Evaluating Active and Passive Crosswalk Warnings at Unsignalized Intersections and Mid-Block SitesStatus: CompleteReport Date: 01/20/2009 Summary: Researchers compared the safety effects of passive warnings (roadway markings accompanied by warning signs facing oncoming traffic) and active warnings (passive warnings accompanied by a flashing light that is either continuously flashing or activated by someone wishing to use the crosswalk) at crosswalks at unsignalized intersections or mid-block sites. The study found no significant differences between passive warnings and active warnings in encouraging more cautious behavior in motorists approaching the crosswalk and suggests the need for further research.
