p.s. the 70 MPH is the highest speed formation publically available, that I found anyway. You could probably extrapolate from these 3 data points.

@Count Krzysztof: Done. That looks real good. Well, I have to release a taller one. When you scale up a barrel that increases the diameter which isn't correct but it's better than nothing.

@WillYart How about something for 35-40 MPH and something for 80 MPH? I have used the image above (along with another barrel asset) to produce the image I've linked below, but a couple more layouts would be great for areas where the freeways and expressways have different speeds. Thank you so much!

[edit: just realized I left out a pair of barrels in that image, but you get the idea.]

p.s. do you have a particular speed road you are dealing with? Do you prefer metric or english units? I have a lot of real world formation design drafts, I can pick the closest to your need and upload it.

@Count Krzysztof Yes, so the 4th image in this asset above is an example of a recommended formation. That formation is designed for vehicular impact at 60 MPH / 96.5 KPH. The ones marked less than 2100 kilograms can be modelled by this asset (they are either fully or partially filled with sand, which is not visible, to vary the weight). The 2100 kilo barrel I am still working on; it is slightly taller. It will take some more time, though, as the lives of 74,836 cims depend upon my urgent attention.

These are great, thank you!

Would you please be so kind as to share some of the recommended formations for these attenuators?

Neat!

Thank you :)

Nice work
