The primary intent is to identify whether it is more common for bicyclist to roll through intersections or to come to a "complete stop," as is required by Washington State Legislature. This is done through the development of a pilot study for observing bicyclists' behaviors, based on a foundation of methodological and theoretical research as well as a review of domestic bicycle traffic accident data. During a three-day count period in November 2014, a pilot study documented bicyclists' stopping behavior, collecting data on a total of 2,616 bicyclists at six count locations. Results from this study find that approximately 55% of all bicyclists used rolling stops and/or track stands, 25% failing to stop and only 19% coming to a complete stop. Perhaps the most significant finding emerging from this research is the lack of truly significant findings. Despite this high degree of non-compliance with the stopping law, no reliable evidence was found exhibiting decreased safety resulting from the use of rolling stops by bicyclists at stop signs.application/pdfen-USCopyright is held by the individual authors.Behavioral Mobility; Bicycle; Observational Reserach; Rolling Stop; Stop SignTransportation planningUrban planningPublic administrationurban planningThesis
