Does anyone know their method (and how it has evolved over the years) for detecting a crash from the raw feed?
Not 100% on this but I think I remember reading that they just look at the audio and then look at the video near the sharp peaks

They tried an electronic warning sign that lights up when a truck is too tall, but drivers still can't resist the lure of the hungry bridge: https://youtu.be/YQssl0sM9As?t=6 , https://youtu.be/cZrOcCXNq5c?t=5 , https://youtu.be/iQfSvIgIs_M?t=32 Might have been better off erecting a giant, no-tech billboard picturing a previous crash.

That water curtain and projector looks like something adapted from the casino, convention center and special event industry.
There are some very capable systems being used in shows around the world:

Is it? Shouldn’t the goal be to protect the driver?
If the goal was to protect the driver then the bridge would be removed. The bridge carries a railway so many more lives are at stake if it's damaged.
Sure more lives are at stake, but I think the probability of physical harm to them is pretty low because
a) The bridge has been hit tons of times, and I don't think anyone in a train has been hurt yet.
b) The bridge is probably a lot stronger than the truck, so while the bridge may take damage and need to be repaired, the damage is probably not enough to harm train traffic.
c) If the bridge is damaged enough to harm train traffic, there's probably not a train coming immediately; any on-route trains can be likely stopped before they reach the bridge.

#214The Sidney Harbor Tunnel had a similar problem. They came up with an elaborate but successful solution.[1] There are detectors and huge flashing warning signs that light up. Then, there's the last-chance sign. At the entrance to the tunnel, pumps force a curtain of water straight down across the entire roadway. Then a powerful laser system projects a giant octagonal red STOP sign onto the water curtain, filling the e…

That's a total usability fail. "OVERHEIGHT MUST TURN" doesn't tell you that YOU, the driver currently approaching the bridge, are the one in control of a too-tall vehicle. I wonder if they've tried something as obvious as a static sign that says "LOW BRIDGE: CHECK YOUR HEIGHT", or a vehicle-activated sign that says "YOUR VEHICLE IS TOO TALL FOR THIS BRIDGE"

That water display is excellent! Great engineering on what appears to be a tough problem.
And what makes it even better is that it's a truly geeky solution. You would expect something like this in the homes of geek super villains like Vector (from Despicable Me) or Bill Gates (yes, I am joking here)
Totally. It just stands out. OF COURSE!
Someone found just the right use case and went for an unconventional display tech.
Love it.

Probably shouldn’t be driving so ...
There is a long list of unhelpful "Probably" statement's that don't solve the problem.
No. Really. Driving while tired is considered to be as bad as driving under the influence. HGV drivers should really be seeing rigorous testing for this but - hurdur - freedom
