【摘要】：根据终端区空域运行规则,采用网络理论建立了终端区空域网络模型,基于终端区航空器微观行为建立了空中交通流跟驰模型和等待模型,基于NetLogo仿真平台进行了仿真试验,分析了不同入度分布的空域结构对交通流的影响。仿真结果表明:当密度小于等于0.075架次·km-1,速度大于等于0.04km·s-1时,交通流处于自由相;当密度为0.075~0.200架次·km-1且速度大于等于0.04km·s-1时,交通流处于畅行相;当密度大于0.200架次·km-1,小于最大密度时,交通流处于拥塞相;随着航班波作用的减弱,交通流进入反向畅行相,之后进入反向自由相;当进场交通流分布一定,入度值依次为2、3、1时,交通流速度小,密度大,拥塞消散最慢,入度值依次为3、2、1时,交通流速度大,密度小,拥塞消散最快。可知,增大空域网络上游关键节点的入度,使进场交通流提前完成汇聚,有利于交通流快速运行,增大交通流量;减小空域网络下游关键节点的入度,有利于交通流在达到拥塞相后快速完成消散。
[Abstract]:According to the operational rules of terminal airspace, the terminal airspace network model is established by using network theory, the air traffic flow following model and waiting model are established based on the micro behavior of terminal area aircraft, and the simulation experiments are carried out based on NetLogo simulation platform. The influence of spatial structure with different degrees of entry on traffic flow is analyzed. The simulation results show that the traffic flow is in the free phase when the density is less than or equal to 0.075 km-1 and the speed is greater than or equal to 0.04km s ~ (-1), and when the density is 0.075 ~ 0.200 km-1 and the speed is greater than or equal to 0.04km s ~ (-1), the traffic flow is in the free phase. When the density is greater than 0.200 km-1, when the maximum density is less than the maximum density, the traffic flow is in the congestion phase; with the weakening of the flight wave, the traffic flow enters the reverse free phase, and then the reverse free phase; when the traffic flow distribution is constant, The traffic flow velocity is small, the density is high, the congestion dissipation is the slowest, and the traffic flow velocity is large, the density is small, and the congestion dissipates the fastest, and the entry value is 3 ~ 2, 1 in turn, the traffic flow speed is large, the density is small, and the congestion dissipates the fastest. We can know that increasing the entry degree of the key nodes in the upstream of the airspace network, so that the traffic flow converges ahead of time, is conducive to the rapid operation of the traffic flow, increases the traffic flow, and reduces the entry degree of the key nodes in the downstream of the airspace network. It is advantageous for the traffic flow to dissipate quickly after reaching the congestion phase.
