Here in Germany the days are getting colder and the winter services is already on alert – a good time to think about monitoring the road weather as seamlessly as possible! In the following you find facts and figures on road safety and some recommendations of measurement systems that provide efficient and almost gapless information.
Launched in 2008, the NIRS31 was Lufft’s first non-contact road weather sensor that allows easy installation without road closures and costly construction work. It is therefore particularly suitable for the use on bridges where the installation of embedded ground probes entails structural risks. As bridges are usually exposed to stronger winds and the cooling and evaporation of the underlying water it makes sense to monitor them thoroughly.
The NIRS31 was also the base for the development of the mobile sensor MARWIS and the latest stationary sensor with a lower installation height StaRWIS. Reason enough to dedicate this contribution to this sensor – with the best references!
Our Mexican Partner Ingeniería Geofísica y Sistema S.A. de C.V. (IGS) recently won a project of the Communication and Transport Secretary (SCT) as a final client to upgrade and install new Intelligent transportation systems (ITS) along the Federal Bridges and Highways in Querétaro in Mexico. They include eight Automatic Weather Road Weather Information Stations (RWIS) delivering road status, temperatures, friction and others.
