Effect of a Pavement Marking Countermeasure on Improving Signalized Intersection Safety
On the approach to a signalized intersection, there is a length of roadway known as the dilemma zone where it is difficult for drivers to decide whether to cross or stop at the intersection at the onset of the yellow signal. This paper proposes a pavement marking countermeasure for signalized intersections to assist drivers in making a clear stop/go decision at the onset of the yellow change interval. The countermeasure is a warning word marking placed on the pavement of the upstream approach to a signalized intersection and is sufficient to permit vehicles cruising at the speed limit to stop safely before reaching the intersection stop bar. A driving simulator experiment was conducted to compare driving behavior at intersections with and without the marking. With the pavement marking, drivers tended to stop when the signal change was encountered at farther distances from intersections and to cross intersections when the signal change was encountered at shorter distances. All subjects gave the countermeasure a positive evaluation and most felt that it should be applied to the real road. These results suggest that the pavement marking countermeasure would have a positive effect on signalized intersection safety.
