§Testbed specifications
□The hurricane Katrina

LSU
□About 400,000 evacuees
over a 48 hour period
▪96% auto-based and 4%
assisted transit
evacuations
□Evacuation destinations,
departure times and mode shares are derived from observed data collected
during the Katrina evacuation
□
§Modeling Tool: TRANSIMS
□An open-source dynamic
transportation modeling tool developed
and maintained by AECOM for FHWA
▪Dynamic routing of
individual travelers and 48 hour regional simulations
▪Randomly select
travelers to receive and act on EVAC information
▪Vehicle trajectories, traveler
plans, disaggregate travel times and flow rates
▪Outputs can be
visualized in geospatial packages such as ArcGIS
