The purpose of this paper is to extend the existing Cellular Automata (CA) models and to use the extended CA models to describe the influence of a car accident in single-lane and two-lane traffic flow. To evaluate dynamic traffic flow, the authors developed a traffic flow simulator that uses CA model. It is shown that the single-lane dynamics can be extended to the two-lane case without changing the basic properties of the model. The two-lane model considered here shows quantitative improvements over the single-lane model. They also add the lane changing rules to simulate the reality traffic condition.
