A real highway engineer experiments with real four way highway interchange design in Freeways to see if Freeways is realistic in modelling traffic flows on real highway junctions. I love a game made by just a single person, but when it's one about creating the most efficient highway interchange layouts I am 100% sold! As a civil engineer of 10 years specializing in highway design, I should be really good at this right? Right????

About Freeways:

Freeways is a game where you draw freeway interchanges. You are the traffic engineer.
Draw roads like you're drawing a picture.
Design for efficiency or draw the spaghetti junction of your dreams.
Simulate traffic flow through your interchange. Most importantly, avoid traffic jams.
Connect a whole world together in a network of interchanges. Features 80 levels.

    The "windmill" is not the image that came to mind when looking at that.... certainly a strong shape, when not in a Russian winter.
  • 10:19 - "This is called the Windmill Interchange, because it looks like a windmill." Me: "Riiiiiight.... A windmill........."
  • 14:14 fun fact: the magic roundabout in swindon is extremely safe because of how slow traffic moves.
  • @DecayedPony
    All this game needs is an eraser tool, and a smoothing tool.
  • @TheBestPybro
    10:17 Yeah, I can see that one flying over Europe sometime during the 30's and early 40's
  • It seems that the formula for efficiency is 1000 * traffic flow * complexity factor / concreate used. The displayed values are probably rounded down. As for complexity factor, I think it represents the amount of traffic; here, there are 4 entry points that want to go to 3 exits with a weight of 3 (the thickness of the arrow), so 4*3*3=36.
  • @OriginalPiMan
    That complexity rating is for the complexity of the starting conditions, not the complexity of what you build. That's why it was always 36 here.
  • @mattm7220
    The biggest problem with the game is that it doesn't allow for multiple lanes of traffic on a single road. That diverging diamond would have been far more efficient if you could have designated different lanes for different destinations, instead of it all being single lane shared traffic.
  • @MrThijmenmees
    Really cool to see, but I would've loved to see a "Gothic interchange" being tried. It's basically a double diverging diamond, with both highways switching sides. It might work really well here
  • @tdestro9_362
    I love it when you actually use your job in videos I find it extremely entertaining
  • Really love the magic roundabout. Super efficient use of concrete for a moderate tradeoff in efficiency of traffic flow. Handles traffic so well though, especially when drawn with nigh perfect road placement.
  • @earthling_parth
    I am a CS major and currently work full-time in IT. It's a absolute blast watching you play this game. Might buy a copy myself :)
  • @wulfieonline745
    The cool thing about this game is that I believe all of the interchanges you reference here are referenced somewhere further along in the game, with the required traffic flows on each junction referencing it.
  • @MaksB.
    10:16 Thank god that's called a windmill, I seriously looks like a swastika.
  • I'm not even an real engineer, I just like this kind of games, and you too
  • I've been watching some of your videos from yesterday but this made me respect you so much. Subscribed.
