Mapping the 2003 Southern California Wildfire Evacuations

本项目的目的是设计一个2003年南加州野火疏散的地理数据库。主要的研究问题是，“野火疏散发生在何时何地，他们的一般特征是什么？”我们感兴趣的示例特征包括：发现事件（野火）的时间、疏散命令的时间、介质和内容、疏散的区域以及导致给定保护行动的决策过程。该项目将分为两个阶段：1)信息收集和2)地理数据库设计。第一阶段将集中收集文章、照片、视频、目击者陈述等形式的信息。其他要收集的次要数据包括航空照片、卫星图像、土地所有权和道路。将对应急管理人员（举报人）进行结构化访谈，以收集有关每次疏散和导致特定保护行动的决策过程（例如强制疏散与自愿疏散）的更详细信息。第二阶段的重点将是把这些资料汇编成一个全面的地理数据库。该项目将：1)增加我们对野火疏散和重大事件相关决策的复杂空间动态的理解；2)为未来的预警和疏散行为研究提供样本框架；3)为其他面临野火风险的社区提供更好的疏散建模和预测。

The objective of this project is to design a geographic database of the Southern California wildfire evacuations of 2003. The primary research question is, "Where and when did wildfire evacuations occur and what were their general characteristics?" Example characteristics of interest include the time the event (wildfire) was detected, the timing, medium, and content of the evacuation order, the area that was evacuated and the decision-making process that led to the given protective action. The project will be divided into two phases: 1) information gathering, and 2) geographic database design. The first phase will focus on collecting information from in the form of articles, photos, video, and eye-witness accounts. Other secondary data to be collected include air photos, satellite imagery, land ownership, and roads. Structured interviews of emergency managers (informants) will be conducted to gather more detailed information on each of the evacuations and the decision-making process that led to a particular protective action (e.g. mandatory versus voluntary evacuation). The focus of the second phase will be assembling the information into a comprehensive geographic database.This project will: 1) increase our understanding of the complex spatial dynamics of wildfire evacuations and associated decision making for a major event, 2) provide a sampling frame for future behavioral studies on warning and evacuation, and 3) lead to better evacuation modeling and prediction for other communities at risk to wildfire.
