Explain to someone who knows little statistics what that means. The speed limit is set at the value that will have 15% of the vehicles on that road traveling at a speed less than the speed limit. The speed limit is set at the value that will be 0.85 standard deviations above the mean. The speed limit is set at the value that will have 85% of the vehicles on that road traveling at a speed less than the speed limit. The speed limit is set at the value that will have 85% of the vehicles on that road traveling at a speed greater than the speed limit.
