Dept. of TransportationSrinivasan, SivaramakrishnanUniversity of FloridaUS Transportation CollectionAs traffic volumes increase in Florida, managed lanes are being increasingly used. Managedlanes include those for which multiple passengers (high occupancy vehicle, or HOV, lanes) arerequired or access is permitted based on high occupancy and/or paying a toll (high occupancy/toll or HOT lanes). To date, systematic methods to analyze safety on HOV/HOT lanes in termsof expected crash frequency have not been developed. Crash frequency provides an objectiveview of the safety of an existing roadway, and it can also be used to predict the crashincidence and severity based on roadwaygeometry. This information is useful inplanning and design
