@jdenm8: I tend to manage using just Windows Live Movie Maker, but as I recently found out, I had another program laying around that I never got to use: VideoSpin. It's Vista-compatible, and, other than a few premium plugins, it's free.

I may want to spend the weekend trying it for myself first, just to see how it is... :P

In the meantime, I just got a brainwave: Sometimes there are Diamond-Parclo Hybrid Interchanges. Since there's a DiParK and DDI, what would happen if you combined the two? Just a thought; Think about it for a while. ;)

Fascinating concept and tutorial Crimsonphoenix! I'm particularly interested in that diverging parclo. But why are you using flups under pedmalls instead of flups under blank terrain?

@Anagram: I meant about video-capture programs  :P

@jdenm8: Oh. I use Camstudio, and I know Ryan uses Fraps. ;)

Ah, cool. Camstudio appears to be free, so I'll look into that.

Video tutorials can be used in this guide, as long as they're clearly explained. I like pictures because I can add text to every step but if you have a mic/headset it can be done in video format as well.

I use Fraps for capturing and Sony Vegas 10 for editing. The latest version of Windows Live Movie Maker does a good job as well.

jdenm8

Yeah, I can't afford Fraps, let alone Vegas!  :D

I'll have a go at making a tutorial for the Full Cloverfold (which I cracked a while ago with the help of an unreleased NAM piece which I will be omitting) and the Half-Cloverfold.

First impressions were, "It's some sort of Whirlpool-derived Interchange."

Then I looked at it carefully... It's some sort of Whirlpool-Rotary hybrid. I don't think such an interchange has ever been attempted in SC4 before...

That looks like a fully-grade seperated version of the dutch "Turboplein" (a giant sort of roundabout). A great piece of Lithuanian engineering!

I have tried a version that started from a RHW 10 and had ramps to access the center but I stumbled on a few missing pieces :

1. I missed either a diagonal or a curved transition from RHW 4 to ERHW 4.
2. A split transition from RHW10 to RHE 6(S or C) + RHW4.

I was curious about this one because of the possibility of integrating it has a central urban piece. I hope I did spark your imaginations.

I just cleared out a large plot of land in one of my test cities. I would rather start small, perhaps a 6S to 6S Pinavia or RHW-4 to RHW-4 Pinavia. If any of us are successful with reconstructing this, post it in the "Show Us Your Intersections" thread.

Luckily, there's a 10S to 6S and RHW-4 splitter in the works. There's no curved transition for RHW-4 to ERHW-4, or diagonal transition for that matter.

EDIT: I found one crucial element to be missing as well: Elevated curves for ERHW-4 and EMIS (45-deg), preferably in the FlexFly flavour...

This is quite similar to what I'm doing with my CJ (Robenia) over at Simtropolis. The CBD for my city is placed in the usable center of the interchange. Pictures can be found here: http://www.flickr.com/photos/brickartisan/ Exp

Hello,
I've got a question. I want to make an urban highway interchange with a high capacity but with an acceptable size. I think the turbine interchange is a good option, but I don't want tunnels at the interchange because i want to use RHW6/8 and i think it drastically reduces the capacity. So is it possible to create a turbine interchange without tunnels? Or is it better to create an other interchange in a high-density urban area?

It may require some creativity and some extra space, but it may be possible...

Although you might want to consider this design as an alternative:



Or you can make a complex cloverleaf

Those intersections are very common around my area, especially on the M6.

It just depends on how realistic you want your highway interchange to be. For example, using smooth curves will make the interchange look better, but will increase its size compared with standard curves.

Here's a hybrid interchange I recently built that incorporates many features from RHW 5.0. Hopefully it gives you some ideas.

All in all, you need to play around with your junction and tweak it to be what you want it to be. It takes a lot of trial and error but in the end the results can be creative and amazing.

Anyways hope that helps!

Section 2.6: Realistic Parclo A-4 Interchange

The first tutorial in this guide since RHW 5.0's release will show you how to make a realistic parclo interchange. 5.0 has really upped the ante realism-wise, and this guide is geared to reflect that. There has never been a better time to construct realistic-looking interchanges in Simcity 4.

You will need hole digging lots for this guide. Using a slope mod is highly recommended as well.




Let's start out simple. Drag some RHW. Make sure you delete the starter pieces.
-For this guide, I am using RHW-4 with a 1 tile median. Your RHW network can be whatever size you want it to be with whatever median you want.


Get the ground lifters from the hole digging lots to do their stuff. Place 1 tile away from the RHW on each side. Drag road to set up the slope.


Demolish everything and place road stubs on your new hills.


Time to create your approach. Create a gradual assent to the top of the hills where the overpass will go. I highly recommend getting an aggressive slope mod like the RHW slope mod when you're building realistic interchanges. (I am using the bullet train slope mod here.)


Demolish your work once again and place road stubs or drag road for one tile on either side of your RHW like so. This will be the last step in setting up your approaches and will give you an extra tile below, useful for things like accel/decel lanes or future RHW widening.


Plop your avenue on-slope transitions.


Drag your avenue. At the same time, drag a couple more avenues to the side like so to set up the proper grade for your loop ramps.


Demolish the parallel networks. Plop a pair of Avenue-MIS type B ramps in a mirrored fashion.
-These pieces are new to RHW 5.0 and will drastically improve the ascetic appeal of your interchanges!


Drag MIS from the stubs and begin to curve them.


Demolish your MIS, including the stubs created by the Avenue-MIS pieces.


Plop a pair of MIS outer curves like so. Don't worry about them not connecting to the avenue-MIS ramps. That will be fixed later.


Keep curving by dragging RHW-2 from the curves. This will properly grade the next curve.


Demolish all the RHW-2 except for 1 tile near the curves. The next step is to plop a pair of 90 degree outer MIS curves directly next to the curves you just built. See the loop starting to form?


Two more MIS outer curves need to be plopped.


Connect your loop to the RHW via any ramp piece you want. I am using a RHW-4 type B ramp for simplicity's sake.
-There is room in this design for acceleration/deceleration lanes if you want to build some.


To finish the loops, carefully add in diagonal MIS filler pieces where the RHW-2 stubs are. Make sure the lines match up to form a working connection.


You can now complete your overpass if you haven't already.





Time to build the off-ramps. Two tiles away from the edges of your loop ramps, plop road stubs to level the terrain and line it up with the avenue.
-An adjustment to your avenue's slope may be required for a future intersection. I've also left a pair of extra stubs near the avenue in this example so slip lanes can be added in the future.


Demolish your stubs and begin dragging RHW-2, wrapping it around your loop ramps.


Create a pair of ramp pieces from your RHW and connect them with your RHW-2s. Then re-drag your RHW-2s and they should override to MIS.
-Again, for this example I am using RHW-4 Type B ramps.


Plop a pair of MIS inner curves at the bends of your off-ramps to complete them.





Two ramps left to go. Drag avenue as displayed to set up the proper grade for them.


Demolish your avenues. In a mirrored fashion, plop another two avenue-MIS type B ramps just before your new intersections.


Drag the MIS from these ramps toward your RHW. Connect them with a RHW ramp piece.
-I am using RHW-4 type B ramps here as well, to keep it simple for this guide.


With your last ramps in place, your interchange is functionally complete. Use road stubs to level terrain around your interchange and demolish them when complete. This will improve the raw look of your new junction.


Congrats! You've constructed a realistic parclo 'A-4' interchange!





As stated above, these interchanges can include acceleration and deceleration lanes and can accommodate wider RHWs. Here's a decorated example with a RHW-8 with acceleration and deceleration lanes:


Anyways hope you found the guide useful! Making realistic-looking interchanges with the RHW mod is now better and easier than ever!

All the best,
-Ryan (Haljackey)

Hey Haljacky,
I've got (another) question, this time about those slope mods. In the parclo A-4 intersection, do you also make the slopes of the 'leaves' with the BTM slope mod? So do you first imitate the rhw curve with BTM, and then create the road over it? Or do you also use another slope mod?
