A Roadway Context Classification Approach for Developing Safety Performance Functions and Determining Traffic Operational Effects for Florida Intersections
Developing context-specific safety performance functions for Florida intersections to more accurately predict intersection crashes
This research developed SPFs based on a new context classification system used by the Florida Department of Transportation (FDOT) which categorizes intersections into eight different categories.
