• Abstract:
  In this project, University of Central Florida researchers combined two types of safety analysis, microscopic and macroscopic, to overcome their limitations. Microscopic models focus on traffic flows and related parameters. Macroscopic models are based on analyzing zones in the roadway network; they are more efficient than micro models at integrating zone-level features into crash prediction, but they identify hot zones, not specific hotspots. The researchers’ method combined macroscopic efficiency with microscopic specificity.
