Intelligent traffic dispatching and commanding and information service method and system based on dynamic information

The invention discloses intelligent traffic dispatching and commanding and information service method and system based on dynamic information. The method comprises the following steps of: collecting basic traffic data; normalizing the time, the space and the attributes of the basic traffic data; periodically evaluating and predicting the traffic state of the entire road network; periodically comparing the traffic state evaluation results and the historical data of the road network, and sending a warning prompt to a commander in case of exceeding a certain threshold; responding to a confirmed warning prompt, and creating a breakdown lorry dispatching scheme; and responding to the confirmed warning prompt and the evaluated and predicted road network traffic state, judging whether a serious traffic jam occurs, and creating and releasing abnormal traffic information or normal traffic information. The invention can increase the utilization ratio of the basic traffic data, can enhance the contact between the urban traffic command center and the 110 command center, and can improve the working efficiency of personnel in the command centers and the travelling efficiency of travelers.
