VARIABLE MESSAGE FOG HAZARD WARNING SIGNS TO CONTROL VEHICLE OPERATING CHARACTERISTICS

The objective of this research project was to determine the effectiveness of a variable message fog warning sign system on a 6.5 mile fog prone section of Interstate 5 in Oregon. Prior to installing this variable message sign system in 1968, an intensive literature search was conducted to determine the optimum signing system for our needs. It was determined that prior experience with this type of system had not been adequately documented. Therefore, the "Oregon Design" was developed, and this study conducted to determine the system's effectiveness. The primary finding of this study was that the "Oregon Design" variable message fog warning sign system has been effective in reducing the number of fog related accidents on this section of highway.
