| Abstract: | In order to make accurate and real-time prediction of traffic state, the factors influencing traffic is analyzed and the decision tree algorithm is adopted to model the data of velocity and environmental factors to determine the rules of traffic congestion. Then, according to the real-time mobile users and environmental factors data, the traffic state is predicted with the generated rules. Experiment in Baoding City, Hebei Province proves the effectiveness of the proposed method. It is also found that the method based on decision tree algorithm has a high expansibility. |
