The invention relates to the field of traffic safety and risk assessment, in particular to a multi-element multi-scale highway traffic operation risk assessment method and device, and the method comprises the following steps: S1, determining the assessment index of each risk factor through recognizing the risk factors of highway traffic operation; s2, calculating a subjective weight and an objective weight of the evaluation index, and calculating an optimal combination weight of the evaluation index according to the subjective weight and the objective weight; s3, according to the optimal combination weight, calculating comprehensive determinacy of road traffic operation under different risk levels; and S4, comparing the comprehensive certainty degrees under different risk levels, wherein the risk level with the maximum comprehensive certainty degree is the risk level of road traffic operation. According to the method, through the steps of risk factor identification, weight calibration, cloud model analysis, risk analysis model establishment and the like, multi-dimensional information of various influence factors is fused, comprehensive risk assessment is carried out, and the influence of various risk factors on highway traffic operation can be systematically identified and quantified.

    本发明涉及交通安全、风险评估领域,特别是一种多要素多尺度公路交通运行风险评估方法及装置,方法包括以下步骤:S1、通过识别公路交通运行的风险因素,确定各风险因素的评估指标;S2、计算评估指标的主观权重和客观权重,根据主观权重和客观权重计算评估指标的最优组合权重;S3、根据最优组合权重计算公路交通运行的不同风险等级下的综合确定度;S4、比较不同风险等级下的综合确定度,综合确定度最大的则为公路交通运行的风险等级。本发明的方法通过风险因素的识别、权重标定、云模型分析、建立风险分析模型等步骤,融合各类影响因素的多维信息,进行全面风险评估,能够系统地识别和量化各类风险因素对公路交通运行的影响。
