A Retroreflective Road Lane Marking Tape 1,000X Brighter than Existing Technology

Approximately 1,282 fatalities on U.S. interstate highways in 2020 were due to nighttime road departures. A new ultra-bright retroreflective lane marking tape can save lives as well as offer both a very short payback period and a very substantial benefit/cost ratio over its useful lifetime.

The TRB IDEA (Innovations Deserving Exploratory Analysis) Program's NCHRP IDEA Final Report for Project 228: A Retroreflective Road Lane Marking Tape 1,000X Brighter than Existing Technology details a new product which uses a transparent polymer film with prismatic patterns formed into the top and bottom surfaces to accept light from approaching headlights and to efficiently retroreflect this light back to the driver and sensors of the vehicle at an unprecedented level.
