Impact of New Speed Limits on Kansas Highways
Kansas' law increased speed limits on most of its highways in March 1996. The detailed research study reported herein concentrated on analyzing the before and after Kansas' speed and accident databases. In regard to speed analysis, the t-test was applied to investigate whether significant increases in 85th percentile speeds were noted during the after period on both interstate and 2-lane rural highways. In this case, a 3-mph increase in 85th percentile speeds was noted on interstate highway sections and a 3 to 5 mph increase was noted on the 10-mph speed limit increased 2-lane highways. None was noted on the 5-mph speed limit increase on the 2-lane highways. The 3-Step Sequential Analysis approach was utilized to analyze the before-and-after Kansas' accident database.
