Retroreflectivity is a measure of how efficiently the pavement marking returns light from the headlamps back to the driver. In mathematical terms it is a ratio of the reflected luminance to the headlamp illuminance at a certain viewing geometry. Figure A-1 shows a simple illustration of pavement marking retroreflectivity. Figure A-1.
