@@compdude551 Kinda, they put an alternating current through it. When there's only air above it the current changes easily, when you park a lump of iron on top of it it becomes hard to change as it's trying to magnetise your car (kinda) they pick up how easy it is to change the current flowing through the coil they put into the road.

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.

The dutch way works like that, among others specifically allowing to have green lights on intersecting paths at the same time Which allows for much faster cycling and with that less irritation Which is an important margin which the Americans don't even see

[@jankoodziej877]

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.

[@kratix0469]

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.

[@bookworm5523]

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.

[@danyael777]

I think we use pressure sensors in Germany not sure though.

[@Diarmuid056]

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.

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

[@SovaKlr]

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.

[@Irathecool27]

The math behind the traffic lights is fascinating. Love that rotation and subdivision are the primary drivers of score. Partitioning ftw ig?

[@Narcle0]

@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.

[@johnnycruiser2846]

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

[@o_s-24]

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

[@cainhager9814]

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

[@maximilianmorse9697]

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.

[@jankoodziej877]

This is not true. In many intersections they are used to dynamically change the phases. In fact, in some of them, one road could always be red unless it detects a car.

[@scartekgaming]

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

[@danser_theplayer01]

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(?).

[@Girraficusthewise]

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

[@happyhafer1403]

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.

[@aydendejong451]

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.

[@ThorbenBuschMusicOfficial]

That roundabout level was absolutely painful to watch 🤣

[@knusperhexe]

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.

[@OneEyedOneHornedGian]

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

[@savijdafuq6776]

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.

[@nicomurphy5206]

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

[@CoffeeFresh_]

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.

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".

[@TEAM-ev9xt]

Good man RCE i live in the UK as well

[@jacksonstarky8288]

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.

[@danyael777]

Same here in Germany. They're a little skewed in order to cover a longer part of the road.

[@jankoodziej877]

In the example he made, there is also a sensor next to the traffic light. In many intersections one sensor is simply not enough, as it can't tell how long the waiting line is. One sensor is fine only for small roads with low traffic.

[@meforever1997]

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

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.

[@nathnathn]

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.

[@ADBBuild]

On the Priorities level, you just needed to move the horizontal traffic lights back one square. This gives vertical traffic one square of time to exit the intersection before horizontal traffic gets there.

[@alexsch5583]

You could have set the traffic light on the purple road further from the actual junction to alternate the timing further. That might help avoiding crashes while maintaining the best flow.

[@driscey188]

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🤞

Roundabout with lights should have 2 phase light, not 4 phase.

[@Maddyrayray]

I appreciate the visuals for the sensors editor

[@ericbonanno5214]

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.

[@Axeinus]

personally for the second level, I put both purple and yellow in the middle and had 1 crossing intersection. no need to have 2 crossings if 1 is in the budget. beat the dev score pretty easy that way

[@donaldham308]

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

[@xxSeanVxx]

[@Szymmon614]

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 ;)

[@j0hnf_uk]

There needs to be an option to place in junction boxes, so that vehicles can't enter a crossing unless their exit is clear. That'd stop all the colliding that goes on! The squareabout should be made larger to allow more traffic onto it, with 2 separate lanes, one for traffic turning left and another for traffic going straight on. That's how roundabout work, after all. Why you designed in to work in an anti-clockwise direction is a bit puzzling, though.

[@FireNinja7365]

On priorities you can maybe add extra lanes on the vertical roads to get a better score

[@Maindric]

I felt the second main would have been faster if you brought the two bottom pages together in the middle and both go up at the same time at the same spot. This allows you to only need one set of lights for the two cars going right.

[@jankoodziej877]

I thought about that too, but actually not sure if it would change much. What I would try is splitting traffic on each lane into 2 lanes, if that's possible, then you have double the flow through the intersection.

[@IrredeemableGhost]

I bought this game thinking it'd be fun, but it's far too limiting. I spent a while trying to wrestle within its constraints, but when I finally got to a less intended solution the game just crashed. I can't recommend it right now, but RCE sure makes me want to play the games he shows
