  1. Highway Design and Traffic Control for Hurricane Evacuation LSU HURRICANE CENTER Aspects of Current Design Plans Brian Wolshon Dept. of Civil and Env. Engineering Addressing Hurricanes and Other Hazards and Their Impacts On the Natural, Built and Human Environments

  2. Initiation & Termination Designs • The location and configuration of initiation points are based on local concerns and existing road network, geography, and terrain. • Median cross-over • Interchange ramp connections LSU HURRICANE CENTER • Termination designs also vary. Although, typically, the goal is not to merge the traffic streams. • Permanent split • “Bleed-off” and merge • Exit “normal” flow & x-over contraflow • Exit contraflow and re-route

  15. Design Plans Features LSU HURRICANE CENTER

  16. Alabama DOT I-65Typical Interchange Off-Ramp Reentry to Contraflow Lanes All On-Ramps open for exiting “Flip Down” Contraflow Guidance Signs

  17. Georgia DOT I-16Typical Interchange(without on-ramp exiting) No Off-Ramp Reentry to Contraflow Lanes On and Off-Ramps closed using Type III Barricades

  18. With On-Ramp Exiting No Off-Ramp Reentry to Contraflow Lanes On and Off-Ramps Closed Using Water Filled Barricades

  19. Florida DOT I-4Typical Interchange No On-Ramp Exiting or Off-Ramp Reentry from/to Contraflow Lanes
