Road marking’s visibility, the retroreflectivity is correlated with roadway safety, it directly presented as the night visibility (RL) of pavement markings. The TBTRMR-VM vehicle-mounted marking retroreflectometer allows a constant and efficient assessment of the state of road markings while maintaining traffic flow. The detection accuracy is consistent with the handheld retroreflective readings.
The major components of the system are the host, computer processing system, and DMI (distance measuring wheel). The host is consist of optical measurement system, control system, imaging driver assistance system, height / tilt compensation system and Beidou positioning antenna.
