Researchers Say: More Bicyclists Increases Safety

By - August 18, 2014

University of Colorado – Denver researchers recently published a paper developing a methodology for estimating bicycle collisions in an intersection.  Traffic engineers use safety performance functions (SFPs) to predict and estimate collisions, but their formula does not take into account bicycle usage to predict the risk to bicyclists.  The intent of the paper was to develop and demonstrate the suitability a similar safety performance function for bicyclists.  In testing the methodology for creating a model in Boulder, Colorado they found that intersections with more cyclists had fewer per cyclist collisions, suggesting that there is safety in numbers.  The model is unique to Boulder, Colorado but other areas should use the method to create their own safety performance function.
