This report provides practitioners and other stakeholders with a resource that identifies and describes current capabilities, best practices, and future data and analysis needs for quantifying the safety-performance effects of multiple safety treatments that agencies implement simultaneously during the conversion of typical streets to Complete Streets. The recommendations include future research needs for data-driven safety analysis (DDSA) and future directions related to the potential use of other performance metrics that could provide additional insights into Complete Streets benefits, including broader public health benefits. The report includes three appendices that detail Complete Streets treatments, methods to develop crash modification factors (CMFs) for treatment combinations, and five case studies that illustrate the analysis methods and inform the content of the primer in chapter 4.
