Road and bridge is a common transportation project, which plays a crucial role in alleviating urban traffic congestion. The extensive development of road and bridge projects has greatly reduced the pressure of transportation in our country. In recent ten years, the number of domestic vehicles surged, and the use of road and bridge is also increasing. All of them put forward higher requirements for road and bridge, and the quality and performance of road and bridge have a direct impact on people’s travel safety Sustainable economic development. In the road and bridge design, safety and economy should be the designer to consider the factors. However, safety and economy are often contradictory in the design of road and bridge. In order to improve the safety of road and bridge and reduce the cost as much as possible, the safety and economy of road and bridge should be weighed.
