非常规突发事件中的区域路网疏散能力评估与交通组织方案设计

分析非常规突发事件影响下的交通组织特性, 基于元胞传输模型(CTM)设计了疏散目标函数和疏散特性约束, 构造了非常规突发事件影响下限定时间的区域路网疏散能力评估与交通组织设计模型. 针对不同层次的需求, 模型可以整理为完整模型和简化模型两种形式, 在求解计算方面具有不同的特征. 设计了算例(其中包含路网结构和非常规突发事件场景), 应用完整模型和简化模型分别对算例进行了路网疏散能力评估和交通组织方案设计, 评估结论一致, 获取的交通组织方案可行且各具特征. 模型将为疏散预案的设计提供理论支持.

Evacuation capability evaluation and traffic organization planning on the area road network under unconventional emergencies

The characters of traffic organization under unconventional emergencies are studied,and the objective function and constraints for evacuation is designed,then the model for evacuation capability (in limited time) evaluation and traffic organization planning is put forward.The model has two forms: full form and simplified form with different characters.Finally,an example(contains the road network structure and the scenario of unconventional emergency) is presented to illustrate the benefit of this model. It ...
