当易扩散性危险品发生严重泄漏后，危害区的应急交通疏散对减少人员伤害和经济损失具有非常重要的作用.本文研究区域易扩散性危险品发生泄漏后，建立在规定的时间内，应急交通部门主导的路网疏散，目标函数为区域应急疏散路网能力的元胞传输模型.结合模型复杂性的特点，以及量子粒子群算法的优点对模型进行求解.算例表明，在应急疏散过程中，应急交通管理部门利用信息优势和主导权利使路网应急疏散能力比自然的路网应急疏散能力提高了56.9%.模型和算法可为应急交通管理决策部门提供理论支持.

Traffic Evacuation of Cellular Network after Dangerous Goods Spill

After dangerous goods spilling,the emergency evacuation transportation of the hazardous area is rather important to reduce personal injuries and economic losses.This paper analyzes the emergency evacuation on major and core road networks during a given time.The objective function is a cell model for regional emergency evacuation considering road network capacity.Then,combining with the complexity of the model characteristics and advantages,the quantum particle swarm model is solved.The example shows that under emergency situations,if the traffic management department makes most of the information superiority and dominant road network evacuation capacity,the evacuation capability will increase by 56.9% than normal cases.The proposed models and algorithms provide a theoretical support for emergency traffic management.
