Work zones by nature present transitions, shifts, and changes to motorists' expectations. Given these conditions, providing proper guidance to motorists is critical. With respect to pavement markings, the challenge is to provide sufficient markings, but in a temporary setting. A variety of pavement marking products are currently in use within work zones; however, their effectiveness and costs can vary widely. This research will evaluate the effectiveness of removable pavement marking products in terms of daytime presence, nighttime retroreflectivity, wet retroreflectivity, durability, and removability. |
