Title: Texas Department of Transportation 2009 Visible Litter Study; Final Report
Summary: NuStats, in cooperation with EnviroMedia Social Marketing and the Texas Department of Transportation (TxDOT), conducted a follow-up to the 2001 and 2005 Visible Litter Study (VLS) in 2009 to estimate the projected number of pieces and types of litter on Texas roadways. For this study, litter was collected from 163 research segments across Texas, each consisting of a 1,000-foot-long stretch of TxDOT-maintained roadway. In 2005, 129 sites consisting of a 750-foot-long stretch of roadway were sampled. Data from the current study were weighted for comparison with those from 2005. The increase in number and length of sites in 2009 was designed to improve the confidence interval for the findings. Although the changes narrowed the interval from +/- 249 million pieces of litter in 2005 to +/- 200 million pieces of litter in 2009, changes in litter counts year to year are not statistically significant.
