Traffic deaths declined for years, bottoming out at 39,250 killed in 1992, then began to increase again. In 2002, 42,815 people died in traffic accidents. But more vehicles drove more miles in 2002 than in 1992. In fact, the government says that motor vehicles traveled 2247 billion miles in 1992 and 2830 billion miles in 2002. Reports on transportation use deaths per 100 million miles as a measure of risk. Compare the rates for 1992 and 2002. What do you conclude?
