RWIS Lite – Streamlined Road Weather Information Systems
Keeping roads and highways safe is critically important. In addition to autumn’s and winter’s perils, the increase of weather fluctuations and extreme weather events throughout the year pose further challenges to road decision-makers.
Filling the Gaps with Mobile Sensing and RWIS Lite Stations
Ideally, a dense network of road weather monitoring stations reliably provides accurate, hyper-local data. Wherever that is not feasible, be it due to local characteristics or tight budgets, mobile sensing and streamlined Road Weather Information Systems (RWIS) can fill the gaps and ensure availability of essential weather and road surface information.
Individually Tailored Systems for Every Monitoring Challenge
On this page, we will present a growing base of success stories and resources around RWIS Lite installations. Check out tabs below for more information around RWIS Lite, such as blog articles, podcast episodes, and the OTT HydroMet guide on Road Weather Monitoring.
Our team of experienced project engineers and skilled technicians is there to explore individual solutions for your road weather monitoring challenge.

Challenge, Solution, Benefits
- Challenge: Installing a full-blown station as a part of a Road Weather Information System (RWIS) requires many sensors and other technical components, which can be cost prohibitive. As a result, many places are left unmonitored.
- Solution: Using a combination of two, all-in-one sensors from OTT HydroMet can get a large array of data at a fraction of the cost. Typically, this combination includes a non-contact road surface sensor and a compact weather station. The versatile monitoring software ViewMondo rounds off this compact yet powerful package.
- Benefits: Less maintenance, labor, and costs required while still providing the data that they need allows the end customers to maintain their roads. This frees up personnel to tend to other areas where sensor technology may not be prevalent.
