In the aim of reducing the impacts of urgent disasters on people’s life, health and property jointly, rescue vehicles need to be sent to the risk zones and the affected population should be evacuated from the risk zones. The rescue traffic and the evacuation traffic interact with each other and have conflict directions. And the conflicts are dynamic with the changes of rescue routes if adopting different rescue entrance opening plans. The rescue traffic has priority and thus it is necessary to study the impacts of rescue traffic on the evacuation traffic organization. In this paper, a two-staged optimization method for evacuation and rescue traffic organization is proposed. For the rescue traffic, different rescue entrance opening plans are considered. Numerical studies are carried out on an empirical network. And the proposed method is compared with two existing shortest-path-based rescue traffic organization methods. The results show that the rescue traffic with different rescue entrances opening plans affect the evacuation traffic organization dynamically, and the evacuation effectiveness and the rescue effectiveness can be balanced by adjusting the number of open rescue entrances.

为了共同减少紧急灾害对人们的生命，健康和财产的影响，需要将救援车辆运送到危险区域，并将受影响的人群从危险区域撤离。救援交通和疏散交通相互影响，并有冲突的方向。如果采用不同的救援口开放计划，冲突会随着救援路线的变化而变化。救援交通是优先事项，因此有必要研究救援交通对疏散交通组织的影响。本文提出了一种疏散与救援交通组织的两阶段优化方法。对于救援交通，考虑不同的救援入口开放计划。数值研究是在经验网络上进行的。将该方法与现有的两种基于最短路径的救援交通组织方法进行了比较。结果表明，不同救援口开放计划的救援交通动态地影响着疏散交通的组织，通过调整敞开的救援口的数量可以平衡疏散效果和救援效果。
