@@mattyguitar22 I'm not finding anything either. [EDIT] there's a 2 second clip of something coming soon, but I'm not having any ideas... looks like those metal poles to block traffic that they have in Europe. you can see it on the cities skylines twitter. Will be waiting for reviews to see if 1- it's something useful, and 2- how much money is involved.
24:35 "This lorry will be the first, he's gonna come down going into the city" That lorry literally made three laps before exiting to the highway, because it was forced inside
26:30 Ideally you'd want the traffic entering the round-a-bout from the left that's going out the top to use the bypass overpass since you went through all the trouble to put it in, however, because as soon as they get off the overpass they're being forced to turn left and go back the way they just came from, no one is using the bypass except for buses which get to ignore the left turn and go straight through. It also appears that next to no one is actually turning left there from what I could see, so in reality, you can just allow that lane to be dual purpose straight through and turn or remove the lane connectors just before the intersection on the side leaving the round-a-bout so they can get out of the left turn only lane. Then at least some of the people will use the bypass like the buses.
23:18 Isn't the point of the road over the top of the roundabout for cars turning left? If they were using the road properly it would make the micromanaging redundant
Looks like the the elevated lane is set to only turn left at the next intersection above the roundabout, so the traffic that wants to go straight through that intersection can't take the elevated lane.
Instead of walking paths over timed traffic lights, I add in an extra 5sec stage into the timed traffic light that stops all traffic and lets people cross. It looks a lot more realistic and still allows walkability. Try it out, it works really well!
I'm European and I might be speaking from false prejudices, but since this is supposed to be an American city I feel like they'd give a junction like this zero consideration for walkability in the first place.
@@theMosen I'm American, and I think you're giving our road designers over the past century far to much credit: they seem to actively speed time trying to make the intersections as dangerous as possible for non-car users (Mortorcycle and bus included). Cars reign supreme, and everything else is treated as an obstacle to be removed. Zero consideration would be an improvement.
I'm not sure those new traffic lights are set up correctly - seeing a lot of traffic turning across each other, particularly on that southbound intersection.
@@OujouMon That is because the node is to close to the lights. For traffic to obey the rules, you need at least enough space for a big truck in between the nodes.
Yeah I don't think this would be a superior traffic setup if the traffic was more realistic. Any one changing roads has to wait through 2 lights instead of one. It also makes the directions less logical, but it is interesting.
Hi Biffa, I noticed something a while ago, which might be influencing all your traffic to go through the main highway entrance of the city. All traffic coming from the industial area with the oil and all the big factories turn right on to the highway. They only use the two lanes that go right. It has been a while since you set up that crossing, but if I saw it correctly, the traffic can not go left to go into the city. They do not use the left lane. That might be something to look at. 🙂
When you have a T intersection, the outside lane of the T never has to have a red light. Super common here in America to let that lane be constant green and allow that through traffic to go. Limit the turning traffic to the inner lane and they will not block each other.
@@Lussimio It can be tricky; I’ve seen a couple in the states in which the outer lanes don’t have stoplights, but they have lights that flash along the crosswalks as soon as a pedestrian cues the signal at the intersection.
To help with bridge clearances instead of paging up 10 units (example) and having a steep bridge you should try going up 5 with the bridge then drop the under pass 5 to achieve the same clearance without the roads or tracks being really steep.
for most efficient timed traffic lights, set Min. Time to 1 and flow sensitivity to at least 2.0. this eliminates needlessly keeping a green light longer than necessary before changing to the next step. makes the changes dynamic based upon traffic volume
For more throughput (but lower speeds), replace the single 4 lane road with two 2 lane 1 way roads (one going from road A to road B and the other being on the opposite side going from road B to road A.
That first roundabout that enters the city is essentially a 3 way intersection - not a 4 - with the one road not connecting anywhere and can be simplified as such. Traffic is just using the roundabout to turn left and not the overpass you’ve built. A simple 3 way interchange would direct cars in ways you want them to take and not give them extra options to screw up everyone else. “They’re gettin’ in each other’s way”
He placed that road for future use, a 4 way roundabout with an unused road should not function any differently than a 3way roundabout. But yeah, he needs to fix that by-over-pass.
On your new intersections, specifically the northwest one there are cars driving straight over from west to east and cars turning left from the east on the same cycle “gettin’ in each other’s way”
17:15 I think you have a conflict with your traffic lights. when the bottom row is trying to turn left. There are cars coming from the right that want to take the road down. So it interrupts the flow.
For the first intersection: Are you sure you need that many overpass pieces? Couldn't that be solved more efficiently next to where the car overpass is? For the big roundabout at the entrance of the city: Why is the left-turning traffic not using the overpass?
I was going to say the exact same thing! There is an overpass not being used and Biffa doing what he says to not do in his city fixes, and using the Hugo There connectors on a roundabout. It's just making things harder for himself! ＼（〇_ｏ）／
They seem to be using the overpass but very rarely. And yes, that should be worth looking into. Maybe it has something to do with the t-junction in the industrial zone that's very close? But ultimately he should probably rip the thing out and place a real intersection.
24:35 The truck thats supposed to be the first one to follow the traffic pattern properly ends up going around the roundabout 3 times before taking what would have been a right turn. Cracked me up.
Heya Biffa! I always love your traffic fixes and improvements. ^ ^ Speaking of improvements: 22:00 you might wanna try two left turn lanes instead here. All right hand turns from the other side are using the overpass so they don't get in the way 25:00 a lot of cars are using the roundabout to get into the city. But why aren't they using the overpass for that?! That's why you've build that thing in the first place!
0:06 Nope, thats not you, thats how the traffic lights are build in the US. There the traffic lights for your side are on the OTHER side of the intersection.
(just me tabbing back in at 28:35 after swapping windows for a second and dribble-leaking my mouthful of tea in laughter at the extremely communicative graphic design work being done here)
Another great episode of Biffa's traffic management magic! I love seeing how all the lanes on asymmetrical junctions are being used. Good stuff and thank you very much! 👏👏👏
About the traficlight arround 17:35 . That is the american way to put the light. They put it straight across the junktion so you do not have to put your head in a weard potition to see the light on top of you if your the first on the light. So to give them the chance to see the light you need to put up the pedestrianbridge. If not they cant see the light.
Suggestion for intersection at 22:00 mark: the 2 right lanes going straight ahead don't need a traffic light to stop their movement because there's no interference from vehicles turning left as you have the two upper bypass lanes. That should keep things flowing constantly as well 😉. Love the content btw!
@ 37:16 - believe you still have a lane restriction in place that prevents the left-hand bottom lane from taking their first exit to the deadend on this roundabout. You may also want to extend the lengths of the 4 lane segments for the 2 to 3 to 4 lane transitions so they hold more vehicles that want to go straight at the intersections that were changed first.
I might be wrong but this seems to be the first Fix you created more Traffic than before the Fix 😂 *edit* ok its better. But just so you wait, you did things wich will tuck you up in the long term =P 15:20 as far as i can tell no Pedestrians have been crossing at these Junctions as you missed to setup the Trafficlights for them. Also, going from 2 Lanes to 4 you (HUGO) use one Lane to serve 3 and one Lane to serve one Lane hence they block each other. Sry but some Guy on UA-cam talks lots and lots of Trafficfixing so my Brain is stuffed with this =D
Hi Biffa. At 36:19, I can see that nobody is exiting the new highway connection at that junction, they all keep going straight into the problem one further down the road. Might want to do some "quick (lane) maffs" there. Otherwise a great video. Love your traffic fixers 😊
17:35 the reason why this is, is because you have a designation for left turning lanes where there is no road. When you spun around and zoomed in, they say "Left Turn Signal", but you have no lanes to make a left turn into. At 9:27, you turn on the Left Turn traffic light, but there is on road to turn left into. This is what's causing the Left Turn sign and traffic light facing the wrong direction. You could change the road to remove the 2 left turn lanes if you don't plan on having people be able to make left turns there at all. You're usually REALLY good at that. Every now and then, an intersection sneaks in like that.
Got me screaming the whole episode. When you mention that you added the traffic manager direction so that you don't force anyone but instead the outermost line has been forced to stay in its line.
I've been playing the same map for about 2 months. With a population of about 135,000, that incoming roundabout was always a problem. I finally replaced it with the 'Highwayend Crossing into 6-Lanes - Perfect traffic flow' junction from Predator's workshop. You might want to look at it.
Biffa, when your in Node Controller, there is a option in there called "SHIFT" to adjust the road intersection left or right. Match the colors to the intersection you want to shift, and adjustment the numbers up or down to move the road left or right. Keep it simple! Clicking it the original way!
When you add asymmetric roads for right-turns, you have the lane management set up incorrectly. You bottleneck the through-traffic to a single lane. The right land should split into two instead of the left when going from two lanes to three for a right-turn.
I don’t know what state this is supposed to be but it’s definitely not mine, you have well maintained roads with more than 2 lanes, sidewalks that actually exist, and public transport.
When asymmetrical roads don't line up correctly when reversed you don't have to delete and redraw, you can use Node Controller and change the affected node from "middle" to "bend" and it should fix itself. Great video by the way, I always look forward to new videos from you. :)
24:44 The second truck that comes into the intersection goes around the roundabout 3 times! 😂 Comes from the inside lane, doesn't slow down, does 3 laps around the roundabout, gets into the outside lane and onto the highway out the city.
Biffa fixes traffic, Yumbl creates roads and intersections, City planner plays makes perfect zonings, T4RGET and Imperatur design interesting landmarks. With their powers combines they'll make one hell of a city
Pedestrian bridges at the quadrant interchange might have been almost eliminated by use of the path connections in the bridged section. Also, overpass + roundabout - really set up badly, and you've done even worse. People already noticed, you don't have people going through overpass, and you went further to force them to go the SAME way. Also, you restricted them from turning right, they will have to go all around for that, and that will give a bit of useless traffic to your roundabout. So, anyway, you were true you've done uber traffic management, and you still missed simple things. By the way, in my practice, you could do with so much less lane restrictions with VOP, because in the sections B,C you could remove it. And the last thing, I'd rather lowered down the lane count on the trumpet, because people will already slow down to go around, they could merge to one lane each way easily. And you could easily live with 2x2 hwy from there to the city, not 3x3, and it would be easy split with all the best lane maths there.
Did you see the truck driving around twice at the roundabout while Biffa tells he goes into the city at 24:35? The truck then leaves in another direction. That was funny!
I just caugh something! 24:37 "This lorry going out the city" if you keep your eyes on it... Take the Left lane (getting out of the East junction, being at 9 o'clock for us in the video) go to the middle lane on the West Junction (3 o'clock), stay in lane South, East and North again. Switch to the outter lane on the West Junction, Go around S - E - N... Exit to the West Junction to get to the Highway! What a journey! (Probably caused by the change with traffic manager) But it was really funny that you point out the only car that totally freak out and do the round about twice! xD
And also, I would suppose that the speed on the roundabout is higher then the Vanilla Overpass road because most of cars go on the roundabout instead of using your overpass that is made exactly for that reason! (I am still at 25:03 and I hope you fix it later on!)
Hi ... 23:16 These routes show the error - the overpass is almost unused while a vast majority of the traffic examined is going to the 3rd exit / travelling 270° / turning left. Is the speed limit on the overpass higher? Can the overpass be reached from all directions on the left of the screen? Can traffic from the overpass freely choose whether to go straight on or turn left at the T-junction at/above the top of the screen? 24:05 Maybe traffic from left of the screen should be forced to take the first or second exit of the roundabout and be unable to reach the lime green lane connector. 24:27 The side street has two lanes entering the junction (right turn, left turn) - maybe it should have three instead, splitting the left turn into left/overpass and left/roundabout. The lanes are not only dedicated for the directions this T-junction offers but already for the overpass/roundabout split that happens afterwards - this remedies the lane connector issue you mention at this timecode. A similar "pre-dedication" could be done for the traffic coming from the left of the screen going straight through the T-junction. 23:20 back to the overview - it is a little bit sad you are not zooming out further. It looks as if ~95% of traffic is going straight through to your new quadruple junction. If this number is lower when zooming out, you could try to offer vehicles alternatives to joining the ex-stroad. 35:47 These routes look like a great success - but you do not follow the routes ... 37:11 The vehicles should get off the highway here and take the bridge across the river to the city. I have the impression they don't and still use the overcrowded roundabout instead. Also 37:11 - the left turning lane from Fawn District to the bridge looks unused (unreachable?) - check lane connectors at the node (top left of screen) where the two two-lane-one-ways merge into the 3+2 road. I think there was a issue with the Ctrl-S shortcut for lane connectors producing strange results weeks ago.
18:47 Biffa check your light sequence, you have traffic turning left across oncoming traffic with both lights green. The traffic will work more like you thought if they don't cause each other to brake I do realise that you may have fixed this in the last 8 months 😂
7:02 I think you don't need the time traffic light at the crossroads on the far right. Before the rebuilding there wasn't enough space between this crossing and the big one, but the big one doesn't exist anymore. I think a give way sign should be better here 7:40 Is that enough space for those turning left? If many people want to drive straight on here, they block the way for those turning left, either they have to get into the right lane at the last intersection (i.e. one lane for the left and one for straight on) or enough space to change lanes here 24:37 You're forcing cars into the roundabout, they can't turn right immediately. And please look at the truck that enters the roundabout from the left on the left lane here, it goes completely around the roundabout twice before exiting it. Maybe it's just confused by the changes, but better double check. And I think you should increase the speed from the bridge, if people want to go into the town they should use that bridge and not the roundabout or do they have some other reason not to use it?
That unused 4th exit from the main roundabout is just begging to be creatively hooked up to the highway. I'm loving these link roads with the little tunnels and custom intersections though, very cool and you get to work with the land so much better than just flattening everything to try to fit in a stock intersection. Nice work!
Having 2 interchanges from the same highway right next to eachother connecting to the same roundabout separately just creates a lot of unnecssary crossover. You generally want to give people options to do DIFFERENT things. otherwise you're just adding tarmac and complications. That road should be reserved for future expansion. Although splitting his current highway interchange into 2 roundabouts connected by that road could be a good thing. It's how most modern european interchanges are built now.
@@heygek2769 He could reconfigure it so the existing connection is inbound traffic only and the currently unused is outbound only, or have each connection service one side of the highway. There's so much traffic funnelling through that one connection with a completely disused highway-sized spur right there. But yes you're right, redundancy for the sake of it is generally not a great idea.
11:30 - your lights are misconfigured. You can see left turn traffic crossing while straight through is crossing from the other direction on both sides of this interchange.
Having picked up the game again for the first time in a number of years I must say your AA solution is impressive. I'll be taking a look at your mods/order!
26:40 Biffa! Just make that nothern intersection only go straight on, no left hand turns. That intersection's left hand tunrns are forcing the bypass traffic to take a left there, which basically none will ever need because they have an intersection right before the roundabout they are more likely to use. Traffic from the highway can either go straight through the roundabout and make the next right, or use the second intersection to the north to make a left into the city. Same with traffic coming from the south, which doesn't actually exist yet. And because all the roundabout's traffic from the west will have a bypass that lets them go left, the conflict on the roundabout will be significantly reduced for the other directions even with that northern intersection disallowing left hand turns. Also, if traffic is still a problem even after this change, I would suggest a traffic circle (lighted roundabout) before entirely replacing it. Easier to do and it may just work.
20:45 The lanes are wrong. The left lane should only be for the left straight lane, the right lane should split into straight and right turn. You won't get the people blocking the lanes on the left side this way.
I'm going to keep banging on about using node controller on roundabout entries until Biffa finally listens to me! Cars are really slow getting onto your big roundabouts because they're so far from the entry!
Node controls: use shift to line up intersection, then select middle node (which will only have one dot), shift to select, and then select dot from previous node. I'm sure I've seen Biffa do it dozens of times, he was just juggling a lot of thoughts 🙂
At 17:33, the traffic lights are not facing the wrong way. In the US, especially with overhead lights, the lights are placed on the far side of the intersection so you can look straight at them. Otherwise, the light would be directly above the first car in line and they wouldn’t be able to see it.
You would probably like Workers and Resources: Soviet Republic. They're coming out with a garbage update and metro systems soon. It is really, really cool.
The new interchange you built is weird because it goes from a highway down to an arterial and then right into the interchange. A system interchange like a trumpet would make more sense and remove the need for a traffic light there
Why not reverse the overpass at the main traffic circle. Turning right is only 1 exit on the circle but the people backing up to go left have to go around the entire circle. If you switch them it should be fixed. Or make the lane at the end go straight, not just a left turn
I was going to comment on the overpass east to north not being used (on the main incomer roundabout) due to issues north of it, and people seem to have discovered the next intersection forcing that route to go left only. That is what's causing a lot of the traffic on that roundabout being so busy! Good luck fixing that.
Two things could be going on here. It sounds like they can't get into the 'right' lane and yet still want to follow their route. 1. the busses could be forced into that lane (something with lane restrictions or dedicated bus lanes?) 2. the busses can't get into the lane they should be in because of Hugo There, disallowed lane switching Do you use any mods that influence traffic and/or mass transit?
@@lordrork5884 thank you I haven't played for 3 months or some and I knew there were updates but I have not seen this feature. I unchecked it, thank you once again for helping. I'll change the comment
At at 23:11 Is the over pass a 1 way or 2 way because it looks like the cars aren't using it (to go into city from industrial) also the truck just went around maybe 3 times
2:40 - Biffa, set your timed traffic lights up with : Min : 1 Max: 10 (change to how long you want green) Type: No one is driving Sensitivity : medium You will find traffic will flow more freely, especially when no on is driving, the lights cycle quickly, but allow banked up traffic clear. The max time allows for more throughput than waiting.
the lights setup depends on a myriad of factors, like the road's purpose (arterial, collector, local, ect), traffic volume, ect. the way the lights run here (in the great lakes region, at least) is rather long green/red cycles, between 15 and 30 seconds (25 is common at highway junctions). what you have listed is something i would most likely use at two collectors crossing one another, unlike the Quadrant Interchange like what Biffa has set up in his video.
I think running a highway where the busy road is at might be a good solution. That's really common in us and although it might not be the best looking, it does work👍
Your Lane Mathematics is slightly off in one crucial place. at 15:31 for instance, whenever you have 2 lanes approaching the intersection, with the turn on the right, you are forcing both lanes that want to go straight, to merge into one lane, then they can spread out to two again before the intersection. In that clip, on the left, the blue connection needs to be dedicated, and the pink one needs to split into two. And on the right, the green needs to be dedicated, and the blue splits into two. The red could split into going straight or turn lane for max flexibility. This would also need to be done coming from the "North" on the other road.
Yay fix it video! For the roundabout, maybe could use 3 lanes in the roundabout. I think I e heard you say in old fix it videos to always have 1 more lane in the circle than the roads feeding into it.
Take a look at New Jersey jug handles! I use them in my cities and they work like magic. Instead building an overpass I’d keep the 4-way intersection and restrict traffic to only go straight or right. If they want to turn left they have to use the “jug handle”
on your new three-way junctions, i think you have the traffic lights restricting the flow of lanes that it doesn't need to restrict. For example, traffic coming from the west, and turning south, will never need to wait. At each set of traffic lights, it crosses no lanes (essentially, it could be a dedicated lane and not interact with the lights at all). I would try dedicating a single lane for right-hand turns, and have the *other* lane for traffic that the lights controls. Same for straight on, on the north-south road, and the east-west road. It seems like it would flow without interrupting most of the traffic. EDIT: that section at 23:10 where you check where everyone is going, and then amend the lane management to accommodate the volume of traffic going into the city... The overpass that is bypassing the roundabout SHOULD be taking all that traffic. only traffic that is leaving the city or taking the other (as yet unused) junction should be going to the roundabout. EDIT2: The above edit means that the traffic entering the city from the highway should have an uninterrupted entry onto the roundabout, as there'll be nothing approaching from their left to stop them (at least until that unused section becomes used).
Just FYI - you've set up the quadrant interchange timed traffic lights incorrectly. You've got left-turning traffic and straight-on traffic going at the same time, which shouldn't happen. You NEARLY copied Yumbl's setup, but got one of the phases wrong. You'll probably need to look too at the interchange bringing traffic from the northernmost highway down through your industry area - that little off-ramp etc. leads into a major 4-way interchange, which the traffic doesn't seem to like using much - so your trucks are still going via the fastest route down through the same roundabout they were using in the first place. You didn't really have time to get to that though, so I'm hoping you will! Love the content, as always!
The space between your new trumpet interchange and the border of the new square would be a great place to fill your industrial need and place something like the giant trash burner - far from other uses that hate the pollution, but not that far from the city and great road access
19:00 "That is working fine!" - It really feels like it's just not: Your queues are still super long and if anything you will end up adding more traffic in the future: 10 bucks says you'll have to come back here again in the future and to a partial cloverleaf or an actual full interchange later anyways.
With these junctions you can always give each right-most lane the ability to always go through (permanent green light) by giving them a lane only they can go into. What i mean is the topmost lane of the T and both right inside turns. They do need their very own lane coming out of the junction. But it's a great bypoass where needed.
That main roundabout at the entrance to the city needs to be upgraded to a turbo roundabout. Should help the traffic as it is now, essentially giving each direction its own lane. But when yiu start using that other road, you'll really want a parclo in there. Yumbl is just fantastic, he really knows his stuff
The partial interchange is quite common in the older, denser parts of the US, like New Jersey, Philly, B'more and DC areas. It is "easy" to upgrade an intersection to a much higher traffic throughput with the single diamond leg and is a smaller amount of land "taken". There are many on little two lane roads too.
For your new highway interchange, consider realigning the existing highway entering from the northeast (I think??) straight into the new highway. That would seem to be the dominant movement. Traffic on the existing highway coming into town from the opposite direction already has a route into the city, so this could be simplified with a fly-over ramp for any through traffic on the existing highway. I don't know that you'd need a full system interchange here, unless you want it for symmetry's sake.
28:06 the trucks leaving the unique factory area are still being forced to turn right because you made a mistake with dedicated lanes. That’s clogging up the original highway junction more than it needs to.
I’m sure it’s been said but in America, we have ‘right on red’. So anyone turning right at an intersection with a traffic light can treat it like a yield. That means 3-way / T junctions flow much smoother. Aldo, your overpass on your entry roundabout isn’t being used from the industry into the city. My guess is the lanes from the intersection are the cause.
Thats a great spot for the quadrant interchange! Well done 😃
Thanks for the idea and introducing me to a new style interchange! 😊

I was lolling hard at that lorry =)) I bet if biffa loads up this save now, that lorry is still going round-round-round-and-about
26:30 Ideally you'd want the traffic entering the round-a-bout from the left that's going out the top to use the bypass overpass since you went through all the trouble to put it in, however, because as soon as they get off the overpass they're being forced to turn left and go back the way they just came from, no one is using the bypass except for buses which get to ignore the left turn and go straight through. It also appears that next to no one is actually turning left there from what I could see, so in reality, you can just allow that lane to be dual purpose straight through and turn or remove the lane connectors just before the intersection on the side leaving the round-a-bout so they can get out of the left turn only lane. Then at least some of the people will use the bypass like the buses.
I came here to say exactly the same thing. Get people using that and the roundabout won't be an obstacle.
I noticed that too
As above, or just make that junction after the roundabout a no left turn from the flyover side.
Yup. Potentially look at the speed limits to make sure the overpass is not slower than the roundabout
Great eye! I missed that

@@Sungirl801 I'd guess they're probably being forced around the roundabout somewhere with the overpass being shorter unless the speed is really low!
I believe they are being forced to turn left when going down, so they are trying to avoid it by going through the roundabout and going straight
@Biffa Plays Indie Games please check it
Looks like the the elevated lane is set to only turn left at the next intersection above the roundabout, so the traffic that wants to go straight through that intersection can't take the elevated lane.
Biffa 26:45 they are not using the bypass lane because you are forcing them to turn left at the next intersection. which is on the left of the screen.

Instead of walking paths over timed traffic lights, I add in an extra 5sec stage into the timed traffic light that stops all traffic and lets people cross. It looks a lot more realistic and still allows walkability. Try it out, it works really well!
He could have just used the overpass, connect a few paths, badabing bada boom, pedestrians can go in all directions.

@@fluitfluiten Is that why? I assumed it was because he toggled on "you can go through" mode.
Yeah I don't think this would be a superior traffic setup if the traffic was more realistic. Any one changing roads has to wait through 2 lights instead of one. It also makes the directions less logical, but it is interesting.

Hi Biffa, I noticed something a while ago, which might be influencing all your traffic to go through the main highway entrance of the city. All traffic coming from the industial area with the oil and all the big factories turn right on to the highway. They only use the two lanes that go right. It has been a while since you set up that crossing, but if I saw it correctly, the traffic can not go left to go into the city. They do not use the left lane. That might be something to look at. 🙂
When you have a T intersection, the outside lane of the T never has to have a red light. Super common here in America to let that lane be constant green and allow that through traffic to go. Limit the turning traffic to the inner lane and they will not block each other.
Pedestrians would like to have a word
@@Lussimio
It can be tricky; I’ve seen a couple in the states in which the outer lanes don’t have stoplights, but they have lights that flash along the crosswalks as soon as a pedestrian cues the signal at the intersection.
@@Lussimio It's America
@@Lussimio He put in 2 overly gigantic pedestrian bridges. There's no need to worry about crosswalks.
@@Lussimio Pedestrians have the bridges
To help with bridge clearances instead of paging up 10 units (example) and having a steep bridge you should try going up 5 with the bridge then drop the under pass 5 to achieve the same clearance without the roads or tracks being really steep.
for most efficient timed traffic lights, set Min. Time to 1 and flow sensitivity to at least 2.0. this eliminates needlessly keeping a green light longer than necessary before changing to the next step. makes the changes dynamic based upon traffic volume
For more throughput (but lower speeds), replace the single 4 lane road with two 2 lane 1 way roads (one going from road A to road B and the other being on the opposite side going from road B to road A.
That first roundabout that enters the city is essentially a 3 way intersection - not a 4 - with the one road not connecting anywhere and can be simplified as such.
Traffic is just using the roundabout to turn left and not the overpass you’ve built. A simple 3 way interchange would direct cars in ways you want them to take and not give them extra options to screw up everyone else.
“They’re gettin’ in each other’s way”
He placed that road for future use, a 4 way roundabout with an unused road should not function any differently than a 3way roundabout.
But yeah, he needs to fix that by-over-pass.
On your new intersections, specifically the northwest one there are cars driving straight over from west to east and cars turning left from the east on the same cycle “gettin’ in each other’s way”
17:15 I think you have a conflict with your traffic lights. when the bottom row is trying to turn left. There are cars coming from the right that want to take the road down. So it interrupts the flow.
For the first intersection: Are you sure you need that many overpass pieces? Couldn't that be solved more efficiently next to where the car overpass is?
For the big roundabout at the entrance of the city: Why is the left-turning traffic not using the overpass?
I was gonna ask that second question also
If they take the overpass, they are forced to turn left into the residential area at the next junction.
I was going to say the exact same thing! There is an overpass not being used and Biffa doing what he says to not do in his city fixes, and using the Hugo There connectors on a roundabout. It's just making things harder for himself! ＼（〇_ｏ）／
@@edmondleehongpui connect paths on both sides, so they can use both the overpass and underpass to cross over.
They seem to be using the overpass but very rarely. And yes, that should be worth looking into. Maybe it has something to do with the t-junction in the industrial zone that's very close?
But ultimately he should probably rip the thing out and place a real intersection.
24:35 The truck thats supposed to be the first one to follow the traffic pattern properly ends up going around the roundabout 3 times before taking what would have been a right turn. Cracked me up.
Good stuff, as always. Britains NO.1 Traffic manager. Should get out there and do it for real.
I'm not sure there's enough space in the UK for all of the dedicated turning lanes we need :P
@@lordrork5884 Rip out all the buildings older than America itself, then you'd have space for dedicated lanes and better public transport 🤣
Heya Biffa! I always love your traffic fixes and improvements. ^ ^
Speaking of improvements:
22:00 you might wanna try two left turn lanes instead here. All right hand turns from the other side are using the overpass so they don't get in the way
25:00 a lot of cars are using the roundabout to get into the city. But why aren't they using the overpass for that?! That's why you've build that thing in the first place!
0:06 Nope, thats not you, thats how the traffic lights are build in the US. There the traffic lights for your side are on the OTHER side of the intersection.
(just me tabbing back in at 28:35 after swapping windows for a second and dribble-leaking my mouthful of tea in laughter at the extremely communicative graphic design work being done here)
Oh “Fix MY City” is back! Love this series!
Another great episode of Biffa's traffic management magic! I love seeing how all the lanes on asymmetrical junctions are being used. Good stuff and thank you very much! 👏👏👏
About the traficlight arround 17:35 . That is the american way to put the light. They put it straight across the junktion so you do not have to put your head in a weard potition to see the light on top of you if your the first on the light. So to give them the chance to see the light you need to put up the pedestrianbridge. If not they cant see the light.
I love the light teal car at 22:12 just casually driving through buildings to just suddenly turn on a dime and park
Suggestion for intersection at 22:00 mark: the 2 right lanes going straight ahead don't need a traffic light to stop their movement because there's no interference from vehicles turning left as you have the two upper bypass lanes. That should keep things flowing constantly as well 😉. Love the content btw!
@ 37:16 - believe you still have a lane restriction in place that prevents the left-hand bottom lane from taking their first exit to the deadend on this roundabout.
You may also want to extend the lengths of the 4 lane segments for the 2 to 3 to 4 lane transitions so they hold more vehicles that want to go straight at the intersections that were changed first.
This!
I really love YUMBL’s videos. So glad you mentioned about him. That’s so inspiring to me.
I might be wrong but this seems to be the first Fix you created more Traffic than before the Fix 😂 *edit* ok its better. But just so you wait, you did things wich will tuck you up in the long term =P
15:20 as far as i can tell no Pedestrians have been crossing at these Junctions as you missed to setup the Trafficlights for them. Also, going from 2 Lanes to 4 you (HUGO) use one Lane to serve 3 and one Lane to serve one Lane hence they block each other. Sry but some Guy on UA-cam talks lots and lots of Trafficfixing so my Brain is stuffed with this =D
Hi Biffa. At 36:19, I can see that nobody is exiting the new highway connection at that junction, they all keep going straight into the problem one further down the road. Might want to do some "quick (lane) maffs" there. Otherwise a great video. Love your traffic fixers 😊
I saw that, and got a quick glimpse of what looks like both exit roads turning right, at 37:06
24:36 "there we go, this lorry is going into the city"
Lorry: goes around the roundabout twice then exits city.
17:35 the reason why this is, is because you have a designation for left turning lanes where there is no road. When you spun around and zoomed in, they say "Left Turn Signal", but you have no lanes to make a left turn into. At 9:27, you turn on the Left Turn traffic light, but there is on road to turn left into. This is what's causing the Left Turn sign and traffic light facing the wrong direction. You could change the road to remove the 2 left turn lanes if you don't plan on having people be able to make left turns there at all. You're usually REALLY good at that. Every now and then, an intersection sneaks in like that.
Got me screaming the whole episode. When you mention that you added the traffic manager direction so that you don't force anyone but instead the outermost line has been forced to stay in its line.
I've been playing the same map for about 2 months. With a population of about 135,000, that incoming roundabout was always a problem. I finally replaced it with the 'Highwayend Crossing into 6-Lanes - Perfect traffic flow' junction from Predator's workshop. You might want to look at it.
Dale, Can u share the name of this map? It looks amazing
@@_garyumeoi8278 It's called River Maze and is by Sidai.
@@dalearends4216 Thank you!!
at 23:10 why are they not using the elevated part to turn through the city ? there should be nobody using the roundabout to turn left
Biffa, when your in Node Controller, there is a option in there called "SHIFT" to adjust the road intersection left or right. Match the colors to the intersection you want to shift, and adjustment the numbers up or down to move the road left or right. Keep it simple! Clicking it the original way!
When you add asymmetric roads for right-turns, you have the lane management set up incorrectly. You bottleneck the through-traffic to a single lane. The right land should split into two instead of the left when going from two lanes to three for a right-turn.
I don’t know what state this is supposed to be but it’s definitely not mine, you have well maintained roads with more than 2 lanes, sidewalks that actually exist, and public transport.
Tea: check.
Some milk and a little sugar: check.
Headphones: check.
And, of course, no Saturday is complete without a video by Biffa.
Cheers!
When asymmetrical roads don't line up correctly when reversed you don't have to delete and redraw, you can use Node Controller and change the affected node from "middle" to "bend" and it should fix itself. Great video by the way, I always look forward to new videos from you. :)
I was wondering if that was due to the node having been monkeyed with previously in node controller.
The music with the Timelapse of you making the trumpet interchange was such a pleasant moment.
24:44 The second truck that comes into the intersection goes around the roundabout 3 times! 😂 Comes from the inside lane, doesn't slow down, does 3 laps around the roundabout, gets into the outside lane and onto the highway out the city.
I'm so glad you've used YUMBL's ideas. He's really good at this part. 👍👍⭐⭐
Biffa fixes traffic, Yumbl creates roads and intersections, City planner plays makes perfect zonings, T4RGET and Imperatur design interesting landmarks. With their powers combines they'll make one hell of a city
24:38 the driver of the truck you pointed out went through the roundabout twice before figuring out where he wanted to go 😂
Pedestrian bridges at the quadrant interchange might have been almost eliminated by use of the path connections in the bridged section.
Also, overpass + roundabout - really set up badly, and you've done even worse. People already noticed, you don't have people going through overpass, and you went further to force them to go the SAME way.
Also, you restricted them from turning right, they will have to go all around for that, and that will give a bit of useless traffic to your roundabout.
So, anyway, you were true you've done uber traffic management, and you still missed simple things. By the way, in my practice, you could do with so much less lane restrictions with VOP, because in the sections B,C you could remove it.
And the last thing, I'd rather lowered down the lane count on the trumpet, because people will already slow down to go around, they could merge to one lane each way easily. And you could easily live with 2x2 hwy from there to the city, not 3x3, and it would be easy split with all the best lane maths there.
Did you see the truck driving around twice at the roundabout while Biffa tells he goes into the city at 24:35? The truck then leaves in another direction. That was funny!
I just caugh something!
24:37 "This lorry going out the city" if you keep your eyes on it...
Take the Left lane (getting out of the East junction, being at 9 o'clock for us in the video)
go to the middle lane on the West Junction (3 o'clock), stay in lane South, East and North again.
Switch to the outter lane on the West Junction, Go around S - E - N...
Exit to the West Junction to get to the Highway!
What a journey!
(Probably caused by the change with traffic manager)
But it was really funny that you point out the only car that totally freak out and do the round about twice! xD
And also, I would suppose that the speed on the roundabout is higher then the Vanilla Overpass road because most of cars go on the roundabout instead of using your overpass that is made exactly for that reason! (I am still at 25:03 and I hope you fix it later on!)
Also just noticed that the Vanilla Overpass is forcing the cars to turn at the next junction. could be the problem!
Hi ...
23:16 These routes show the error - the overpass is almost unused while a vast majority of the traffic examined is going to the 3rd exit / travelling 270° / turning left.
Is the speed limit on the overpass higher?
Can the overpass be reached from all directions on the left of the screen? Can traffic from the overpass freely choose whether to go straight on or turn left at the T-junction at/above the top of the screen?
24:05 Maybe traffic from left of the screen should be forced to take the first or second exit of the roundabout and be unable to reach the lime green lane connector.
24:27 The side street has two lanes entering the junction (right turn, left turn) - maybe it should have three instead, splitting the left turn into left/overpass and left/roundabout. The lanes are not only dedicated for the directions this T-junction offers but already for the overpass/roundabout split that happens afterwards - this remedies the lane connector issue you mention at this timecode.
A similar "pre-dedication" could be done for the traffic coming from the left of the screen going straight through the T-junction.
23:20 back to the overview - it is a little bit sad you are not zooming out further. It looks as if ~95% of traffic is going straight through to your new quadruple junction. If this number is lower when zooming out, you could try to offer vehicles alternatives to joining the ex-stroad.
35:47 These routes look like a great success - but you do not follow the routes ... 37:11 The vehicles should get off the highway here and take the bridge across the river to the city. I have the impression they don't and still use the overcrowded roundabout instead.
Also 37:11 - the left turning lane from Fawn District to the bridge looks unused (unreachable?) - check lane connectors at the node (top left of screen) where the two two-lane-one-ways merge into the 3+2 road. I think there was a issue with the Ctrl-S shortcut for lane connectors producing strange results weeks ago.
4:43 I think you should make the slope for the bridge over the other road a little less steep, it looks quite weird in my opinion.
18:47 Biffa check your light sequence, you have traffic turning left across oncoming traffic with both lights green. The traffic will work more like you thought if they don't cause each other to brake
I do realise that you may have fixed this in the last 8 months 😂
7:02 I think you don't need the time traffic light at the crossroads on the far right. Before the rebuilding there wasn't enough space between this crossing and the big one, but the big one doesn't exist anymore. I think a give way sign should be better here
7:40 Is that enough space for those turning left? If many people want to drive straight on here, they block the way for those turning left, either they have to get into the right lane at the last intersection (i.e. one lane for the left and one for straight on) or enough space to change lanes here
24:37 You're forcing cars into the roundabout, they can't turn right immediately. And please look at the truck that enters the roundabout from the left on the left lane here, it goes completely around the roundabout twice before exiting it. Maybe it's just confused by the changes, but better double check. And I think you should increase the speed from the bridge, if people want to go into the town they should use that bridge and not the roundabout or do they have some other reason not to use it?
25:16 shouldn't they be using the overpass to get into the city? They shouldn't be turning left through the roundabout
That unused 4th exit from the main roundabout is just begging to be creatively hooked up to the highway. I'm loving these link roads with the little tunnels and custom intersections though, very cool and you get to work with the land so much better than just flattening everything to try to fit in a stock intersection. Nice work!
Having 2 interchanges from the same highway right next to eachother connecting to the same roundabout separately just creates a lot of unnecssary crossover. You generally want to give people options to do DIFFERENT things. otherwise you're just adding tarmac and complications. That road should be reserved for future expansion.
Although splitting his current highway interchange into 2 roundabouts connected by that road could be a good thing. It's how most modern european interchanges are built now.
@@heygek2769 He could reconfigure it so the existing connection is inbound traffic only and the currently unused is outbound only, or have each connection service one side of the highway. There's so much traffic funnelling through that one connection with a completely disused highway-sized spur right there. But yes you're right, redundancy for the sake of it is generally not a great idea.
11:30 - your lights are misconfigured. You can see left turn traffic crossing while straight through is crossing from the other direction on both sides of this interchange.
Having picked up the game again for the first time in a number of years I must say your AA solution is impressive. I'll be taking a look at your mods/order!
26:40 Biffa! Just make that nothern intersection only go straight on, no left hand turns. That intersection's left hand tunrns are forcing the bypass traffic to take a left there, which basically none will ever need because they have an intersection right before the roundabout they are more likely to use.
Traffic from the highway can either go straight through the roundabout and make the next right, or use the second intersection to the north to make a left into the city. Same with traffic coming from the south, which doesn't actually exist yet. And because all the roundabout's traffic from the west will have a bypass that lets them go left, the conflict on the roundabout will be significantly reduced for the other directions even with that northern intersection disallowing left hand turns.
Also, if traffic is still a problem even after this change, I would suggest a traffic circle (lighted roundabout) before entirely replacing it. Easier to do and it may just work.
This is way smoother then my city I'm definitely taking notes and I like the hanging traffic lights. I have the NYC style lights in my city
20:45 The lanes are wrong. The left lane should only be for the left straight lane, the right lane should split into straight and right turn. You won't get the people blocking the lanes on the left side this way.
I'm going to keep banging on about using node controller on roundabout entries until Biffa finally listens to me! Cars are really slow getting onto your big roundabouts because they're so far from the entry!
Node controls: use shift to line up intersection, then select middle node (which will only have one dot), shift to select, and then select dot from previous node. I'm sure I've seen Biffa do it dozens of times, he was just juggling a lot of thoughts 🙂
The truck at 24:36 where you say it's going into the city actually does 3 rounds in the roundabout and leaves the city. hahaha
At 17:33, the traffic lights are not facing the wrong way. In the US, especially with overhead lights, the lights are placed on the far side of the intersection so you can look straight at them. Otherwise, the light would be directly above the first car in line and they wouldn’t be able to see it.
What an interesting solution / alternative to the 4-way intersection!
You really have made a monster of a traffic problem in this city LOL! So much traffic fixing and playing around!
And I'm loving it 🤣
You would probably like Workers and Resources: Soviet Republic. They're coming out with a garbage update and metro systems soon. It is really, really cool.
The new interchange you built is weird because it goes from a highway down to an arterial and then right into the interchange. A system interchange like a trumpet would make more sense and remove the need for a traffic light there
Glad I'm not the only one who decide a direction is "north" and then repeatedly orientates to that.
16:10 Never a dull moment for Traffic Cops! 😂
25:00 Why aren't they using the bridge to go into the city?
Why not reverse the overpass at the main traffic circle. Turning right is only 1 exit on the circle but the people backing up to go left have to go around the entire circle. If you switch them it should be fixed.
Or make the lane at the end go straight, not just a left turn
I was going to comment on the overpass east to north not being used (on the main incomer roundabout) due to issues north of it, and people seem to have discovered the next intersection forcing that route to go left only.
That is what's causing a lot of the traffic on that roundabout being so busy!
Good luck fixing that.
Thank you for the help lads for resolving an issue I had with my game.
Keep up the great work Biffa, your community is amazing
There is a setting in TMPE that allows buses to ignore turning arrows - have you tried turning that off?
Two things could be going on here. It sounds like they can't get into the 'right' lane and yet still want to follow their route.
1. the busses could be forced into that lane (something with lane restrictions or dedicated bus lanes?)
2. the busses can't get into the lane they should be in because of Hugo There, disallowed lane switching
Do you use any mods that influence traffic and/or mass transit?
@@lordrork5884 thank you I haven't played for 3 months or some and I knew there were updates but I have not seen this feature. I unchecked it, thank you once again for helping. I'll change the comment
@@heygek2769 thank you for trying problem solving with me appreciate your thinking and time, it has been resolved
24:37 That white lorry went around twice only to decide to leave anyway hahaha
24:36 that first 1 Goes around and around and want's to leave the city but Biffa does think he wants to go into the city Hilarius XD
At at 23:11 Is the over pass a 1 way or 2 way because it looks like the cars aren't using it (to go into city from industrial)
also the truck just went around maybe 3 times
in the US traffic lights for a lane are actually typically across the intersection to make them more visible!
21:51 you did well, "enlarge" is a dangerous word on the internet
2:40 - Biffa, set your timed traffic lights up with :
Min : 1
Max: 10 (change to how long you want green)
Type: No one is driving
Sensitivity : medium
You will find traffic will flow more freely, especially when no on is driving, the lights cycle quickly, but allow banked up traffic clear. The max time allows for more throughput than waiting.
the lights setup depends on a myriad of factors, like the road's purpose (arterial, collector, local, ect), traffic volume, ect. the way the lights run here (in the great lakes region, at least) is rather long green/red cycles, between 15 and 30 seconds (25 is common at highway junctions).
what you have listed is something i would most likely use at two collectors crossing one another, unlike the Quadrant Interchange like what Biffa has set up in his video.
I think running a highway where the busy road is at might be a good solution. That's really common in us and although it might not be the best looking, it does work👍
Your Lane Mathematics is slightly off in one crucial place. at 15:31 for instance, whenever you have 2 lanes approaching the intersection, with the turn on the right, you are forcing both lanes that want to go straight, to merge into one lane, then they can spread out to two again before the intersection. In that clip, on the left, the blue connection needs to be dedicated, and the pink one needs to split into two. And on the right, the green needs to be dedicated, and the blue splits into two. The red could split into going straight or turn lane for max flexibility. This would also need to be done coming from the "North" on the other road.
Yay fix it video!
For the roundabout, maybe could use 3 lanes in the roundabout. I think I e heard you say in old fix it videos to always have 1 more lane in the circle than the roads feeding into it.
Take a look at New Jersey jug handles! I use them in my cities and they work like magic. Instead building an overpass I’d keep the 4-way intersection and restrict traffic to only go straight or right. If they want to turn left they have to use the “jug handle”
on your new three-way junctions, i think you have the traffic lights restricting the flow of lanes that it doesn't need to restrict. For example, traffic coming from the west, and turning south, will never need to wait. At each set of traffic lights, it crosses no lanes (essentially, it could be a dedicated lane and not interact with the lights at all).
I would try dedicating a single lane for right-hand turns, and have the *other* lane for traffic that the lights controls. Same for straight on, on the north-south road, and the east-west road. It seems like it would flow without interrupting most of the traffic.
EDIT: that section at 23:10 where you check where everyone is going, and then amend the lane management to accommodate the volume of traffic going into the city... The overpass that is bypassing the roundabout SHOULD be taking all that traffic. only traffic that is leaving the city or taking the other (as yet unused) junction should be going to the roundabout.
EDIT2: The above edit means that the traffic entering the city from the highway should have an uninterrupted entry onto the roundabout, as there'll be nothing approaching from their left to stop them (at least until that unused section becomes used).
Hey Biffa. You could use pedestrian tunnels instead of bridges so the cars can see the traffic lights again 😉
Just FYI - you've set up the quadrant interchange timed traffic lights incorrectly. You've got left-turning traffic and straight-on traffic going at the same time, which shouldn't happen. You NEARLY copied Yumbl's setup, but got one of the phases wrong.
You'll probably need to look too at the interchange bringing traffic from the northernmost highway down through your industry area - that little off-ramp etc. leads into a major 4-way interchange, which the traffic doesn't seem to like using much - so your trucks are still going via the fastest route down through the same roundabout they were using in the first place. You didn't really have time to get to that though, so I'm hoping you will!
Love the content, as always!
24:37 watch the white truck on that left lane going into the round about and going around it like three times... Before finally taking his exit lmao..
That log truck that came from the left thit 2 hole Laps at 24:43
Nice to see some traffic decompression being used - double the lanes halve the pressure.
The space between your new trumpet interchange and the border of the new square would be a great place to fill your industrial need and place something like the giant trash burner - far from other uses that hate the pollution, but not that far from the city and great road access
19:00 "That is working fine!" - It really feels like it's just not: Your queues are still super long and if anything you will end up adding more traffic in the future: 10 bucks says you'll have to come back here again in the future and to a partial cloverleaf or an actual full interchange later anyways.
With these junctions you can always give each right-most lane the ability to always go through (permanent green light) by giving them a lane only they can go into.
What i mean is the topmost lane of the T and both right inside turns. They do need their very own lane coming out of the junction. But it's a great bypoass where needed.
it’s honestly lore accurate that the sidewalks don’t properly merge with American roads
That main roundabout at the entrance to the city needs to be upgraded to a turbo roundabout. Should help the traffic as it is now, essentially giving each direction its own lane. But when yiu start using that other road, you'll really want a parclo in there. Yumbl is just fantastic, he really knows his stuff
You built basically what we call in New Jersey- a Jughandle. It is a handle to a jug- or like a milk gallon. We have them everywhere.
The partial interchange is quite common in the older, denser parts of the US, like New Jersey, Philly, B'more and DC areas. It is "easy" to upgrade an intersection to a much higher traffic throughput with the single diamond leg and is a smaller amount of land "taken".
There are many on little two lane roads too.
For your new highway interchange, consider realigning the existing highway entering from the northeast (I think??) straight into the new highway. That would seem to be the dominant movement.
Traffic on the existing highway coming into town from the opposite direction already has a route into the city, so this could be simplified with a fly-over ramp for any through traffic on the existing highway.
I don't know that you'd need a full system interchange here, unless you want it for symmetry's sake.
24:37 that first lorry is definitely NOT going in to the city 🤣 it went on a rollercoaster ride
28:06 the trucks leaving the unique factory area are still being forced to turn right because you made a mistake with dedicated lanes. That’s clogging up the original highway junction more than it needs to.
I’m sure it’s been said but in America, we have ‘right on red’. So anyone turning right at an intersection with a traffic light can treat it like a yield. That means 3-way / T junctions flow much smoother.
Aldo, your overpass on your entry roundabout isn’t being used from the industry into the city. My guess is the lanes from the intersection are the cause.
