Abstract

"The road to finding a shoulder rumble strip design that accommodates bicyclists and motorists alike has been bumpy. The benefit of rumble strips for preventing run-offthe- road crashes has been clearly proven in the literature. Rumble strips that are wide, deep and close to the traveled way - but not so close that they are routinely hit - provide the most effective warning signal to motorists. Alternatively, rumble strips that are thin, shallow and that provide the greatest amount of smooth shoulder space are safest for bicyclists.

Bicyclists require a clear width of approximately four feet (five feet beside guardrail) to ride safely. This clear width can be reduced by accumulation of debris on the shoulder. The distance from rumble strips to the point on the shoulder at which debris accumulation begins is a key variable in this dichotomous situation. This research attempts to quantify this clear width and relate it to the conditions of the adjacent roadway.

This thesis examines the relationship between debris offset and surrounding conditions, such as pavement condition, and traffic volumes"--Abstract, page iii.
