					   Car Crashes
And how to prevent them


    By Team USA
               Problem
Our problem is car crashes. Our team
has realized that car crashes cause
millions of deaths each year.
                 Analysis
•   Prevent car crashes by identifying what
    causes them
•   We have concluded that humans are at
    fault
•   Alcohol consumption, speeding, and
    carelessness are all human errors
•   Preventing human error is an exceptionally
    important part in preventing car crashes
                Approaches
How do we target the human error?
Alcohol- a curfew
Speed limit-enforcing (good or bad)?
Carelessness- cell phone turn off app
Human error-create a system, (like GPS)
that can take out the human variable or at
least make the variable less vital.
              Solution
Taking out the human error affects all the
other problems. So if we create a GPS
system that can find out all the speeds of
the cars in front and prevent shockwave
traffic jams, then we can eliminate many
of car crashes.
    Shockwave traffic Jams
A shockwave traffic jam is a car jam where
a car has stopped and speeds up again.
But the cars behind have to slow down to
not hit the car in front of them and then
they speed up and the cycle continues.
                   Video
This is a video of a shockwave traffic jam.
Sooner or later you will see cars stop then start
again. The wave will continue unless the cars
either leave the road or eventually crash.
