摘要：This invention relates to reflectivity measuring apparatus. This inventionprovides reflectivity measuring apparatus for assessing the integrity of road markingsincluding a light source, a light sensor and a processing means, the apparatus beingmounted on a vehicle such that, in use, the light source illuminates a reflective surface ona road marking, and wherein the light sensor detects any reflected light and the datasignal is received by the processing means, the processing means processes the data toprovide information on the reflectivity of a said reflective surface. In another aspect ofthe invention there is provided a computer controlled process for determining theintegrity of light reflective road markings, the computer being programmed to carry outthe steps of getting data on the reflectance levels of road markings; calibrating the databy multiplying the data with a predetermined calibration factor; and determining whetherthe road marking meets a predetermined acceptable reflectance level.
