【摘要】：首次運(yùn)用經(jīng)濟(jì)學(xué)非瓦爾拉斯均衡中的價(jià)格-數(shù)量調(diào)節(jié)原理和方法,建立網(wǎng)絡(luò)交通流動(dòng)態(tài)演化模型.假設(shè)出行者在路徑選擇決策時(shí),不但受路徑出行時(shí)間(價(jià)格)的影響,而且還受到路徑剩余通行能力(數(shù)量)的影響,并將這種路徑選擇行為形成的穩(wěn)定交通流模式定義為價(jià)格-數(shù)量混合調(diào)節(jié)用戶均衡.論文分別建立了價(jià)格調(diào)節(jié)演化模型和數(shù)量調(diào)節(jié)演化模型,進(jìn)而構(gòu)建了價(jià)格-數(shù)量共同調(diào)節(jié)演化模型,證明了演化模型的穩(wěn)定狀態(tài)等價(jià)于價(jià)格-數(shù)量調(diào)節(jié)用戶均衡,且價(jià)格調(diào)節(jié)用戶均衡和數(shù)量調(diào)節(jié)用戶均衡均為價(jià)格-數(shù)量調(diào)節(jié)用戶均衡的特例.論文最后以一個(gè)簡單的測試網(wǎng)絡(luò)為例對文中建立的演化模型進(jìn)行了計(jì)算分析,結(jié)果顯示三種演化模型均可較理想地模擬路徑流隨時(shí)間變化的過程,且模型穩(wěn)定狀態(tài)分別對應(yīng)三種用戶均衡交通流模式.
[Abstract]:Based on the price-quantity regulation principle and method of non-Walras equilibrium in economics, the evolution model of network traffic flow is established for the first time. It is assumed that the traveller is not only affected by the route travel time (price), but also by the path choice decision. It is also affected by the residual capacity of the path (quantity), The stable traffic flow model formed by the path selection behavior is defined as the price-quantity mixed regulation user equilibrium. In this paper, the price regulation evolution model and the quantity regulation evolution model are established, respectively. Furthermore, the evolution model of co-regulation of price and quantity is constructed, and it is proved that the stable state of the evolution model is equivalent to the price-quantity adjustment user equilibrium. The price adjusting user equilibrium and the quantity regulating user equilibrium are special cases of price and quantity adjustment user equilibrium. Finally, a simple test network is taken as an example to calculate and analyze the evolution model established in this paper. The results show that the three evolution models can simulate the process of path flow changing with time perfectly, and the stable state of the model corresponds to three user equilibrium traffic flow modes respectively.
