摘要：

According to the distribution of road network traffic status, the decision of traffic state transition risk is an important basis for sub-region traffic guidance and control. The macroscopic fundamental diagram (MFD) can effectively describes the macroscopic characteristics of the road network without needs the complex OD data, which provides an opportunity to solve the decision problem. Therefore, regard the characteristics of MFD as the basis and consider the influence of the driver's route decision on the traffic state of the sub-regions under the guidance and control conditions, a risk decision model is established to control the traffic state risk and cost of the MFD sub- regions. The decision model takes the maximum completion rate and minimum total travel time as constrains according to the fuzzy risk management model, and is solved by the ALRS algorithm. Simulation results show that the model can effectively improve the efficiency of control and guidance, and maintain the real-time and effectiveness of traffic control in the case of a sudden incident.
