Determining the Safety Impacts of Bicycling and Walking Investments

December 11, 2017


To improve safety for pedestrians and bicyclists, transportation professionals typically look to a toolbox of countermeasures that are proven to reduce crashes. Determining the safety effectiveness of a countermeasure, however, is a complex process. During this webinar, researchers from the UNC Highway Safety Research Center discussed the value of crash modification factors (CMFs), which quantify a countermeasure’s ability to reduce crashes involving bicyclists and pedestrians. Panelists will explore methods for conducting high quality safety evaluation and provide tips for determining the effects of safety improvements.
