【摘要】：闡明機場場面交通流時空演變規(guī)律,揭示離場交通流擁堵機理是科學(xué)制定場面交通流管控策略的重要基礎(chǔ)。采用元胞傳輸機理論,建立線性滑行道元胞、機坪發(fā)散/交叉元胞、匯聚元胞的交通流傳輸模型,并基于NetLogo系統(tǒng)動力學(xué)仿真平臺,以廣州白云國際機場為例驗證了模型的有效性,進而推演分析了離場交通流基礎(chǔ)相變特征及其影響機理。研究表明,場面離場交通流存在自由態(tài)、亞穩(wěn)態(tài)、擁堵累積態(tài)和擁堵死鎖態(tài)4種基礎(chǔ)相態(tài),指出調(diào)節(jié)與進場率相協(xié)調(diào)的推出率是有效控制離場交通流密度,緩解場面擁堵的重要手段。研究結(jié)果可為大型繁忙機場場面交通智能管控提供一定的理論基礎(chǔ)和決策參考。
[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.
