The key of the drivers' behaviors are their driving decisions. To reveal the decision-making process, a new model with consideration of the deceleration limitation (DL) was built, based on a cellular automata (CA) model. In the DL model, the driver's decision was divided into three steps: decision-making, action and result. And the acceleration was taken as a decision variable and also two other core factors, i.e. distance between adjacent vehicles and their own velocity, were considered. Simulation results show that the DL model can simulate the interaction between vehicles realistically and describe the phase transition of traffic flow well. Further analyses illustrate that the density's change can cause the critical phase transition in traffic flow. These findings have effectively reproduced some realistic phenomenon and will help reduce the traffic congestion.
