摘要：	Highway structures are public works facilities that are inherently accessible, to a certain degree, to the general public at all hours of the day and every day of the year. As a result, some highway structures are susceptible to graffiti. Graffiti on highway structures is a significant problem thoughout the United States. Not only is graffiti an eyesore to the traveling public, it presents a hazard to the perpetrator and a liability exposure for transportation agencies because highway structures span high elevations and are in close proximity to motor vehicle traffic. The most common methods for combating graffiti include washing the surface of the structure with high-pressure water sprays, repainting the surface, and sandblasting. Although each of these methods can, in most cases, effectively remove the graffiti, the solution is often temporary; more graffiti is likely to appear in the future at the same site. Further, these measures can be quite costly, especially if they have to be repeated on numerous occasions to remove recurring graffiti. Results of a comprehehsive survey of transportation agencies are presented and analyzed. The survey was designed to assess the nature and extent of the graffiti problem as well as to identify some solutions to the problem and identify various preventive as well as removal techniques. The study focuses on current graffiti prevention and removal policies and various other graffiti-removal techniques that are undertaken by different state departments of transportation to mitigate graffiti problems in their states.
