RE: Stupid Truck Driver

A dump truck took down a pedestrian overpass in my city just a couple of weeks ago in the exact same way!

I've never driven in a dump truck, but wouldn't there be alarms to alert the driver that their bucket it up?

RE: Stupid Truck Driver

LOL
Love the shocked comments.

I wish the video was rationally wide instead of moronically narrow.

Sad no one was able to signal the driver. It looks like, fortunately, all the other vehicles were spaced just right to prevent any fatalities.

RE: Stupid Truck Driver

Check out 11foot8.com If you find trucks running into bridges interesting. Some guy has a bunch of video cameras rolling 24/7 on the same bridge in Durham, NC. Great commentary. His youTube channel has at least 100 different videos of trucks hitting the same poor bridge.

I can't believe it is still standing.

RE: Stupid Truck Driver

jg2828 - 11foot8 They don't hit the bridge - the railroad put a beam across, a little shorter than the bridge so that anything that fits beneath the beam clears the bridge. They now have a height sensor and a huge sign and still drivers fail to understand the height of the vehicle they are in.

RE: Stupid Truck Driver

11foot8, yup, lots of car-nage, or I guess, truck-nage winky smile

Seems to me that the cost of just cleaning up the debris for each collision with the bar would pay for a sensor that measures the height of the oncoming truck and force the light to stay red until the truck turns off to one of the side streets.

RE: Stupid Truck Driver

IRstuff - If it stayed red, how would anyone ahead of the truck get through/how would it trigger in time to stop a truck if it's measured just as the truck gets to the light?

The current height sensor setup triggers a sign with "TOO TALL, TURN NOW" or the like, but people still think it doesn't apply to their vehicle. Maybe they need to add a counter with the number of hits the protection beam has taken. "HIT 145 TIMES."

At least it's not like the other, nastier buddy, 11Foot8's Evil Little Brother (10Foot6) that includes the collide-o-matic sidewalk: https://www.youtube.com/watch?v=V3-UugI0JoA It's known for the famous lobster-truck fire.

RE: Stupid Truck Driver

I believe that the famous 11-foot-8 underpass *has* installed such red lights, but the carnage continues.

Wasn't it in Sydney Australia where they had to install a system to dump a wall of water in front of the trucks to make them stop?

Let me find a picture... yes, with a giant projected STOP sign. I'll bet that they still have the occasional incident.

RE: Stupid Truck Driver

Yes, it seems odd they don't alert the trucks down the block. It takes humans time to process information.

RE: Stupid Truck Driver

Never be amazed or surprised by a driver's ability to hit something with his vehicle. When I was still operating wreckers I saw all manner of bridges and signs get hit, and also one car that fell off a transporter.

RE: Stupid Truck Driver

Thanks for the link 3DDave. I hadn't seen the 10 foot 6 bridge video. That one seems to do a lot more damage, completely ripping the boxes off the trucks instead of just peeling them open.

RE: Stupid Truck Driver

Ah !!! It just dawned on me that they use the water curtain as the image screen! Cool!

Keith Cress
kcress - http://www.flaminsystems.com

RE: Stupid Truck Driver

Yes but why? Is it because if you simply dropped a screen or curtain it would be harder to reset? Bearing in mind that presumably some wagon is going to have to spend some time backing up anyway.
I'm guessing that there is a sound case for using that technology but I wonder what the reasoning is.
A screen wouldn't need a projector (unless the driver wasn't using his lights) and how visible is a projection onto a curtain of water when the sun is shining brightly?
I will concede that it's very cool though!

RE: Stupid Truck Driver

Good points Rob. With water there is nothing to hit. There could well be cars ahead of the offending truck that a roll-down would catch.

RE: Stupid Truck Driver

As a kid, I thought the Army's bazooka was the world's coolest weapon.
Now, rig one with a trigger hooked to a "you are still too tall" sensor behind the overhead beam .... 8<)

A Star Wars horizontal light sabre would work too.

RE: Stupid Truck Driver

"Now, rig one with a trigger"

Not going to save much money or time that way; there'll still be debris on the roadway.

Might be better to make use of the curvy curb in the 10ft6 bridge, which seems to be really good at diverting vehicles, so the trigger shifts the curb and force the truck into a right turn.

RE: Stupid Truck Driver

RobWard, my guess is this:

Stopping sight distance for a passenger car is ~500 feet (150m) at 55 mph (80 km/h). A loaded truck needs more than that, so let's assume the screen is triggered when the truck is 700 feet (200m) from the tunnel portal. At 2.5 second headways, there could be three vehicles between the portal and the overheight truck. Probably ten vehicles if they drive like NY City drivers.*

So, several of those vehicles are going to be closer than stopping sight distance to the portal when the system is activated. They can go through the water curtain without damaging anything except perhaps their undershorts. A physical screen would be damaged when the car collided with it.

I was wondering how well it shows up in daylight, too, especially when the sun is low on an east-west roadway.

*I was told the NYC standard is, if you can see the back tires of the vehicle in front of you, you're not tailgating.

RE: Stupid Truck Driver

Since the tunnel is dark inside and the STOP is projected from inside the tunnel through the water, it's probably noticeable. The report seems to indicate the operation is manual from the tunnel control room, after the driver has gone past multiple signs. https://www.youtube.com/watch?v=NoTMC-uxJoo

RE: Stupid Truck Driver

So, the water curtain deploys in front of me.
I hit the brakes, hard and fast.
Right behind me is a very large truck.
The truck driver is not paying attention.
He has not noticed multiple warnings.
He may not notice my brake lights.
OUCH.
Bottom line.
YOU CAN'T FIX STUPID.

RE: Stupid Truck Driver

Waross, Why have brake lights at all?

RE: Stupid Truck Driver

Why don't they just make some sort of sacrificial barrier that the truck would collide with prior to hitting the bridge. Something (or several of them) that would get the driver's attention (without damaging the truck) well in advance of hitting the bridge. If need be, set a camera up to catch the plates so they know whose insurance to bill for the replacement of said sacrificial device. Or maybe it doesn't even have to be sacrificial. It could be a series of spring loaded batterers that beat the hell out of the truck making loud noises and whilst also slapping at the windshield.

RE: Stupid Truck Driver

Spartan5 - according to the Australian news report the tunnel operators say this had happened 3-4 times/month. Which seems to be a lot of colliding with something. I'd say it is fair to assume the truckers can read and they have 2 large signs well ahead of the water wall to do so.

The Australian Trucking Association opined that the tunnel was created without them getting in about allowing oversized vehicles and therefore it is all the tunnel designer's fault.

In the example footage there is an open top truck that is overloaded with dirt or garbage or some such which would likely be peeled off and dumped behind the truck, closing the lane anyway. https://www.liveleak.com/view?i=0da_1368144067&...

Funny thing, I'm reviewing plans for a barrier above a low clearance bridge. Believe me, the beam isn't going to be sacrificial; it's gonna be the truck and possibly the driver if the beam crashes down on him. It weights 50K. banghead

RE: Stupid Truck Driver

One of my favorites for 11foot8 is the RV which loses 2 roof-mounted AC units. Yup. It's not just the height of the vehicle that matters. Also, it's a good idea not to follow trucks too closely under low clearance bridges and tunnels.

RE: Stupid Truck Driver

Something I tell my daughter, "Every test is a reading test", but I guess they are also eye charts.

Every sign is a reading test, and there are so many who don't, can't, or won't read.

RE: Stupid Truck Driver

Not too long and we will be saying "Stupid robot" and slowly inching towards being ruled by Skynet and a legion of robots made to look like the former governor of California.

RE: Stupid Truck Driver

you mean like a robot trying to drive a 57" car UNDER a 28" trailer at 90mph

RE: Stupid Truck Driver

That's hardly reserved for robots as Jane Mansfield's death indicated.

The more likely result in robotic vehicles is to default to some safe condition, such as stopping, in a situation that is ordinarily seen as completely safe to proceed. Google cars vs bicycle riders, for example, because the cyclists slow, but don't completely stop at the cross street.

RE: Stupid Truck Driver

I think he's referring to the Tesla that failed to stop because it was not programed to see a tractor trailer.

RE: Stupid Truck Driver

I took it as a comparison of a robot driver vs a human driver.
In both incidents, the car and driver lost, the truck won.
