The invention relates to the technical field of traffic safety, in particular to a highway risk map construction method and device fusing multi-source data, and the method comprises the following steps: S1, selecting a traffic conflict risk, a driving behavior risk and a vehicle safety risk as risk dimensions, selecting risk indexes according to the traffic conflict risk, the driving behavior risk and the vehicle safety risk, and calculating risk index data and the weight of the risk indexes; s2, calculating the total risk of the road section according to the weight of the risk dimension, the weight of the risk index and the risk index data; and S3, obtaining a risk map according to the total risk of the road section and the weight of the risk dimension. According to the method, by constructing the risk map and identifying the high-risk area, the application of multi-source data fusion in the aspect of highway risk assessment is enhanced, a scientific basis and technical support can be provided for traffic safety management, and the safety of the highway is improved.

    本发明涉及交通安全技术领域,特别是一种融合多源数据的高速公路风险图谱构建方法及装置,方法包括以下步骤:S1:选取交通冲突风险、驾驶行为风险和车辆安全性风险作为风险维度,根据交通冲突风险、驾驶行为风险和车辆安全性风险选取风险指标,并计算风险指标数据和风险指标的权重;S2:根据风险维度的权重、风险指标的权重和风险指标数据计算路段总风险;S3:根据路段总风险、风险维度的权重得到风险图谱。本发明的方法通过构建风险图谱,识别高风险区域,加强了多源数据融合在高速公路风险评估方面的应用,能够为交通安全管理提供科学依据和技术支持,提升高速公路的安全性。
