Reduce Risks, Improve Public Safety, and Save Costs

Adverse weather conditions have a major impact to the traveling public and commerce each year. Heavy rain and flooding, snow and ice, fog, high winds, and more, all have an effect on traffic flow, driving conditions, and public safety.

High Sierra Electronics’ StormLink® Road Weather Information Systems (RWIS) provide real-time information about the weather and roadway conditions. Our expertise in sensing networks enables real-time monitoring and analysis of the environmental variables related to hazardous weather conditions. Continuously updated data is used to help operations and maintenance personnel stay informed about what is happening on the roadway so they can make timely decisions and take proactive measures to reduce the risks and impacts of winter road weather conditions.

24x7 Real-time Monitoring, Reporting, and Alerting on Road Weather Conditions

For the people who need to make decisions, our Road Weather systems provide 24×7 secure access to information and data insights in the AEM Elements 360 software platform via any web-enabled device.
