RE: Stupid Truck Driver
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
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.

I can't believe it is still standing.

RE: Stupid Truck Driver
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
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
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
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
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
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
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
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.

RE: Stupid Truck Driver
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&...
RE: Stupid Truck Driver
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.

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

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.

In both incidents, the car and driver lost, the truck won.
