Traffic Safety
Throughout the last quarter of a century, California has reduced and increased the maximum speed limit on all the highways. In 1974, the maximum speed limit on all California highways was reduced from 65 miles per hour to 55 miles per hour. By 1988 the state of California decided to increase the speed limit on some highways to 65 miles per hour. During the year of 1996 the state of California increased the speed limit again, to 70 miles per hour, affecting the majority of the rural interstates and rural portions of Highway 99 and 215. States throughout the country have enacted similar law changes regarding speed limits. These speed limit changes caught the interest of many researchers, causing them to conduct research regarding the positive and negative effect of such changes. After reviewing past researches, I predict traffic safety on highways will see an increase in crash rates where there are increase speed limit. I also predict there will be no significant gender differences in male and female drivers when it comes to the effect of speed limit law changes.
The following researches, analyzes traffic safety about the effect of speed limit increases and whether these effects differ for male drivers and female drivers. Ossiander and Cummings (2002) were interested in determining the affect of speed limit increase instituted on the freeway in the state of Washington in the year of 1987 and traffic casualties. From 1970 through 1994 data was collected by the Washington State Department of Transportation and was given to the Washington State Traffic Safety Commission. Using the data obtained, Ossiander and Cummings analyzed the findings using poisson regression to examine the relationship between the fatal crash rate and the speed limit increase on rural and urban interstate freeways. Based on the data given, Ossiander and Cummings were able to suggest that, after...
