Journal of Intelligent Computing Bai Yunxiao, Guo Gaihui 11 2 2020 https://doi.org/10.6025/jic/2020/11/2/63-71 http://www.dline.info/jic/fulltext/v11n2/jicv11n2_3.pdf Based on vehicle – following model, we propose a new traffic flow dynamics model from both micro and macro aspects. The model can overcome some of the problems that exist in the existing kinetic models, such as avoiding the phenomenon that the traffic jam occurs in the vicinity of the disturbance density, thus exceeding the blockage density. Through design of examples, the authors also simulated traffic flow under different conditions, which shows the model has good numerical simulation capabilities, thus proving its theoretical and practical value.
