Summary Information

In Oregon, two automated wind warning systems were installed, one at a bridge and another on a roadway segment, to detect high cross winds. The system was designed to warn drivers to pull-over and wait until conditions improved or take an alternate route. The two systems had similar components. Wind gauges (anemometers) were connected to roadside static message signs. Flashers where activated when average wind speeds reached predetermined threshold levels. The system automatically recorded the severity of the cross winds. The system automatically used dial-up phone service to notify traffic operators of system status. Once wind conditions were verified by the Traffic Operations Center, additional warnings were posted on the Oregon DOT TripChek Web site. The warning messages were deactivated when wind speeds dropped below threshold levels.

The cost of each system was approximately $90,000. Annual O&M estimates ranged between $3,000 and $3,500.
