摘要: 针对现有驾驶分神识别方法存在的精度与成本兼顾难、分神程度识别能力弱的问题,本文提出基于麻雀搜索优化XGBoost算法的驾驶员分神类型与程度分层识别方法。首先,系统性提取视觉、认知分神驾驶下驾驶行为、眼动与生理等46项特征指标,采用重复测量方差分析与效应量比较遴选视觉、认知分神高灵敏度指标,构建面向驾驶分神类型与程度识别的高灵敏性指标集。其次,采用递归特征消除算法对驾驶性能、视觉及生理等多源指标进行二次优选,构建仅涵盖驾驶行为指标的单一特征集与涵盖驾驶行为、眼动、生理多源指标的多源特征集。而后,建立驾驶分神类别与程度分层识别框架,采用麻雀搜索算法对XGBoost模型进行超参数寻优构建各层分类器。最后,系统性对比单一特征集与多源特征集作为输入时模型的识别效果,构建低成本高精度的驾驶分神类型与程度识别模型。结果表明,在分神类型识别上,单一特征集与多源特征集模型的准确率分别达到了92.4%和95.9%,均表现出优异性能;此外,经麻雀搜索算法优化的分神类型识别模型相比于支持向量机、随机森林与常规XGBoost等模型准确率分别提升4%~6%、11%、7%。在分神程度识别上,多源特征集模型对认知与视觉分神程度识别准确率较高,分别达到了81.0%和84.9%,而单一特征集模型识别准确率较低。因此,推荐采用单一特征集模型实现分神类型的低成本识别,采用多源特征集模型实现分神程度的高精度识别。所提出的方法可实现驾驶分神类型与程度的低成本高精度识别,可为不同应用场景下的驾驶员状态监测系统开发提供理论支撑。

Abstract: To improve the existing detection methods for driver distraction in balancing accuracy with cost and identifying distraction levels, this paper proposes a hierarchical recognition method using XGBoost and Sparrow Search Algorithm. The study extracted 46 features from driving behavior, eye movement, and physiological data during visual and cognitive distraction. Highly sensitive indicators for distraction type and degree were selected through repeated-measures Analysis of Variance (ANOVA) and effect size comparisons to build a high-sensitivity feature set. A recursive feature elimination algorithm was then applied for secondary feature selection from multi-source indicators, resulting in two distinct sets: a single-source feature set containing only driving behavior features and a multi-source feature set integrating driving behavior, eye movement, and physiological features. A hierarchical recognition framework was established, employing the Sparrow Search Algorithm to optimize hyperparameters of the XGBoost classifiers at each level. The study also evaluated the model performance using the single-source and multi-source feature sets as input to develop a low-cost, high-accuracy model. Results demonstrate that for distraction type recognition, the single-source and multi-source models achieved accuracies of 92.4% and 95.9%, respectively. The Sparrow Search Algorithm optimized model for type recognition consistently outperformed Support Vector Machine, Random Forest, and standard XGBoost models, with accuracy improvements of 4%~6%, 11%, and 7%. For distraction degree recognition, the multi-source model achieved the accuracies of 81.0% for cognitive and 84.9% for visual distraction, while the single-source model showed relatively poor performance. Therefore, the single-source model is recommended for low-cost type recognition, and the multi-source model for high-precision degree assessment. The proposed method enables cost-effective and accurate identification of driver distraction, providing theoretical support for developing context-aware driver state monitoring systems.
