摘要: 驾驶员行为的不确定性为高级驾驶辅助系统的应用带来挑战。为更加准确预测驾驶员的换道行为,通过深入研究多层感知机(MLP)深度学习算法与支持向量机(SVM)算法,设计了MLP-SVM预测算法,应用于驾驶员换道行为预测。基于驾驶车辆信息和周围交通环境信息建立驾驶员换道行为预测模型,并采用公开实车驾驶数据集进行验证。研究结果表明,基于MLP-SVM的驾驶员换道行为预测模型,与分别基于MLP或SVM的驾驶员换道行为预测模型对比,取得的最高预测准确率为92.6%,可更早预测出换道行为,提前预测时间可达4.54 s。

Abstract: The uncertainty of human driver behavior brings challenges to the application of advanced driver assistance systems. In order to more accurately predict the lane-changing behavior of a driver, we studied the multi-layer perceptron (MLP) and the support vector machine (SVM), and designed the hybrid algorithm of MLP-SVM to predict the lane-changing behavior of the driver. Based on the vehicle information and the surrounding traffic environment information, the prediction model of driver's lane changing behavior is built. The real traffic dataset is used to verify the proposed model. The results show that compared with the prediction model of driver's lane changing behavior based on support vector machines or multi-layer perceptrons, the hybrid prediction model of driver's lane changing behavior achieves the highest prediction accuracy of 92.6%, and can predict the lane changing behavior earlier with the advanced prediction time up to 4.54 s.
