The I-87/NY-2/NY-7 SPUI in Latham, NY is marked at least this much. And the funny diamond in the center is a pavement island with "keep left" signs on it.
I like your first idea better, the one where straight-on traffic goes to the overpass. If one road goes to an overpass, and the other goes into a tunnel, I think it would work.
i know this video is two years old but just coming upon it now and learning your "7 units up+90 degree turn" method of making smooth-looking merges is a TREMENDOUS help
You’re welcome! And arterial in town, perhaps. Mixed use is good for a somewhat “main street” feel. I would avoid zoning on arterials that connect distinct towns though.
If it’s a new bridge construction, Imagine having the overpass where each side of the bridge is at a different level, then no stop lights would be needed. It would not cost much more.
Roundabouts are great, but I wouldn’t call them free flowing. Not even a turbo roundabout. I would reserve the term free flowing for grade separated interchanges or right hand turns where there is no conflict. Roundabouts still have plenty of conflict points, and cant handle as much traffic as something thats actually free flowing like a stack interchange. Roundabouts are still great though, and I do show them in this video.
Anywhere entering vehicles cross paths with traffic in the circle. A two lane turbo roundabout would have at least 8 conflict points. Free flowing is something specific, and roundabouts are not free flowing. Turbo or otherwise.
DDIs are amazing. Unfortunately, I realize a lot of DDIs being constructed in the US are oversized. They are so big you might as well build another type of interchange in its place, and they are horrible for pedestrians. The version shown in this video are the best. They significantly improve safety and capacity, take the same footprint, and the slip lanes are angled aggressively to slow down vehicles for pedestrians before going on the highway.
in terms of highway crossing monstrosity, I think I have a case for you (I don't know what that would look like in "city skyline"): here are the construction elements and constraints: the 1st and most restrictive: EVERYTHING is underground and must be drilled by tunnel boring machines the “A” motorway is a 2X2 lane on 2 levels but only one tube the Highway “B” is also 2X2 lanes in 2 parallel tubes the super interchange at the intersection allows you to access or leave the motorway (A or B) or to change motorways (A to B or B to A) This monstrosity was built in France between 1999 and 2011 and is in operation
This is very good stuff but when I look at real-world maps of big cities, I notice that even major roads have buildings "zoned". Feels kind of unnatural to build cities this way. Is there no way to mimic this in-game? I also always seem to have weak links where the arterial connects to the collectors. They are way overloaded.
When can we make something like this in city skylines 2? Ah need more mods, ive seen a few videos of how to make american interesection with deticated left and right turning lanes, but the whole entire node and intersection looks so bad with all the lines everywhere. Do you have a way to do this in city skylines 2? Thanks bud
Two flaws I have yet to see addressed, one of which has a fairly simple solution are: 1) What if someone coming off the highway needs to do a U-turn? There is no U-turn option without them having to wait, when an extra lane could simply be added to each side of the bridge to allow uninterrupted traveling. 2) The biggest flaw is trapping/delaying someone exiting the highway who wants to use a business that exists _on their side of the highway_ but on the side where traffic enters the highway. Say at 4:38 someone exits traffic from the lower left side of the screen and wants to use a business on the lower right side of the screen, they can't.
I’ll help address both! 1. Not all solutions need to accommodate a U Turn, though this one actually excels at it. Though I don’t understand why anyone who presumably missed their exit would deserve priority and not have to wait. “Simply adding a lane” is extremely expensive in real life. 2. Businesses shouldn’t really be built on interchanges. Interchanges connect high traffic roads, and a road is a place for moving vehicles. Businesses should be on smaller local streets, away from fast moving vehicles.
There's nothing wrong with an arterial t-ing right into a highway with a trumpet interchange. In fact, it's great because there are no intersections, eliminating conflict points and reducing congestion.
Amazing video, thanks for putting this together! I don't see a video like this for what assets you use (roads, parking lots, buildings, etc.). Do you have a collection for those too?
I have sort of seen the last interchange in the real world (harvey mitchell & raymond stotzer) but it was only temporary as the interchange was still under construction. Now its a diverging diamond exchange.
