Report no. 200642TS

Topics: Driver Performance and Behavior, Safety

Researchers studied the stopping patterns of approximately 400 cars, trucks and other vehicles at selected rural intersections and found that in-lane rumble strips caused drivers to reduce speeds earlier and to a greater degree than at intersections without rumble strips. This was the third in a comprehensive series of studies on the effectiveness of in-lane rumble strips.
