| 摘要： | The term litter is generally defined as misplaced solid waste, although different jurisdictions have their own definitions. Regardless of the definition used, litter has been a persistent problem in the United States since at least 1953 when Keep America Beautiful (KAB), a nationwide nonprofit organization, was formed with a mandate of litter prevention. As the number of vehicle-miles of travel increases, so too does the potential for roadside litter. At present, roadside litter appears to be omnipresent. The impacts of roadside litter and litter collection are staggering. The estimated cost of collecting roadside litter exceeds $130 million per year by state highways alone, and approaches $500 million by all levels of government. These figures are fairly dated at this time, as evidenced by the Georgia Department of Transportation (DOT), which reported $14 million spent on litter collection in 2006, and a trend of increasing costs at a rate of 20%per year. |
