| 摘要： | The researchers evaluated 20 years of Texas nighttime rainfall data. From this review, they determined representative rainfall rates for the state and built a 1600-ft rain range capable of uniformly reproducing representative rainfall rates. The researchers then obtained pavement marking samples from a variety of sources and measured retrorefl ectivity under dry and wet conditions. Research participants were recruited to drive an instrumented vehicle through the rain range. Their task was to identify isolated skip lines randomly placed throughout the length of the rain range. The researchers measured the distances at which the research participants identifi ed the pavement markings. Analyses of these distances included correlations with the dry and wet retroreflectivity measurements. / Supplementary Notes: See also PB2006-102429 and PB2008-100136.
