Laserlux® FM Vehicle Front Mounted Pavement Retroreflectometer

Adding to RoadVista’s® long history of vehicle mounted mobile retroreflectometers (MRU’s), the Laserlux® FM (LLFM), front mounted retroreflectometer is ideal for agencies tasked with assessing the retroreflectivity of their pavement markings to comply with the FHWA’s MUTCD minimum retroreflectivity requirements and other contractual requirements. It allows operators to quickly identify problem areas, saving time and money by showing them where to focus their re-striping requirements

The Laserlux® FM is the safe, smart and simple solution to meet this challenge. It provides continuous pavement marking assessment and evaluation within the flow of traffic wit a front mount design that allows for full-lane measurement on a single pass.
