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.
