The load of large-size vehicles has not been clearly defined in the existing bridge design codes in our country. When large-size vehicles cross the bridge, the bridge has certain safe-ty hazards. At present, there are not many evaluation methods for the driving safety of large-size transportation bridge structures. In order to scientifically evaluate the traffic safety of the large-size transportation bridge structure, this paper considers the factors of bridge, traffic and environment, and establishes the evaluation index system for the operation safety of the large-size transportation bridge structure, using the comprehensive weighting method of the G1-entropy weight method. Calculating the weight and combining the fuzzy comprehensive evaluation method to evaluate the traffic of the large-scale transportation bridge in Huanglong County, Shaanxi Province, the results show that the traffic safety level of the bridge is level II, which has good safety.
