平行跑道运行模式对终端区交通流特性的影响研究

为提升终端区空中交通运行效率,研究平行跑道运行模式对终端区交通流特性的影响.根据终端区空域结构特点、跑道运行规则,建立了终端区进场动态排序策略、进离场协调策略和航空器跟驰行为模型;选取国内某终端区标准进离场程序SID-STAR和双平行跑道构型,基于NetLogo仿真平台实现了终端区交通流运行仿真,对比分析了独立运行、相关运行和隔离运行典型跑道运行模式下终端区交通流特性参数的变化规律.结果表明:独立运行模式下终端区交通流运行效率较高但流量波动性较大,隔离运行模式下运行效率最低但最稳定;独立运行模式下终端区交通流的拥堵消散最快且延误最小,相关运行模式次之,隔离运行模式下终端区交通流的拥堵消散最慢且延误最大.

Impacts of Parallel Runway Operation Modes on Air Traffic Flow Characteristics in Terminal Areas

In order to improve terminal areas operation efficiency, runway operation mode impacts on air traffic flow characteristics is studied. Based on terminal area airspace structures and runway operation rules, a dynamic sequencing strategy for arrivals, a coordination strategy for arrivals and departures, and aircraft following behavior models are proposed. And then these strategies and models are simulated based on the platform of NetLogo with a terminal area in China, which adopted SID- STAR and had double parallel runways. The traffic flow characteristic parameters are analyzed under three typical runway operation modes, such as independent operation mode (IOM), related operation mode (ROM) and segregated operation mode (SOM). The simulation and analyzed results show that the IOM efficiency is higher but with bigger flow volatility, and the SOM efficiency is lowest but with little flow volatility; the IOM congestion dissipates most rapidly and its delay is also smallest, the SOM congestion dissipates slowest and its delay is also biggest.
