Abstract

The invention discloses a vehicle lane changing track deviation calculation method based on traffic simulation, and the method comprises the steps: obtaining a real lane changing track and simulation lane changing track information of a target vehicle, calculating the deviation between the simulation lane changing track and the real lane changing track in lane changing time, longitudinal length and transverse length, and calculating the deviation between the simulation lane changing track and the real lane changing track; and finally determining the total deviation of the real lane changing track and the simulated lane changing track of the target vehicle when the deviation of the simulated lane changing track and the real lane changing track in the whole process stages of the speed, the acceleration and the steering angle is calculated. According to the method provided by the invention, the macroscopic parameters and the microscopic parameters in the microscopic lane changing track are comprehensively considered, and the microscopic parameters are uniformly processed in the time dimension, so that the deviation between the simulated lane changing track and the real lane changing track can be more accurately evaluated, and technical guidance is provided for further optimizing a lane changing model or a traffic simulation platform.

Description

technical field [0001] The invention relates to the field of intelligent traffic control, in particular to a traffic simulation-based calculation method for vehicle lane change trajectory deviation. Background technique [0002] The complexity of traffic determines that large-scale repeated experiments cannot be carried out. Therefore, traffic simulation is an effective means to predict traffic status and test traffic control strategies. The data collected in the real world is used to calibrate the simulation model, and then the simulation model simulates real or future traffic scenarios to obtain simulation data. Before evaluating the implemented traffic control strategy, the simulation effect should also be evaluated to ensure the effectiveness of the simulation model and the scientific nature of the simulation results. The lane change model is one of the core models. Based on the real lane change trajectory, the evaluation method of the simulated lane change trajectory i...
