Weather events have a significant impact on our transportation network. Motorist safety can be jeopardized if roadways are not maintained in the most efficient method possible or if motorists are uninformed about roadway conditions. Mobility can be impacted by weather-related incidents, and weather conditions may slow traffic resulting in lower operational levels of services. Additionally, weather can impact the productivity of public agencies and private business resulting in additional burdens. One way to address these weather impacts is through roadway weather management practices as well as other operational strategies to advise agencies and motorist, control/regulate roadway conditions, and treat roadways efficiently. All of these strategies rely on gathering information, processing data quickly and efficiently, and disseminating that information to stakeholders in a format that support their needs. Roadway Weather Information Systems (RWIS) may provide situational awareness of roadway weather conditions that when combined with other information and decision making tools would allow decision makers to implement the appropriate advisory, control and/or treatment strategy.
