Natual disaters such as earthquake and flooding result in massive damages to not only human fatalities but also buildings, houses, and road infrastructure. the natural disasters are still ongoing worldwide, and the damages are still severe despite the advance of disaster countermeasures. Particularly, earthquake results in massive fatalities and property damages because forecasting earthquake in advance is barely possible. in 2016, frequent earthquakes concentrated frequently occurred in the Byeongsangbuk province, and the maximum magnitude recorded 5.8-scale. Although the impact of this earthquake on fatalities and infrasturucture was not severe, the concern that wors earthquake is likely to happen exits because the frequent earthquakes in the Gyeongsangbuk province prove that the faults in tish region is still active. In response to earthquakes, many govermental organizations in charge of relief and evacuation have developed plans and manuals, but the roles of transportation and traffic management are especially important because this can contribute evacuation of people and resilience from damages. This more likely in a severe condition, in which the residents need to be evacuated.

This research proposed an evacuation traffic management strategy using public transits (i.e., buses), which could be managed by govermental bodies in an emergency situation regarding that many bus companies are being public-finsnced in part. To this end, this research established principles i) to select evacuation routes that are resistant to earthquake, ii) to appoint bases of evacuation, and iii) to utilize bus fleets in evacuation. In addition, a quantitative analysis was conducted using a case-study in a City of Gyeongju, in oder to investigate and prove the effectiveness of the proposed evacuation traffic management strategies. Therefore, the time required for evacuations using public beses and passenger vehicles, the numver of buses required for the evacuation demand, and an optimum mode share of buses and passenger vehicles were investigated. In addition, future studies and recommendations for a comprehensive evacuation traffic menagement strategy were provided after concluding statements.

This study is to mitigare the damages of natural disasters by providing the traffic management strategies, and investigated the measures to evacuate residents from the impacted areas to safe areas.
It is expected that the strategies and the quantitative analysis results provided by this research will be of helf to enhance the evacuation plan when natural disasters occur.
