我们解决的问题，检测在一个大型的道路网络中的关键环节，特别是专注于一个事实，即在允许的时间内的可达性起着重要的作用，在灾难疏散的情况下。为此，我们利用一种称为TBC（时间限制的临界度）的措施，该措施量化了当链接被阻止时，在允许的时间内无法移动到疏散设施的人数。在我们使用静冈县数据进行的计算机模拟中，我们表明具有高等级TBC程度的道路连接可以根据允许的疏散时间而发生实质性变化。然后，我们分析了这些关键环节对无法在允许的时间内转移到疏散设施的人数的影响。
We address the problem of detecting critical links in a large road network, especially focusing on the fact that reachability within a permissible time plays an important role in case of disaster evacuation. To this end, we utilize a measure called TBC (time-bounded criticalness) degree that quantifies the number of people who become unable to move to evacuation facilities within a permissible time when a link is blocked. In our computer simulation using data in Shizuoka Prefecture, we show that the road links having highly ranked TBC degree can substantially change according to the permissible evacuation time. Then, we analyze the influences of these critical links on the numbers of people who become unable to move to evacuation facilities within the permissible time.
