- Board Meeting Animation: Truck-tractor Semitrailer Median Crossover Collision with 15-Passengar Van, Munfordville, KY, March 26, 2010
Presented September 18, 2011
This three-dimensional animated reconstruction shows the accident sequence for a collision between a combination vehicle and a 15-passenger van on Interstate 65 (I-65) in Munfordville, Kentucky.
This animation illustrates the overall accident sequence from just before the combination vehicle left the roadway until the vehicles were at their final rest positions. The motions of the vehicles shown in the animation are based on the reconstruction of the accident. Computer simulation models were used to calculate the motion of the vehicles prior to the collision between van and the tractor of the combination vehicle. These computer simulations used the initial speeds (calculated to be near the posted speed limit of 70 mph) along with the three-dimensional survey data of the physical evidence to reconstruct the motion of the vehicles. The post-collision motions of the vehicles could not be simulated precisely because of limited physical data and model limitations, and the motions shown in the animation are based on the physical evidence of impacts and a general reconstruction of the post-collision trajectories of the vehicles. For a more in-depth discussion of the reconstruction and its limitations, please refer to the accident report. The animation does not depict the weather or visibility conditions at the time of the accident. The animation includes audio.
The animation sequence shows the combination vehicle departing the left lane of southbound I-65 at a shallow angle and entering the 60-foot-wide depressed earthen median between the southbound and northbound roadways. The combination vehicle then travels across the median, striking and overriding the four-cable, alternating post median barrier adjacent to the left shoulder of northbound I-65, and then crosses the left shoulder and enters the travel lanes of northbound I-65. At that time, a 15-passenger van is traveling northbound in the left lane. As the combination vehicle crosses in front of the 15-passenger van, the 15-passenger van strikes the tractor of the combination vehicle. The 15-passenger van rotates clockwise, becoming engaged with the combination vehicle, which continues across both travel lanes and the right shoulder of northbound I-65. As the combination vehicle and 15-passenger van travel across the right shoulder, the van separates from the combination unit, strikes a vertical, cut rock slope, and rebounds back into the travel lanes, coming to rest in the left lane of northbound I-65, facing south. The combination unit tractor strikes the rock slope beyond the shoulder and rolls onto its right side. This animated sequence is approximately 11 seconds in duration.
The animation is shown from three different viewpoints. The first viewpoint is a chase view following the combination vehicle with the label "Combination vehicle view", the second viewpoint is a chase view following the 15-passenger van, with the label "15-Passenger van view" and the final viewpoint is an overall view that is focused on the combination vehicle as it crosses the median and overrides the four-cable, alternating post median barrier, with the label "Median crossover and impact view". The three views are presented twice divided by the title "Repeat of Animation Sequence".
Crossover accidents happen in the blink of an eye, for all of your brilliant commenters wondering why the van didn't just "swerve out of the way" at 70 mph. The TRUCK DRIVER was distracted and fatigued. The company Hester, Inc was shut down three months later, but the owners just did a Bad Accident Chameleon and resurfaced with a new DOT number. They even had the nerve to keep Hester in their name! Only one passenger of the Mennonite family traveling to a wedding survived, a baby strapped in a carseat that was in the rear most seat row.
Massively important lesson to parents about the importance of child safety seats in vehicles. Thanks for the additional info.
Each going 65 mph it happens in the blink of an eye. I suspect this is a case of truck driver looling at the inside of his eyelids....sleeping.
I'm captain on towboat,we have Deadman alarms. If no movement in so many seconds while moving it sets off alarms on boat. What im saying is that could also on a truck shutdown engine and apply brakes after so many seconds of no driver movement.
Central median provides a false sense of security.
only if it's a semi. they'll go through cement barrier. it stops most normal cars though.
@@x-cry1036 it does not stop full size pick up trucks that are loaded with trailers, especially oversize dually pick up trucks
@@cruzdeleon1888 "most"
Why are they both in the left lane?
?
They’re driving on the interstate?
How did the tractor unit enter a rock face?
crushed and turned downwards. but they were to lazy to animate that
Those "cheese grater" cable barriers are worthless, TBH.
12 dead...Yikes!
Cause? Trucker falling asleep at the wheel? Occupant outcomes?
Pretty sure the all or most of the van occupants died. If I remember correctly they were amish or something similar.
This accident was a example of the freedoms that conservatives celebrate.
1. Freedom from proper oversight of the commercial trucking industry (get the government out of the way of business):
Truck driver had a terrible driving record, yet was allowed to keep driving. Employer had a terrible safety record, falsified logs, ordered drivers to commit illegal actions, and engaged in deceptive business practices in order to retain its license to transport freight, yet the punishments they faced were negligible, amounting to a few tens of thousands in fines.
2. Freedom from safety laws (don't need no gubmint to coddle us):
Driver was using his cell phone and lost control of his vehicle. (Road conditions and mechanical issues were not a factor.) Driver only had 4 hours of sleep the night before. Crossover barriers in that great, free conservative state of Kentucky were inadequate and cheaped out. Passenger vans with more than 10 seats (this one had 15) were exempt from Kentucky seatbelt laws. 3 out of 12 people in the van survived, most of the dead weren't wearing their seatbelts (guess it mussed up their clothes). (note - truck driver died, too.)
Yep, Freedum, Freedum, Freedum!! Dat's the conservative way!
Steve Rogers .... Dumbass....
Ozzie: You and anyone upvoting your comment would be the actual unAmerican "Dumbass" here. EVERY item he posted is TRUE and you are ALL morons in deadly denial. Consumer protection is the LOWEST priority of this administration. Vying for last place with environmental protection.
You and Sergent Stupid Steve up there both deserve a medal but they couldn't put it around your necks because your heads up to the shoulders are jammed in your asses. Neither one of you have a clue about what you're talking about unless someone asks you, then you're both experts. Do the world a favor you liberal half breeds, STFU and let the people who have a clue do the real jobs. Idiots, pure and simple. No wonder you're both loser liberals.
Please update title to reflect passengar should be spelled as passenger
Wow
why hit a semi head on?.....why not simply brake, swerve, move your vehicle a little.....why hit head on?
I agree with you. I'd have gone to the medium.
@@shaggydog563 and be crushed by the trailer. panic swerve to the right was what they decided in the two seconds they had.
@@x-cry1036
That's the right move statisticly..you would expect an attempt to recover by the semi..
However what is depicted here is no response by the van at all.
If you apply that logic to any accident that accident could be avoided.
I'm not blaming the van driver in the least, but if this animation is accurate, it doesn't look like he/she applied the brakes or took any evasive action whatsoever. Maybe texting? There was time to do *something* if he/she was paying attention.
well the simulation doesn't show everything. for instance, the crash happened early in the morning (5am) at the end of march. definitely would have been harder to see than the simulation makes it out to be.
When driving at higher speeds you get tunnel vision, the drivers attention is facing forwards and only forwards with limited field of view. Most events happening to the side are not processed by the brain. When the truck entered her active FOV to late to react
At that time of day, the van driver would've seen headlights coming towards them. Probably thought the truck was just another passing vehicle instead of a vehicle coming straight at them.
The van drivers choices were as follows: 1. Turn right to avoid collision with truck and crash head on into granite wall. 2. Turn left to avoid collision with truck and crash head on into on coming traffic at 70 mph. 3. Crash into truck.
I would say the van driver didn't stand a chance!
@@chrisstromberg6527 that's a wide median. The van driver wouldn't necessarily hit oncoming traffic. However, being as how it was still dark out I don't think the driver would have seen the problem in time to react.
How could you NOT see a semi coming at you?
Most likely right in line with the a pillar. My work van requires i do a double take looking left every intersection i stop at. Sucks but had too many close calls because of it
By the time you realize whats happening on, its most likely too late
no brake lights in the animation?
First, no one expects to see a semi coming right at them. It takes a moment to get past that surreal aspect. Then what? Dodge left or right? Could you tell where the semi was going to end up while it was still bouncing around in the median? And yeah, like someone else said, no brake lights in the animation.
passengar van? never heard of that ;) just saying
as opposed to a cargo van.
whut? you've obviously never van-pooled
+steve b
They were talking about the misspelled word in the video title.
Passengar Van instead of Passenger Van...
Steve b [for BOZO] Maybe next time pause to check other possibilities [in light of your own abject anger-management stupidity] before hurling insults. NI Rail posted witty sarcasm and even included a smiley. Get a clue, rote-learning dotard.
