Abstract

Evacuees' behaviors have a significant impact on evacuation efficiency. Evacuation clearance time is one of the key indicators in the evacuation planning and management. Evacuees' departure time choice, destination choice and route choice behavior based on real-time traffic information are three crucial factors used to estimate evacuation clearance time. In this paper, we use the orthogonal experimental design method to determine values of these three factors simultaneously, which can reduce evacuation clearance time significantly. Once we obtain these values, we can guide evacuees' departure time choice, destination choice and route choice behavior to approximate these values and evacuation efficiency will improve greatly. The dynamic traffic evacuation process is modeled using a rule-based multi-agent microscopic traffic simulation system called TransWorld. The simulation experiment results illustrate the effectiveness and reliability of the proposed method. The proposed methodology, computational results and discussions can be used for future emergency evacuation planning and management.

基于正交试验设计方法的应急交通疏散控制

疏散人员的行为对疏散效率有显著影响。疏散间隙时间是疏散规划和管理的关键指标之一。基于实时交通信息的疏散人员出发时间选择、目的地选择和路径选择行为是估算疏散间隙时间的三个关键因素。本文采用正交试验设计方法，同时确定这三个因素的取值，可以显著缩短疏散间隙时间。一旦得到这些值，就可以指导疏散人员的出发时间选择、目的地选择和路线选择行为接近这些值，疏散效率将大大提高。采用基于规则的多智能体微观交通仿真系统TransWorld对动态交通疏散过程进行建模。仿真实验结果验证了该方法的有效性和可靠性。所提出的方法、计算结果和讨论可用于未来的紧急疏散规划和管理。
