車流率-
We use a colorful noise to describe traffic flow and regard it as the uncontrolled input ( equaled to noise ). then we use the multi - rate sampling pi controller to eliminate the error caused by noise, and make the length of queue stabilize at the threshold. the availability of the strategies and stability of systems are proved by doing some analysis and simulation
文中我們將一有色噪聲看作不可控輸入的擾動，採用基於pi的多采樣速率控制器以消除由此不可控輸入所造成的對系統輸出（交換節點緩沖區隊列長度）誤差的影響，使得系統輸出（隊列長度）穩定在閾值附近。 -
In the proposed flow control method for abr service in atm networks, by introduction of delay factors, the cell transmission rate for abr traffic with different rtd are adjusted differently when the surplus bandwidth varies, and the rate variation amplitude for the short rtd traffic will be enlargeed while one for the long rtd traffic will be lessened, compared with erica
改進的erica演算法加入時延因子，使在連接中具有不同時延的用戶在剩餘帶寬變化時，速率的調整具有不同反應，時延大的反應較遲鈍，時延小的反應較敏感。改進演算法使得小時延信源能更快的適應帶寬的變化，緩解了由於大時延信源速率調整的滯后而無法及時解除擁塞的現象。 -
The example analyzed in this thesis is the traffic impact analyzing for " reconstruction for commercial pedestrian street on chunxi road in chengdu city ", which belongs to the redevelopment of outdated city proper. having the present traffic situation through live investigation and predicting the promotive traffic flow after redevelopment, distributed in the road network, utilizing the method of artraction rate, the author obtain the service level after redevelopment to determine the necessity of reconstruction and presents some plans for redevelopment as well
在擁有大量數據的基礎上，應用實施tia的方法，通過吸引率法預測改造后的誘增交通量，獲得服務水平的變化，從而提出了與商業圈相關道路的改建方案：讓過境交通從步行街區外圍通過；將紅星路、東大街拓寬改善；署襪街、新街限時機動車通行；盡量減少商業圈內部機動車停車場，鼓勵周邊建造。 -
With regard to the flow regulation of the best - effort traffic, the controllable traffic in high speed computer communication networks, the present paper proposes a novel control theoretic approach that designs a proportional - integrative ( pi ) controller based on multi - rate sampling for congestion controlling. based on the traffic model of a single node and on system stability criterion, it is shown that this pi controller can regulate the source rate on the basis of the knowledge of buffer occupancy of the destination node in such a manner that the congestion - controlled network is asymptotically stable without oscillation in terms of the buffer occupancy of the destionation node ; and the steady value of queue length is consistent with the specified threshold value
本文從控制理論的角度出發，針對計算機高速網際網路中最大服務交通流即能控交通流的調節問題提出了一種基於多速率采樣的具有比例積分（ pi ）控制器結構的擁塞控制理論和方法，在單個節點的交通流的模型基礎上，運用控制理論中的系統穩定性分析方法，討論如何利用信終端節點緩沖佔有量的比例加積分的反饋形式來調節信源節點的能控交通流的輸入速率，從而使被控網路節點的緩沖佔有量趨于穩定;同時使被控網路節點的穩定隊列長度逼近指定的門限值。 -
Among them distributing with the traffic of average rate of increase law calculation flow of passengers capacity ; the flow of passengers is brought out in model law calculation with gravity ; constructing the rate sharing responsibility for building model calculation according to transportation resistance shifts the flow of passengers ; think over time value when the flow of passengers is brought out in the calculation
以膠濟鐵路提速改造為例，就構造的客運量預測模型作了應用研究。其中以平均增長率法計算客流量的交通分佈；以重力模型法計算誘發客流；依據運輸阻力構建的分擔率模型計算轉移客流；在計算誘發客流時考慮了時間價值。
