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."

    More than 1.3 million people die in road accidents each year. If nothing is done, this already chilling figure risks to rise to 1.9 million deaths per year. Around 90 per cent of road fatalities occur in emerging and developing countries. Here, the mixture of population growth and higher numbers of vehicles due to rising incomes are proving a deadly combination, as infrastructure and regulatory environment have difficulty keeping pace.
  • Positive results for Ritherdon’s roadside cabinet
    April 9, 2014
    The latest roadside cabinet developed by Ritherdon is said by the company to be the world’s first passive roadside cabinet. To ensure that the product performed as specified in EN 12767, two full-scale crash-tests were carried out on the product. The tests examine two parameters to define the safety level of the vehicle occupants at the time of impact: acceleration severity index (ASI) and theoretical head impact velocity (THIV). The car was crashed into the passively safe cabinet at 35km/h and 100 km
