Abstract：In order to improve the micro driving behavior resolution of a traffic cellular automaton(TCA) model, an intelligent driving model(IDM) embedded in TCA was proposed to form a new intelligent car-following traffic cellular automaton(ICTCA) model. Based on the definition of cell-spatial granularity, perturbation experiments were designed to simulate the car-following hysteresis behavior of a platoon leaving the intersection with small disturbances. The results showed that the new model has the ability to resolve the car-following hysteresis, and the finer the cell-spatial granularity, the more stable hysteresis effect can be obtained, indicating that the proposed model has the micro driving behavior resolution close to that of the continuous car-following model under appropriate cell-spatial granularity. Inheriting the characteristics of IDM and TCA, the new model has more possibilities to be applied to intelligent networking scenarios.
