Professor Gates speaks to the Chicago Tribune about Chicago's mix of short yellow light times and red light cameras

The Chicago Tribune recently reported that Chicago has the nation's largest red light camera system and the shortest allowable yellow lights-a unique and dangerous combination that makes rear-end crashes more likely across the city. WSU professor of civil and environmental engineering Timothy Gates, whose work is the basis for revisions to national standards on signal timing told the Tribune, "I am very surprised that this hasn't become more of an issue in Chicago because the yellow light time is so much shorter than conventional wisdom suggests. Of course that's going to lead to more accidents, especially rear-end accidents."
