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."

    Caldecott Tunnel’s new Fourth Bore is utilising a bespoke high-capacity monitoring and communications network from Moxa. The Caldecott Tunnel connects Contra Costa and Alameda counties in Northern California and traditionally it has suffered severe congestion - especially during peak hours. Opened in 1937 as a twin-bore arrangement, by 1964 the increase in traffic volumes led to a third bore being added. Shortly after the third bore was opened a tidal flow was introduced with the centre bore alternating in

Teledyne DALSA product manager Manuel Romero describes 10 key criteria to aid selection of advanced camera technology for safety or security applications. There are many ways in which machine vision systems can enhance safety and security in transportation, but the ultimate results will only be as good as the image produced. Success relies on correct selection of the camera of such systems, as the features and performance required vary

    Drivers crossing Chile’s capital are benefitting from additional investment in ITS. Mauro Nogarin reports. Santiago de Chile is pioneering the development of concession-interoperable, multi-lane, free-flow urban highways. This road network crosses the city from north to south (Autopista Central), from east to west (Costanera Norte) and also includes the north-western (Vespucio Norte) and southern (Vespucio Sur) ring roads surrounding this metropolitan area of seven million people.
