• Abstract:
  The safety of nighttime drivers is enhanced by the better visibility of “retroreflective” pavement markings. Retroreflective markings reflect light (such as car headlights) back along the same path it came from -- in the case of headlights, back toward the driver of the vehicle. Retroreflectivity is achieved by embedding tiny glass beads in the paint or other material used for the markings. ; The effectiveness, or retroreflectivity, of the pavement marking is measured as a ratio of the reflected light visible to the driver compared to the light entering the glass beads. Monitoring the reflective properties of highway markings is vital for maintaining safe conditions and deciding what types of markings to use.
