A modified cellular automaton model for traffic flow was proposed.A novel concept about the changeable security gap was introduced and a parameter related to the variable security gap was determined.The fundamental diagram obtained by simulation shows that the maximum flow more approaches to the observed data than that of the NaSch model,indicating that the presented model is more reasonable and realistic.
