Vehicle mounted retroreflectometer for efficient and safe continuous measurements

• Measure the night visibility (R_L) for all types of road markings
• Handheld precision at up to 150 km/h (93 mph) without obstructing the traffic
• Double and even triple lines are recognised and measurements are automatically stored separately
• Industrial grade ruggedized touchscreen tablet
• For all lighting conditions also bright sunlight
• GPS with dead reckoning (DR) providing accurate GPS signals even in urban canyons and tunnels
• Measurements can be evaluated with the included mapping and data analysis software “MappingTools” thus providing a comprehensive solution
• All important data are recorded at the same time: R_L, day contrast ratio, GPS coordinates, ambient temperature (°C/°F), relative humidity (rH %), speed, picture, voice recording, as well as date and time
• In accordance with true CEN geometry of EN 1436 (R_L), ASTM E1710 (R_L) as well as ASTM E2177 (R_L wet)
