This study uses a small regional road network as an example to introduce the recent development in the seismic impact assessment of a road network (ROSA). ROSA is utilized to evaluate the impact on the traffic between two areas when part of the road network is damaged and the road is blocked due to an earthquake. Since roads not only maintain human daily life and economic activities but also play an important role in emergency rescue and evacuation, it is important to evaluate the seismic retrofits of road networks. Furthermore, through ROSA, the risk of seismic blockage of road components and the impact of regional traffic can be identified; consequently, ROSA offers strategies and helps in pre-earthquake disaster prevention planning for the road network. |
