Abstract:

Multiple violent earthquakes have occurred in the past decade. The reliability of post-earthquake urban roadway networks has attracted the attention of engineers and researchers. Since a post-earthquake urban roadway network is a large-scale complex system, the reliability of the roadway network cannot be easily determined by a traditional serial or parallel system, or even a combination of the two. The primary challenge for solving this problem is determining how to integrate the relative importance or weight of each roadway section in the restoration of a post-earthquake urban roadway network. This paper proposes an Edge-Betweenness centrality based model to incorporate the relative importance of roadway sections into the prioritization of post-earthquake urban roadway networks for restoration. The weight model is used to support the resource allocation for restoring a post-earthquake urban roadway network. An assessment system of the post-earthquake urban roadway network based on geography information system (GIS) was developed to implement the proposed model. The roadway network in the city of Shijiazhuang, China, composed of 699 valid sections and 5,705 valid buildings, was employed to validate this model. The results show that the proposed model has the potential of not only obtaining the weight of each roadway section of a large-scale roadway network, but also of conducting the resource allocation for restoring the post-earthquake urban roadway network.
