The MARWIS mobile advanced road weather information sensor can be mounted on any vehicle to collect road weather information (surface temperature, dew point, water film height), road conditions (humidity, snow, ice, frost), grip (friction), and other environmental data. It measures meteorological data and road condition information 100 times/second at a driving speed of about 50 mph (every 7-8 in.). Data can be sent via Bluetooth or delivered into any existing AVL system. Lufft USA Inc.
