Abstract:University of Florida researchers developed a revised barge impact probability expression applicable for the design of bridge structures located on Florida waterways. University of Florida researchers obtained barge flotilla traffic data and barge-to-bridge collision data for Florida bridge locations. Using these data, they were able to calculate historical barge-to-bridge collision rates and probabilities. The Florida-specific probabilities were used with additional information from the AASHTO procedures to work backwards and calculate base aberrancy rates for each bridge location for which data had been obtained. A subset of these rates was selected to produce a single value that can be used in the design process for risk assessments for new and existing bridge structures in Florida.
