The invention relates to the technical field of machine learning, and provides a student risk prediction method based on driving behavior modeling. The method comprises the following steps: acquiring a historical driving record based on big data; extracting a first mode record in the historical driving behavior mode; reading and processing the record according to a predetermined strategy to obtain a first behavior feature vector; introducing a risk assessment mechanism to analyze the feature vector to obtain a historical risk level; constructing a risk model according to the corresponding relationship between the feature vector and the risk level; dynamically monitoring real-time behavior characteristics of students, and obtaining an initial real-time risk level through model analysis; and calibrating the initial risk level according to the multi-dimensional risk factor set to obtain a target real-time risk level, and generating a dynamic risk distribution diagram of the target trainee so as to solve the problem that the behavior risk of the driving trainee in different environments and road conditions cannot be accurately evaluated by the existing driving behavior analysis method. And the real-time performance and the accuracy of risk assessment are not enough.
本申请涉及机器学习技术领域,提供基于驾驶行为建模的学员风险预测方法。所述方法包括:基于大数据获取历史驾驶记录;提取历史驾驶行为模式中的第一模式记录;读取并按预定策略处理记录,得到第一行为特征向量;引入风险评估机制分析特征向量,得到历史风险级;根据特征向量与风险级的对应关系构建风险模型;动态监测学员实时行为特征,通过模型分析得到初始实时风险级;根据多维风险因子集校准初始风险级,得到目标实时风险级,并生成目标学员的动态风险分布图,以解决由于现有驾驶行为分析方法无法准确评估驾驶学员在不同环境和道路条件下的行为风险,导致风险评估的实时性和准确性不足的技术问题。
