论文摘要
交通疏散在挽救灾难中的生命中起着至关重要的作用，例如飓风，野火，洪水，地震等。一种预先评估这些罕见事件的疏散计划的能力，包括确定交通流量瓶颈，改善交通管理政策，并了解交通管理政策的稳健性对紧急管理至关重要。鉴于此类事件的稀有性和相应的实际数据缺乏，流量模拟为这种情况提供了一种灵活而通用的方法，此外，还可以与模拟疏散进行动态互动。在本文中，我们建立了一条交通模拟管道来探索上述问题，涵盖了疏散的许多方面，包括地图创建，需求产生，车辆行为，瓶颈识别，交通管理政策改进和结果分析。我们将管道应用于加利福尼亚的两个案例研究。第一个是天堂，该天堂在2018年被大型野火摧毁，并在撤离期间经历了灾难性的交通拥堵。第二个是米尔河谷（Mill Valley），由于该市位于狭窄的山谷以来，米尔河谷（Mill Valley）遇到了野火和潜在交通问题的高风险。
Traffic evacuation plays a critical role in saving lives in devastating disasters such as hurricanes, wildfires, floods, earthquakes, etc. An ability to evaluate evacuation plans in advance for these rare events, including identifying traffic flow bottlenecks, improving traffic management policies, and understanding the robustness of the traffic management policy are critical for emergency management. Given the rareness of such events and the corresponding lack of real data, traffic simulation provides a flexible and versatile approach for such scenarios, and furthermore allows dynamic interaction with the simulated evacuation. In this paper, we build a traffic simulation pipeline to explore the above problems, covering many aspects of evacuation, including map creation, demand generation, vehicle behavior, bottleneck identification, traffic management policy improvement, and results analysis. We apply the pipeline to two case studies in California. The first is Paradise, which was destroyed by a large wildfire in 2018 and experienced catastrophic traffic jams during the evacuation. The second is Mill Valley, which has high risk of wildfire and potential traffic issues since the city is situated in a narrow valley.
