空中高速路匝口流量控制

Research on Air Highway Ramp Flow Control

空中高速路系统有助于缓解日益严重的空中交通拥挤问题。从空中高速路及其匝口的基本概念入手,基于元胞传输理论建立了空中高速路匝口流量控制模型,通过对模型进行仿真求解,建立匝口元胞连接图,得到系统最短时间、系统清空时间、最优匝口流量分布等,结果表明:该模型既能够满足空中高速路匝口流量控制建模的需要,又能反映空中高速路系统中交通流的动态特性。

With the rapid development of the air transportation,air traffic will become heavier and heavier, establishing air highway is important to alleviate the increasingly serious problem of air traffic congestion. This paper gives a basic concept of air highway and of ramp, using the basic theory of cell transmission model to present an air highway ramp flow control model. By solving this model, the system minimum time, system clearance time, optimal flow distribution of ramp, and so on are obtained. Results of a case study show that this model can meet the modeling demand of air traffic highway ramp flow control, and al- so can describe the dynamics feature of traffic flow in air highway system.
