Bridges have played an integral role in the development of economy and progress of human society, which facilitate transportation and promote regional economic development. However, a large number of bridges for sea-crossing or river-crossing have impeded the water transportation to varying degrees, and then one part of bridges are confronted with higher risk of ship-bridge collision. There are many ship-bridge collision accidents in the world in recent decades, which caused huge casualties and property losses. This paper proposes the model of risk degree for ship-bridge collision based on the theory of ship collision avoidance, as one parts of the system of active warning of ship-bridge collision avoidance, which can show the index of dynamic risk degree for vessels passing through bridge area. The index of ship-bridge collision can make more efficiency for the system of active warning of ship-bridge collision avoidance, which can ensure safety for vessels and bridges. The verification results show the application possibility of the model in practice.
