mods. These mods do not affect your games performance. They only add extra very handy tools to your game.

Because '3-lane highways' are the most commonly used highway type on maps, I've created this interchange to be connected (the highway ends on the interchange) to these 3-lane highways. The 4th lane on the 4-lane highways are used as exit and entry lanes.

Enjoy!


Want to know how 'Lane mathemetics' work and how to use the functions of TM:PE? I recommend watching some of Biffa's traffic fixing video's on Youtube

@MaxFX: Oh, cool, thanks! Saves me some looking around. 😋 The one that I had seen, the Flow sensitivity was at 0.3, and I see on this one you've got 0.1. Wow, that should be interesting. But from what (admittedly little lol) I understand about how that works, it makes sense given the way this one is put together.

Green lines rotating in a clockwise direction,got it! 👍‍

@Dave: I've added a screenshot of the TTI setup. You need to make three steps just like it, but in each step have a different light on green while the other two are red.

Best to have the green lights go in a clockwise rotation.

@MaxFX: lol

I remember seeing in one of these interchanges that you had posted pics for another user of how you had a particular interchange set up (with timings, etc.) that might give me some clues - I remember thinking that those looked like they'd be good to use for a service interchange of that type. Granted, that was one with offramps, and this isn't, but I think it might be a good starting point. Hopefully it won't take me *too* long to find the one in question.... 😆

Well.... almost straight. It's a little curved.

@Dave: It is possible to save a lot of mod data into an asset; IMT, NCR, NA and TM:PE settings for example. But when it comes to TM:PE, I can save stuff like lane connections, junction restrictions and priority settings. But unfortunately no timed traffic lights.

In this case I believe you can do with a timed traffic light with three steps per cycle. One for each direction. So pretty straight forward.

Hint: No actually, exactly straight forward if you know what I mean. :steamhappy:

@MaxFX: I'm just turning up all over the place lately, huh? 😂

I just plopped one of these today, and that AGC taking place in the middle, instead of overpasses, got me thinking that a timeed traffic light is probably a better choice than whatever the default traffic light that the game throws on those intersections would probably be a good idea. While the lane guidance settings for TM:PE are there, if there was a timed traffic light set up on it, it didn't save with the asset. And if there wasn't, I still think it would probably be well-served by having one.... 🤔

Do you happen to have any suggestions on what settings to use here? I'm still kinda new to the whole "Timed Traffic Light" thing, so any pointers would be welcomed! 🌝

@Architect7: This is my take on the Continuous Green T-Intersection. More info (albeit in German) can be found here: https://de.wikipedia.org/wiki/Seagull_Intersection

Where does this interchange take place?
