Description

Highway fatality rates 1987-2007

Format

A dataset with 21 observations on the following 3 variables.

Year Year (1987-2007
FatalityRate Number of fatalites on interstate highways (per 100 million vehicle-miles)
StateControl 0=1987-1994 or 1=1995-2007

Details

In 1987 the federal government allowed the speed limit on interstate highways to be 65 mph in most areas. In 1995 federal restrictions were eliminated, so that states assumed control of setting speed limits on interstate highways. This data set compares fatality rates for years before and after the states assumed control for highway speed limits.
