Vehicle driving behavior analysis and unified modeling in urban road scenarios
In order to improve the simulation accuracy and efficiency of microscopic urban traffic,a unified modeling method considering the behavioral characteristics of vehicle driv-ers is proposed by taking the lane-changing vehicles on the inlet lanes of signalized intersec-tions and the following vehicles on the target lanes as the research objects.Based on the driver's multidirectional multi-vehicle anticipation capability and introducing lateral vehicle influence coefficients,the full velocity difference car following model was extended to the microscopic traffic model that can describe the longitudinal movements of lane-changing ve-hicles and following vehicles during lane changing.The influence of traffic control signals and types of lane changing on drivers'decisions were integrated into the model by reformu-lating the optimal velocity function of the basic car following model.Results show that in the process of lane changing car following behavior is more sensitive to the status of lateral mov-ing vehicles and the change of lane-changing types than to the lane changing behavior,and the driver's chief attention to external stimuli changes in different types of lane change sce-narios.Compared with Gipps model,full velocity difference car following model is more suitable to be taken as the basic model to simulate microscopic urban traffic.
