The Federal Highway Administration created a new weather information tool that more precisely predicts the impact of adverse weather. The Maintenance Decision Support System (MDSS) will allow access to proper weather and road condition information before and during adverse winter weather conditions. The primary goal of the MDSS is to get proper weather, road condition and resource information into the appropriate people’s hands so that they can make proactive decisions to manage highways before and during adverse weather conditions. The benefits include reduced operating expenses and a higher level of service, which result in safer and smoother highway operations and traffic flow. A prototype of the system is available at www.ops.fhwa.dot.gov/weather/MDSSRollOut.htm
