In the aftermath of a hurricane, local emergency managers need to communicate reentry plans to households that might be scattered over multiple counties or states. To better understand evacuees’ households’ reliance on different information sources at the time they decided to return home, this study collected data on reentry after Hurricane Ike. The results from a survey of 340 evacuating households indicated that there was low compliance with official reentry plans and that none of the information sources produced greater compliance with official reentry plans. Nonetheless, there were significant changes in the utilization of different sources of emergency information over the course of an evacuation but local news media remained the most common sources throughout the event. There also were significant differences in the relative importance of different sources of reentry information, with people relying most on information from peers. In summary, local authorities need to identify more effective ways to communicate with evacuees that have relocated to distant communities and to motivate them to comply with official reentry plans. 相似文献

Managing evacuees’ reentry into their communities after an evacuation can be a major challenge for emergency managers, especially in instances when evacuees return before the official all-clear message. Despite the frequency of post-evacuation reentry into evacuated areas, there have been few studies of this process and the issues returnees expect and experience during the return phase. A survey of evacuees after Hurricane Ike indicates that household compliance with reentry plans was low, with only a minority of returnees (38 %) complying with official reentry plans. An examination of reentry concerns shows that minority ethnicity, lower education, and lower income were associated with higher levels of reentry concerns and, to a lesser extent, with problems experienced after returning. Results also indicate that none of the demographic variables correlated significantly with compliance with official reentry plans and only higher income predicted later entry. However, concerns about reentry traffic predicted earlier reentry and concern about physical risk was related to reentry plan compliance. This study provides insight into the concerns that motivate households’ reentry decisions and can inform the creation of return strategies that account for people’s concerns about their hurricane-impacted communities. 相似文献

Residential development in fire-prone areas of the western United States is a growing concern. The steady addition of homes to this region places more people and property at risk each year. In many areas housing is increasing without commensurate improvements in the road network, particularly in regards to the number, capacity and arrangement of community exit roads. This results in steadily increasing minimum evacuation times, as each additional household contributes to potential evacuation travel-demand in a wildfire. The goal of this research is to perform a comprehensive geographic search of the western U.S. for communities in wildfire-prone areas that may represent difficult evacuations due to constrained egress. The problem is formulated as a spatial search for fire-prone communities with a high ratio of households-to-exits and solved using methods in spatial optimization and geographic information systems (GIS). The results reveal an initial inventory and ranking of the most difficult wildfire evacuations in the West. These communities share a unique vulnerability in that all residents may not be able to evacuate in scenarios with short warning time. For this reason they represent prime candidates for emergency planning, and monitoring their development is a growing need. 相似文献
