Assessing Traffic Flow and Motorcyclist Safety Outcomes Associated with Lane Filtering (BTS-50)
The objectives of this research are to document the existing state of knowledge regarding the impact safety outcomes associated with motorcycle lane splitting and lane filtering, support the development of standardized, behaviorally grounded definitions, and develop an evidence-based toolkit for use by state highway safety offices, state driver licensing agencies, and state motorcycle safety programs to manage the behavioral and safety complexities of motorcycle lane splitting and filtering.
