Characteristics of Laserlux Operation for Mobile Retroreflectivity

Pavement markings provide a level of safety and comfort for drivers, but they must be replaced periodically due to deterioration. A performance-based pavement marking maintenance specification is potentially more cost efficient and safer than using solely a material-based marking specification, however a performance specification requires the periodic assessment of pavement marking retroreflectivity. While pavement marking assessments are tedious and potentially hazardous when using handheld retroreflectometers, mobile-based retroreflectometers may assess markings at highway speeds which improves both safety and convenience. It has been determined that proper mobile retroreflectometer operation requires the knowledge of various operational factors, which have a significant impact on the performance of the instrument. This paper reviews the practice of pavement marking assessment methods and the operational characteristics of mobile retroreflectometers so that this technology may be easily implemented to provide dependable results.
