This study assesses the effects of zig-zag pavement markings at trail crossings on the W&OD Trail in Virginia. The study found that the markings installed in advance of the two crossings heightened the awareness of both approaching motorists and trail users, and reduced motorist speeds. The study also found that motorists have limited understanding regarding the purpose of the markings, and users of the W&OD Trail and motorists are confused regarding who has the right of way at the crossings.
