One challenge facing rural travelers is the presence of weather hazards that produce adverse driving conditions at isolated locations. One such hazard is sustained high winds that can cause high-profile vehicles such as recreational vehicles, commercial vehicles, etc. to overturn, and lower-profile vehicles to leave their lanes, jeopardizing motorist safety. Since wind conditions and patterns are defined significantly by local topography, there is limited ability to mitigate the impacts of wind through improved roadway design. Warning drivers of impending cross winds well in advance and implementing measures to reduce operational speeds are other options explored by transportation professionals. To address localized high cross wind challenges, the Oregon and California Departments of Transportation (ODOT and Caltrans, respectively) have used intelligent transportation systems (ITS) installations to alert motorists of dangerously windy conditions automatically. The warning messages are displayed to drivers at locations where they can stop and wait until the winds die down or where they can decide to take a longer alternate route.
