This report describes the research that was conducted under Transportation Pooled Fund (TPF) study TPF-5(361): SHRP2 Naturalistic Driving Study Pooled Fund: Advancing Implementable Solutions (NCHRP 2023), for which the goal is to develop novel, multidisciplinary solutions based on recorded natural behavior of vehicle operators interacting with infrastructure and other vehicles. The research demonstrates that including speed crash modification factors (CMFs) can improve crash prediction precision for certain facility types. The speed CMF development approach used in this study can be used to develop speed CMFs at the jurisdiction level, if required data are available.


This research will be of interest to roadway designers, safety professionals, and others with an interest in speed management.
