多突发事件耦合情况下路网可达性研究

Study on Accessibility of Road Network under Multi-emergency Coupling Case

定义路网可达性公式,设计Matlab矩阵计算程序计算路网可达性,分析单一事件以及多突发事件耦合对路网可达性的影响。研究结果表明,多突发事件耦合时,对路网可达性的影响程度远大于单一突发事件对路网影响程度的简单加和。

This paper defines the formula to calculator the accessibility of road network,designs the Matlab matrix calculation program to calculate the accessibility of road network,and analyzes the influence of single event and multi-event coupling on the accessibility of road network.The study result shows that the influence of multi-event coupling on the accessibility of road network is much larger than the single event.
