Study On The Method Of Regional Perimeter Control Based On Network Energy Consumption And Traffic Efficiency

With the rapid growing of vehicle population,the problems of urban road traffic congestion and traffic energy consumption are becoming more and more serious.Therefore,a control method is necessary to be founded to reduce the vehicle fuel consumption and improve the traffic efficiency.In order to solve the above problems,perimeter control methods with lower vehicle fuel consumption and higher traffic efficiency were explored in this paper on the basis of the macroscopic fundamental diagram(MFD),which was supported by the National Natural Science Foundation of China “Eigen Extraction of Heavy Traffic Network and Rapid Evacuation Algorithm Based on the Temporal and Spatial Detection(No.61304195)”.The main research works of this paper are structured as the following aspects:1.Concerning the homogeneous network.(1)A multiple objective problem for the higher traffic efficiency and the lower vehicle fuel consumption was established based on the macroscopic fundamental diagram(MFD)and then solved.Moreover,according to the congestion problem of the perimeter intersections caused by the control of the feedback gating,the models of the location choice in the gating intersection and the traffic flow allocation algorithm were proposed in this paper which were integrated with the feedback gating to become a new control model called “SFPI feedback gating control method”.This new control method could be used to reduce the sub-area car fuel consumption and improve the road network vehicle completion.(2)Finally,the simulation network was set up to verify the proposed control method and compare with the traditional feedback gating control method.The simulation result shows that the new model could reduce fuel consumption significantly and improve vehicle completion rates.In addition,it could also solve the problem of the too long intersection queue length effectively and decrease the intersection delay and parking number.2.Concerning the heterogeneous network.(1)The heterogeneous network was divided into a number of homogeneous sub-regions and a dual objective problem model for multiple sub-regions was established based on the macroscopic fundamental diagram(MFD)and then solved.What's more,the SFPI feedback gating control method of multiple sub-regions was put forward based on the SFPI feedback gating control method of single sub-region to reduce fuel consumption and improve vehicle completion rates.(2)Finally,the effectiveness of the proposed control method was verified through the simulation network.
