Abstract: Based on the tradition safety distance models for vehicle avoidance in the braking process,the model on the safety distance is established inconsidering of the speed relationship between the front and the latervehicle,and the gradual process of vehicle deceleration.Simulation done with Matlab verified this model could resolve the inaccurate defects in computing safety left by the tradition model in theory.At last,an intersection traffic-wave simulation system is established taking Visual C++ 6.0 as software development platform,and the results.Show that the modified model can improve the efficiency of the road and reduce the traffic pollution and intersection total delayundercondition that the safe distance production is ensured.

Key words: traffic engineering, car-following model, simulation, safe distance, braking
