Auto Transport Safety
Automobile accidents are almost as old as
automobiles themselves. Joseph Cugnot crashed his steam-powered
"Fardier" against a wall in 1771. One of the earliest
recorded automobile fatalities was Mary Ward, on 1869-08-31 in Parsons
town, Ireland; an early victim in the United States
was Henry Bliss on 1899-09-13 in New York City, NY.
Cars have two basic safety problems:
They have human drivers who make mistakes, and the wheels lose traction
near a half gravity of deceleration. Automated control has been
seriously proposed and successfully prototyped. Shoulder-belted
passengers could tolerate a 32G emergency stop (reducing the safe
inter vehicle gap 64-fold) if high-speed roads incorporated a steel
rail for emergency braking. Both safety modifications of the roadway
are thought to be too expensive by most funding authorities, although
these modifications could dramatically increase the number of vehicles
that could safely use a high-speed highway.
Early safety research focused on increasing the
reliability of brakes and reducing the flammability of fuel
systems. For example, modern engine compartments are open
at the bottom so that fuel vapors, which are heavier than air, vent
to the open air. Brakes are hydraulic so that failures
are slow leaks, rather than abrupt cable breaks. Systematic research
on crash safety started in 1958 at Ford Motor Company. Since then,
most research has focused on absorbing external crash energy with
crushable panels and reducing the motion of human bodies in the
passenger compartment.
There are standard tests for safety in new automobiles,
like the Euro CAP and the US NCAP tests. There are also tests run
by organizations such as IIHS and backed by the insurance industry.
Despite technological advances, there is still
significant loss of life from car accidents: About 40,000 people
die every year in the U.S., with similar figures in Europe. This
figure increases annually in step with rising population and increasing
travel if no measures are taken, but the rate per capita and per
mile traveled decreases steadily. The death toll is expected to
nearly double worldwide by 2020. A much higher number of accidents
result in injury or permanent disability. The highest accident figures
are reported in China and India. The European Union has a rigid
program to cut the death toll in the EU in half by 2010 and member
states have started implementing measures.
