Using an oversampling-based classification method and taking bridge structure movement into account, the accident risk variables of a typical long-span bridge were assessed

Abstract

Nicolas John

Major transportation corridors, including long-span bridges, connecting core cities in coastal areas have played an important role in lowering highway traffic mileages, enhancing city cooperation and exchanges, easing traffic congestion, and supporting regional economic development. However, as traffic volumes and truck proportions increase, the risk of serious accidents on long-span bridges has increased dramatically in China. According to data, the number of traffic accidents on typical long-span bridges in China has increased significantly in recent years. Due to large truck percentages, inclement weather conditions, and especially the physically dynamic bridge structures, which is one of the unique factors of long-span bridges, traffic accidents on long-span bridges have associated specific characteristics when compared to traffic accidents on ordinary highways
