In resent years cellular automaton car - following models are the basic car - following models. Researchers made lots of changes to the classic cellular automaton rules and different kinds of car - following models based on cellular automaton have been found thus. Still cellular automaton car - following models have their shortcomings. Firstly cellular automaton car -following models are discrete. Secondly, in a cellular automaton car - following model a following car might accelerate or decelerate which is different from that of a rsa! Case. To overcome these faults, an improved built - in beam I-maginary slope car - following model was proposed. In the proposed model the upper limit of the velocity of a following car may vary but approaches to zero as its distance to the leading car approaches to zero. It was tested by a real simulation instance and good results were obtained.
