Simulation and Analysis of Freeway Lane Reversal for Coastal Hurricane Evacuation

The North Carolina Department of Transportation (NCDOT) and Department of Crime Control jointly developed an Interstate 40 lane reversal plan following the unprecedented 1999 Hurricane Floyd multistate evacuation to facilitate resident and tourist evacuation in southeastern North Carolina. The NCDOT sponsored two-year research to address areas of operational concern prior to the 2003 hurricane season. Modifications to the original lane reversal plan resulted from the first year research findings, while the second year's showed effectiveness in expediting evacuation from the coastal threat zone using the modified reversal plan. A potentially extensive queue formation at the contraflow termination point was revealed through modeling of the entire lane reversal plan. The authors present a project overview with principal research findings and resulting plan modifications. Study conclusions and general emergency evacuation problem recommendations are also highlighted.
