There is concern regarding the safetyof personnel working in gore areas to replace these signs, and the resources necessary for continualmaintenance. The objective of this project was to identify and evaluate alternative methods that may reducethe number of sign hits. Researchers visited several sites with safety problems related to frequent sign hits,determined factors that contribute to sign crashes, and recommended potential treatments. They also evaluatedthe impact of eliminating exit gore signs at locations where appropriate advance warning with overhead exitsigns are provided. Field studies were conducted at two freeway exits in Corpus Christi, Texas. It was foundthat the lack of exit gore signs at the two freeway exits did not have any negative consequences in terms ofvehicle speeds, deceleration behavior, and erratic maneuvers
