Study on Rapid Assessment of Traffic Capacity of Girder Bridges Post Major Earthquake

Abstract: To provide a highly applicable tool, which can assess the damage level and traffic capacity of girder bridges accurately and quickly, we proposed a new rapid assessment model for girder bridges, which contains a vulnerability model with parameter modification and a fast evaluation method for traffic capacity. Based on this model, we developed a rapid assessment software for girder bridges, using Visual C++ and ArcGIS Engine, in which the damage level and traffic capacity of girder bridges post-quake can be hig… Show more

“…Current studies on free-flow and queue discharge rates have focused on smaller time scales and specific situations, such as Zhang Xirui, Fang Zhixiang, Li Qingquan et al analyzed the spatial and temporal characteristics of urban road capacity based on floating data [ 26 ], Fu Chenghong, Gao Liangpeng, Zhong Ying et al analyzed the capacity of expressway tunnel sections under lane reduction scenarios [ 27 ], Feng Biao et al conducted a study on post-earthquake bridge capacity [ 28 ], Yipeng Ye et al conducted a study on the capacity of freight roads [ 29 ]. In summary the aim of this paper is to find patterns of change in road capacity (free flow capacity, queue discharge rates) over medium to long term time scales.To undertake a more robust and comprehensive analysis of free flow capacity and queue discharge rates over a medium to long term time horizon, the investigation delineated in this paper unfolds in two pivotal steps.…”
