Road Weather

Reliable Data. Confident Decisions. Safe Roads.

Around the world, professionals rely on Lufft’s stationary and/or mobile road weather information systems. They are used by Ice and Road Weather Detection (RWIS) and Traffic Control or Vehicle Management Systems (VMS), road maintenance depots, and operation managers to monitor road conditions, friction, temperatures, visibility and more. Data is used to design efficient operational plans and to keep roads free from snow, ice or water film layers to protect from dangerous traffic situations.

LUFFT MARWIS on Tour - The Mobile Road Weather Sensor - Product movie

A lot of technology monitors the weather on the lifelines of our civilization. However, there are huge gaps in the measuring networks, making error-free forecasts impossible even with a great deal of experience and sensitivity. More closely meshed monitoring networks? Much too expensive. An affordable technology that would close all these gaps would be like a miracle.

And here's the miracle: MARWIS - Lufft's first mobile road weather sensor.

Increasing Safety With RWIS Lite

The best way to be aware of potential risks on the road is to establish a dense network of monitoring stations. Fortunately, there is a plan B. Streamlined Road Weather Information Systems (RWIS) can fill the gaps and ensure availability of essential weather and road surface information. Find out more on our blog.
