Abstract
  • A right-hook crash is a bicycle-motor vehicle crash between a right-turning motor vehicle and an adjacent through-moving bicycle. This study focuses on right-hook crashes that occur during the latter stage of the circular green indication at signalized intersections with shared right-turn and through lanes. The overall objective was to evaluate and identify engineering treatments that are effective in reducing the frequency and severity of right-hook crashes. The areas of engineering treatments that were considered are as follows: signage, pavement markings, curb radii, and protected intersections. The driver performance measures include visual attention, crash avoidance, and potential crash severity. The resulting analysis suggests that while these various driver performance metrics can be measured robustly, and all of the treatments had some positive effect on measured driver performance, it is not yet clear how to map the magnitudes of the differences to expected crash outcomes. Additional work is recommended to address the limitations of this study and to further consider the potential effects of the right-hook crash mitigation strategies from this research.
