The velocity limit signal often occurs because of bad traffic road infrastructure. Therefore, a novel lattice hydrodynamics model is provided by combining the velocity limit effect under V2X environment. The linear stability analysis reveals that the stability conditions are closely related to the velocity limit effect. Moreover, the evolution of density and hysteresis loop have been deeply explored in this paper via simulation. Interestingly, it is valuable to correctly consider the impact of velocity limit on traffic flow, which can play a positive role on traffic stability.
