For me it's the Par-clo interchange.
>>1330349>that much land wasted on cage infrastructure Rip it up and put in a rail line.
I love things that are almost good
>>1330357No left turn needed to get on the highway It is good
>>1330358>Still have two traffic lights
>>1330359Only to exit the highway, unless it's a 6 lane arterial road and you have the space you're not going to have merge on merge off interchanges. Sure full cloverleafs are cool but are inordinately expensive
>>1330358Parclo B4 > A4 >>1330359>two In effect one if it's a Parclo B4.
>>1330368What's the difference
For me, it's the High Five interchange in Dallas, TX Level I: US 75, an eight lane highway, four lanes going each way Level II: The junction of the two six-lane frontage roads, each having three through lanes in each direction, left-turn lanes and turnarounds, and easy access to US 75 and I-635 Level III: I-635, ten regular lanes, five going each way, and four HOV lanes (two going each way) separated by barriers Level IV and V: Direct connection ramps (two levels), eliminating the left exits of the modified cloverleaf
>cageway without rapid transit in the median
I just want to post this interchange because I think it's very aesthetic. Sometimes they call it the fishtail interchange. >>1330412>Rapid transit in the median and not in it's own ROWThat's a yikes for me. Who wants to walk over some interstate to get on a train? Horrible for any walkable neighborhood or TOD surrounding stations.
>>1330349Why would you make an entire thread about something so mundane and pedestrian as a goddamned highway interchange?>is this some sort of bizzarre bait?Please stop wasting threads, thanks so much.
>>1330491Fine, spaghetti road thread then
>a literal two-mile on-ramp
>>1330415>>Rapid transit in the median and not in it's own ROW>That's a yikes for me. Who wants to walk over some interstate to get on a train? Horrible for any walkable neighborhood or TOD surrounding stations.This. Transit lines on highway medians are dystopian as fuck
Here a picture of the Metropolitan expressway (Hwy.40) in Montreal in the late 70s. One of the ugliest freeways that still stands today and divides two neighborhoods and is a bitch to cross by foot or bike.
>>1331028In Toronto we have the Gardiner expressway that cuts the city off from the lake, especially in the west part of Toronto. I'd be in favour of any better pedestrian crossing over a highway
Has engineering gone too far?https://www.youtube.com/watch?v=V6iL0cIQyBk
>>1331097How come we don't have any of these in Dallas
>>1331097The thing that really bugs me about this is that only three of the four crossings have crosswalks, which makes it blatantly clear that people people who walk (and this necessarily includes transit users) are merely an afterthought, and if they exist at all are given the lowest possible priority and the least efficient route to use. Ditto for "bike boxes" - nobody is going to use those because they break traffic flow and force cyclists to wait at least one extra light cycle at a spot that may be marginally safer, but nobody who isn't already a dedicated road cyclist will be confident enough to use them, so they're a total waste of time. It's just another public space that makes it clear that if you don't drive a car there you're a second-class citizen.
>>1330349Needing redlights when highways meet 0/10 don’t recommend
>>1330387Sir Mixmaster’s a lot.
>>1330491>/n/ - Transportation >”Threads about bikes and trains only!”
>>1331146I don't really get why anyone would give a shit about buses and subway trains, either. Actual trains, maybe a little. Planes? Somewhat interesting. Boats? Ships? Meh.
>>1331156If you don't get it then why come into these threads? Just go back to your bike threads.
Here's some quality Australian road design for you.You have to go through a tram station and set of traffic lights. Instead of just taking a small ramp over and merging. Why does this country hate proper interchanges?
>>1331132>makes it clear that if you don't drive a car there you're a second-class citizen.Because you are.
>>1331069Yes the gardiner was built around the same time as the Met in Montreal. Elevated expressways in tight areas were all the buzz around 1955-70. At least the gardiner has a shoulder, the accidents on the elevated section of the met always cause huge traffic jams because of the lack of these
How would you solve this?
>>13312011. Stack interchange, but it will be ugly as fuck and probably piss off the residents2. Roundabout, not as efficient as stack, but will be much more aesthetically pleasingStoplights are the worst in terms of traffic flow, but provide safe pedestrian crossing at least
>>1331202Currently it is indeed a combination of a roundabout and many traffic lights. But these are all busy highways and traffic builds up easily.I was hoping /n/ would know some grand design to fix it smoothly.There is a live cam on the local news bc it is easy news, you always know you can report traffic there is there is nothing else interestinghttps://www.catve.com/trevo-cataratas
>>1331201Big roundabout with a few flyovers connecting the busiest sections of road
>>1331207>I was hoping /n/ would know some grand design to fix it smoothly.Replace all roads with tram lines and bike paths
>>1330415They're not perfect but they're better than nothing. Plus there's nothing more cum-guzzling-grin-inducingly satisfying than zooming past a wagie cagie stuck in traffic in a nice air conditioned train
>>1330349Whenever I see one of those I know nobody gives a shit about property values or walk score
>>1331132>It's just another public space that makes it clear that if you don't drive a car there you're a second-class citizen.True suffering. Where I live, it feels bottom-class, not even second-class, to not have a car.
>>1330356>>1330349for me its the Spaghetti loop
>>1331353I too like spaghetti
>>1331142The left right toad is an asterial road to serve the highwayProbably coming out of a residential area
>>1330349For me it's the diamond interchange
>>1331486It’s called a diverging diamond you utter pleb. A diamond intersection is something else. Diamond intersections are standard in most rural area and some more urban areas.
>>1331104Anything new like that will get put in mckinney/prosper/Frisco first
>>1331196Oh my god. I’d hate that in a truck
>>1331486are red and pink grade separated in the middle?
>>1332052No. It's attractive because it's cheap to make despite having very few phases.
>>1330349I added solar panels and tunnel access buildings
>>1332068Fuck solar, there's a nuclear plant out of shot that supplies more than enough power for a developed nation. Plant trees there instead.
>>1332062so stop lights on an interchange?
>>1332083Yes, it's not used for two motorways.
The solution to all traffic problems is reduce traffic!
>>1331132>PedestriansDon't care>BicyclistsDon't care
>>1332213>your opinionDon't care
>>1330356The intersection for trains would be 5 times bigger?
>>1331097Wouldnt a roundaobut be easier?
>>1332223Americans can’t navigate roundabouts.
>>1331097You may not like it, but this is what peak performance looks like. >>1332223>easierYou don't compare this way.If you mean how roundabouts can be easily upgraded to two-level or three-level, that's irrelevant. >>1332224A "CFI"/PFI, being signalized and with crossovers, handles like well over twice the capacity of even a signalized turbo-roundabout.Need to look up the delay.
>>1332052You are looking for this,
>>1330371A = Loop quadrant before crossing minor road B = Loop quadrant after crossing minor road4 = 4-quadrant = 6 slip roads
>>1332052Only in Baltimore. At least it used to be until it was renovated into a regular stack.
>>1332405can you summon satan with that?
>>1332410You need the M25 for that.
>>1332405This looks awful
>>1330415>left hand exits>left hand entrances
>>1332808It works with reduced traffic volumes.
>>1332818Literally anything works if you reduce traffic enough.
I like spuis. There are only 2 in my state as far as I know (Parks Highway - Seward Meridian Pkwy. and Johansen Expressway - College Rd.) but they are more aesthetic than our diverging diamond.
>>1333049The SPUI is hated by /n/imbys but having used them I think they're better than many designs that predate it but it looks like the diverging diamond is the iteration of choice these days
>>1332808dont come to connecticut thenbonus points for traffic lights on a highway
>>1333051>The SPUI is hated by /n/imbysHow?
>>1333067Probably some retarded complaints that fringies and pedestrians feel intimidated by it
>>1333137At a glance it looks bad for peds, but on closer inspection the individual crossing distances don't look too bad.
>>1333137>not just building a pedestrian walkway over itWhy not just eliminate risk altogether?
>>1333191>money is infinite
>>1333067>>1333137I don't really remember why but when I've seen threads about interchanges SPUIs always seem to be considered shitty
>>1331486Eww, weaving. Anyway, not as bad as the cloverleaf, has its uses, but not a godsend.>>1333049Based, unless you cock it up like pic related.
>>1333518>Eww, weaving.I don't see that you really weave at all in that one
>>1333527Hmm, you're right. I was referring to the middle bit where the off ramp turning left would add a lane to the surface road that also turns left onto the on ramp, like in the pic (https://www.google.com/maps/place/40.81739,-96.78766). Most designs seem to be signalised or use give way signs though, which I suppose does away with that problem.
>>1332399If both roads crosses over, it'a diverging windmill. >>1333527Try harder.
>>1333051>it looks like the diverging diamond is the iteration of choice these daysSimply because >>1333305, and that it's very specific. If you have more turning traffic or space, try to pick something else. >>1333318The junctions are usually shitty enough that an SPUI has to be used to handle them. It's not very pretty functionally, but it works, which is why I kinda like it. >>1333049Theoretically a Parclo can also be designed single-point.
>>1333067>4 pedestrian crossings required
>>1333789>pedestrian crossingsLiterally not worth worrying about
>>1333790baseddefinitely the best one here
>>1333789Very funny. Nice try. >>1333790There's this nice vid on the Radial Route 5 Tokyo-Hachioji Road joining it: https://www.youtube.com/watch?v=1obBNeKZ0DI
>>1332427It actually flows very well.
>>1333790Is that all free-floating? Can't see a single supporting pillar in the picture.
>>1334592Make an appointment with your optician, mate.
>>1332232Maximum efficiency. I like it!
>>1333057>traffic lights on a highwayfucking Breezewood...
>>1333049How do they not collide?
>>1336142No one comes close to colliding during turns. You can even see what looks like a statue in the middle of the intersection
