Measurement practise for road markings

Measuring retroreflection from road markings need to be done in a structured way if you want to obtain usable measurement results

You need to make sure the instrument is in good shape and recently calibrated.

You need to design a measurement program which offers results representative of the markings you investigate.

You need to decide how often to measure the markings to ensure performance according to the requirements of the standard.

DELTA has summarised the main parameters to take into account when planning a measurement program, and we have come up with proposals to the design of the program.

Do it right first time, it saves time and provides a better base for making management decisions.
