Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a new safety shortest-path routing algorithm to avoid traffic congestion for stochastic road blocks in serious disasters.
In such situation, any roads might be blocked and not passable.
The results of the usual shortest-path routing are unavailable to find the paths and the recomputation must be started again from the blocked point when an agent meet a blockage, because the algorithms do not consider the road blocks.
In addition, traffic congestion occurs when many agents use a same path to evacuate to a refuge.
We, therefore, introduce the Iterative Taxing Framework into a safety shortest-path routing algorithm which is an improved A* algorithm for stochastic road blocks in serious disasters.
We also perform evaluation experiments to confirm that the proposed algorithm can find the paths which are more safe and cause fewer traffic congestion than A* algorithm and Dijkstra's algorithm.
