WX03-Spot Weather Impact Warning
Status: Existing
Description
This service package will alert drivers and other travelers to unsafe conditions or road closure at specific points on the downstream roadway as a result of weather–related impacts, which include, but are not limited to high winds, flood conditions, ice, fog, dust storms, snow drifts, avalanches, and rock falls. The service packages is designed to use standalone weather and advisory systems to warn drivers and other travelers about inclement weather conditions that may impact travel conditions. Real time weather information is collected from fixed environmental sensor stations, vehicle based sensors, weather services and advisory systems. The information is processed to determine the nature of the alert or warning to be delivered and then communicated to connected vehicles and personal devices. If the warning includes road closure then diversion information can be provided. For non–equipped vehicles the alerts or warnings will be provided via roadway signage. In addition, the roadway equipment may calculate the appropriate speed for current weather conditions and provide this information to the connected vehicle or on roadway signage.
