This paper investigates the dynamics of single-vehicle motorcycle crashes that occur on curves and identifies rider actions that contribute to causing these crashes. Physical evidence and physical principles that would enable a reconstructionist to determine when these actions are present in a particular crash are identified. The investigation is carried out by analyzing video footage of 10 motorcycle crashes that all occurred on a particular curve (Edwards Corner) on a section of the Mulholland Highway called “The Snake.” This section of highway is located in the Santa Monica Mountains of California. All of the video footage of these crashes was captured by a videographer who regularly takes video of motorcyclists traversing this curve and posts crash videos on YouTube. To aid evaluation of these crashes, the authors mapped Edwards Corner using both a Sokkia total station and a Faro laser scanner. This mapping data enable analysis of the videos to determine the initial speed of each motorcycle, to identify where in the curve particular rider actions occurred, and to characterize the roadway radius and superelevation throughout the curve. For each crash video, this paper reports quantitative data from the crash along with a qualitative description of the rider’s actions.
