Safety Effects of Raising Speed Limits to 75 mph and Higher

The objective of this research is to provide guidance to assist highway agencies in estimating the safety impacts of increasing speed limits to 75 mph or more. This should include information to support the consideration of where, when, and by how much speed limits may or may not be increased on existing facilities and newly constructed roads. The guidance should also identify mitigation strategies that may be implemented to offset potential impacts.nding.
