A new cloverleaf I made

[catfriedrice 3]

Here's a monster for you.

You've got two major highways multiplexed in the bottom splitting apart to head East(top) and South(right) and a seperate highway (downtown spur maybe) headed north(left).

Very tight, but that's how I build em.

[Kusajika Yachiru 9]

That cityscape was it? Looks pretty interesting... I almost want to say it's what Simcity5 should be. Well based on the roads. But we all know cloverleafs lost their effectiveness in the late 80's to early 90's. I can't remember many but two I do recall, are no more. One in Las Vegas that is known to locals as the Sapgetti Bowl, and one in Riverside CA. I have live near both in my life and saw both of them revamped...

The traffic, was a nightmare... they worked back when traffic numbers where not in the 100,000's of cars per interchange. With the two I mentioned being about 200,000 to 300,000 cars daily.

[catfriedrice 3]

They built a 3 leaf version here between two interstates about 5-10 years ago that during morning rush hour becomes a 3+ mile bottleneck (I-40/75 @ I-140 Knoxville). It wouldn't be so bad if 140 didn't have an exit to the major E/W highway with two entrance ramps, the latter used as an extra lane to go E on 40, a clover from W 40 and a clover to W 40, then all thinned down to 1 lane to merge with SR162.

At least they took out all the cloverleafs along I-275. They were much smaller than even Maxis's size.

BTW: Who uses C and D type ramps for entrances only? Most highways I travel on have a few yards after the ramp enters a highway to allow for merging, and A & B styles don't give me that. Its the only thing about the RHW that doesn't feel realistic (that and the 1-2 car length long white dashes).

[MandelSoft 2,769]

I use the C and D ramps whenever I can. This allows you to make realistic acceleration/decelleration lanes and merging lanes.

[heitomat 156]

As Mrtnrln, I try to use only the C and D ramps, both at exits and entrances and find them to be the most realistic. My guess is that the A and B ramps were added 1) to allow the RHW system to be more flexible, and 2) because some interchanges/intersections are likely to actually have this feauture.

I agree with Catfriedrice about the white dashed lines, allthough I don't find a 1-2 car lenght line to be unrealistic. On Norwegian roads, the dashed lines are longer the higher the speed of the road. The lines could easily be 5-6 m each on roads with a speed limit of 80 km/h+, and an average car is what.. 4-5 m long?

[ROFLyoshi 1,760]

In Melbourne, we usually don't have decelaration lanes (the ramps are quite long here) but we do have acceleration lanes to merge with traffic.

[Tarkus 6,932]

We've actually adjusted the length of the dashed lines on the new "V5-Spec" RHW textures that will be in the next release (Version 4.2). They're 5m (16.4ft.) in the current public release version, and will be 4.5m (~14.76ft.) in the new texture set. The absolute minimum allowed by the US Federal Highway Administration's Manual of Uniform Traffic Control Devices (MUTCD) is 10 feet (~3.05m), and it's recommended to be longer on higher speed roadways.

Good stuff Tarkus! Cheers for that. Is there going to be variable line lengths in the Cosmetic Pieces section of the RHW?

Or is it a sceret?

[heitomat 156]

ROFLyoshi has a good point: If variable line lengths are to be added, they should be found in the Cosmetic Pieces cycle.

What I'd like to see is a split line cosmetic piece for the wider RHW network entrances; a long line facing the inner lane with a short "dot" facing the outer lane, if you get what I mean.

Found a picture:

Looking at this picture (from Oslo, Norway) it's clear that the dotted lines on Norwegian highways are only about 2,5m long (This is standard when between lanes going in the same direction). The only exception would be the split line I was mentioning..

Just saying..

[D3LM3L 0]

If you can orientate yourself in these images, this is the main interchange right before the downtown of my city. You can see the off/on-ramps into the city and some of the residential neighborhoods.

Collector lanes to avoid too much weaving.

Kelly Brown Interchange, where Parkway 95, 695, and South Street intersect:

Modeled after the 395/Southeast Freeway/South Capitol Street Interchange in DC, just much larger:

In this moasic, I am refering to the interchange at top, which is the Western terminous of the A8, the longest highway on Paridise Island:

Now I gotta find me a copy of that demo.

Be prepared to tinker with it for awhile... you can't just jump into it and start dropping and dragging roads and highways.... it not as user friendly as Sim City at all... and because its a demo.. you can't save your work... price $3,000 to $19,000 US dollars for a full working copy

^^ Actually, you CAN save your work. You just can't export it.

I jumped into it and started dragging roads and highways, but you're right. It's meant to be a professional/business software (hence the price), but it's neat none-the-less.

I mean, I started with this:

And then went to this:

based off a junction here at home.

Haven't got the hills fixed yet, I know.

The new interchange between the Airport Pky(Highway 9) and Westpark Toll:

[ROFLyoshi 1,760]

Well, I gues with that software, we can expect crazy 10-way interchanges xD

@Nathanthemayor: Nice roundabout interchange! Although I'd suggest working with the FAR-MIS to get smoother exit-entry lanes.

[Vahr 341]

I guess I'll dig out my old 6 way then

[Indiana Joe 1,750]

I'm taking the back roads to work.

[Lucario Boricua 7,027]

Well, I gues with that software, we can expect crazy 10-way interchanges xD

A 5-way interchange is already quite complex, and these are often built as a combination of 4-way with 3-way. To get an idea on the complexity of interchanges, the number of travel directions can be calculated as follows:

(n)*(n-1) where n = # of interchanging highways, for a complete interchange (all travel directions for the setup are possible)

For a general overview, we have:

2-way = (2)*(1) = 2

3-way = (3)*(2) = 6

4-way = (4)*(3) = 12

5-way = (5)*(4) = 20

6-way = (6)*(5) = 30

7-way = (7)*(6) = 42

8-way = (8 )*(7) = 56

9-way = (9)*(8 ) = 72

10-way = (10)*(9) = 90

and so on...

But, it'd be interesting to crack our brains open with such interchange models.

[Jazzmaster 716]

Been playing around with the RHW a lot lately. I'm going completely RHW in my region, and I'm really liking how much better it looks than the RHW. Some interchanges I made the past couple of days:

Expanded Diamond Interchange - [un-named highway] n-s; Jafferson Trail e-w

___________________________________________________________________________________________________

Woodlawn Interchange [not sure how to 'classify' it, I'm more or less starting to really understand how you guys do ..]

The second picture is looking from south to north. The RHW-8S to the south (top) and RHW-6S to the west (right) both encompass fictional Interstate 37. I've taken notice that the direction of the interstate that is officially designated will not change regardless of its orientation (for example, a stretch of I-275 that technically travels east-west between the Howard Franklin Bridge and the I-4 interchange 'Malfunction Junction', is still indicated as north-south).

Towards the north (bottom) of the picture, the highway turns into a MAVE-6 which forms a route I have not yet named. It's the same MAVE-6 that intersects the expanded diamond interchange in my first picture.

Best I could do on a 10 way interchange: built this last night before even seeing you mention it.

Shields added to give an understanding of how it works. Expressway heading down enters downtown across a 7 mile wide bay/river inlet. Only a few bridges span it. It's too much on the RHW (no RHW-20 yet )

And the normal 5:00PM backup leaving

[nicebutevil91 2]

How can you get CityScape?

[catfriedrice 3]

I searched for the Demo on Google and found it that way. I can't state where though since the original site is gone.

You're under the impression that somehow the shields made it "less" confusing????? I don't think it's possible.

[Alejandro24 575]

That could be a more better interchage If it were a distribution ring with all the roads connected, something as a roundabout.

But, that's totally creative.
