Safe motor vehicle travel during low light and night-time conditions requires that directional, regulatory, and cautionary information be displayed upon traffic control devices and be clearly visible to a vehicle operator. Manual inspection of road signs and markers makes regular maintenance time-consuming and expensive. Mandli Communications has developed RetroView and RetroCurve, an automated system that provides a safe, cost-effective alternative.

As an add-on component of Mandli's Digilog VX data collection system, accurate reflectivity data can now be collected from a moving vehicle traveling at posted road speeds. Luminance values are determined on-the-fly using an active infrared light sensor triggered at periodic intervals along a route along with a high-intensity black and white digital image intensity frame.

• Reflectivity collected in a single pass at posted road speeds
• Digital roadway imagery and GPS data collected simultaneously
• No asset inventory knowledge required of vehicle operator

Software

• Roadview 6
