This paper studied three traffic rules under the situation of highway straight using the idea of cellular automata, and established the cellular automaton model of two-lane highway (situation of highway straight) for running but not allowing overtaking, the cellular automaton model of two-lane highway (situation of highway straight) for running on the right side and overtaking from the left side, and cellular automaton model of two-lane highway (situation of highway straight) for running on both sides and freely overtaking. This paper defines the concepts such as congestion probability, free passage probability, vehicles entering the highway probability, etc, in which, the congestion density is used to characterize the security of road traffic (the greater the congestion probability is, the less safety); free passage probability is used to evaluate the highway traffic capacity (the greater is the free passage probability, the better is the highway traffic capacity). Based on the simulation results, we can know about the two-lane freely overtaking rules have some effect in improving highway safety and traffic capacity.
