SciencePhoto: HT WorldBellevue Adds Grippy Surface to Downhill Intersection, Crashes Drop 78%
In 2004, Bellevue, Washington, improved safety at a downhill intersection by adding a grippy pavement surface after flashing signs and other warnings failed. This change led to a 78% reduction in crashes and an 83% decrease in crash-related costs. The Federal Highway Administration highlighted this case to show the importance of road surface improvements where stopping on slopes is required.
