The design of a roadway can influence driver behavior.
Making a road safer means designing it to account for inevitable human error. Driving too fast around a curve or taking your eyes off the road to look at your cell phone for just a moment can lead to deadly consequences. A more forgiving road has features that help people self-correct, such as speed feedback signs, wider roadway shoulders, and rumble strips, and then as a second layer of prevention, reduce cash severity with guardrails or gentler roadside slopes that are free from fixed objects like trees and utility poles.
