Rules For Ride Design

ASTM guidelines cover things ranging from the design of restraints on rides to the maximum G forces riders can experience. Today we'll be taking a deep dive into the standards set by ASTM and how they affect the rides you enjoy.

Me, playing roller coaster tycoon and thrillville: we have no rules, only ideas

[@ihavenonamemenamejeff4147]

Kinda the same for planet coaster

[@gabriellequary9513]

Wait where can you find thrillville 😭 I miss that game so much

[@sociallyexhausted]

@@gabriellequary9513 I bought it on steam a while back! I was surprised to find it there but when I did I had to get it lol

Definitely need this for planco

[@gunkwizardry]

this video was super informative! I love learning about how coasters and rides work :) only thing is I wish is that there was maybe like a caption or something in the description that says what rollercoasters were shown in the footage but thats just me

[@CoasterCollege]

If you have questions on rides shown at specific time stamps I'd be happy to let you know what's shown.

[@TheRadioAteMyTV]

Thank you for making another science styled video that works in the classroom too.

[@CoasterCollege]

Was actually made as part of a college project lol

[@sheepkind]

i was READY for this video 🤩

[@simpai1585]

Wooo🎉 new video! Who loves roller coaster engineering ⬇️

[@maincoasters]

love it! i want to do it one day!🙂

[@Daniel_Coasters]

I love it!!!! I am those type of people that record the g forces every time I go to a theme park

[@wendyjaa]

This is so super cool! I love the super nerdy coaster stuff!

[@epicpoopgirl1]

love all ur vids ur actually informative!!🩷🩷🩷

[@SharpieEasternn]

Love these sort of explanation videos

[@delightfulari]

So interesting, another brilliant video thanks :)

[@phyllojoe5346]

Cool, I really liked this!

[@sonic23233]

Also, the reason that the US can't have a 600ft Rollercoaster

[@Falcon-_-]

The reason US cant get a 600ft coaster is because it is too expensive, all Intamin coasters (including Falcon's Flight) Follow ASTM guidelines

[@antoineosburn8626]

Video was very interesting.

[@thedude4063]

Really good info for games

[@3clipse_watcher476]

Extra nerdy, but we love to go over the details.

[@intotheunknown804]

This video was great would have liked the video a bit longer more videos like this please

[@dindog22]

so why does a ride get higher G Force limits if a rider is in the prone position? is it easier for our bodies to handle the forces? this is an interesting video. I like the informative stuff even though I don't work in that industry

[@CoasterCollege]

Yes, the body can take the forces better in that position.

[@chrisogrady28]

As vertical G force is only a problem due to your brain. When you're sat down your brain is subjected to high blood pressure during negative G and low blood pressure during positives (thus blackouts). In a flyong position your brain is not at the top of your body, so fkrces would have to be MUCH higher to experience equal symptoms. So for me the confusing part is why it only says 'slightly'. A 6G flying loop would be safer than a 4G sitting loop for example.

[@RideManDave]

This has mostly to do with cardiovascular effects. Because of gravity and the way that our cardiovascular system is designed to operate in a vertical orientation, the body is largely unaffected in the most important ways by accelerations in Y, and particularly in Z. In a prone or supine position, the effect of gravity is moved to another axis, which leaves an allowable increase of at least 1Gz. Remember the acceleration limits are tied to the patron coordinate system.

[@Menoetia]

Semi-related: can you do an episode on the specifics behind why some rides disallow riders with certain health conditions (heart trouble, back trouble) from riding? You've covered amputees in the Man of Steel incident, but I've always wondered why some of the seemingly 'tamer' rides have signs like these. How do parks handle guests with visual or hearing impairments, or other disabilities? Is it up to the guest or the park what someone can ride in those cases?

[@AG7-MTM]

If you wanted a better fast-transition intamin to reference, CoasterStats did a full g-force video on Toutatis at Parc Asterix

[@CoasterCollege]

Well that one doesn't have to comply with ASTM.

[@Koaster-Kritik]

@@CoasterCollegeASTM and DIN 13814 (the European standard) are similar - the ASTM actually allows for more negative forces and is otherwise very close. If a ride is compliant with the DIN standard, it is usually also compliant to the ASTM standard. Technically, there might be differences as the ASTM requires a different sensor position than the DIN does, but that is (at least for the purpose of us enthusiasts) more or less a detail and has little impact to ride design.

[@TS_Mind_Swept]

Not only is that 200 MS time requirement between transitions safer, it just makes the ride feel like it was designed better ((cougharrow)) (Look, I love their rides for what they are and what they did for the industry, but those zero lead-ins are just so jank SuperVinlin )

[@keiyakins]

extra fun, apply these to the wrong thing. Does your bed have at least level 3 restraints? Since you lie down on it, there's zero gees eyes-down, so it should!

[@CoasterCollege]

You sleep face down, eww

[@keiyakins]

@@CoasterCollege Doesn't matter, actually. On your back it's eyes-in, on your stomach it's eyes-out, on your side it's either left or right. In no situation is it towards your feet.

[@coastercult4142]

I hope I can be a roller coaster engineer

[@SnowghostFilms]

Noted

[@patricktho6546]

Do you plan on doing a similar video about the European equivalent? Like EN 13814-1:2019 etc?

[@CoasterCollege]

Possibly, would take a lot more reading lol

[@RideManDave]

…and besides, ASTM and Euronorm work very hard to harmonize their requirements. They are not the same (and standards committee members on both sides sometimes think the other group passed something idiotic) but at least they “rhyme”. Also, ASTM is a little more agile than EN. EN has a publication schedule while ASTM does not; for example, the worldwide design standard, F2291-23b, was actually published three times in 2023. And yes, it is a worldwide standard, used by any designer, manufacturer, operator, or…and here’s the big one…Authority Having Jurisdiction which chooses to adopt it. A big reason for harmonization between ASTM and EN, particularly between F2291 and EN13814 is so that if you build a ride to either standard you will be substantially in compliance with the other.

[@unifiedthrills]

This reminds me of nace cip l

[@iaingarbison6986]

Where’d you get your info CC been thinking about designing a coaster I wanna read through the standard

[@CoasterCollege]

ASTM themselves, my college had the book. Scanned copy in description.

[@Coyotek4]

So what is it about Tagada rides that makes them illegal in the U.S. but popular elsewhere? And how long ago was that? I remember riding a Tagada ride at Morey's Pier (the one with Sea Serpent) back in the late-80s or early-90s.

[@CoasterCollege]

They are banned federally to my understanding, and do not comply with ASTM.

[@ThrillsofColdplay]

They are pretty crazy you are sitting without a restraint and can sit up and go in the middle with other people if you would like and that can cause injuries. I personally haven’t ridden one but I watch videos of them

[@RideManDave]

I’m not sure that’s entirely accurate. First of all, Federal authority extends only to portable rides, in spite of Sen. Markey’s attempts to change that. Second, I’m not entirely certain that they aren’t ASTM compliant. The bigger issue is, what operator would want to risk operating one?

[@Kenet3351]

With the G limits, does that mean Intimidator 305 as originally constructed wasn’t ASTM compliant?

[@CoasterCollege]

I don't know how many Gs it pulled, but it's possible

[@kamsavart]

I see that X2 isn't on here

[@VelocicoasterFanboy]

G-force limits?

[@CoasterCollege]

G Force Limits!
