【摘要】：阐明机场场面交通流时空演变规律,揭示离场交通流拥堵机理是科学制定场面交通流管控策略的重要基础。采用元胞传输机理论,建立线性滑行道元胞、机坪发散/交叉元胞、汇聚元胞的交通流传输模型,并基于NetLogo系统动力学仿真平台,以广州白云国际机场为例验证了模型的有效性,进而推演分析了离场交通流基础相变特征及其影响机理。研究表明,场面离场交通流存在自由态、亚稳态、拥堵累积态和拥堵死锁态4种基础相态,指出调节与进场率相协调的推出率是有效控制离场交通流密度,缓解场面拥堵的重要手段。研究结果可为大型繁忙机场场面交通智能管控提供一定的理论基础和决策参考。
[Abstract]:It is important to expound the temporal and spatial evolvement law of airport traffic flow and reveal the mechanism of traffic flow congestion in departure field, which is an important basis for scientifically formulating the control strategy of scene traffic flow. The traffic flow transmission model of linear taxiway cell, apron divergent / cross cell and convergent cell is established by using cellular transmission machine theory, and based on NetLogo system dynamics simulation platform. Taking Guangzhou Baiyun International Airport as an example, the validity of the model is verified, and the basic phase transition characteristics and its influence mechanism of the departing traffic flow are deduced and analyzed. The results show that there are four basic phase states: free state, metastable state, congestion accumulation state and congestion deadlock state. It is pointed out that the ejection rate of adjusting and approaching rate is effective to control the departure traffic flow density. An important means to ease congestion. The results can provide a theoretical basis and decision reference for traffic intelligent control in large busy airports.
