Abstract

An experiment was performed to determine the effectiveness of special pavement markings in reducing excessive traffic speeds at rural and urban two-lane roadway locations with sharp horizontal curvatures. The experiment was conducted at a single location on a suburban two-lane secondary road in Northern Virginia that includes a sharp left curve preceded by a long tangent section. An experimental pavement marking with the word SLOW was installed approximately 20 feet before the curve. A decrease in vehicle speed of approximately six percent overall and seven percent during daytime and late night periods were recorded. Despite these findings, relatively little use has been made of these innovative pavement markings in the US.
