基于燃油消耗与交通效率的区域交通控制模型

The Traffic Control Model Based on Efficiency and Fuel Consumption of the Road Network

为了降低交通运输系统能源消耗,同时满足居民的出行需求,需综合考虑机动车燃油消耗和道路通行效率.针对此问题,引入交通网络车均燃油消耗和宏观基本图(Macroscopic Fundamental Diagram,MFD),建立了车辆完成率高、车均燃油消耗低的双目标规划模型,并对模型进行求解.依据反馈原理和车流平衡方程提出了燃油消耗比例积分控制(Fuel Consumption-Proportional Integral,FC-PI)控制方法,并通过FC-PI控制方法降低区域内车均燃油消耗,提高路网车辆完成率.最后通过实际城市路网验证所提出的燃油消耗控制模型,并且与Bang-Bang控制方法进行了比较.仿真结果显示,网络内车均燃油消耗显著降低,同时网络内车辆完成率得到提高,且FC-PI控制方法的控制效果要优于Bang-Bang控制方法.

In order to reduce energy consumption of the transportation system and meet the trip demand of the residents as possible. It is necessary to consider improving traffic efficiency under the condition of reducing vehicle fuel consumption. For the question, the average fuel consumption of the vehicles and macroscopic fundamental diagram（MFD） are introduced to establish the double- objective programming model, which makes the trip completion flow high but the average fuel consumption low, and the model is solved. Fuel consumption- proportional integral（FC- PI） control method is proposed based on the feedback principle and the equilibrium equations of the traffic flow, reducing the average fuel consumption of the vehicles in the region through the FC-PI control method, and improving the trip completion flow. Finally, the fuel consumption control model is verified by the actual urban road network as a case study, which is compared with the control method of Bang-Bang. The result shows that the trip completion flow is improved and the average fuel consumption of the vehicles is reduced significantly. And the control effect of FC-PI is better than Bang-Bang.
