The invention discloses a road risk assessment method fusing OBD and GPS multi-source Internet of Vehicles data. The method comprises the following steps: acquiring OBD data and GPS data of each vehicle running in a monitored road section i within unit time; the OBD data and the GPS data are fused, and the abnormal driving probability Pi of the monitored road section and the proportion Qi of high-risk drivers in the monitored road section are calculated; and calculating the risk value Ri of the monitored road according to the abnormal driving probability Pi of the monitored road section and the high-risk driver proportion Qi in the monitored road section. According to the method, the abnormal driving probability and the high-risk driver proportion in the monitored road section are analyzed by fusing OBD and GPS multi-source Internet of Vehicles data, and then the road risk is comprehensively evaluated according to the abnormal driving probability and the high-risk driver proportion in the monitored road section. The road static property and the road static property are comprehensively considered in the assessment process, and the risk assessment accuracy can be effectively improved.

本发明公开了一种融合OBD、GPS多源车联网数据的道路风险评估方法，包括以下步骤：获取单位时间内在监测路段i中行驶的各车辆的OBD数据及GPS数据；将OBD数据及GPS数据进行融合，计算该监测路段的异常驾驶概率Pi和监测路段中的高风险驾驶人员比例Qi；然后根据监测路段的异常驾驶概率Pi以及监测路段中的高风险驾驶人员比例Qi计算该监测道路的风险值Ri。本申请通过融合OBD、GPS多源车联网数据，对监测路段中的异常驾驶概率及高风险驾驶人员比例进行分析，然后根据监测路段中的异常驾驶概率及高风险驾驶人员比例综合对道路风险进行评估，本申请在评估过程中综合考虑了道路静态属性和道路静态属性，可有效提高风险评估准确性。
