All-Weather Pavement Marking System

Wet road conditions make it difficult for drivers to see conventional pavement markings, a situation that is especially hazardous in work zones where lane shifts are common. The All-weather Pavement Marking System incorporates specially designed wet reflective optical materials into pavement marking paint to make it easier for drivers to see markings on wet roads and respond appropriately. 3M will use the grant to adapt its product for cost-effective temporary use in work zones. Award amount: $499,277.

Automated Pavement Marker Placement System

Applying raised pavement markers manually is time-consuming and dangerous for workers. The prototype device, which can be mounted on standard equipment, will automate the process of reflective marker installation on roads. Initial tests showed the system reduced labor hours, construction time and risk of worker injury. Award amount: $405,560.

Leetron Advanced Mobile Retroreflectivity Measurement of Pavement Markings

About ½ of all traffic fatalities occur at night even through only about ¼ of travel occurs after dark. Retroreflective pavement markings help drivers see the road ahead at night and must be maintained to be effective. Transportation agencies need a safe, reliable and efficient way of collecting retroreflectivity data for their pavement markings. The Leetron system provides a faster, more efficient quantitative evaluation of the retroreflectivity of markings through a real time tracking system that counters motions and environmental effects. Award amount: $210,825.
