Original abstract
Introduction This paper proposes a new cellular automaton traffic flow model capable of reproducing the concave growth pattern of traffic oscillations. Methods The randomization process is implemented through a power-law deceleration function to capture the diverse responses of drivers to disturbances. Using traffic stability as the performance metric, the model was calibrated with trajectory data from a 25-vehicle platoon. Results Simulation results indicate that the model can reproduce three typical traffic phases: free flow, synchronized flow, and congested flow. Meanwhile, the simulated maximum traffic flow is consistent with the empirical observations. Discussion These findings provide preliminary support for the effectiveness of the proposed stochastic deceleration mechanism in reproducing realistic traffic flow dynamics.
