The invention relates to a road network risk assessment method based on a bad driving behavior risk of a bicycle. The method comprises the following steps: 1) collecting driver information data, roadnetwork traffic data, road network environment data and road network data in a preset time window as original data; 2) performing standardization processing on different types of data sets to form a data feature set; 3) constructing a bicycle risk assessment model, and calculating a bicycle risk level; 4) establishing a road section risk assessment model by using a multi-level assessment method ofan entropy weight method, and obtaining the risk level of each road section in the road network under a preset time window; and 5) based on output results of the single vehicle risk assessment modeland the road segment risk assessment model, constructing a risk assessment model of the travel path, and obtaining a road network risk level. Compared with the prior art, the traffic accident risk ofthe road network can be measured in real time, and the acquisition accuracy and convenience of the road section and road network risk in the driving track are improved.

    本发明涉及一种基于单车不良驾驶行为风险的路网风险评估方法,包括步骤:1)采集预设时间窗内的驾驶员信息数据、路网交通数据、路网环境数据和路网数据作为原始数据;2)对各不同类型的数据集进行标准化处理,形成数据特征集;3)构建单车风险评估模型,计算单车风险水平;4)利用熵权方法的多层次评价方法建立路段风险评估模型,获取预设时间窗下的路网中各个路段的风险水平;5)基于单车风险评估模型与路段风险评估模型的输出结果,构建出行路径的风险评估模型,获取路网风险水平。与现有技术相比,本发明可实时度量路网的交通事故风险,改善行驶轨迹中的路段与路网风险的获取准确度和便利性。
