Professional Highway Engineer plays GridRoad! 

Matt building the squareabout anti clockwise (ie wrong) moments after boasting about how we drive on the correct side of the road is peak RCE.

RCE: Says Left side is the correct way. Also RCE: Builds a right sided Squareabout.

Did Matt just create a right-sided roundabout in left-sided traffic game?

It's impressive to pass the last mission in such a way. Its like cutting a steak with a fork while holding the steak in place with the knife.

Did... did mr. "I was a highway engineer" just put the roundabout the wrong direction... after talking about the game being left sided? Dear Mr. Matt, you just proved the point of the rest of the world, right side is the right side. xD

You are a UK person, driving on the left… go the correct way round the roundabout… left, and it’ll be easy to pull off the exits as they pass, rather than cutting each other up at the four corners 16:10

It feels like RCE is trolling us with that square-about design. 😂

Matt's not a secret Architect, he's a secret American

17:09 flip the rotation. Make the cars go clockwise around the roundabout.

Matt seriously forgot which way a roundabout was supposed to go…

Ooh, Freeways vibes from this. That series was an absolute treat, this should be awesome.

Bro your roundabout was BACKWARDS XD Such an architect move.

I've always wondered how the sensors in the road worked and you gave a simple explanation. You're the best

Matt gonna be so embarrassed when he sees the comment section is calling out his attempt on squareabout😂

Do you need to put the traffic lights at the crossings? If you move the arrows and traffic lights one square earlier, that would give you even more fine tuning in the timings and prevent the cars crashing as they take time to accelerate.

Matt using his engineering skills to make traffic lights pass faster is the funniest thing 😂😂😂

Just me or did Matt pull an architect move on the first level? Those cars needed-nay, deserved-a dedicated left turn lane

RCE : "Driving on the left lane is the correct way" Me living in asia : *nods RCE proceeds to make an counter clockwise roundabout. Me : YOU WERE SUPPOSED TO BE THE CHOSEN ONE.

Aside from the American square about, I'm pretty sure for the 2nd puzzle you just needed to move the eastbound lanes' traffic lights back a tile. The time it takes the cars to accelerate would be plenty for northbond stragglers to cross through. You had the light sequence perfect though

Separate lanes, make it turbo squareabout. You have a lot of space. Meaning a car going right, a car going straight and a car going left would each use different lane, with the left car starting close to the center of the squareabout and gradually switching lanes until leaving. Or the right car, if you switch to clockwise movement.

As a french guy I find it realy fun to see a english engeneer trying to rework the round about so the roundabout. Witch, btw, is the best type of intersection because it is safest and it provide a continues flow of trafic thanks to the fact that the incoming flow never crosse the outcomming flow

Matt giving us pro-tips on how to minimize waiting on a red light.

freeways was when i first watched your channel and i absolutely loved it. Therefore anything similar is always appreciated, even though i know, it probably doesn’t bring the clicks, other videos do.

I believe traffic lights now use cameras with computer vision to count the cars, cheaper than the road sensors and you can actually buy and install your own system

Honestly love videos where we get to see RCE's genuine expertise.

When Matt said Red Car and Blue Car, i instantly had the Milky Way [UK candy bar] advert from the early '90s pop in my head - "The Red car and the Blue car had a race, all Red wants to do is stuff his face, he eats everything he sees, from trucks to prickly trees, but good old Blue, He took the milky way" lol

For the squareabout, try making your cars go the other way around, so its the right direction for left hand driving - American who plays Cities Skylines

In the US we don’t usually use Loop Detection anymore. Too much maintenance and cars are increasingly non-magnetic, so they don’t trigger the sensor. Either Radar or Video are used.

Damn, I now know 2 cheat codes. 1) Elevators have a certain combination of buttons for movement that skips all "awaiting floors" and goes right to the selected one. 2) Traffic lights have underground sensors(?).

I bet BIFFA would be an absolute MASTER at this game !

I think that if you turn the squareabout in the other direction, the cars will be able to exit more easily and therefore clear the ground for the following cars.

@7:30 about the traffic light sensors. I've witnessed many people pull past the white line mark so they're past the sensor and the light just stays red for them for 2 minutes or more until the auto-timer kicks in. The irony of it makes me chuckle every time; they pulled ahead in the lane to 'get ahead' but are time-locked by the traffic light. Unless I'm behind them then I trigger the sensor if I can.

You should use a two lane roundabout where the inner lane is for driving full loop and outer lane is for turning off only. Meaning you would have a left turn at the corner on the inner lane and a right hand turn (hopefully works for switching lanes) in the middle on the inner lane. Then obviously you would want a right hand turn again at the corner of the outer lane to exit the roundabout.

The answer is counterflow. Build your backwards roundabout but put in turning lanes going the opposite way on the outside so cars can turn off before the light and bypass the square completely if it's the right color.

You absolute architect! Roundabouts don’t go that way around. You made everyone cross the traffic flow to get off the roundabout!

In the US our traffic lights have a camera that use infrared to sense flashing lights, so they'll turn green for emergency vehicles. Super illegal but if you get a flashlight and get the timing right, you can flash a flashlight at the light and it will think you're an ambulance and turn green for you

Just scored over 7500 on teh 1st level, 1st try, no traffic lights!!! Gave the yellow cars a lane across the top, used slip lanes and left turn lane and everything just flowed. Love it! Just regret I didnt record it.

He's either an engineer who has decided to build a backwards round-about inorder to maximize his engagment or he's an architect who forgot how roundabouts work.

when Matt was trying to work out timings, all i could hear was "At 12 o'clock, ill have fish...and a rice cake, at 2 o'clock ill have me fish" 😂

a roundabout is just like a motorway: first the roadster that leave, then the road that joins. I have learnt this from you, and now you do it just wrong. didn’t expect this.

For the squareabouts, regardless of the rotation being the other way around, adding an extra arm would reduce the traffic going around the squareabout by a fourth since they just need a U turn for their flag.

i decided to google it, the cost is surprisingly accurate lmao. assuming the lanes are 2m wide (bit wider probably maybe 3m), with asphalt costing 125-250$per m2, each tile should indeed cost around 1k

The sensors in the roads usually don't control the traffic lights, they're just used by the city to measure how the traffic is and see if the light needs to be adjusted.

You should try taking the entering lanes and moving them around the border of the grid around to the next exit lane and just have stop lights there as well, itll combine the efforts of your 2 Lane square-about, and the one lane traffic light method. It'll reduce congestion in the center circle and provide multiple other lights for them to disperse where they aren't even near the center roundabout if they don't need to be

Squareabout proving RCE is actually a true Architect.

Hi, real life traffic engineer here. 7:35 is entirely wrong. The one "square" set further back from the rest does NOT cause the light to change faster or anything like that. It is an "advance detector" that catches traffic moving towards a green light and adds a few seconds of green to allow that car to make it through the light (up to a cap of course). E.g. if the signal goes green for an initial 10 seconds, and at 8 seconds a car drives over the advance detector, it'll add 3 seconds to extend to 11 seconds. Then at 10 seconds, another car drives over and so now it goes to 13 seconds. Repeat until you either hit the cap (say 30 seconds) or the signal "gaps out" by having more than 3 seconds between cars going over the advance detector. The signal then goes to yellow and moves on to the next phase. So stopping on the advance detector at a red light does literally NOTHING but potentially causes gridlock by forcing people behind you to back into upstream intersections. So don't do it. Please.

On the simplic-T level, the top lane going left to right can be green while the right stoplight is green. No cars from that stop light can turn left so they will never impead the top lane.

The squareabout showed architecture at it's finest. You might need to change your title to RCA. I can't wait for the second video in this series!!

I found that making bigger traffic squares was helpful, as well as allowing shortcuts where possible.

Something Matt seems to have missed with the Squareabout is that some cars are leaving from the same direction they arrived, which means the traffic in the squareabout could be alleviated further by providing an early point for u-turns. Pay attention, mr. "I was a highway engineer".

him making the roundabout the wrong way is so funny, truly was an American round about

Drawing a round about the wrong way is a true architect move, Matt needs to meditate to recharge his engineering energies

You just made a normal anticlockwise roundabout for cars that drive on the wrong side of the road. Architect level of engineering mate!

That roundabout level was absolutely painful to watch 🤣

i have two suggestion on how to improve that square roundabout. 1. i noticed that some cars are of the same color as the outgoing side of their arm, so letting them U-turn should help a little. you may need to adjust the road layout a bit to make that easier. 2. you could split the arms of wider, there is no need to make the roundabout as tight as possible. that would allow more cars to be in transit and therefore allows for slightly longer signal times and that should improve your score. i also have similar advice for the level before 'priorities', if you want to further improve your score. if you split of the double roads and let them run lower and higher so that they are one signal time apart, you can get the cars to no longer crash. ...or alternatively you could just place the signals a block further left, to give the cars a field delay, needed to let the bottom cars leave the road.

See in my town they've got no clue how to smooth the roads for a lane, but the guys are RELENTLESSLY trained on how to hide the traffic sensors so you can't trick lights. Priorities indeed

I love the shade dropped at the end there

"See how we are driving on the left? The proper British way." ... Then proceeds to make a counterclockwise roundabout instead of the British clockwise roundabout.... lol as an American I approve 😂

Hopefully Matt gets the squareabout "right" when he returns to this game. 🙂

11:00 That's what we call a Green Wave... Works great for arterials and circulars😄

Pretty sure you were building the squareabout in the wrong direction. It should go clockwise

15:00 - HOW DID YOU GET THE DIRECTION OF TRAVEL ON A ROUNDABOUT WRONG?!?!?!?!? Bloody Architect

I have strong feeling, that you made the roundabout the wrong way (cars should go the other way around). First and for most: this way, when you go, you first encounter entrance, and then exit. And second: I'm almost sure that's, how we on the continent ride around roundabouts. Hope I helped ;)

Omg this is like another freeways game, that series was my favourite I’m so excited there’s more

For the squareabout, do oppoosites moving at the same time with all red for 1 tick to allow traffic to clear

As a Brit, I very much appreciate that drivers drive on the correct side of the road in this game.

I can't believe Matt forgot how roundabouts work. I'm an American, I don't like them, and I don't like driving them, but even still I know how they work, how to properly drive through them, and I definitely know how to use them in video games.

The Dev probably didn't use an anticlockwise roundabout in this left side driving-based game.

Maybe Matt needs to come over here to New England (the best England) to see all the American roundabouts that go the proper way and work better? Cause, yes we do have them and some of us know how to drive on them.

Amazing how Matt claims to be an expert in terms of Roads and stuff, yet build the Roundabout the wrong direction and therefore always crossing eachothers paths XD What he did is basically what you would do with righthand traffic. Amusing XD

The thing that makes these kind of games so puzzling is the human factor. On the first level in the real world you could have the lights on the top of the T be on the same phase and people would just yield when having to turn across it. And on the 2nd level (the parallel one) you almost have to have a delay between phases where there is no green lights so traffic can clear the intersection. That's something I actually notice here in the States where there is a bit of a delay between phase changes after one turns red.

On the priorities one, you could have set the traffic lights further back so that the cars stopped 1 block earlier, giving the junction time to clear from the cars travelling north.

Oh Mathew, I'm not upset, just disappointed. It was from your videos on junctions that I learnt that cars should leave the roundabout before joining. The last few minutes of this video were PAINFUL to watch 😂

You made England look like a load of architects 😂 square about what you doing

7:56 Matt going to traffic jail for this one boys, we finally gottem 🤝🏼

Fun fact: traffic lights are only slightly more complicated than christmas tree lights. Source: Former electronics engineering student. No job so not a legitimate engineer.

This game once again proved that he is an Achietect instead of an engineer...

you should also have the possibility to do U-Turns on the Roundabout. Since each side spawns cars that want to got the same road back.

The best thing about him creating the reverse roundabout is that they really exist, I’ve driven them, they’re absolutely terrifying and dangerous, due to being contraindicative. As we all know, they were designed by a dark and terrible version of architects… city planners!

I can't even. You made the roundabout go the wrong direction. Right after you explained about British driving being better, you made the roundabout go the American Counter-Clockwise direction.

Square-roundabout: some cars don't need to enter the round about. if there car colour at input matches the output colour at input, then a right hand turn is all that is needed I think. (hopefully that makes sense) Like a U turn basically. That should decrease congestion🤞

I think the solution for the squareabout Level is a magic roundabout. It looks very messy but it helps to spread the traffic a bit more out.

I saw the other comments saying the proper counter clockwise flow of traffic on a rotary... for American roads... Thumbs up from the US Matt!

Building a roundabout that goes counter clockwise is what I expect from an architect Mat… oh how you’ve let us engineers down

For the roundabout you can use two lanes. Smart roundabouts in my country force you into the lane you need to follow

1:18 🎶🎶The Red car and the Blue car had a race, all Red wants to do is stuff his face, he eats everything he sees from trucks to prickly trees 🎶🎶 Who remembers?

Wow, he discovered the green wave. If he didn't intuitively come to it when seeing the second junction, I'm not surprised about our daily traffic.

Where I am (British Columbia, Canada) we have the traffic sensor right before the stop line, so that any traffic stopped at the light will trip the sensor. Not sure if that's more or less efficient than having the sensor further back... but based on how the experiments in the first level of this game worked, I'd say it's more efficient to have the light changing more often.

Omg! I love the DinoPoloClub burn at the end 😂😂

It’s Engineering TIME!!!

Out in Houston, Texas, they don't believe in having sensors on the light systems. The majority of lights have a single timer for the entire day... not even variable based on rush hour as well.

12:58 solution just move the left traffic lights back a square or 2. gives the cars coming from the bottom a extra second to get out of the way.

you know it's a good day when matt uploads and put asmile on our faces. Keep it up man

I almost cried looking at that roundabout goingnin the wrong direction.

Squarr about...Larger square on the outside. On the T interchange, split for a through lane on the top, as well as split right turns a couple cars back to minimize how far backed up

This feels like 90% the kinda game I’ve been looking for - something like the traffic manager mod in cities skylines where you can manage traffic on a lane by lane basis, with the traffic lights etc. Can’t wait to see how this game develops in the future and also if anyone has any suggestions pls let me know, I’ve not had any luck in my search

I like this game, unlike how Matt drew the roundabout the wrong way and didn’t even put slip lanes in

I live in a relatively small capital in Brazil, and the drivers are terrible. The pinnacle of traffic inability around here is seeing that they put traffic lights at a couple of roundabouts, like... normal roundabouts lol

I appreciate the visuals for the sensors editor

16:39 seems like the roundabout is also going the wrong way for left side driving. Should be clockwise.
