Road Weather Information System (RWIS)

Road weather information - knowing exactly what is going on with the roadway, now and in the future - is the key to successful decision making. Combine intelligently designed road weather station, with sophisticated algorithms and smart power management and hosted RoadDSS software solution, giving you a resilient method of display and storage, ensuring access to your information anytime, anywhere. Deploy only what you need to do the job, all without sacrificing accuracy.

Key Benefits

Intelligent, accurate and reliable data
The RWS200 processor contains several sophisticated algorithms that bring in raw data from the pavement sensor, and by using other atmospheric information, creates better calculations of surface conditions. If the final decision making of condition resided in the sensors themselves, accuracy would be compromised in many situations.
Deploy only what you need
Vaisala Road Weather Station RWS200 is completely scalable, allowing you to add the features you need to match the requirements at each location. This scalability does not mean lesser quality components are used, in fact it means that if you need to upgrade a particular site, most everything at the site can remain in use. RoadDSS software suite of road weather decision tools is designed to meet the level of operations in your agency. There are step levels in software experience and operations, so you have the right information quickly and easily available to your decision-makers.
Reliability through on-board interface and power management
One of the main reasons for having an on-site processor is the ability to store historical data if the communication to the network is lost for a long period of time. This ensures that gaps in historical data will be much less likely with local data storage. Smart power management is handled on an individual basis to ensure failure in one component does not disturb other components. Roadside systems are designed to ensure primary data flow and minimize disruption to decision-making.
