The Driver Workload Prediction Systems (DWPSs) proposed so far learn either from individual driver’s data (termed
personalized system) or existing drivers’ data indiscriminately (termed average system). As a result, they either do not work or lead to a limited performance for new drivers without
labelled data. To this end, we develop clustering-aided approaches exploiting group characteristics of the existing drivers’ data. Two clustering aided predictors are proposed. The first is Clustering Aided Regression (CAR) model, where the regression model for the cluster with the highest likelihood is adopted. The second is Clustering-Aided Multiple Model Regression (CAMMR) model, where the concept of multiple models is further augmented to CAR. A recent dataset from real-world driving experiments is adopted to validate the algorithms. Comparative results against the conventional average system demonstrate that by incorporating clustering information, both the proposed approaches significantly improve workload prediction performance.
