Let me kick off this new thread with my suggestion for an elevated SPUI tutorial, which was already partly in the RHW readme. The current entry for ground SPUI is not possible anymore with RHW 5.0, after all.



1. We'll start by placing the SPUI pieces. They're found at the back of the Avenue/RHW interface tab ring:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2FEL-SPUI%2F01a.jpg&hash=3d9bd50edbde35925cffa6ea045e79727c12a7ab)

2. In this tutorial we're dealing with a RHW-6C freeway, so leave one tile in between the pieces:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2FEL-SPUI%2F02.jpg&hash=b38fc8f54d94959a531edd75d420dbf1d0c3ac85)

3. Connect them with an avenue:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2FEL-SPUI%2F03.jpg&hash=141b8611f68722965ce0e600d45e6b87cd83d2bf)

4. Put four ground-to-elevated transitions in place, like this (beware of the correct direction):
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2FEL-SPUI%2F04.jpg&hash=8ffe776049b39ded23643a3897ee143f4e405c59)

5. The result should look like this. If you've got trouble getting the SPUI pieces to elevate properly, try to click around them to get them right. You can also bulldoze the constructor pieces by now.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2FEL-SPUI%2F05a.jpg&hash=4d9b70cb14082ae1eedd0c8c714eb25896ff47ba)

6. Drag up your RHW-6C all the way through the SPUI. You might need to place a new starter piece at the other end, but if you drag far enough, it should be allright.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2FEL-SPUI%2F06a.jpg&hash=8d1cfeaa9d7a6705afb62915f40b41f9cfbdb3f2)

7. Put some MIS-to-RHW-4 transitions there.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2FEL-SPUI%2F07.jpg&hash=7b760319a627fb6eee2ee5a86bddaebed1210d68)

8. Use D1 entrances and exits if you want to add accel/decel ramps. Otherwise, A1 pieces should suffice.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2FEL-SPUI%2F08a.jpg&hash=e9463542422c94a63dc5bbc8d26ff711ac319bb5)

9. Add the RHW-8C-to-6C pieces for the accel/decel ramps. Again, if you've got your RHW network resorting to wrong widths somewhere, click around to fix it.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2FEL-SPUI%2F09a.jpg&hash=a3b1bf1db1379340d028462894ba7f139f5efe30)

10. We're done with the RHW part now. The result so far:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2FEL-SPUI%2F10a.jpg&hash=a79c9dc1f72c663ab7aafa60f13f365cac934788)

11. Now comes the arterial part. Get a 15m hole raiser in place, like this, on both sides:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2FEL-SPUI%2F12.jpg&hash=52fc2aa4d37df311a7b6f03bba6de739862f8560)

12. Next area is up to you, but I like to use smooth ramps while not having too much of a restrictive slope mod for the avenues. That's when I use El-rail to create slopes and put an avenue in place afterwards. All up to you, of course.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2FEL-SPUI%2F13.jpg&hash=87983a34c1da57e2213240c3ccdc6c79e9af7919)

13. Get to the TULEP tab ring...
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2FEL-SPUI%2F14.jpg&hash=e8f4690a1f1f2e8999513883e4a6b619bd875682)

14. ... to find the on-slope piece at the very end:

15. Drag an avenue out of it, and put a transitional TULEP in place to close off the section:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2FEL-SPUI%2F16.jpg&hash=550ee6124bf3655f6cfeb165e64e33034413d601)

That's a very good point. Your guide is very well done. I don't think we need to review anything. The images are great and the text goes with it. Your guide's approved!  :thumbsup:

Feel free to post it in the Single-Point Interchanges (http://sc4devotion.com/forums/index.php?topic=14065.0) thread. Your section number will be 6.1 and title will be Elevated Single-Point Diamond Interchange, since it overrides the original SPUI tutorial in the RHW Interchange Guide. I'll add it to the Table of Contents once you've posted it (you deserve the credit for your guide!).

It should look something like this: Section 6.1: Elevated Single-Point Diamond Interchange. It should go at the top of your post.

Once again awesome work! A fantastic start to the submissions thread!  :)

On we go then! Here's the follow-up, for the ground SPUI that is possible with the current RHW.




In this guide, we'll be building this:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2Fground%2520SPUI%2F10a.jpg&hash=0480408fd376198bd58d4e754d9e96d8717be3c0)

1. Plop the SPUI pieces found in the Avenue/RHW interface tab ring:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2Fground%2520SPUI%2F01.jpg&hash=fcec6fb567aa07ae84514dc490561323892438be)

2. Plop four ground-to-elevated transition ramps (beware of the correct direction):
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2Fground%2520SPUI%2F2a.jpg&hash=a67e800dbaf95c66299c07e60dbf61515bac31c2)

3. Use 15m hole raiser lots to get your elevated freeway in place. You'll need to use an earthen embankment for now, as there are no ERHW 2-lane exits yet.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2Fground%2520SPUI%2F3a.jpg&hash=057fc3f593616250c559632de2a1eb9e2d923906)

4. Get RHW-4 on-slope pieces.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2Fground%2520SPUI%2F4a.jpg&hash=e1b805273ab313f3f53f73ea6006fc3dd2623934)

5. Plop four of them: two "TO ELEVATED" ones, and two "TO GROUND" ones. Like this:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2Fground%2520SPUI%2F5a.jpg&hash=17bed2f625193d24a2acf6e5c65e319448245061)

6. Repeat this on the other side, and connect them by dragging RHW across the SPUI.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2Fground%2520SPUI%2F6a.jpg&hash=9b197a5254f2c23bc6c367dc39e982db88687703)

7. Put in RHW-6S A2 exits and entrances:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2Fground%2520SPUI%2F7a.jpg&hash=1b151b5a4fc04b9c9d7f05eb5631e7bcf31771c8)

8. Drag out RHW from them, and add transition pieces at the end of the acceleration/deceleration ramps:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2Fground%2520SPUI%2F8a.jpg&hash=ee6741f3eed5b44d8878f4d9316e907b75db7226)

9. Don't forget the TULEP pieces on the arterial road:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2Fground%2520SPUI%2F9a.jpg&hash=47d15aa7089f513001bc7f3412d46e8b2e390682)

10. Now, you're done!
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1204.photobucket.com%2Falbums%2Fbb419%2Fswm666%2Fground%2520SPUI%2F10a.jpg&hash=0480408fd376198bd58d4e754d9e96d8717be3c0)

Post by: Haljackey on November 27, 2011, 08:21:15 AM
This guide looks great too! Just a few things to go over...

-Remember that this guide is meant to show how to build these interchanges as simply as possible. You get complicated by using GDO29Anagram's trick to save a couple tiles in the ramps. I would avoid that as it does take some familiarity to get used to.
-If you want to save some room, maybe consider using RHW-4 elevated to ground transitions as you did in the last guide? That way you don't need room for a MIS to RHW-4 transition.
-You can keep the entire RHW elevated. This is of course a elevated-to-ground interchange and I'd be willing to bet most are going to keep the RHW elevated past the interchange. It also simplifies the guide a bit in the pictures.
-There's a small TuLEP error in the northbound left-turn lane. The textures don't line up (you have dashed line pieces and a lone solid line piece).

I'm thinking if these get fixed the overall quality of the tutorial will improve. Don't get me wrong it's already excellent, but I feel some of these changes will make it even better! The pictures and text are very informative and accurately show what you are doing. If you have any comments regarding my review, feel free to ask if you don't think the changes are warranted.

Question: what happens to the older entries? Are they re-organised too? If so, this makes the whole guide more easy to look through and overview.

Anyway, how about some extra tips and tricks? For instance, you can make your interchanges look compact, but that isn't quite realistic. So you have to keep some distance between several (parts of) the interchanges, use certain curve radii, etc.
Title: Re: Interchange Guide Submissions
Post by: Swordmaster on November 27, 2011, 12:16:20 PM
Well, maybe we need an additional thread in this board with general tips and tricks that don't belong to any specific interchange? That way we can leave the more advanced features out of the basic guides and move them to that thread. If so, I'd agree with making it more simple.

I think that would depend on the particular situation, so it's not really crucial to the tutorial either. I just show one of the many options you have.

Now, I'll rework my original post, so keep an eye on it.

My tutorial is on 2 types of Diamond Interchanges.
Ther first one is the monst simplistic:
Plop 2 RHW-4 starters in opposite directions side by side:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg191.imageshack.us%2Fimg191%2F823%2Frandomtestcityaug270013.jpg&hash=6b0b97db2645660f5896ab5405b5346e9a386449)

Drag out the RHW and demolish the starters (optional):

Plop the elevated avenue transitions one tile away from the RHW:

And plop the EL-AVExMIS intersection in the one tile space with the el-MIS transition (not starterless) and avenue over RHW-4 puzzle pieces:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg23.imageshack.us%2Fimg23%2F7062%2Frandomtestcityjan210113.jpg&hash=86795bd1b9bd21e7f1a9442fd01e086a04dc09d4)

Extend the mis stubs 2 tiles and drag the ramps like so:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg651.imageshack.us%2Fimg651%2F2241%2Frandomtestcityfeb501132.jpg&hash=7cd7b5e8930e18cef3215115f1c69c9adddce369)

Do that 4 times and you should end up with this:

Now onto a more complecated one:
Place the starter pieces like before but with a 2 tile median. And add the 4 a-type inside ramps like so:

Add the el-MIS transitions like so:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg41.imageshack.us%2Fimg41%2F3800%2Frandomtestcityjul120113.jpg&hash=b240fa6744290f21a732b692e4610be87e84512f)

And the road ramps:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg51.imageshack.us%2Fimg51%2F1214%2Frandomtestcityjul180113.jpg&hash=1ceebe7d160bd1901521921f0ec1cde8019c34a7)

Plop the el-MISxroad and road over RHW-4 pieces:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg141.imageshack.us%2Fimg141%2F5821%2Frandomtestcityaug220113.jpg&hash=09a213f44650bdb54fc700a59e6376ad3a1eb243)

One suggestion I may make on those guides Will, is to say to make sure the lines line up if you are not using the Euro texture(like you are), because many may be using the yellow line which needs to be on the left on RHW, and if you don't have it set up that way, the traffic will not use them if they are lined up wrong(I found that out a while ago when I first started using RHW  lol)

^^ Then you check the location wide shoulder lane, which should be always on the outside (left in LHD, right in RHD). Method works with both US and Euro versions of the RHW ;)

True, so that should be mentioned as well, maybe in the tips and tricks thread.

Post by: Haljackey on November 28, 2011, 07:58:01 AM
On top of what was mentioned, these guides have already been made Will12. Check the table of contents for guides that have already been written. Section 1.1 and 1.3 covers them.

The guides on the former thread have yet to be brought over to the new section. It will take some time to move them over here (took long enough to get all the threads set up! :P)

Also it should be noted that guides should use only the minimum required downloads to show them as simply as possible. You are using the Euro textures which is not a necessity.




Swordmaster: Great job with the revised guide. It's approved. It will be Section 6.2: Ground Single-Point Diamond Interchange.

For the Tips & Tricks section:



The Cosmetic Pieces

Introduction:
The CPs (Cosmetic Pieces) one and only function is to customize the appearance of certain sections of the RHW, mostly involving special markings. Other than that, they serve no other function, however, the CPs add quite some detail to your RHWs, making them look more realistic.

Take for example this stretch of RHW-2:

With cosmetic pieces, you can replace the double center line with a broken line (with or without another solid line). You can simply plop them over an existing stretch of RHW-2. This is how the same stretch of RHW-2 looks like with CPs:

Accelleration/decelleration lanes

Another example is this RHW-4 exit. It will work fine, but it doesn't look that good or realistic.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg577.imageshack.us%2Fimg577%2F1042%2Frhwcptips01.jpg&hash=6d718ff722f379eb3b0bfaa215854f02f08d8737)

What you can do is replace a small stretch of RHW-4 with RHW-6S to create accelleration/decelleration lanes. These help drivers to slow down for an exit or speed up to merge with other traffic. Decelleration lanes don't have to be long, however, for safety reasons, keep as a standard length for the accelleration lanes of 10 to 20 tile (which will measure in RL 160m to 320m). After adding some RHW-6S stretches (including new ramps and transistions), it looks like this:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg851.imageshack.us%2Fimg851%2F9282%2Frhwcptips02.jpg&hash=0f6eb2358ca533700d09be68c0d5c37b032c40d0)

But it still looks bare. That's were CPs kick in. By adding some block markings, it's more clear that these lanes are no ordinary lanes, but have a special function. You can plop the cosmetic pieces over existing stretches of RHW, and you can also override the transistions by plopping a CP-transistion on top of them:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg20.imageshack.us%2Fimg20%2F8189%2Frhwcptips03.jpg&hash=bedeb9ea322ef6fa6099bb5a9e46dbfbce3d4cba)

Now that looks better! You can repeat the same process with other RHWs and their corresponding CPs.

NOTE: The CPs have the habbit of flattening slopes. They do have some slope tolerance, but not much. However, if you have realistic, gentle slopes on your RHW, this shouldn't be a problem.

Ramp OverPlops:
One special kind of CPs are the Ramp OverPlops. These pieces are plopped over existing ramps. For the RHW-4, there are Ramp OverPlops available for the draggable RHW Ramp types A1 and B1 (the A1 wide is corrupted at the moment). These are neccesary to connect the ramps with the NEL (Narrow Exit Lane) CPs.

First, plop down the NEL CPs over the RHW by the known method described in the previous section:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg85.imageshack.us%2Fimg85%2F4505%2Frhwcptips09.jpg&hash=a6c81825403edaf8562964f08631e34120f95b8e)

Then plop the Ramp OverPlops over the existing ramp:

Adding arrows:
If you want to, you can add arrows on the exit lanes. You can try out various styles. Here are a few examples:

Setup with only turn arrows on the decelleration lane:

Adding merge arrows to the accelleration lanes:

Remove block markings at the accelleration lanes:

Adding thru arrows:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg824.imageshack.us%2Fimg824%2F1774%2Frhwcptips07.jpg&hash=16a3acd93ce06a4ee7be755f727850923c2dbda8)

Of course, you can try out your own setups, or combine a few of the above.

Now there is an aestetic question: how far apart do I have to place the arrows? My answer: 3 or 4 tiles apart looks the best. 2 tiles apart is still OK (but not prefered). Placing the arrows right next to each other should be avoided (painting an arrow every 16m/53ft is a bit overkill)

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg651.imageshack.us%2Fimg651%2F6369%2Frhwcptips00.jpg&hash=8aa2a44a77fc347b8b445a223be90df23f89034d)

Alternative transistions:
Sometimes it's not prefered to end the outside lane of a RHW. It's quite common in Europe when freeways are narrowed down when no accelleration or decelleration lanes are involved, the inner lane (the lane with the fastest traffic) end. It's easier for fast vehicles to merge with slow ones than the other way around. There is a piece for that in the CP TAB-ring to serve this function. Note that these pieces can't be plopped over existing transistions, since they are twice as long as regular transistions:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg526.imageshack.us%2Fimg526%2F1139%2Frhwcptips08.jpg&hash=d15da6f05cb5bd5fe1c5989cd846f6f76cedbb57)

To conclude, be creative and add some detail to your RHWs!


Best,
Maarten

I decided to make a tutorial for a partial Y interchange, seeing as one hasn't been made yet. So let me know what you think:


(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg685.imageshack.us%2Fimg685%2F1534%2Fpartialytutorial1.jpg&hash=86773bf8714868b335b1b643773b1be12f0276a3)

For this tutorial we will have a RHW-6S splitting into two RHW-4s. So we'll start off by drawing some RHW-6S. Leave a 2 tile median between each carraigeway. You'll see why in the next image. Then add an orthogonal RHW-6S splitter on the opposite side of the where the two highways will split. On the other side add a diagonal RHW-6S splitter.


(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg97.imageshack.us%2Fimg97%2F1512%2Fpartialytutorial2.jpg&hash=0ca3dac71b28e2f454df4590220032fdb0e7cb1b)

Next, add a RHW-4 smooth curve on the northbound (southbound for RHD) carriageway, and draw some RHW from it. Do the same thing from the diagonal splitter piece in the same direction. this will be the carriageway splitting off from the orthogonal road. Now you can see the reason for the 2-tile median is to have enough space for the smooth curve peice. You could just have a 1-tile median if you left out the smooth curve, but it wouldn't look as good.


(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg694.imageshack.us%2Fimg694%2F231%2Fpartialytutorial3.jpg&hash=2e5ead55fe72b1b5bdc2ec1d75f8ade08058627f)

Now place a couple of RHW-4 starter peices to convert the diagonal RHW, and then build an overpass over the northbound. (southbound for RHD) It's best to convert the RHW before you build the overpass.


(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg847.imageshack.us%2Fimg847%2F5209%2Fpartialytutorial4.jpg&hash=9317036c0e314510337e3eb680184213035d192a)

Then bulldoze the RHW-4 starters and continue dragging the diagonal carriageways, and then do the same with the orthogonal RHW-6S splitter.


(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg59.imageshack.us%2Fimg59%2F8774%2Fpartialytutorial5.jpg&hash=c93614f242c29de840c72225d43d92f2905d7bcd)

To finish off, just continue the southbound carriageway northwards from the overpass, use FAR peices to bring the carriageways closer together, and there you have it! A complete partial Y interchange! You can customize the interchange, for example...


(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg827.imageshack.us%2Fimg827%2F1060%2Fpartialytutorial6.jpg&hash=3f4120c9afad0aa4d390c83ea55a3e8d5cf9af76)

You can use RHW-8 splitters instead, which adds an extra lane for traffic entering and leaving the main carraigeway. This is more realistic, especially for busier roads. With the help of a few cosmetic peices, the interchange looks much more realistic.


(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg191.imageshack.us%2Fimg191%2F4446%2Fpartialytutorial7.jpg&hash=aaacda70fb1d51b58739adda5408c02e67cfd6b2)

You can also use some smooth curves to bring the diagonal carraigeways closer together, both saving space and making the interchange more realistic.


(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg215.imageshack.us%2Fimg215%2F7538%2Fpartialytutorial8.jpg&hash=49af31da950b78ceaa3ef75268d4b1ab7777d213)

Another space-saving solution is to use FAR peices on the other side of the carriageway.


(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg269.imageshack.us%2Fimg269%2F7036%2Fpartialytutorial9.jpg&hash=7cccfd1b172ae01d31ec0b5e8ea25968ed90abdf)

Or why not turn the RHW-4 into RHW-6C?


Of course these are just a few ideas on how to customize this type of interchange. Just experiment around and see what's best for you. :) :)

You can also use a tunnel for the central RHW going straight if your RHW-4 is side by side (It currently only works for RHW-4, until the RHW FLUPs are out). The outer curve is bend away from the tunnel entrance and goes over it. Just a thought...

I did think of that while making it, but I thought this version was simpler and quicker to make. I might make another tutorial with that configuration soon. ;)

Section 8.3. Full Roundabout Interchange

For those desiring an efficient AND compact interchange between two RHW routes, nothing fits the bill like a Full Roundabout.  Although there is weaving on the roundabout (even tighter on the A1 variant shown at the end), the roundabout itself acts as a collector/distributor for the entire interchange - only requiring one off-ramp and one on-ramp with no weaving on the throughways themselves.  Even this double-C/D Monster of a 10S x 10S Full Roundabout fits entirely within a Small City Tile.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi134.photobucket.com%2Falbums%2Fq103%2FTwyla_Naythias%2FMonster_3.jpg&hash=5730cb2e72e39dfcf67b7f9db8bb52520744ab2d)


STEP 1: Positioning Markers
Plop a small marker precisely where you want the two routes to cross.  To demonstrate the versatility of this tutorial, I've opted to have an RHW-6S (2-tile network) interchange with an RHW-6C (3-tile network), thereby using a 2x3 intersection marker.  (The Monster pictured above uses a 6x6 intersection marker.)   Whatever interchange you can dream up, the only difference in construction is the size of the interchange marker.

Place five marker tiles coming diagonally off each corner of your intersection marker to help guide you on the next step.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi134.photobucket.com%2Falbums%2Fq103%2FTwyla_Naythias%2FStep1_3.jpg&hash=aa059c7715ccc5814fbf04e683a9d75de6f4ec90)


STEP 2: Roundabout Perimeter
Drag diagonal RHWs immediately adjacent to your outermost marker tiles.  Make them as long as you can without any of them actually connecting to each other - this forms the core of our C/D-type roundabout.  We'll be using RHW-4 Type B1 Diagonal ramps to access this and they can be a touch finicky, which is the reason for the extra length.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi134.photobucket.com%2Falbums%2Fq103%2FTwyla_Naythias%2FStep2_3.jpg&hash=c11094e1706eb5bd3fc6f0edeb7d5ff9c77f1046)


STEP 3: On-ramps and Off-ramps
Now we place all of our aforementioned RHW-4 Type B1 Diagonal ramps.  I've demolished some of the marker tiles to better show how every MIS ramp lines up directly with the second closest marker.  Although the proximity between on-ramps and off-ramps causes some weaving, this is restricted entirely to the roundabout itself leaving the main throughways congestion-free.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi134.photobucket.com%2Falbums%2Fq103%2FTwyla_Naythias%2FStep3_4.jpg&hash=3051774a119d5f36e4ac60d7c0356107d3352880)


STEP 4: Coming Full Circle
Now we close in gaps to complete our C/D roundabout.  I've placed additional markers to illustrate how the inside curve should extend two tiles beyond the width of the main carriageways - this is needed to preserve the RHW-4 overrides when we place our overpasses.  (It also helps to more closely resemble the circular shape inherent to roundabouts.)
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi134.photobucket.com%2Falbums%2Fq103%2FTwyla_Naythias%2FStep4_4.jpg&hash=5e25533555af35fa1ebe0593ba7255f991ab82d3)


STEP 5: Main Carriageways
Now we place the elevated transitions for our main carriageways.  The extra tiles we allotted in the previous step reinforce the overrides, enabling us to place the transitions as close as we like.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi134.photobucket.com%2Falbums%2Fq103%2FTwyla_Naythias%2FStep5_5.jpg&hash=276ac2e108a5ae0089cda487ecd95e036cf25115)
Due to RHW only having L0 and L2 heights at this time, one of the routes needs to return to ground level.  Simply for aesthetic reasons, I opted for the 'smaller' 6S carriageway - two overpasses in succession make it a tad bumpy for your Sims, so choosing the route with the lower capacity/traffic "minimizes the inconvenience".


STEP 6: Providing Access
Now we need to provide access to the C/D roundabout.  Plop MIS 45-Degree Curves coming off each of the roundabout's ramps, then place the appropriate 45° ramps coming from the main carriageways - either Type B (same RHW width) or Type E (next size larger).  For the 6C shown below, this means either a 6C-Type B or an 8C-Type E.  (The latter, of course, provides for acceleration/deceleration lanes for a bit more realism.)   
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi134.photobucket.com%2Falbums%2Fq103%2FTwyla_Naythias%2FStep6_4.jpg&hash=c7daf8c4ad51b2fe978dc3d5ce5eca50e16d24b3)
NOTE!:  There is presently a minor glitch with several of the RHW Type E Entrance Ramps whereby the preview is offset by one tile, so be sure to take this into account when placing these ramps.


STEP 7: Buttoning It All Up
Drag the main RHW Tool to button everything up - though the ramps will likely need 45° MIS Puzzle Pieces (found with the RHW Starters) - and now your Sims can enjoy congestion-free motoring throughout their world!  Compact enough that (unless you make The Monster) you still have room for four surface interchanges within a Small City Tile.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi134.photobucket.com%2Falbums%2Fq103%2FTwyla_Naythias%2FStep7_3.jpg&hash=4409ed13147793b5fbaa5322a81767452cab50c4)


OPTIONAL APPROACH: RHW-4 A1 Diagonal Ramps
For those wanting to squeeze this interchange down a wee bit smaller, you can utilize the RHW-4 Type A1 Diagonal ramps (and A/D ramps on the carriageways) to tuck the on-ramps and off-ramps in tighter.  It's a bit trickier to get A1 ramps positioned correctly (as they butt directly against one another) so you may want to practice with the original interchange before attempting this second one.

I've got to agree. Very nice guide Twyla! Practical and easy to follow.

The only comment I have is I wish there was double-height RHW pieces. That way you could make one of the mainlines sink into a trench and still have the other elevated RHW pass over it. It would get rid of the bumpy ride motorists have going over two sets of overpasses. :P

The ramp pieces are fairly close in the roundabout itself, a symptom of weaving. However since this is a roundabout and separated from the mainline, it is greatly reduced.

I'll get your guide up in the roundabouts section. Before I do I wanted to ask you about changing the name. I'd like to call it: Section 8.3. Full Roundabout Interchange (Created by Twyla)
-This is due to the fact that section 8 of the guide (http://sc4devotion.com/forums/index.php?topic=14067.msg405095#msg405095) already has a guide like this, but only one mainline actually goes through it. In your guide, both do, essentially making it a complete/full interchange.

Title: Deluxe Folded Par-Clo Interchange
Post by: Twyla on July 10, 2012, 11:35:04 PM
Section 2.7: Realistic Parclo AB Interchange

The Folded Partial-Cloverleaf Interchange (aka ParClo AB Interchange) has the same functionality as any other Par-Clo (as well as most liabilities) - however, it has the advantage of consolidating both loops on the same side.  It is also known as a Texas Turnstile due to its prolific use in Texas and other States in the southwestern US (as well as the congestion generated by two intersections on the ground route).  Many cities and towns in this region boomed along rail lines during the 19th century, with their main thoroughfares running alongside the tracks.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi134.photobucket.com%2Falbums%2Fq103%2FTwyla_Naythias%2FFP1_2.jpg&hash=e8872ec47ef287aa8aa7a01774719a520b74308b)
Obviously, this severely limited the possibilities for interchanges, but the Folded Par-Clo proved to be an economical and relatively efficient solution.  Though not as efficient as many newer interchanges, the Folded Par-Clo remains a predominant choice in locations where half the usual footprint is unavailable for whatever reason - railroad tracks, landmarks, geology, or just crotchety old landowners with good lawyers.


STEP 1: Overpasses
Given the compact nature of the Partial Cloverleafs being used, we need the overpass to provide acceleration and deceleration lanes, so we'll use the RHW-6S Transitions.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi134.photobucket.com%2Falbums%2Fq103%2FTwyla_Naythias%2FFPA1_2.jpg&hash=c41d3bb9aebb76433bcf2a17f807b29537a7608c)


STEP 2: On-ramps and Off-Ramps
Next, we plop a few RHW-6S Type E1 ramps like so.  Since we're being creative with our "deluxe interchange", we need the ramps on each side to be exactly three tiles from each other.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi134.photobucket.com%2Falbums%2Fq103%2FTwyla_Naythias%2FFPA2_2.jpg&hash=4c8ea7e7ad6250ae29db6e1edb3b3532a11b09b5)


STEP 3: Swerving and Curving
Between each pair of ramps we plop an RHW-2 Type E1 Wye - be certain it's the RHW-2, which comes later in the loop than the RHW-4 version.  With our on/off traffic now consolidated to an RHW-2, we can use RHW-2 90-Degree Curves (Large) to direct our wayward motorists towards the roadway.

Connect the 90° curve to your roadway using the Road Tool, then repeat for the other intersection.

STEP 5: Tiptoe Through the TuLEPs
Although fully functional, this intersection is exceptionally blah.  Find the Avenue TuLEP-Type A1/Road TuLEP-Type A2 T-Intersection in the TuLEPS and plop one over the current intersection, then dress up the approaches with a few more TuLEPs.  Repeat for the other intersection.

The interchange here is shown on a Small City Tile to better illustrate how small it's footprint is.




Deluxe Folded Par-Clo Interchange (aka Texas Turnstile) (NWM)
I call this a "Deluxe" interchange due to a few unusual 'tricks' used to make this interchange far tidier than most.  It also involves NAM's NWM, which is a separate mod from RHW - though many people use it, there are also a few conflicts.  Most of these deviations are quite simple and should prove easy for anyone to implement.


STEP 1: Minor Renovation
There are several instances where different mods (such as NWM and RHW) don't like each other.  Since we don't want the ugliness (or pathing disruption) which comes from failing overrides, we'll demolish four tiles of roadway (two spaces for the overpasses and one space to each side) and replace it with a Maxis Avenue.  (Besides, it's not like anyone will be making a left turn beneath the overpass.)  NWM quite tidily transitions the new Avenue back into the existing TLA-5 on its own.

STEP 2: Overpasses
Given the compact nature of the Partial Cloverleafs being used, we need the overpass to provide acceleration and deceleration lanes, so we'll use the RHW-6S Transitions.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi134.photobucket.com%2Falbums%2Fq103%2FTwyla_Naythias%2FFP3_2.jpg&hash=c76ef0f2e3c6326bed3c92be82b74eba60aafb65)


STEP 3: On-ramps and Off-Ramps
Next, we plop a few RHW-6S Type E1 ramps like so.  Since we're being creative with our "deluxe interchange", we need the ramps on each side to be exactly three tiles from each other.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi134.photobucket.com%2Falbums%2Fq103%2FTwyla_Naythias%2FFP4_2.jpg&hash=8408fa51a6ca7b1e15160486ab6c93b5d5835b4c)


STEP 4: Swerving and Curving
Between each pair of ramps we plop an RHW-2 Type E1 Wye - be certain it's the RHW-2, which comes later in the loop than the RHW-4 version.  With our on/off traffic now consolidated to an RHW-2, we can use RHW-2 90-Degree Curves (Large) to direct our wayward motorists towards the roadway.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi134.photobucket.com%2Falbums%2Fq103%2FTwyla_Naythias%2FFP5_2.jpg&hash=5937de5dc3063d98dffeb3299f7288a66e48c08e)


STEP 5: Tying Things Together
Connect the 90° curve to your roadway using the Road Tool, then plop a 3-lane Asymmetrical Road (ARD-3) Starter on it at the space indicated by the marker.  Delete ONLY the starter tile then reconnect with the 90° curve using the Road Tool.  Repeat for the other intersection.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi134.photobucket.com%2Falbums%2Fq103%2FTwyla_Naythias%2FFP6_2.jpg&hash=4a3f0c5a018c9f8d5fc14cee414495318d706c65)
Alternately, you can just plop a Road-to-ARD3 Transition against the RHW-2 90° Curve, but the technique above is a handy trick to learn when dealing with short stretches of NWM (or RHW) when the stability of overrides is an issue.


STEP 6: Tiptoe Through the TuLEPs
Conflicting overrides (look closely at the intersection above) result in an unusable intersection - fortunately, there's an easy fix.  Find the Avenue TuLEP-Type A1/Road TuLEP-Type A2 T-Intersection in the TuLEPS and plop one over the current intersection, then dress up the approaches with a few more TuLEPs.  Repeat for the other intersection.

NOTE: The addition of TuLEPS may disrupt the NWM overrides on the TLA-5.  If this happens, just plop the appropriate NWM starter in the same manner as the ARD-3 used in Step 5.


STEP 7: Being Shifty
With the ground connections done, we turn our attention back to the RHW portion.  Plop a few RHW-4S/6S transitions thusly to return traffic back to RHW-4S, making the acceleration lanes 2-3 tiles longer than the deceleration lanes (realism).

Very nice Twyla! That interchange is an example of a Folded Diamond, or a Parclo 'AB' class hybrid if you want to get technical. Never heard of a Texas Turnstile. but I can see where it fits.

I do have a few comments regarding your guide. Overall its well done, and the text and images are easy to follow.
-The inclusion of the rail line is a nice feature, but I don't think its required for this design (unless you're going for that Texas Turnstile).
-I do not list the NWM as a requirement for the RHW Interchange Guide. You have used it here (and to a quite good extent), but it is not needed.
-I do, however, list the TuLEPs as a requirement as it is absolutely needed for some designs like the SPUI guides. You do know that you can plop TuLEPs right on avenues and roads, right? I'm asking this because I see them only used on NWM networks in this design.

Quick screenshot I took of TuLEPs used on road and avenue without the use of NWM:

If it's not too much trouble, would you be able to remake the guide without NWM components or the rail line? You can still use those images at the end of the guide showing what you can do with other features.

When finished, you're guide will be Section 2.7: Realistic Parclo AB Interchange. I think it's a good fit in the Parclo section.

Thank you for your understanding. I just want to make these guides as simple and as easy-to-follow as possible, since a lot of newbies look at it.

So, I've come up with a new interchange. This one I like to call a volleyball interchange with frontage roads. If you're cramped for space and need not only an interchange between highways, but also with your city development, then this is the way to go. It conveniently fits within two crossing 4x4 sunken highway areas with one more tile on each side for a cliff so you can place some walls.

Sadly I don't have a picture-hosting site (I deactivated my Facebook account because of Timeline), so Google Drive will be the way to go on this one.

https://docs.google.com/open?id=0BzrUzfoOPCB5TXFVRjhDZHg4b3c

Once NAM 31 comes out, this will almost assuredly be updated, as I can keep all the frontage roads at L2, and then pick either L1, L3, or L4 for the raised highway.

First drag the RHW-highway (i used RHW-6S), then 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, then everything on your new hills so it looks like this:

In hope that Haljackey didn't beat me to it (he already moved the stack interchange out of the 'no tutorial' section), I'll like to show you how to build this type of interchange.




If you want, put down some rail pieces in the center of the interchange to be built. While not necessary, they may help while placing the first puzzle pieces. You may bulldoze them after the next step.

Now, select the diagonal EMIS over diagonal MIS type 1/2 puzzle pieces and place them exactly as in the picture. It's important that the orientation of the pieces is correct. The yellow lines should be pointing outwards.

Place hole digger lots for building the tunnels afterwards. It doesn't really matter if you use Avenue or OWR tunnels. Just be sure to leave enough space for the terrain for auto-conforming to the tunnel entrances, as shown with the rail.
For best results, you can build the tunnels at different levels. In this tutorial, I used the -8 and -14m diggers.

I don't believe it but I just finished posting my stack guide..... :P

Crazy timing eh? BTW your guide looks great! No problems spotted.

How about I label mine "Haljackey's way" and yours "McDuell's way".
-The key differences between our guides is that I sink my tunnels deeper and keep the ramps more basic. You keep the tunnels closer to grade but make the ramp connections a little more complex (FARHW-4 and splitters).

If you agree, go ahead and post that guide in the 'stack interchanges' thread and label it as "Section 18.2: Sunken Stack Interchange (Created by McDuell)". I'll then link it to the table of contents.

That way users will see two ways for creating this junction. With such a complicated design I think the more guides the better since they can follow the that they like better.




EDIT: Ok I see you posted it there. I edited the links and everything so crisis averted. ;)

A quick tutorial on how to build a Partial Y Interchange using FARHW and smooth to make it more compact and realistic.

EDIT: SUBMITTED TO Y-INTERCHANGE THREAD
[/color][/b]

First lay down 2 lines of RHW-6S with TWO TILES of space between them.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1243.photobucket.com%2Falbums%2Fgg550%2FDurfsurn%2FTutcity-Jan27001356463859.jpg&hash=b28742a16921569e292eabc48e9ab087c028e20a)

Now drag out from the starters and drag for 10-20 tiles. Then delete the 3 tiles of the starter piece and go to the end of the highway like this.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1243.photobucket.com%2Falbums%2Fgg550%2FDurfsurn%2FTutcity-Feb6001356463920.jpg&hash=2e6184dc76ac2cf44b81622a3ace90782e40b776)

Now go into your FARHW Menu (a subsection of the Highway Tab) and cycle through until you find this piece (I think it's called RHW-6S C1 NAM Team can help here?)

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1243.photobucket.com%2Falbums%2Fgg550%2FDurfsurn%2FTutcity-Apr26001356464105.jpg&hash=1899dec8468710fdf9d0a036032f78da3fa1e0b1)

Now add a smooth curve (RHW-4 45*) to the top of the left carriageway like so and drag out diagonal RHW from it. (If you get RHW-2 just add a starter connect it and demolish the starter)

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1243.photobucket.com%2Falbums%2Fgg550%2FDurfsurn%2FTutcity-May6001356464134.jpg&hash=1e46dc81202007629e7088bd793c9b3c0fb9c3a5)

Now start your overpass by putting the ELRHW-4 transition ramps on either side of the diagonal RHW in line with the right carrigeway.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1243.photobucket.com%2Falbums%2Fgg550%2FDurfsurn%2FTutcity-Jun24001356464261.jpg&hash=f62c162767ce3d635ee66a9dc068f07db0cfde5d)

Then you think you need some puzzle pieces for this but with new technology available in RHW 5.0 (current version of time of post)you can simply drag straight over from the ramp! (If you have problems contact the NAM team for troubleshooting)

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1243.photobucket.com%2Falbums%2Fgg550%2FDurfsurn%2FTutcity-Jul1001356464282.jpg&hash=379a9480472299a8d96e151c3fbfbebc007298e9)

Now back to your FARHW menu and pick out the RHW-4 FAR piece and add 3 to the right FARHW ramp. The 1 to the left one.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1243.photobucket.com%2Falbums%2Fgg550%2FDurfsurn%2FTutcity-Jul17001356464333.jpg&hash=fc1d3a2b2d72e08d803437ac87d4cf41412021d9)

Now at the end of the FARHW add a Short Inner Curve (The FARHW-Diag NOT the FARHW-Ortho) and drag that away.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi1243.photobucket.com%2Falbums%2Fgg550%2FDurfsurn%2FTutcity-Sep4001356464448.jpg&hash=b688b07de072bf5b937f197c644c65a7e18d16c0)

Now demolish the FARHW piece on the left ramp and replace it with a Short Outer Curve (The FARHW to ortho) and another curve again to line it up 2 spaces form the other carriageway.

Thank you Ryan.  :)

I've added the guide as section 19.1 under Full Diamond Interchanges.

However, I don't quite get why the rail stubs should be that special. There is nothing magical about them as they figure purely as a visual guidance; I could just as well have used some bus stops, water pumps, or a medium park. I normally tend to use rails as helper pieces because they are cheap and can be reached via a keyboard shortcut. It's just helping me visualize the layout of interchanges while I'm building them, especially when they are more complex.  ;)

- According to the English Wikipedia, this is a Full Diamond.
- According to the Dutch Wikipedia, it's called a Gothic Interchange.
- According to the German Wikipedia, it's a Gothic interchange, also called a Full Diamond.
- For fun, I let Google translate the Russian Wikipedia text for this interchange. They call it 'Rhombic', and the description also contains the word 'diamond'.
Now which one is really true ?  ()what()

A tutorial on building a T-intersection using RARHW for smooth curves.
__________________________________________________________________________________________________________

1. First thing to do is start with two RH-6S stubs spaced 1 tile apart.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.majhost.com%2Fgallery%2Fthebagleboy%2FSimcity4%2FT-InterchangeGuide%2Ft-interchange_guide_0.png&hash=c0f974dfcacc1aa42454ba44153fcaf40f0aa376)

2. Now to get the entrance/exit done for this side. Place one RHW-6S Type F1 Entrance on the top route and a RHW-6S Type F1 Exit on the bottom route, staggered one tile to the right. This will be important for a later step to work.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.majhost.com%2Fgallery%2Fthebagleboy%2FSimcity4%2FT-InterchangeGuide%2Ft-interchange_guide_1.png&hash=6a038d8595b17afa740972aeab8446e51b3f4402)

3. Now we are going to place some FARHW pieces. Starting from the ramp we placed in the last step, place in this order: a FAMIS-1 straight piece, a FAMIS to diagonal transition (inner), FAMIS to diagonal transition (outer), FAMIS-1-FAMIS-1 (Boomerang) curve - Outer, and finally a FAMIS>MIS long curve outer shell (small). The positions of these have all been outlined in red.

4. Now we have to transition the RHW-4 up to L1. Place 2 1-Level Flexible Height Transitions as close to the ramps as possible. Drag the L1 RHW-4 out a few tiles past the edge of the last step.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.majhost.com%2Fgallery%2Fthebagleboy%2FSimcity4%2FT-InterchangeGuide%2Ft-interchange_guide_3.png&hash=8a022cdc271f93a3e1bac98c918ec17a1fd2775a)

5. Now we'll do the last ramp for this side. Starting from the ramp from step 2, place two FAMIS to diagonal transition (inner) curves followed by two FAMIS-1 straight pieces. The 1x1 space with RHW-2 will require a filler so place that in after you have placed the other pieces.

6. We now have to get a transition up to L2. Place a 2-Level Flexible height transition 1 rile up & to the right of the last straight piece from before.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.majhost.com%2Fgallery%2Fthebagleboy%2FSimcity4%2FT-InterchangeGuide%2Ft-interchange_guide_5.png&hash=6c583e1ea6d2429b5359ff7b1451104fee79aa80)

7. Place a RHW-4 Type F1 On/Off ramp to complete this connection and to finish the 2 level height transition. You may like to place a L2 MIS starter at the top of the transition for some added stability. 3 tiles to the right, place a MIS start and drag under the L1 RHW-4 to connect up to the loop we made in step 3.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.majhost.com%2Fgallery%2Fthebagleboy%2FSimcity4%2FT-InterchangeGuide%2Ft-interchange_guide_6.png&hash=6456c4d64ce1880cf4ec9983efd892e48e4076a8)

8. Place a FLEXFly EMIS-1 (15m) type A1 piece in the space between the three networks. Drag the L2 MIS over the L1 RHW-4 and the L0 MIS. You may require a starter piece on either side for it to be stable so place one if you think you need it.

9. Time to transition everything back down to L0. Place the relevant flexible height transitions and place starters at the bottom to override the default networks.

10. Place a FAMIS-1>MIS-1 short outer curve followed by a RHW-6S Type F1 exit to connect the MIS ramp to the main route. Drag through the RHW-4 to connect the ramp to the transition downwards.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.majhost.com%2Fgallery%2Fthebagleboy%2FSimcity4%2FT-InterchangeGuide%2Ft-interchange_guide_9.png&hash=d41ff3c84dffb815e79359f9215026bea441acbb)

11. This is the last connection we have to make. Place a RHW-6S F1 exit just after the transition down the L0. Straight after that ramp, place a FAMIS to diagonal transition (inner). You'll need to place another one two tiles down and the the left. It's up to you whether you use filler pieces or try use a starter to connect the two together. Finally place a RHW-4 type F1 on/off ramp to complete the connection. Connect everything that was left unconnected and drag out the final roads. You can use FARHW-4>FARHW-4 short outer curves and a straight piece to shorted the gap between the RHW-4 route.

12. Finally the intersection is complete. Add cosmetic pieces and decorate where you feel is necessary. Now all that is left to do is enjoy your new intersection.

Nice job thebagleboy! I like that design and the effects you added highlighting tiles.

I am not sure if this falls under the T-interchange category however. It might be a T-bone as there is only one flyover ramp. If posted in the T-bone thread, it would be section 9.2.

Here's a tutorial on building a semi-directional T interchange, partly adapted from Moonraker0's excellent tutorial on the directional T.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fupload.wikimedia.org%2Fwikipedia%2Fcommons%2Fb%2Fbe%2FKnooppunt_halve_ster.png&hash=8c5f912113946511f5f79eab0bf13f266eaaadd4)

This guide will show you how to build a semi-directional T interchange between two RHW-6S freeways. It can be adapted for use with RHW-8Ss by simply using different ramps, and a variant involving RHW-6Cs is shown at the end.

Step 1: Plop two type A2 FlexRamps side by side. In NAM 32, the description of this particular FlexRamp mistakenly reads "FlexRamp Type A1", but if you press Tab six times after selecting the FlexRamps menu item, you'll reach it. In any event, it should look as follows:

(https://dl.dropboxusercontent.com/u/54771042/rhwig14.2/semi-t-01.jpg)

Step 2: Plop a two-level Flex-Height Transition immediately after the A2 ramp on the right, and a one-level Flex-Height Transition after the ramp on the left. The two level height transition may not convert to RHW-4 for its whole length; just click on part of it with the RHW tool selected to convert the rest. (I chose to align the ends of the two height transitions for aesthetic purposes, but you don't have to. If you do, however, you'll need to drag RHW-4 from the ramp to the one-level height transition to convert it to RHW-4.)

(https://dl.dropboxusercontent.com/u/54771042/rhwig14.2/semi-t-02.jpg)

Step 3: From the last cell of the two-level height transition, drag a stretch of L2 RHW-4 three cells orthogonally, then diagonally to the left. The three cells includes the last cell of the height transition and is necessary to keep the override from breaking.

(https://dl.dropboxusercontent.com/u/54771042/rhwig14.2/semi-t-03.jpg)

Step 4: From the last cell of the one-level height transition, drag a stretch of L1 RHW-4 until it intersects one cell of the diagonal L2 RHW-4, then release the mouse button. To finish the L1 flyover, drag three cells orthogonally from the other side of the L2 flyover, then drag diagonally to the right. Again, this is to keep the override from breaking. You have to drag halfway across the diagonal flyover to keep both carriageways stable.

(https://dl.dropboxusercontent.com/u/54771042/rhwig14.2/semi-t-04.jpg)

Make sure you drag both diagonal flyovers so that there is at least a two-cell span of straight, diagonal flyovers under them. Your through highway will go in this space, and you won't be able to drag it under the flyovers if they turn in that space. Refer to the following picture to see what I mean:

(https://dl.dropboxusercontent.com/u/54771042/rhwig14.2/semi-t-05.jpg)

Step 5: If you haven't done so already, curve the ends of your flyovers so that they're orthogonal and perpendicular to the direction they were originally going, as in the previous picture. Then plop a two-level Flex-Height Transition at the end of the L2 flyover, and a one-level Flex-Height Transition at the end of the L1 flyover (don't worry about the one-cell gaps between the flyovers and the height transitions; they're unavoidable when placing the transitions, and you'll fill those gaps soon enough). Don't connect the flyovers to the height transitions yet, or the flyovers may deconvert to RHW-2.

(https://dl.dropboxusercontent.com/u/54771042/rhwig14.2/semi-t-06.jpg)

Step 6: Plop another FlexRamp type A2 at the ground-level ends of the height transitions you just placed. Here's the ramp and one-level height transition:

(https://dl.dropboxusercontent.com/u/54771042/rhwig14.2/semi-t-07.jpg)

And here's the ramp and two-level height transition (as in step 2, if this height transition doesn't fully convert to RHW-4 when you plop the ramp, just click on it until the whole thing converts):

(https://dl.dropboxusercontent.com/u/54771042/rhwig14.2/semi-t-08.jpg)

You may now connect the height transitions to the flyovers.

Step 7: Drag a RHW-4 carriageway between the two ramps you just placed. Since it will pass under the two flyovers, you'll once again need to half-drag across each flyover to keep everything from deconverting.

(https://dl.dropboxusercontent.com/u/54771042/rhwig14.2/semi-t-09.jpg)

Step 8: Plop two RHW-4 inner curves in the following pattern. Make sure to leave one cell of space between one of the curves and the carriageway you just dragged. You will need to use a diagonal RHW-4 filler in the space between the two curves; make sure it has a narrow shoulder.

(https://dl.dropboxusercontent.com/u/54771042/rhwig14.2/semi-t-10.jpg)

Step 9: Plop another FlexRamp type A2 at the end of the curve you built in step 8, and drag RHW-4 from both curves to the nearest ramps, as shown in the previous picture.

Step 10: Plop two more RHW-4 inner curves in the same pattern as before, but right next to the L2 flyover. Once again, you'll need to fill in the gap between them with a diagonal RHW-4 filler. Note the same spacing between the curve and the carriageway.

(https://dl.dropboxusercontent.com/u/54771042/rhwig14.2/semi-t-11.jpg)

Step 11: Plop another FlexRamp type A2 at the end of the curve from the last step and drag RHW-4 to connect the curve to it (and to the other ramp from step 1).

(https://dl.dropboxusercontent.com/u/54771042/rhwig14.2/semi-t-12.jpg)

Step 12: Drag the other through carriageway from the ramp you just placed to the ramp from step 9. You'll have to half-drag it across the flyovers, like you did in step 7.

(https://dl.dropboxusercontent.com/u/54771042/rhwig14.2/semi-t-13.jpg)

Step 13: Drag RHW-6S carriageways out of all six ramps, away from the interchange.

(https://dl.dropboxusercontent.com/u/54771042/rhwig14.2/semi-t-14.jpg)

You're done! You can now decorate the interchange however you wish.

If you leave one cell of space between the ramps, you can then plop RHW-6S-to-6C Symmetrical transitions beyond the ramps and have RHW-6Cs leading into the interchange:

I don't mean to be a downer, but this Interchange guide is for the RHW, and you've used OWR here. &Thk/(

Also, it would help if your tutorials used zero mods (aside from the basic NAM, obviously). This is especially noticed when using the One-Way-Roads, because we can't tell which direction the roads are going, and your tutorial didn't explain this either. I'm not sure what the point of the ramps are since you can make turns on OWR, and you wouldn't be going that fast on these anyways.

Sorry if I was harsh, but it's my $0.02, and it really isn't in the right thread.

Best of luck in future then. If you're looking for somewhere that welcomes defensive, confrontational behavior and angry outbursts while refusing to speak the truth to work that could use improvement than you are probably indeed not at the right site.

I assume that i got a little bit too angry but why i got angry is because you weren't 100% honest me.The "thanks for your cooperation" hit me hard because i know what you think in real life:ah this guy is a big noob who can't make interchanges and just wasted the bandwith.And what else i noticed,no motivation for next time.Hmm what about if i make another tutorial for another interchange and then you share your opinion fully honestly,and then i regret what i said and will stay

"Thanks for your cooperation" is something I'm used to hearing as part of airport security rules, or a fire drill, or any other situation where someone is explaining rules telling you to do something but are trying to do it politely. As a staff member and stake-holder in this website (as well as someone who values being nice just for being nice) it's strongly in my interest to encourage and welcome new members and if you look through my posts I'm sure you'll find hundreds of instances of that and nothing attacking people because their newer and less experienced than I am. In fact, I don't think I've heard of anyone on any website posting something that pointless and mean. If you'd like to try again here you're certainly welcome but please don't be offended if people inform you of the rules or offer you suggestions--even if they're saying "thanks" to be polite instead of literally being thankful for something ;)

Basic tight diamond interchange(Updated design)

Step 1.I've marked the middle of the diamond interchange

Many salutations!!!  I would like to contribute a stack interchange design known as the »Quadrangle Criss-Cross« which takes into account the NAM's inability to have more than two different networks on the same tile and does not require any burrowing into the ground beyond excavating the 15 meter deep trench at whose bed the RHW rests.  Anyway, let us get right to it right away!!!

First, place a 2x2 cluster of rail tiles and draw four lengths of RHW-2 along the perimeter on all four sides; if done correctly, you should have a tic-tac-toe grid like the provided screen capture.

Second, place a 3x3 cluster of rail tiles to the outside of the RHW-2.  Follow up with a 2x2 triangle cluster to the outside of the 3x3 rail tile cluster; if done correctly, you should have something like the provided screen capture.  The triangular 5x5 cluster is very important going forward, folks; the hypotenuse of the triangle has two very important functions:  it not only guides the alignment of the left-turn ramps so that they criss-cross right in the two-tile median between the carriageways but also guides the alignment of the right-turn ramps.  Now that you know this, go repeat this on the other three corners!

Before we proceed, take a moment to appraise your handiwork.  Does it match the tic-tac-toe grid in a square shown in the screen capture?  If so, give yourself a pat on the back and get right back to work.  The third step where you draw the diagonal stretches of RHW-2 along the hypotenuse of the 5x5 triangular clusters is where you can see your hard work start to pay off; as previously mentioned, these will not only be your left-turn ramps but will guide you in adding your right-turn ramps.

If you have a tic-tac-toe grid in a square as shown in the screen capture, I have good news:  most of the tricky engineering is behind you!  Have some humility, though; we are not done with this interchange -- not by a long shot.  Even with the left-turn ramps having already been plotted out, all of that hard work will be for naught if you avail the wrong FlexFly curves.  Exempli gratia:  suppose that you designate the through lanes for the north-south highway at L0.  If that is to work, the left-turn ramp has to be at L1 at the lowest; if you carelessly employ an L0 B1 RHW-4 FlexFly, it will override the diagonal RHW-2 as such and it will be a huge headache to get that re-overridden so that there is a grade separation without having to delete the ENTIRE diagonal RHW-2 and start again.  MORAL OF THE STORY:  Before giving the mouse click to place a B1 FlexFly, confirm it once, confirm it twice, conform it thrice that you have indeed selected the correct one so that you never have to pull out the RHW Disconnect Tile and erase an entire ramp prior to redoing it.

Along those same general lines, please take a moment to proactively plan your grade separations.  The attached screen capture shows how beautiful the Quadrangle Criss-Cross can be with a little proactive planning and an eye to detail.  For this one, I had a rail line going through the western approach; upon realizing that L0 would be needed for the railway and the avenue, I made certain to avail only L1 and L2 FlexFly curves.

To help keep the elevations straight as you are doing this, please bear this in mind:

L0 -- available by default; first choice unless there is a railway or roadway across the interchange approach

L1 -- (L0 + 7.5 meters) I do not like its puny appearance; still, its short FlexHeight ramp helps to make up for this aversion (aka second choice)

L2 -- (L0 + 15 meters) I love how it stands above the terrain; still, its FlexHeight ramp requires a bit of planning for its length (aka absolute last resort for FlexFly)

L3 -- (L0 + 22.5 meters) An L1 FlexHeight ramp and an L2 FlexHeight ramp are both needed. Use only for the through carriageways.

L4 -- (L0 + 30 meters) Two L2 FlexHeight ramps are needed.  I would love to use this for the through carriageways someday when I have the necessary space ^_^

Finally, the Quadrangle Criss-Cross looks its best when the RHW-10S is availed both upstream and downstream.  An A2 egress Flex Ramp should be availed on flat ground before the interchange to lead traffic into the left-turn ramp which should then terminate with an L0 RHW-4 to MIS transition prior to a D1 ramp being availed to weave the motor traffic into the destination highway.  I take great pains to have the A2 egress FlexRamp and the D1 access ramp directly across from each other.  See the attached screen capture for reference -- though, in most cases, the Inside A1 ramps would not be there.

Right-turn ramps should both begin and end with the D2 FlexRamp which can be availed as part of an L1 or L2 elevated RHW; here again, I take great pains to have the D2 FlexRamps directly across from each other.

Please bear in mind that the FlexFly curves will gladly enjoy being placed under or over the through lanes in any configuration as long as you mind the grade separation and the proximity to another FlexFly curve.  FlexFly curves are great neighbors to orthogonal or diagonal segments of RHW but  not so much to each other.

Really annoying when this happens when you are putting in the right-turn ramps.  Try drawing out the diagonal portion of the right-turn ramp before adding the B2 45-degree FlexFly.
