多个MFD子区边界协调控制方法
Coordinated Method of Perimeter Control for Multiple MFD Sub-regions
摘要
Abstract
In order to improve the service level of urban road network,the macro traffic network is divided into multiple macroscopic fundamental diagram (MFD) sub-regions on the basis of different traffic densities,and then a coordinated perimeter control method is proposed.According to the relations of traffic flows among multiple MFD sub-regions,a balance equation of network traffic flow is established.Compared with the optimal cumulative traffic volume of the network,the optimal traffic inflow and outflow at the crowded intersections of sub-regions perimeter are determined.Moreover,a multi-objective programming model is set up,which takes the maximum average trip completion flow of vehicles,the minimum average travel time and the average delay of road network as the objectives.Adaptive genetic algorithm is used to solve the multi-objective function.An actual road network with 4 MFD sub-regions is tested,and the result shows that the proposed strategies are effective in improving the network efficiency and alleviating traffic congestion.关键词
