SPR 2013 Prime KTC: Wet Night time Delegation

An effective method of providing roadway delineation during wet-nighttime conditions has been the source of research studies in Kentucky for decades. Typical traffic paint is not effective during wet conditions. Past research has evaluated various types of marking materials and raised markers. Snowplowable raised pavement markers have been used, but there are problems with durability if the pavement is not maintained. A recent research study recommended an evaluation of: a) alternative snowplowable marker designs, b) paint and tape marketed as having the capability of providing delineation during wet conditions, and c) use of centerline and edge line rumble stripes. The problem, which will be addressed in this research, is the lack of an effective and durable method of providing delineation during wet-nighttime conditions.
