Show us Your Interchanges!

Good work everyone, please do continue.

my first intentional approach to flex stuff:

I remember it!:D simtropolis interchange challange 2014 winter.Did you put it into Ring Of Fire?

[Abrams 1,744]

took me almost half a half day!

Behold my best interchange ever;i present you this,so hold your horses!

[kingofsimcity 5,739]

Mostly done.

[Artimus 485]

Same here, still not sure what to place around the interchange yet...

[TakemeThere 5,833]

Awesome work by all on this page  It's great to see more people making use of the latest NAM. It's what has gotten me playing the game again after taking about a month off from actual city building.

[Toby Ferrian 873]

Diamond interchange

(yes, i'm aware of that one piece of the wall facing the wrong way)

[Terring 6,473]

It's time for a little challenge, fellas.

Is it possible to build this on Simcity? And if yes, how efficient it is?

[T Wrecks 10,209]

Well, you could certainly imitate the overall layout, albeit not on such small space - which is not necessarily bad because if anything, that example looks seriously underscaled and horribly unsafe. Lanes merging so suddenly without any space for weaving, concrete walls obstructing the drivers' views - I'm not a road geek or traffic expert, but this would probaly be a nightmare IRL.

I've just finished this.

The most complex interchange I have ever created.

[matias93 7,535]

Wow, that's very impressive, and way over my skills! Talking about those, does anyone know how to do this:

(a highway-avenue overpass interchange with a central crossing, using RHW-4 as highway)

... avoiding the five-tile width weaving, or at least, keeping the central lanes straight?

Alternatively, I could do that with a RHW-6C ramp, but there is a RHW-4 to RHW-6C ramp available? The only way I've found to do that is using a RHW-6S segment in the middle, and a strange looking RHW-6S to RHW-6C ramp that shuffles to a side.

In resume, would you mind to help a poor nitpicker to archieve unneccesary highway symmetry in the game?

[Haljackey 17,270]

Sick work bruh

 

Progress.

How about this?

There are special ramps (you'll need the depreciated ones installed) that split a RHW6C with D1 Inside Ramps which I've used here. Each lane must transition using a L1 OnSlope (Flex Height Menu), and the middle RHW-2 needs a 1-Level Ramp Transition piece to connect with the avenue.

As a rule-of-thumbs, entrances and exits are usually not done in the innermost lanes. This is because those lanes are usually dedicated to higher speeds which means more accelerating/decelerating distances then the outermost lanes. It would also create confusion and be potentially hazardous as drivers wouldn't know which would be the higher and lower speed lanes.
I could only see this solution implemented in places with high traffic density , speed restrictions (no higher then 80km/h), in a high real-estate area and if the entrances/exits are always on the same side (in this case, the inner lanes).

However, these types of interchanges are particularly useful in compact areas, and in regards to the issue with the outside lanes exiting, rather than the normal with the inside lanes leaving, well-sign posted exits solves that issue.  

[matias93 7,535]

And that's precisely the situation of my interchange: it is between two curves, one of them of 90 degrees, so the speed is already reduced, maybe to 70 km/h. And to both sides there are very dense urbanizations planned, most of them not feeding cars to that intersection but crossing it, so there shouldn't be much traffic to clog that.

[rsc204 21,806]

More to the point, that's a dedicated piece made for this purpose and no other. I guess such things must exist in the real world, although I agree it's not the best motorway design.

Or another use for this kind of set-up would be if the inner-most lane was only for buses. Then this interchange would serve only buses, while car-oriented or mixed exits would be on the outsides, thus eliminating the need for buses to weave through the cars to leave or enter their dedicated lane.  (Now, we can't simulate bus lanes, but...  )

[matias93 7,535]

If there were a MIS sized no-buses filter (for lateral ramps), we could do that, combining with the existent only-buses filters for RHW-2 (for central ramps)

MGB nailed it, but I think he forgot to mention that a symmetrical RHW-6C to dual RHW-6S transition exists. I can't remember if you get it by rotating the asymmetrical transition, or if it's just further down the tab-ring (or if it's stuck somewhere like cosmetic transitions), but it does exist, and I've used it multiple times before for river crossings (dual RHW-6S bridges), and other things.

[rsc204 21,806]

Good point. I didn't mention it because simply with my design it's superfluous, unless you decide to switch back to 6S after the junction.

"Width Transitions" is the one you are looking for . It's a separate option to the regular one, next item in the Tab Ring.

[APSMS 1,892]

@rsc204 I only mentioned it because he wanted to transition back to RHW-4 it seemed, after the offramp.

A "I don't know what is it" interchange. 

Can someone help me to improve this thing?

[Tarkus 6,932]

Dusting this thread off . . .

Minor stability fix, major interchange build:

This one's almost possible with stock NAM 34 (the stability where the FLEXFly start is next to the diagonal RHW is the hang up), but 16 lines of code just now fixed that.

Up close and personal with the spaghetti:

Stack interchanges like this, where one of the mainlines goes above all the flyovers are out there--see the Kellogg Interchange and the Four Level Interchange in Southern California (thanks to woodb3kmaster for the research/inspiration).

-Tarkus

[Haljackey 17,270]

I made a short collector system to try and tackle major traffic congestion (solid red on traffic congestion view). The on/off ramps between the interchanges turned out pretty neat!

Goes to show you to keep some right of way! Only minimal expropriation was needed (near the ramps to expand them)

(I know the RHW tile below the overpass is messed up, I have since fixed that!)
