  Crash incompatibility   (Site not responding. Last check: 2007-09-19)
Crash incompatibility, crash compatibility, vehicle incompatibility, andvehicle compatibility are terms in the automobile crash testing industry.
The most obvious source of crash incompatibility is mass ; a high mass vehicle such as avan or SUV will tend to cause much more serious damage in a crash with a lighter vehicle suchas a typical sedan or compact car.
Crash incompatibility is an area of active study, although to date only a small fraction of crashtests focus on two-car crashes, and an even smaller proportion are properly designed to address incompatibility issues.

 Smart Motorist - Relationships Between Vehicle Weight and Occupant Death Rates   (Site not responding. Last check: 2007-09-19)
For each vehicle type and crash configuration, relationships between vehicle weights and death rates were reviewed to explore the role of incompatibility in passenger vehicle occupant deaths.
Examined were deaths inside the study vehicles in two-vehicle and single-vehicle crashes, deaths inside any other vehicles that crashed with the study vehicles, and the relative death risk when study vehicles collided with each other in front-to-front and front-to-side crashes.
These results reflect both single- and two-vehicle crashes, and the latter account for 48 percent of all car occupant deaths, 35 percent of all pickup occupant deaths, and 29 percent of all utility vehicle deaths.

The compatibility of a vehicle is a combination of its crashworthiness (the vehicle’s capability of withstanding the effects of a crash) and its aggressivity when involved in crashes with members of the vehicle fleet.
The incompatibility is induced by the difference in the mass, stiffness and geometric of both vehicles.
Crash incompatibility is of concern in all two-vehicle collisions.

 NHTSA Vehicle Safety Rulemaking Priorities: 2002-2005   (Site not responding. Last check: 2007-09-19)
Crash avoidance problems are identified through research, petitions, and other information received from the public.  In order to develop effectiveness and benefits data and to develop solutions, it is essential to estimate with some degree of certainty problem size and crash or injury savings as a result of changes in vehicle performance.
If a crash does occur, the agency strives to reduce the severity and increase the survivability of the event.  This is known as crashworthiness.  Eighty percent of light vehicle occupant fatalities in 2000 were the result of collisions in which the initial crash event was an impact to the front or side of the vehicle.
Real world crash statistics indicate that 42 percent of towaway frontal crashes are full-frontal and 56 percent are offset frontal.  Even after all cars and light trucks have frontal air bags, we estimate there still would be 8,000 deaths and 120,000 moderate to critical injuries in frontal crashes each year.

 The Pentagon No-757-Crash Booby Trap
A crash study suggests that the over-300-mph impact of a jetliner with the Pentagon's heavy masonry facade would have reduced the entire aircraft -- and certainly its relatively light wings and tail -- to confetti.
Bart's theory is consistent with the crash of Flight 77 at the Pentagon, but not with the official story that it was hijacked by Muslim terrorists, since it assumes the plane was prepared prior to the attack.
The idea that no 757-sized airliner crashed into the Pentagon on 9/11/01 is attractive to many skeptics because it contradicts a fundamental tenet of the official story, is supported by common-sense interpretations of photographs of the crash scene, and provides an explanation for the suspicious lack of physical evidence supporting the official account.

While the incompatibility of vehicles in crash situations does not appear to be a new issue, the recent growth in LTVs as a percent of the U.S. fleet requires that continued research and development resources be invested to further understand and find solutions that ameliorate this potential problem.
A recent analysis of crash data revealed that LTV-to-car collisions result in a higher rate of fatalities than car-to-car collisions in both frontal and left side impacts and that side impact LTV-to-car collisions produced a higher rate of fatalities than frontal impact LTV-to-car collisions.

 Advocates for Highway and Auto Safety
Crash avoidance standards and designs address a number of vehicle operating systems, some of which are often taken for granted as direct contributors to the safe operation of a car or light truck.
For crash avoidance operations, for example, headlamp designs are critically important not only for providing sufficient illumination to drivers to see the road and traffic control devices such as signs and pavement markings, but also to supply necessary light without generating disabling glare for other drivers.
Whether front or side crashes, it has become rapidly apparent that improving the safety of small vehicles in crashes with larger vehicles requires a systems engineering approach of both further improving the crash management capabilities of smaller vehicles as well as softening the severity of impacts by larger vehicles.

An analysis of U.S. crash statistics will be presented to explore the aggressivity of LTVs in impacts with cars and identify those design imbalances between the cars and LTVs, e.g., mass, stiffness, and geometry, which lead to these severe crash incompatibilities.
Of the 5259 fatalities in LTV-car crashes in 1996, 81 percent of the fatally-injured were occupants of the car.
Only two-vehicle crashes in which both vehicles were either a car or an LTV are considered in computing the fatality count and the crash involvement count.

 Blame Drivers, Not SUVs, for Deadly Accidents
A May 29 Car Culture column said that in a two-vehicle crash between a sport-utility vehicle and a smaller car, the occupants of the SUV are more likely than the car's occupants to be killed.
In a two-vehicle crash with a smaller car, the occupants of the SUV are more likely to be killed than are the people in the car, according to the IIHS report, which is based on a study of U.S. highway traffic fatalities during years 2002 and 2003 involving vehicles made from 1999 through 2002.
But SUV-car crashes are statistically few -- again, accounting for 7 percent of the deaths in cars and 10 percent of those in SUVs.

According to NHTSA's 2000 fatality data, passenger vehicle deaths in rollover crashes declined slightly from 10,133 to 10,108 in 2000.
Researchers Marc Ross and Thomas Wenzel, at the request of the Los Angeles Times, just this month updated a survey they completed last March, finding that most mid-size and large cars are as good or better than the average SUV at protecting their own drivers, and much more protective of drivers than the average pickup.
After two days of meetings, the two groups wrote to Dr. Runge, saying that the greatest danger to vehicle occupants from incompatibility is in front-to-side crashes, and recommending that the highest priority, "in the short term," should be placed on enhancing "the protection for occupants inside the vehicles struck in the side.

Crash incompatibility is not a phenomenon that arose with sport utility vehicles.
Trucks have long been incompatible with cars, and cars are incompatible with motorcycles, bicycles, and pedestrians.
If it has, then the number of car drivers killed in two-vehicle crashes, as a fraction of all car drivers killed, should have risen dramatically as SUV sales soared.
