There has been growing interest in minimizing damages by disasters, but the countermeasure in traffic engineering has been limited to the passive researches such as evaluating transportation network. The algorithm suggested by this paper was the active countermeasure to find directly the optimal road sections for investment against catastrophes using the optimization process and the simulation. This was composed of three modules such as scenarios, model, and aggregation. First, scenarios were made by the assumption of unusual behaviors under 'life or death' situation. Second, the object function using the number of dead people and the budget constraint were included into the optimization equation. Then, the results of iterated scenarios were aggregated to the best alternative, using the possibility of disaster occurrence. Lastly, it is applied using the network and production of Ulsan City in South Korea.
