Marwis mobile road sensor on display by Lufft

German measurement technology specialist, G. Lufft is here at the ITS World Congress with a clear message: although stationary road weather information sensors have been in use for many years, even the densest RWIS network can’t cover what Marwis, the innovative mobile road sensor, is capable of.

German measurement technology specialist, G. 6478 Lufft is here at the ITS World Congress with a clear message: although stationary road weather information sensors have been in use for many years, even the densest RWIS network can’t cover what Marwis, the innovative mobile road sensor, is capable of.

Marwis transforms vehicles into mobile weather stations and delivers data in high-speed. This enables winter service vehicles, school buses, airports and potentially every driver to enhance safety and get reliable information on different surfaces. The sensor detects water film on the road, ice percentage, road status, friction, temperatures and more, providing total control over a route, in terms of safety and of time.

The measuring principle of Marwis is based on the principle of the NIRS31, introduced in 2011. Since then it has also been offered in the embedded passive IRS31-UMB and the active ARS31Pro-UMB sensor. The NIRS31-UMB was the first contactless road weather sensor from Lufft capable of analysing the road below safely from a distance of up to 16 metres. As the company points out, this is especially useful for bridges where the road surface temperatures are cooler than the adjoining road surface and invasive systems require installation bases that are too deep.

“The perfect supplement for our mobile road sensors is our WS700-UMB multifunction weather sensor because it addresses so many needs within one casing,” says Nouredine Hafsaoui. “As visitors to our stand will see, it requires only one cable connection and combines sensors for the detection of air temperature, relative humidity, precipitation intensity and type, air pressure, wind direction, wind velocity and global radiation."

    eCall misses the point and is only a tacit acknowledgement that the road safety issue has not yet been adequately addressed, according to FEMA's Aline Delhaye. According to the Federation of European Motorcyclists' Associations (FEMA), the European Commission's (EC's) ambitions for eCall implementation are premature and fail to take account of all road users' needs or of technological progress elsewhere.
