Lufft’s new sensor collects road weather information at traffic speed

Mobile road weather information sensor Marwis, developed by German measurement and control technology company Lufft, can be mounted on any vehicle to collect real-time weather data such as road surface temperature, dew point, water film height, road conditions (humidity, snow, ice and frost) and grip (friction) as well as other environmental data. Marwis measures meteorological data and road condition information 100 times per second. At a driving speed of 80km/h, the mobile sensor records every 20cm, r

Mobile road weather information sensor Marwis, developed by German measurement and control technology company 6478 Lufft, can be mounted on any vehicle to collect real-time weather data such as road surface temperature, dew point, water film height, road conditions (humidity, snow, ice and frost) and grip (friction) as well as other environmental data.

Marwis measures meteorological data and road condition information 100 times per second.  At a driving speed of 80km/h, the mobile sensor records every 20cm, regardless of the condition of the road surface.

The data can be sent via Bluetooth to Lufft’s Smartview software for evaluation.

    Vaisala says it’s time to take road weather seriously
    “It is time to take road weather seriously,” is how Vaisala’s Danny Johns puts the company’s message to this week’s ITS World Congress delegates, and the wider world. While the monitoring of winter weather is well established, wind, rain and poor visibility can occur at any time of the year and have significant impacts on traffic flows and crash statistics. “We are now mapping road networks to identify weather-sensitive areas to best locate road weather stations – it doesn’t take a lot of rain or wind to

    Bluetooth and Wi-Fi offer new options for travel time measurements
    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

    Impact of speed limits in Barcelona
    When Barcelona imposed an 80km/h (50mph), the result was significant in environmental, accident, fatality and injury terms. The 80km/h speed limit had the same positive environmental effect as if 22,100 cars were eliminated from the roads in the metropolitan area. Moreover, a reduction in the consumption of fuel by more than 24,000 tonnes per year was also achieved, while accidents, fatalities and injuries also showed substantial improvement.
