Abstract
This invention is a novel retroreflective traffic stripe comprising an exposed top surface containing a widely spaced repeating pattern of linear light-turning prisms and a second repeating pattern of linear prisms between the light-turning prisms, over a bottom surface containing cube corner retroreflective prisms. The two types of top surface prisms are operable under dry and wet weather conditions, respectively. Both types of top surface prisms are configured to use refraction and reflection to redirect light from distant headlights into a downward direction onto the bottom surface of the traffic stripe under dry and wet weather conditions, respectively. Cube corner retroreflective prisms on the bottom surface accept the light and return it in the opposite direction.
