Marwis mobile road sensor on display by Lufft

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."

    New trials show Bluetooth and Wi-Fi signals can be reliably used for measuring travel times and at a lower cost than an ANPR system, but which is the better proposition depends on many factors. Measuring travel times has traditionally relied automatic number plate (or licence plate) recognition (ANPR/ALPR) cameras capturing the progress of vehicles travelling along a pre-defined route. Such systems also have the benefit of being able to count passing traffic and have become a vital tool in dealing with c

    A common assumption, even amongst informed observers, is that there’s but a handful of urban charging schemes in operation around the world and scant prospect of that changing any time soon. Larger city-sized schemes such as Singapore, London and Stockholm come readily to mind but if we take a wider view and also consider urban access control and Low Emission Zones (LEZs) then the picture changes rather radically. There is a notable concentration of such schemes in Europe but worldwide the number is comfort

    Richard Cuerden considers measures to improve the safety of vulnerable road users. The competitive nature of the car market has seen an increase in protection for those travelling inside the vehicle and this is reflected in the casualty statistics -but the same does not apply to those outside the vehicle. And with current societal trends such as ageing populations, an increasing number of pedestrians and cyclists encouraged by environmental policies, this is an area that authorities such as the European Uni
