The point instrument has the potential for the best accuracy of measurement. The annular instrument, on the other hand, seems somewhat strange by simulating an eye that forms a circle about a headlamp. TheMethods for Maintaining Traffic Sign Retroreflectivity,,Although there are variations to this method, the basic idea is that the installation date of every sign in an agency’s jurisdiction is known, along with the type of retroreflective sheeting material used on the sign face. It is also necessary to define an expected sign (i.e., service) life for each type of retroreflective sheeting material.
