考虑驾驶风格与车辆交互关系的自由换道决策模型
A Free Lane-changing Decision Model Considering the Driving Style and the Interaction with Peripheral Vehicles
摘要
Abstract
The interactions between lane-changing vehicle and peripheral vehicles will influence the lane-changing decision behavior.In response to this,a lane-changing decision model that integrates driving styles and interactions is developed based on the lane-changing utility.Utilizing the extreme gradient boosting(XGBoost)algorithm and the density-based spatial clustering of applications with noise(DBSCAN)clustering method,drivers'short-term driving styles are categorized into conservative,typical,and aggressive types.Based on traffic conflicts of trajecto-ries,the spatiotemporal overlap points between vehicles are determined to classify interactions.A utility quantifica-tion model is constructed across three dimensions:speed enhancement,spatial safety,and temporal safety.The weights of three sub-utilities are calculated based on MIC,then a total utility model for lane-changing decision is es-tablished.Using historical data,the total utilities of lane-changing drivers are computed in comparison to that of lane-keeping drivers,resulting in the identification of lane-changing utility thresholds.Thereby rules for lane-chang-ing decision are formulated.The result of model's accuracy indicates that the model considering interactions signifi-cantly outperforms the model that does not,underscoring the importance of interactions in lane-changing decision.Predictions of lane-changing behavior are conducted using the radial basis function(RBF)model and XGBoost model.For conservative,typical,and aggressive drivers,accuracies of the RBF method are 0.885,0.820,and 0.813,while the XGBoost method achieves accuracies of 0.954,0.902,and 0.900.AI models demonstrate high predictive accuracies for lane-changing decision across all driver types.However,the predictive accuracies for the typical and aggressive drivers are lower than that of the decision model proposed in this paper(0.921 and 0.923,respectively).Additionally,non-parametric statistical tests of lane-changing utilities further validate the rationality of the model.关键词
