The invention discloses a driving risk assessment method and device based on driving behaviors. The method comprises the following steps: S1, acquiring parameter data and risk assessment indexes which influence the driving behaviors of a driver; s2, performing feature processing on the driving behavior parameter data of the driver in the step S1; s3, obtaining a logistic regression function; s4, establishing a driving risk assessment model; s5, performing model training on the driving risk assessment model based on a data set formed by the driver driving behavior parameter data after feature processing; and S6, performing driving behavior risk assessment based on the trained driving risk assessment model, and performing optimization suggestion on the driving behavior based on the importance parameters. According to the driving risk assessment method and device based on the driving behavior, the driving behavior of the driver and the risk caused by other surrounding environment factors to the fine-grained driving behavior can be comprehensively considered, the risk of the driving behavior of the driver is analyzed more finely, and optimization suggestions are given.

    本发明公开了一种基于驾驶行为的驾驶风险评估方法及装置,包括以下步骤:S1、获取影响驾驶员驾驶行为的参数数据和风险评估指标;S2、对步骤S1中的驾驶员驾驶行为参数数据进行特征处理;S3、获取逻辑回归函数;S4、建立驾驶风险评估模型;S5、基于特征处理后的驾驶员驾驶行为参数数据形成的数据集,对驾驶风险评估模型进行模型训练;S6、基于训练后的驾驶风险评估模型进行驾驶行为风险评估,基于重要性参数对驾驶行为进行优化建议。本发明采用上述的一种基于驾驶行为的驾驶风险评估方法及装置,可综合考虑驾驶员自身驾驶行为以及其他周边环境因素对细粒度驾驶行为造成的风险,更加精细化地分析驾驶员驾驶行为的风险并给出优化建议。
