The AMAC technology provides an accurate and repeatable measurement of retroreflectivity of pavement markings lines & symbols, through mobile nighttime surveys at traffic speed (no lane closures). The system can measure in one pass both lines of the lane the vehicle drives through as well as any symbols located between those lines.
Its high accurate GPS and the computer vision algorithms developed can position accurately every type of line and symbols, so that not only an assessment of the retroreflectivity is provided but also a detailed inventory of the pavement marking.
AMAC controls all factors of influence in pavement marking retroreflectivity, particularly the vehicle dynamics. The accuracy of the system is not affected by the type of driving as its transversal range of measurement is large enough so that any particular driving requirement is avoided.
