Research in Transportation Safety aims to address issues related to multiple modes as well as the needs of a variety of roadway users. Both descriptive- (understanding traveler behavior) and predictive- (making quantitative projections for project evaluations) studies are undertaken. The studies employ state-of-the-art econometric methods and spatial-analysis techniques. Efforts are also undertaken to develop and implement protocols to assist small agencies identify and address their local safety problems.


  • Quantitative methods for crash prediction and injury-severity assessment: Selected projects include development of Florida-specific calibration factors for safety performance functions from the Highway Safety Manual, development of safety performance functions for facilities with managed lanes, and models for predicting injury severity in large-truck crashes.
  • Safety of vulnerable populations: Selected studies include the development of models for pedestrian safety, assessment of safe-routes to school programs, modeling evacuation patters, and understanding the behavior of Florida tourists under hurricane threats.
  • Spatial analysis methods: Selected projects include the development of Geographic Information Systems (GIS) based tools (the SignalFour Analytics) for spatial analysis of crash data; Use of spatial statistics methods for safety analysis
  • Traveler behavior: Selected studies include the understanding the evacuation decisions of tourists under hurricane threats and understanding the speeding behavior of drivers in enhanced penalty zones.
