疏散是一种有效和普遍采取的战略,以尽量减少死亡和受伤的到来飓风。几十年来,跨学科的研究有助于更好地理解疏散行为。疏散目的地选择建模是飓风疏散交通规划的重要环节。疏散目的地的选择与多种因素有关,其中长期的社会因素被认为是必不可少的,但由于数据收集的困难,在大多数研究中被忽视了。本研究利用从Twitter上检索的长期人员移动记录,以(1)加强社会因素在疏散目的地选择中的重要性,(2)量化个人层面的熟悉度测量及其与个人目的地选择的关系,(3)开发一种用于汇总县级社会距离测量的大数据方法,以及(4)论证了如何通过将社会距离和物理距离都包括在内来改进引力模型用于疏散目的地选择建模。
Evacuation is an effective and commonly taken strategy to minimize death and injuries from an incoming hurricane. For decades, interdisciplinary research has contributed to a better understanding of evacuation behavior. Evacuation destination choice modeling is an essential step for hurricane evacuation transportation planning. Multiple factors are identified associated with evacuation destination choices, in which long-term social factors have been found essential, yet neglected, in most studies due to difficulty in data collection. This study utilized long-term human movement records retrieved from Twitter to (1) reinforce the importance of social factors in evacuation destination choices, (2) quantify individual-level familiarity measurement and its relationship with an individual’s destination choice, (3) develop a big data approach for aggregated county-level social distance measurement, and (4) demonstrate how gravity models can be improved by including both social distance and physical distance for evacuation destination choice modeling.
