Overview

Weather affects all modes of transportation, and Road / Runway Weather Information System (RWIS) technology provides vital information on pavement and weather conditions needed for both highway and airport maintenance operations. RWIS enables maintenance and operations personnel to monitor changing weather conditions in real time and make informed and timely decisions.

An RWIS system can consist of multiple sites, each containing a suite of sensors that gather weather and pavement data and then report to a central location where authorized personnel can view the information. SSI RWIS stations collect atmospheric, pavement surface, sub-surface and video data remotely to provide the most accurate pavement specific weather information available.

Benefits

• Increases safety on roadways and runways
• Removes guesswork about the status of road conditions
• Reduces chemical usage and labor costs
• Critical tool when performing anti-icing
• Necessary data for Maintenance Decision Support System (MDSS)
• Benefit/cost ratios of approximately 5:1 (SHRP-H207)
• Level of service improvement approximately 20% (SHRP-H207)
• Provides data for pavement weather forecasts

Applications

• Departments of Transportation/Ministries of Transportation
• City, County, and Township street maintenance departments
• Airports
