Show us Your Interchanges!

Haljackey · March 25, 2017

So I have some beef with my city in real life.

They're taking a free-flowing trumpet interchange:

https://www.google.ca/maps/@42.9460621,-81.1246868,15.5z

...And turning it into a parclo.

The north-south road is an expressway with interchanges planned to the north. This expansion/extension will add two new traffic lights and actually make some of the existing movements less efficient.

-----

So, In SC4 I decided to attempt to make a junction that keeps the free-flowing connections so the highway remains fully controlled-access for traffic exiting and going north to avoid stoplights and vice-versa.

...And here is the result. Obviously the junction would be much more compact in real life.

And a few other close-ups

@Haljackey I think you should be submitting your idea to your local council! A much better plan!

This means....Haljackey for mayor 2017!

Is not like there isn't a precedent on the community...

I'm sure they were just planning on extending the arterial minor road past the freeway to facilitate current or future development. I think you're right when you said the traffic flow is less efficient, and I think your solution is a lot more efficient too! But I bet the town chose lower efficiency for less utilized space to minimize land acquisition costs. Plus, the traffic on the interchange, even with the expansion, is probably appropriate for the interchange design. And if there's gridlock, I guess you should submit this plan to your township council then lol!

That doesn't look cheap, though. Forget not that money is always a factor in the real world.

Watched the video series by Ganaram Inukshuk the other day and discovered a lot of new features in RHW, particularly the draggable ramps and the RHW disconnector. The draggable ramps were hard to memorize but work out very well; now I don't need to put redundant RHW starters; they are only required in the area in the middle to stablize the monster of intersections. The RHW disconnector tool is very neat; it greatly saves my time and saves me from frustration; when I was modifying little parts it prevented massive degeneration that happens with the ordinary bulldozer.

I did not plan anything, just messing around and aiming for a tight footprint, as usual...

So many roads and streets...

I'm pretty sure that this is the weirdest interchange I've ever built. Not so much because of the interchange itself, rather because of the high amount of intersections on this picture (especially with the roundabouts, they serve 6 and 7 routes, respectively). The underpass actually doesn't even work, it's just a fake because there are no FLUPs underneath diagonal RHW-4 (there's a subway tunnel allowing the Sims to get to the other side since there's no other way to get there). Hope you like this "unique" construction.

Started with this:

The tricks are to get 2 diagonal MIS starters in place (using either RHW-4 E1 or diagonal RHW-4 A1 ramp pieces, in the old Ramps tab ring), remove the stubs of L1 45 degree MIS FlexFlys, and draw the DxD crossings half by half. The FlexFly stub needs to be removed because it seems to require more space to be able to make the crossing. Watch this step-by-step gif (duration 60 sec.).

The first generation result.

An RHW 4-to-6 transition piece (upper left) was too close by the FlexFly crossing. This is how to convert these two crossings correctly.

After the first build, I thought the acceleration and deceleration lanes were too long (10 tiles) according to Haljackey's guide, so I moved the transition pieces nearer (6-9 tiles). This is the final result.

The MIS loop transition plus DxD crossing turns out to resemble a loop ramp very well... and save much space.

Here's where the tolled Highway begins:

Rosewood Highway: Pay to enter, the exit It's on our dime!

Ready for development?

Inner-City parclo:

Unique configuration:

New 4-way, emphasis on NB to WB and EB to SB connections.

Two new half interchanges

Haljackey · May 1, 2017

Triple-post. Wow, I feel so spammy and evil :evil:

...But there is a good reason for this. I have made my first 'highway interchange' video in over a year. Check it out!

4th post in a row here? I feel so lonely

Anyways, closeup on those half interchanges

Plus a new diamond

matias93 · May 11, 2017

I had to look that diamond a lot of time to get what made it so realistic... the FAR ramps are!

And to avoid the multiple posts, let me take a turn... well, maybe two turns, because RHW-2 flexflies aren't available:

This took me a few hours because of the internal BRT lanes, this one was the best configuration available. Looks rather simple, but believe me, this is more complicated than it seems...
