ClearPath Weather Software


ClearPath Weather, a component of the Iteris ClearPath™ family of traffic and weather solutions, is a winter road information service that provides decision makers with an easy-to-use display for effectively managing winter weather road issues before, during, and after weather events.  With a single click of the mouse, maintenance managers are able to view real-time information they need such as looping radar, satellite imagery, and site-specific weather and pavement conditions. Each forecast contains the ideal maintenance action given the current and forecasted weather conditions, an intuitive graphical interface for displaying your information, and a specialized pavement forecast generated by Iteris’ Highway Condition Analysis and Prediction System (HiCAPS™) pavement weather forecasting model.
