Title: A Retroreflective Road Lane Marking Tape 1,000X Brighter than Existing Technology
Accession Number: 01842738
Record Type: Monograph
Record URL: Abstract: This Innovations Deserving Exploratory Analysis (IDEA) program project developed an ultra-bright traffic stripe made from a thin transparent polymer film with prismatic patterns formed on both the top and bottom surfaces of the polymer film. The new traffic stripe uses neither paint nor glass beads to provide unprecedented retroreflectivity on dark highways at night. The top surface includes light-turning prisms facing in both directions of traffic. Rays from distant headlights are totally internally reflected (TIR) by a sloped surface downward onto cube corner prisms covering the bottom surface of the polymer film. The cube corner prisms retroreflect the rays in the opposite direction so these rays eventually return to the driver (and the sensors) of the vehicle. The cube corner prism technology has been successfully used for decades in traffic signs which are very bright and durable. The present innovation enables this previously developed cube corner sign technology to be applied to traffic stripes to make the new stripes as bright as road signs.
