Title: Retroreflectivity: Raising the Nighttime Brightness of Traffic Signs and Markings
Author/Presenter: Hatzi, Peter
Publication Number: HSA-1
Abstract: Retroreflective sign sheeting and pavement marking paints degrade with effects of weather and traffic. In a highway environment, retroreflectivity is important because it promotes efficient traffic flow, driving comfort and highway safety. The goal of this project is to improve the in-service performance of traffic signs and markings by creating tools, retroreflectometer equipment for measuring the nighttime visibility of signs and markings for the purpose of:
- Development and commercialization of tools for measuring sign and pavement marking retroreflectivity
- Encouraging the implementation of guidelines nationwide by providing workshops on the guidelines and the technology.
- Encouraging implementation of sign and pavement marking management programs in state and local highway agencies.
