摘　　要：当车辆以较高的车速经过道路大半径弯道时,存在较大的行车风险。以道路大半径弯道为研究对象,结合弯道曲率半径、转弯角度和有用视线面积,并基于优劣解距离法对弯道行车风险进行评价,随后通过现场试验对评价结果的准确性进行验证,并通过皮尔逊相关系数进行相关性检验。结果表明:弯道曲率半径因子在弯道平均车速贡献中,影响权重为4.51%。转弯角度因子的权重占比38.68%,有用视线面积权重最大,占比56.81%。通过优劣解距离法对道路大半径弯道进行评价的结果,与现场试验测得的车速整体分布趋势相接近,皮尔逊相关系数为0.916。The risk of vehicles passing the large-radius road curves at a high speed is high.This paper took the large-radius road curves as the objective and combined them with the curvature radius,the turn angle,and the useful sight area.This paper evaluated the driving risks based on the Technique for Order Preference by Similarity to Ideal Solution(TOPSIS).Then the accuracy of the evaluation was verified by the field tests,and the correlation test was performed by Pearson's correlation coefficient.The results showed that in the contribution to the average vehicle speed of the road curve,the influencing weight of the curvature radius occupied 4.51%,the weight of the turn angle occupied 38.68%,and the weight of the useful sight area occupied 56.81%.The evaluation results using TOPSIS were similar to the field test results,and Pearson's correlation coefficient was 0.916.
