Abstract: To define lane-changing time accurately and quantitatively, the influence of vehicle spacing on lane-changing time was studied using cars. Taking into account the influence of surrounding vehicles’ spacing on lane-changing, a vehicle lane-changing time model on an urban road B-type weaving section based on a potential energy field theory was proposed. The model quantitatively illustrated the influence of surrounding vehicles’ spacing on lane-changing lateral acceleration and then deduced the relationship between the lateral displacement, longitudinal displacement and time of the lane-changing vehicle. By using the aerial data of passenger cars lane-changing in the weaving area of an urban trunk road, the parameters in the model were calibrated and the lane-changing trajectory of vehicles simulated by the model was tested. It is found that the accuracy of the lane-changing model to quantitatively define the transverse acceleration while changing lanes and the spacing between constrained regions reaches 90%, and the fitting degree between simulated lane change trajectory and actual lane change trajectory is over 90%. The results show that the vehicle lane-change model based on the potential energy field theory can effectively simulate the relationship between vehicle lane-change time and lateral and longitudinal displacement and can provide theoretical and technical support for traffic simulation and multi-vehicle interaction.
