On the basis of the research of two traditional safety distance models which based on headway and braking process, In connection with the leading vehicle in static, uniform speed, and uniform deceleration driving states, a model of minimum safety distance for collision avoidance between the following and the leading vehicles was established considering the vehicle gradual deceleration in braking process for avoiding deceleration mutation in the old models. At last, the simulations for the improved model and the traditional one were performed with Matlab under the same condition. The simulation data shows that the improved model could resolve the inaccurate defects in computing safety distance by the tradition models and provide a reference for the future research of car-following model.
