"To coordinate a hurricane response, emergency managers have to rely on locally-drafted evacuation plans and guidelines provided by the Federal Emergency Management Agency (FEMA). After the chaotic and poorly planned evacuations carried out during the 2005 hurricane season, new planning procedures were introduced. FEMA also now uses a computer model to estimate how long it will take to clear a city based on its population, although this model can't advise on when and how best to evacuate it."
"A researcher at MIT is now testing software that combines an unprecedented amount of data to help emergency managers make faster, more informed decisions. "
"The software is also flexible, allowing emergency managers to input their city's demographics and geography. And it adopts a novel approach, categorizing a city's population into different demographics, such as the elderly, tourists, hospital patients, and families with children, for separate evacuation. In addition, says Metzger, the model considers details of available evacuation routes. For example, as there is only one highway that leads out of Key West, FL, emergency managers would need to phase out evacuations to avoid congestion. This allows the software to provide more finely tuned recommendations, he says. The software can even advise emergency managers when to start bringing in supplies, where to set up shelter locations, and when to call in the National Guard."
